As mentioned in an earlier thread I am stocking up on crystals for overclocking. The first order arrived yesterday and will be listed shortly. But that's not the point of this thread.
I'd like to hear people's experiences overclocking their Amiga hardware. Id like to hear not only the traditional drop in replacement of the accelerator crystal, but extreme modifications. I am testing an unusual modification atm that has me experiencing quite impressive results.
So gimme stories:-)
-
Yeah,
I bought a stock Apollo 25Mhz '040 some years back. Knowing that '040's have cooling issues I overclocked it. First to 28Mhz, then 33Mhz and finally 40Mhz.
Worked a treat. At least it did until the chip fan decided to detach itself... I now am presented with a red screen upon startup.
Oops.
-
@PMC
Hum,
that was a bit excessive huh?
But i sense that if you reseat the ROM chips then you may revive the computer...
[It`s possible to mimic that screen with a nuclear EM pulse, though]
-
And buy a better fan/heatsink for it :-)
-
I overclocked a CS MK II to 80MHZ and used a liquid cooling block on it. It worked great all the way up to selling it and converting it back to a 50MHZ config.
-
I heard that someone got one of those SDRAM equipped CT060 cards for the Atari running at 100MHz. Now if there was a way to get one of those into an A1200 :-D
-
@Blob,
Well, it worked for over four years at 40Mhz with no problems with stability.
For good measure I installed a heatsink between the CPU and fan, but I foolishly failed to periodically check the adhesion between the heatsink and fan.
I'll check the ROMs as you suggest and will report back.
-
Is the Amiga 4000D schematics online anywhere? I have just about every shop manual except the A4000:-(
-
Try here http://www.ianstedman.co.uk/Amiga/schematics/schematics.html (http://www.ianstedman.co.uk/Amiga/schematics/schematics.html)
second one for 4000 downloads but its in iff format. :-?
This is a better one to get it from http://amiga.serveftp.net/schematics.html (http://amiga.serveftp.net/schematics.html) :-)
-
I am just wandering, I have an Apollo 030 Turbo Mk-III running at 40Mhz no FPU with 32meg Fastram, could this be overclocked to 50Mhz do you think, or is that out of the question?
Bye the way, I am using a heatsink and fan ontop of the cpu that came from a Pentium 233mhz., with the proper heatsink cream and an elastic band for just in case.
It dont actualy need this but I thought what the hell stick it on any way.
Never had a problem.....
Mike.... :-)

dont overclock blizzppc to 280mhz with ram setting all turned off..60ns **maybe** fine on some cards..
one of my blizzppc has stop seeing bvision & fast ram due-to the above overclock..
-
Well this is interesting..
System:
CSPPC 200 & 060/50 (not overclocked yet, stock speed)
Prometheus with Voodoo 3 2000 (not overclocked yet)
I have done one small, unusual modification that isn't even an overclock, and I am smoking all the 3D benchmarks on AmigaSpeed.de (http://www.amigaspeed.de.vu)! Those systems has faster CPUs and faster GFX cards. Hmm...
This is getting very interesting...Very interesting indeed...
-
@Red
Bus performance is *extremely* important for 3D applications on existing classic amigas using eg Warp3D.
The faster you can shovel data to the card the better. All existing voodoo3 cards (and believe it or not, even the permedia2 half of the time) can consume vertex data at a much faster rate than the bus can deliver it. On slower 680x0 systems you tend not to notice since the CPU is the bottleneck, but with faster CPUs (eg the PPC and fast 060's) the bus becomes the dominant factor in 3D performance.
-
if i remember the difference between 60ns & all the memory switched off on the blizzppc is as much as 3MB sec...you can see the diff in wipeout 2097..
ahi
800x600
060 overclocked 66.6
ppc 603e 280Mhz..overclocked
do not switch off memory on blizzppc at this speed..
-
As always, I do not recommend over-clocking a processor. In fact, some processor boards for the Amiga 2000 need to be "under-clocked". For instance, the Progressive 2000 / 040 board has a 25 MHz 68040 chip that is clocked at 28 MHz. It uses a 56 MHz crystal. I am looking for a 50 MHz crystal so I can clock this board at 25 MHz, like it should have been done to begin with. Then this board will be a lot more stable and will run much cooler. If you guys actually need a lot of speed, then get yourself a PC computer. The Amiga was designed to do WORK. It was not designed to be fast. To give you an idea of what I am talking about think about this: a car is faster then a locomotive, but a car can only pull 1 or 2 more cars. A locomotive can pull hundreds of cars. One was designed for speed and the other was designed to do actual work.

@BoingBoss
Bah humbug! Your Amiga 2000 Professional probably wouldn't benefit from overclocking, but there is nothing wrong with users tweaking their systems if they take some precautions. As for me I am seeing a 30% improvement in Quake II framerate, and I havn't even overclocked anything yet:-D
-
@redrumloa
Will you ever stop all the mistery, and tell us what kind of "magic" are you doing with your system ??? :-o
I'm really curious . . . and looking forward too to apply your "magic" in my BPPC for testing purposes ! :-D

All in due time.. Sorry if it sounds like I'm gloating, I'm not. I just want to not only perfect, but also verify what I'm doing is safe and does not affect stability etc.

@BoingBoss
Well, I agree in principle that an overclocked system can run hotter and be prone to unreliability, but there are methods of mitigating these factors.
Paying attention to cooling goes without saying, and you'll find that several accelerator cards are retailed new running at higher clock rates than is actually shown on the CPU. Amiga Format ran an article back in July / August 1998 when they researched the subject which might well be worth seeking out.
Fact is, there are people out there who want to play Quake or use CPU intensive image processing software on their Amigas. If they're willing to take the risk of irreversible damage to their CPU and take all practical precautions then fair play I guess.
-
If these people want to play Quake then they should get themselves a PC computer. The PC version of Quake is the best version of the game. The Nintendo 64 version of Quake is also really good. Quake II is actually much better then Quake and Star Trek Voyager Elite Force blows them both away. I have discovered that the most fun games on the PC are the following:
Doom II (Ranked # 1 game of all time)
Blood (Banned in most countries and states)
Shadow Warrior (Also Banned in most countries and states)
Duke Nukem v1.3 (Still played every day on Kali)
Star Trek Voyager Elite Force (Ranked Best Quake Style Game)
Vampire: The Masquerade Redemption (Ranked # 1 RPG Game)
Wings of Glory (Ranked # 1 WWI Flight Simulator)
If I am going to play these kinds of games, I am going to play them on my Pentium 4 PC computer, NOT an Amiga computer. I use my Amiga computers for what they were intended to be used for- Graphics, Music, and Classic Amiga Games. :-)
-
@Redrumloa
Fine. I'll be looking forward for your treasure reveal :)
But, if you need some help, and/or have any doubts, please consider asking me for some help, and i'll be very glad if i can actually do.
I'm an electronics technician, and sucessfully did many overclocks. In fact, i even did an 68k processor upgrade in my BPPC. It used to have an 040 25MHz processor, until i transplanted the 68060 50MHz that was in my Blizzard.
Now i have an BPPC 200MHz, overclocked to run at 240MHz, with a 68060 rununing at 66MHz, and a spare Blizzard 040, running at 35MHz, waiting for some spare time of mine, to be in another A1200, that is disassembled for now.
Hope to hear from you soon !!! :-D

Marcelo.

@Red
Please tell me you've overclocked the Voodoo3 card, or something simular that I can transplant onto my Mediator system. :-D

@DoomMaster
Your Car vs. Locomotive logic is flawed as they are completely different things, built for completely different tasks. A FASTER CPU of the same type, on the same board, will do MORE WORK, period. A 28MHz 040 is faster than a 25MHz 040, period.
As for reliability, I'd suggest it's your system, as the PP&S fan is sufficient to cool the very slightly overclocked CPU. Clocking the board down could cause more problems because it was designed to run at a certain speed.
-
Shaddow Warrior.. I have that game here, it is pretty damn fun
Too bad every PC my family buys claps out after 2 or so years (theyre silly and wont get a Mac)

Hi adolescent,

My system is an Amiga 2000 Series computer, the highest quality Amiga, so NO, my system is working just fine. The PP&S 2000/040 board is a piece of crap. I have it up on eBay for sale. I am looking for either the GVP 68030 Combo or a Blizzard 68060 Combo board. I mainly need the extra 32-bit memory, not the faster processor, for 24-bit graphics. I am staying away from the 68040 processor. They are the worst of the 68000 Series processors.
-
@magnetic
I'm a scary cat so I wouldn't overclock a 060/50 to more then lets say 55-60Mhz but 66Mhz is still within sanity boundries. Clocking it to 70, 75 or even 80 as some report they've done will even with sufficient cooling be puching it and it deffinitly needs to be an MC060 not an XC060 CPU then. I do belive that some MK3 came with a 060/60Mhz CPU and then it's quite possible to clock it to 70-75Mhz but still more then that is pushing it.
-
@BoingBoss
Every time you get the chance you promote the old fart A2000 and no it's not the highest quality Amiga. About the 040 CPU I'm prepared to agree with you that it is the worst 68K CPU, though the not so common 3.3V version didn't run nearly as hot and much more stable than the 5V version of the CPU.

Hi BoingBoss
Are you experiencing any instability with your system at 28Mhz, or are you simply downclocking to 25Mhz just to stay within the stated rated speed of the chip?
Assuming you're not experiencing any stability issues, I'd say you'd be better off seeking out an '060 board as you suggest. That way you'll be able to play mp3 file etc without having to overclock a system in order to do so.
Assuming you are experiencing stability issues, it might not neccessarily be the hardware. You might want to try starting your system with no startup sequence, or commenting out some of the programs launched in the script to see if any one individual program is causing you problems.
Good luck!

Not if it is the military grade 68040 !
I never had any problems with my 68040-25 overclocked to 33 MHz.

@Mugo
Do you have any docs for your 040->060 upgrade? I've done a similar upgrade to my CSMK2 card as well as overclocking the 060 a bit. I've had the thing up to 72MHz, but it was somewhat flaky there. 70MHz seemed more stable, but I backed it down to 66MHz and all seems quite well.
If you have a web page describing how you upgraded your BPPC 040 to 060, I'd like to add a link to that from my CSMK2 upgrade page. Anyone else in seeing my page, which needs some of the text cut down to be easier to read through, it's at

YES, the Amiga 2000 is the highest quality Amiga. Commodore had lowered the quality, to make more profit, starting with the release of the Amiga 3000. I use to work for Commodore, so I should know. Brian, do your home work before talking crap!
Now for the 68040 processor. The XC68040 is the 5 volt version. The MC68040 is the 3.3 volt version and is very hard to find. I have been looking for one on eBay for months and have not been able to find one. All of the sellers only have the XC version for sale.
-
Doomy, care to explain us the things that make A2000 the "highest quality Amiga" ever? Plenty of detail, please.
-
Hi PMC,
Are you experiencing any instability with your system at 28Mhz, or are you simply downclocking to 25Mhz just to stay within the stated rated speed of the chip?
As always, my system works fine. I never experience any instability with any of my systems, because I know what I am doing when it comes to the hardware. Yes, I want to downclock to 25 MHz to stay within the processor's rated speed.
The problem I am having is that my Amiga 2500 will not "see" the memory on the Progressive 2000/040 board. SysInfo sees the 68040 processor just fine, but not the SIMMs. I am sure that I have the jumpers set correctly, but just in case, how should they be set? I need the extra memory because I am working with 24-bit graphics and the 8 megs on the Zorro II bus is not enough. I need at least 8 to 16 megs of 32-bit memory in order to use my GVP EGS 28/24 Spectrum video board to its fullest potential. :roll:

Again with incorrect facts.
The 3.3V 040s are the MC68040V (no-FPU) or MC680EC040V (no-MMU/FPU). The V designates the low power, all the other models are 5V, no matter if they are MC or XC. The V series chips are not pin compatible with standard 040s.
As for the one that said the 040 was the worst. Hindsight has probably proved that. But, at the time it was the best, and is still leagues ahead of the 020-030 chips in speed. (A 40MHz 040 is more than twice as fast as a 50MHz 030).

RTFM. :roll: What version of the software? What command line are you using to initialize the card? AFAIK, early versions required AddMem, but later ones have it built into the Init040 utility. Have you tried the MemTest program?

Hi Eco,
Doomy, care to explain us the things that make A2000 the "highest quality Amiga" ever? Plenty of detail, please.
All you have to do is take a good look at the way the Amiga 2000 Series computers are built and you will plainly see that they are the best built of all the Amiga models. Afterall, the Amiga 2000 was designed and made in Germany, so hence the higher quality. Let's start with the chassis. It is made out of very heavy gauge steal and is well designed. The "cross" on the bottom helps make the case more rigid. The German Amiga Team had decided to use 3mm and 4mm metric machine screws because there are more threads per inch, so less of a chance for stripped out screw holes. Next let's take a look at the Amiga 2000's power supply. It is "beefier" and much better made then the power supplies that are found in the other Amiga models. The cooling fan is made in Japan or Germany and is very high quality. The electronic parts in the Amiga 2000's power supply are also very high quality (just look at the heat sinks and caps). Now let's look at the Amiga 2000's motherboard. It was designed and made in Germany. It is the higher quality "thru-hole" design, not the lower quality "SMT" design (like the Amiga 600, 1200, 4000, 4000T and the AmigaOne piece of crap). All of the main chips are socketed for easy replacement or upgrades. The Zorro, CPU and video slots are on the motherboard, which is a better design. They are not on a daughter board, which is a poorer design (the Amiga 3000 and 4000 have their slots on a daughter board). This is the reason why I prefer the Amiga 3000 Tower, because its slots are on the motherboard, just like the Amiga 2000 computer. Also, the Amiga 3000 Tower has a very nice case and power supply, just like the Amiga 2000. I can go on and on as to why the Amiga 2000 computer is the highest quality and best built of all the Amiga models, but I think you already get the picture. :-D

Hi adolescent,
Again with incorrect facts.
No, I am correct. You yourself even stated that the "MC" version was the one with the lower voltage.
Not all of the 3.3 volt chips had a "v" at the end. MANY of them were misprinted and sold to companies like Progressive and GVP at a lower cost.
-
@Doomy
Lets see now... you claim that "thru-hole" design is higher quality than SMT... care to explain?
If by being big and heavy qualify for being higher quality then a tank is a higherquality car than a ferrari.
Exactly what makes a riserboard a poor quality?
Ever think about all the extra cooling in the A2000 was needed to keep it cool where in the newer Amigas this wasn't needed as better quality chips where used?
Oh and about the 040... you go do your homework. Lol coming and start defend your wrong statement by stating that some chips where marked wrong. So they where marked "wrong" just as you where wrong. Please have a look at the different MC040 (http://www.amiga-hardware.com/processors.html) versions and you'll see that the V is just what marks a 040 chip as a 3.3V version. All other MC/XC040 chips are 5V.
@adolescent
The MC68040V have FPU and MMU, the MC68EC040V doesn't.

@Gloomy
Made in Germany: How exactly does this make the product better? Zero argumentative value.
Rigid steel case with screws: A3000 and A4000 were rigid enough for my purposes, I don't think the A2000 had any advantage here. And I've seen some bombproof tower conversions in my time.
Power supply: what are the exact specifications; how much amps to each rail, as opposed to A500/A3000/A4000? Pardon me for not trusting your biased visual inspection.
Cooling fan: Japan/German made high quality fan? Is it double ball bearing? MTBF? As opposed to fans in other Amigas? What makes it special and worth mentioning?
Socketed design vs. surface mount: allows for replacement, but subject to oxidation of the socket/chip legs. And the A2000 is not the only Amiga with chips on sockets.
Zorro, video and CPU slots on motherboard: Why is this a better desing? It doesn't allow for easy replacement? And it makes the motherboard HUGE!
I am not convinced. :-)
-
Hi Eco,
Made in Germany: How exactly does this make the product better? Zero argumentative value.
As all smart people know, the countries that produce the highest quality stuff in the world are England, Germany, and Japan.
"argumentive"?! I am not arguing, I am just stating facts. :-)

I see you surtantly live by that. :roll:
-
@BoingBoss:
For the AmigaOS to see the memory installed on the PPS Progressive 2000/040 card, you both have to set the jumpers correctly plus have the software from the PPS040 Install-Disk (http://www.l8r.net/install/accel/PPS040.DMS) installed.
There is some info about this card on this (http://amiga.resource.cx/exp/search.pl?product=Progressive+2000%2F040&company=) page.
If you get the 32-bit memory working you should experience a big performance-boost compared to when using only 16-bit ZorroII-memory.
Good luck!

No, you are not correct (again). MC and XC have nothing to do with the chip voltage, period. I have a MC68040@40Mhz that is a 5V chip. All 3.3V 040s have the V designation. There is no way that GVP and Progressive used the 3.3V chips. They are not pin compatible, and are not interchangable. Plugging a 3.3V chip into a 5V socket would no doubt result in a puff of smoke and an unusable computer.

Doomy's wild storys continue... of cause as common sence will tell a 3.3V chip getting 5V would result in failure but not in Doomys world.

No, the MC68040V is a low voltage version of the MC68LC040, therefore lacks the FPU like the MC68LC040. From the user guide (sorry to jump around, but the guide is in a different order.)
APPENDIX C MC68040V AND MC68EC040V
For the MC68040V, all differences that exist between the MC68LC040 and the MC68040, as described in Appendix A MC68LC040, also apply to the MC68040V.
APPENDIX A MC68LC040
A.1 MC68LC040 DIFFERENCES
...
The MC68LC040 does not contain an FPU, which causes unimplemented floating-point exceptions to occur using a new eight-word stack frame format.

You are correct and I was just to post the findings I got from motorola.com (http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=MC68040&nodeId=018rH3YTLC4622)... I was simply missled by TBBoAH processor information. :oops:

No problem. I noticed they said it's 100% compatible there, whereas Motorola also say it's not pin compatible.

Dunno about the 2000 but on the 1200, some accelerator boards (like the Apollo) run *MORE* reliable at 28MHz, due
to better synchronization with the system bus, the CPU does
not have to wait all the time.

I'm sorry to be so rude as to interupt this semi-interesting

That's a thing that should not be.
VW never must break down.
That's why VW is selling much cars, because of the broadly accepted quality.
Perhaps they send the crap ones over to England and keep the better ones in Europe.
Or they refuled with diesel instead of petrol ;-)

Essentially, that would be overclocking the chipset, and AFAIK, the custom chipset doesn't like to be overclocked by more than few percent past default NTSC. (May also mess with video output, come to think of it?)
-
There was a thread on here many months ago about overclocking the chipset... come to think of it, I think it came out of a thread I started about using a pin-compatible 68010 as a drop-in replacement on an A600.
If I remember correctly, overclocking the chipset did not work, and there were severe video problems. Theoretically, if you could get it perfectly doubled, you might have a default 31KHz video output. (?)

I had a Progressive 040/500, and to use the extra RAM on that you needed to use a software tool to enable it. If I remember, I ended up using RomTagMem from aminet instead of the tool that was on the PP&S floppy disk, as RomTagMem allowed to configure the RAM and then immediately do a soft reboot, which would let the system get into that memory rather than be stuck in slower motherboard RAM for hte OS. RomTagMem wasn't super easy to use, and you'd need to use the Progressive program at least once to figure out hte address the on-board RAM starts at, btu it was great.

Yea. The A3000T I've seen was built like a tank too. But I understand there were two A2000 designs, one in Germany and one from USA. The German one using a single Zorro slot and some other differences, but perhaps they kept the German case design. Regardless, the case design, screw threads, etc. do not a high quality computer make, IMHO. I'm more of an electronics guy myself, give me a great motherboard in a crappy case and I'm reasonably happy with it... I much prefer using my A4000T (Quickpak style), A3000D, and AmigaOne to my ancient A2000T (self-built full tower) which now lives in my attic. The A2000 with 040/33, 8MB 32bit RAM (maxed), and Zorro2 just couldn't keep up with the software I want to use these days. ImageFX, which you might call "work", runs MUCH better on my 4000T than my 2000... Am I weird?

If I remember correctly, overclocking the chipset did not work, and there were severe video problems. Theoretically, if you could get it perfectly doubled, you might have a default 31KHz video output. (?)
You should be able to overclock the chipset somewhat... As I recall that's what a genlock does to sync up the video output. Isn't that why CPU clock frequency is seperate from the chipset in the first place?

I'm not sure if an Amiga genlock adjusts the Amiga's video timing, or adjusts the timing of the video after it leaves the Amiga. I always assumed it was the later, but perhaps I'm mistaken.
Anyhow, to run a CPU faster than 7mhz, the CPU frequency is seperated from the chipset/video/motherboard frequency.
Hmmm... if thats the case, wouldn't a Multi-Sync monitor solve that problem ??
I don't think so... Not unless you also have a set of new screenmode definition files (like the NTSC/PAL/DblPAL/Super72 files) that take into account the new pixel clock.
Otherwise I suspect you might get sync, but the display would probably still be garbled and framed wrong.

@BoingBoss
No you're not "messing" with ppl, you are insulting them and mock those who react. You got another chance from the ops to clean up your act and stay on but I see you've slided into your real self rather quickly and I guess it's just a matter of time before you're kicked out of the forum once more.

guys!!! don't wast your time with a dude that claims that "to play Quake is better than SEX" !!!
come on . . .he is copying&paste the same old story from the beginning!
EDIT- arghh . . . i'm fall back, in the Doomy trap again

But has anyone tried over-clocking the MoBo on any Amiga?
Yes. You know what happens? The syetem gets slower, much slower.
But you are getting warm:-)

Sounds like you're working on something interesting.
You gunna let us in on it soon ??

I wonder if Red's tinkering with bus / CPU clock synchronization?

I once overclocked my 1084S to get it to display a (slightly) flicker-free 640x400 with my A1200's standard, no-flicker-fixer-in-place video out.
It caused the monitor to dim somewhat (had to crank up the contrast) and I lost the bottom 4 lines on the screen - think PAL display on NTSC but not as much screen real-estate unviewable.
Hey, it worked! (And probably took years off of the monitor's life)
I think you can find the info on how to do it on aminet. Of course these days who needs to do all of that?!
-
@Red
So are you going to tell us what it is soon or not? Overclocked the Prom to 66Mhz PCI slots and hacked in a AGP slot?

Hi Framiga,
guys!!! don't wast your time with a dude that claims that "to play Quake is better than SEX" !!!
You really should learn how to read. My Doom II web site, in the Deathmatch area, states that "Doom 2 deathmatch is so much fun that sometimes I think it is better then SEX!". That area mentions nothing about Quake deathmatch. :roll:

@Doomy
I think, amongst people who have tried both, you will find a general consensus that "sometimes is better than sex" is not correct :-)
-
Well, if you're forced to have sex with someone who doesn't turn you on, computer games might be a lot better...
-
Hum,
and the `fun` doesn`t stop there...
Let me tell you of my unhappy `experience` with increasing clock speeds...
i once managed to create rift in the space-time continuum by overclocking my 2600 MHz Athlon at <snip - edited due to safety concerns> GHz.
Overclocking is generally understood by all to be a bad thing for the CPU and Motherboard (and it may even add to global warming), so you see, it is understandable that i haven't recreated the experiment again...
i guess that the CPU clock cycle was operating so fast that it began to execute instructions before they arrived. This execution of future instructions created a small tear in the fabric of space-time itself .
Luckily the Asrock motherboard was fitted with a COP chipset heat monitor that cut off the power supply, and also by virtue of going so fast being able to travel backwards in time, to just before the rift was created.
So, no embarrassing call to the insurance company...though i doubt that they would cover time- travel and cracks in space-time.
i did a quick `google (http://www.geocities.com/goarana669/overclocktime.html)` for similar results, but revealed nothing, but i suspect that this is not a one off case;
hum, very strange, (thought hesitate to cry government cover-up).
Anyway, i`ll leave you to draw your own conclusions...

I once turned down sex to watch Star Trek II... The young lady involved was NOT impressed... I wasn't even that interested in watching the film either (I'd seen it countless times before :-s )

May? MAY? Environment be-damned, I conducted my own, more controlled Athlon overclocking experiments a while back... During which time, a large block of ice broke from the polar ice-caps. Coincidence? I think not.
I started with a lowly 10% overclock, and my box started putting out more BTUs than my furnace. I was happy, though, because I found myself saving big on my winter heating bill. However, encoding DivX required me to open the windows of my apartment to avoid heat-stroke, even on sub-0 freezing winter nights. Kids couldn't build snowmen for blocks because everything thawed and trees started growing new leaves in December.
But, I figured that was safe enough, so I wanted to push things further. I raised the core voltage a few points and boosted it up above a 20% overclock. I found out I could cure pottery and sterilize medical equipment, simply by putting it inside my apartment! Now I was saving on my water bill, as well. Dirty dishes? Here, we can autoclave them clean!
Of course, due to the heat, I couldn't get close enough to the machine to try pushing it further. My next set of experiments involved cooling the thing with dry ice and pushing the core voltage up to 1.21 jigawatts. In hindsight, I suspect this configuration might also cause problems in space/time and perhaps even bad sequels, as well. It may be best that this series of experiments were never carried out. ;-)
These Athlons are clearly dangerous. We should start a class-action lawsuit before someone goes and destroys the universe, or something. :lol:

I'm not surprised she wasn't impressed! Was she THAT bad?
:-o
Couldn't you have done the decent thing as just gone out on the lash with your mates instead? She's have probably been able to deal with that one.
Actually, I know a guy who turned down sex to go mountain biking... Before you ask, no it wasn't me!
Just had an idea from a new thread....

hi I noticed something supicius about this, homepage, he has a "certificate" Top 25 pc games websites.
I am not a hardcore PC gamer, but i realy doubt this site http://home.comcast.net/~doom2fan/ qualify for this title.
I suspect it migt be made in MS Paint, but I dont know.
If he falsely claims this title it would, be nice to have the link for his PC gaming homepage removed from Amiga.org.
I made some quick, seach for Top pc games websites on google, to find out If this claim is correct or not.
Hope somebody, can find it easyer than I, if not I WILL take the time to find out.
This guy "BoingBoss" seams to have a quite a bad attitude.
