Just screwing around and I had some 1/16th copper capillary tubing and some old air conditioning equipment so I coated the accelerator with poly all except for the cpu and wound a coil and used a mound of heat sink compund and mashed it to the cpu, fashioned a crystal and an adaptor from an old x86 and put it on board, then I placed the orifice about 3 inches from the coil, I ran the out put to a second coil (an ac condensor and hooked up the input side , charged the system with r-12 (yeah I still have a 30 lb can) and turned on the cooler. The evap coil I made froze almost instantly and so did the 68030 heh.
The monkey hits the switch and it comes on but there are some problems, my mouse moves way too fast, I can't seem to figure how this happened any ideas?
Second I can't get any games to work at all, all I can make work is imagine and it rednders lightning fast but forget modeling anything hah!
If anyone knows how to clock the board up right lemme know.

Umm.. Have you been eating funny mushrooms? :lol:

Shoot the T-1000 before it's too late!

NICE!
do you have any pictures of it ???
-
So you're using 133MHz 68030 (166% overclock from 50MHz), implying a 133MHz FSB speed (unless you completely modified the board to cope with that) with ordinary 60ns SIMMs and you can get it to boot? I find that pretty hard to believe to be honest ;-)
Even if you aren't pulling our legs, it would still only be as fast (in code execution terms) as a good 33MHz 68040 board.
-
Thats such a load of crap.

Memory chips wouldn't work, and the mouse would be unaffected by Processor speed increase.
I'll give you a C-, "Must try harder".

{bleep}ing hell some people talk sh*t, this one can go on the pile of myths about A500s running a 68000 at 100Mhz etc etc...

@lorddef
Don't you have a 60MHz 68030? It's only another 73MHz on top :lol:

What's going on in this room, there is too much blue smoke.. :-D

It might not that unbelievable if he was talking about an 040, they require an oscillator at twice the cpu clock frequency.
Even so i've never heard of anyone running a 66.5 Mhz 040
If anyone can remember fraggle from #gas, circa 1999, he had his apollo 040 40Mhz clocked up to 55Mhz with an 110mhz oscillator from onspec, but never got any faster than that.

I do remember reading that Motorola engineers used to run the 68000 at 50Mhz (and HCMOS I presume). Though AFAIK the 68000 was never comercially used at that speed... I guess the 030 was avaiable and more powerful by the time they could get a 68000 at that speed.

It's not so dense yet that you can't still see the red herring though :lol:
-
Nice story. A 030/133MHz would just barely outperform an 040/40Mhz and not even touch an 060/50MHz. Now, an 060 at 100MHz with liquid cooling would be something to see.
-
If it was a Deringer cards (that only supply half the crystal clock to the CPU) I could be made to belive you where able to run the 030 at 66Mhz but for running it at 133Mhz and only applying extra cooling on the other bobs and bits on the card I say it's a fairytail.
-
oh boy...funny {bleep} this one :-)
-
Who cares about a 030?? I'm sitting here running Os4 Beta on a PegasosIII G5 prototype right now :-o
-
double post, sorry.. but I'm so excited :lol:
-
G5? Sheesh, I have a G7. It's so fast it processes infinite loops in nanoseconds.
-
AAACHHHHHHOOOOOOOOOOOOO, Ohhh sorry folks I am allergic to bullss***
Actualy I have a ZX81 and I use the Z80 and this is attached on top of my 030 in such a way as I use instead of 40Mhz I now get the TRUE speed of 500Mhz. Bye the way I use a rock crystal from the local salt mine and a lump of white coal as a heat exchanger for better results.
Honest I do.

I have an intel 4044 4-bit driven calculator clocked to 7.6 GHz so nerrr :-P
-
Bah that's nothing I overclocked my 2000's accelerator 040 to '166MHZ' using an old Pentium crystal. I can't use the ram on the board though, have to stick with an 8meg on the Zorro slot, that and a DKB megachip, which sucks cause then other stuff with RAM (like my Retina) won't run with the other 8megs installed.
But my Screamer board prototype from Newtek here outperforms it by a good margin.
-
I *had* and 030 at 60Mhz, and that was on a blizzard without a scsi kit, never tried the scsi kit but I got the impression it'd be flakey at that speed trying one. The 030 its self never seemed hot, neither did anything else on the board but I knew it was pushing it.
Sold it on ebay, some lucky sod has that card now and I'm left looking for a big box.

Hi All,
Did once fit a 12Mhz 68000 in my old A500,
then rigged up a logic cct to double the clock
feed to the CPU 14Mhz ish.
The miggy ran fine , exactly twice as fast
but would not talk to the A590 (invalidated the disk)
but could format floppies at 880K *2, the standard
floppies were recognised as NDOS. :-D
-
Wasn't there a 'proper' hack to do that, but using an 010?
Anyway, there is a way to get an 030 to read as 133MHz - run a benchmark under UAE ;-)
-
Ok see I was just screwing around with this thing for kicks, I didn't really expect it to work but it was a 266Mhz oscillator and it still boots but everything is all fragged up because everythings outta sync. The major point of the entire discussion is anyone could box this refridgeration system up for probably $100 in parts and assembly, and develop a 68k accelerator to handle the speed, the only problem is dealing with the condensation. This little creature sitting on my workbench is a late night I couldn't sleep and had nothing better to do than tinker with something I knew little about just to see what happens, and the important thing is, the 030 didn't fry . If there is an actual person in this forum that knows how to clock the whole accelerator at a decent speed, maybe we can work this out.

One needs to be able to joke about himself. I'm sure meers could, and I have nothing against meers.
Light hearted joke. :)

266MHz my *rse. OK, the 030 doesn't generate that much heat but 50->133MHz with cryogenic cooling may be possible. As long as he temerature gradient is steep enough, you can siphon the heat away.
However, the memory on the card is driven at the same FSB as the CPU. Since you aren't cooling those and tbey aren't likely to be the 3.3v kind that were used in the last PC's to actually use SIMMs I strongly doubt your claim that the system boots.
People have tried to clock 66MHz 68060 cards with liquid cooling to 80MHz, the heat generated is not that great (probably less at 50MHz than the full 68030 is). However, the physical limitation on these overclocking has almost always been down to memory speed. None of the existing amiga accelerators have been designed to support such high FSB. Even the PPC cards use a 50/60/66MHz FSB and they took some effort to design.
No "I supercooled my cpu and ran it at stupid-MHz overclock" is going to change the fact that the other subsystems of the card cannot cope.
If you wanted to get a 680x0 >100MHz, you'd want a latest mask 68060 + SDRAM memory and a suitable memory controller designed for 100MHz+ FSB operation, as is found on the CT60 card for atari falcon for instance.
Nothing on the amiga motherboard is remotely affected by an accelerators local clockspeed, so your claims that the mouse is too fast etc. are completely untenable.
But do keep it up, it's entertaining :-D

Did I tell you about the time that I managed to get my Coleco to run at 3GHz? I had to switch it off before it became self-aware though. It had already deduced the existence of income tax and rice pudding before I had even connected the game controllers.

But had it figured out if it was best to top it with strawberry or raspberry jam ??
And if it had decided on neither and chosen golden syrup, then turn it off ASAP and destroy it, it`s a sure sign of an evil self aware computer, hellbent on world domination.
-
So thats where Bill Gates came from ...
-
Yes. It's well documented that Bill Gates was spawned by fertilizing primed rice pudding with a fusion of straberry/rasberry jam under the strict control of a sentient 3GHz coleco system.
Surely everybody knows that....
-
133 MHz I don't know, but something like 80 .. 100 MHz bus clock speed could be possible e.g. with a blizzard board.

Why waste your time with some old accelerator? You should directly contact AmiDelf, IIRC he is designing the Amiga6000 :-o

gREETZ,
If you wanna see some 68k proccS really overclocked,
go to http://perso.wanadoo.fr/didierm/
They got some nice pictures too.
It is Atari Falcon machine, not Amiga, but anyway, benchmarks has some real nice results ...

I think we should leave the orginator of this thread alone,
I once sprayed my nintendo game watch in liquid nitrogen and stored it a liquid nitrogen container, I then manged to boot the cpu to 10GHZ, yes 10ghz, the watch ran too fast though, and the buttons didnt work, but i soon had it contrloing everyhting in the house, until if fell in love with my missus and tried killing me and my family

Did it have Pierce Brosnan's voice by any chance???
-
Not sure if this accounts for anything, but some website managed to run a 33mhz 486 running around 150+MHZ??
I cant remember the website link, but they did pull it off. And please correct me if im wrong. :-)
-
It might have, but i think it might have had a donkey kong voice, that episode of the simpsons, one of the tree house of horror ones, is based on a film, but I cant for the life of me remeber what that film is called, anyone help

lol, you see, i don't think watches have misc processors :-D
but, then again, who knows. i did once carve an amd 64-bit processor out of solid oxygen :-)

These guys (http://totl.net/Eunuch/Eunuch7.html) managed to get a 25Mhz 486 SX running at 247Mhz, for all of 2 and a half minutes. Using beer and gin as a coolant.
-
Only miggy mods I did, was PPC boards and stuff for A1200. As for A500, I had a friend (who worked for an electronics firm) bring me a pair of 68010's, and excited about the prospect of making my Amiga more potent, I slapped one in. The machine worked fine (REALLY easy to swap the CPU). However, some games were not compatible, and I really couldn't tell what had become any better for having the chip in their, except that in my head it was faster, merely because the CPU said 68010 instead of 68000.
In my experience, unless you use peltiers or water cooling or a combination, it's not wise to overclock stuff much past 30 percent of it's intended speed. There are a few exceptions though, try using an AMD mobile Barton XP2500 in a desktop system. The multiplier is not locked, and the multiplier can be increased significantly without much extra heat generated.
That said, my system case still has a total of 9 fans in it, and I'd be unwilling to change the multiplier without the airflow I have.
So in answer to the question, no, I don't know how to make a 133Mhz 030 stable. I'm calling BS on this one like everyone else. :lol:

I don't really believe these claims, or at least that they ran Quake and half life on the system, simply because these games require an FPU, which the 486SX does not have.
-
Yes but they hacked the sourcecode of aforementioned games.
