what accelerators are cool enough for A1200?

[koshman]

You probably won't get over 60Mhz with the original 060 revision, but as amigakit says (I guess that's not a person's name, but... ) newer revisions such as the E41J will let you overclock more. E.g. my E41J Cyberstorm is clocked at 66Mhz, but it runs cooler than the original 060 at 50Mhz.

I am looking at getting a beefier card than my 030/25, but I am concerned about heat.
Reading a bit, it seems that 040 and 060 cards will cause heat issues in a normal A1200 case, is this correct?
 
What about an 030/50 ?
 
Basically, whats the beefiest option for a non-towered plain old A1200 case ?

A 68030 50mhz will be fine, I'm running mine with 64 meg of ram and a 2 gig compact flash in a 19" rack.  No issues at all!

Thanks for all the help guys

The question was not for me, but I'll chime in anyway - Breathless is still slow on 030/50 to play on the best settings in my opinion, as is Doom (at least ADoom, that is, haven't tried Doom Attack, but it should be better optimized). Playable, but still far from smooth. I'd say Breathless is not smooth even on 060, but I don't like the game much anyway - it's like AGA = 256 shades of gray...

Edit: as for other FPSs - AB3D totally smooth, AB3DII totally not smooth bordering on unplayable, of course; Genetic Species pretty fast, the engine is well optimized. My general opinion is that 030/50 is not fast enough for decent 3D games, but most of them can be run at playable speed at least.

ah, too bad about Breathless.
Figured AB3DII wouldn't run, supposedly this barely runs on an 060.

I can currently run Gloom and Fears pretty smoothly, so if an 030/50 would let me play full screen, I'll be happy.

I'd have to check out Genetic Species. I havent installed it currently, as Im pretty sure it wouldn't work well with 8 meg fast only

I would also recommend Nemac IV, which is highly underrated in my opinion and runs great on 030/50.

I actually have this installed. The intro is awesome.

It runs okayish on my 25, so I imagine it'd do great on a bigger card

there are some very very fast cards out there if done correctly this game should work..

some users have 68060 running @70Mhz+,their say appollo 68060 @80Mhz cards runs faster than Blizzard PPC card.

i think it about time to find out if this is true Blizzard PPC 68060@83Mhz.

Hi, I thought you may be able to answer this... I saw all your work on overclocking the Bliz. PPC cards, very impressive stuff! :-)

I have a Blizzard (Phase 5 rev. 1) 1260... wondered if I can overclock it to 66mhz and still keep it in the desktop case (without fan)?

Or do I need to tower my Amiga if I want to overclock the 060?

Also, can I use this 66mhz crystal from AmigaKit (http://amigakit.leamancomputing.com/catalog/product_info.php?cPath=45&products_id=167), and is their instructions on how to do it anywhere? (Any soldering required?)

Thanks, Alex.

it depends on what mask the 68060 is. if its mask 71e41j the processor will run cooler than other revision. ie no fan needed.

all 68060 should overclock to 66Mhz

the osc from amigakit will work.

RECOMMENDED: get a expert to desolder the old osc. don`t try it yourself unless you have very good soldering skills.

**all modification at your own risk**

[jsixis]

I would get the 060 it runs way cooler and you will have fewer problems with software.
I have an 040 in my 1200 and I wish I would have stayed with the 030.

[rkauer]

Thing is: the 060 will break some WHDLoad games (like 10~15% of them), and 030 will be compatible with all.

 060 is awesome for ultimate AGA games and towered A1200 with a Mediator and a graphics card.

 If you have another Amiga to run the flawed games that the 060 can't run, then go for it. Otherwise grab the best 030 accelerator you can buy, which is the Blizzard 1230 mk4 overclocked to 60MHz (you need to add at least a heatsink over the CPU & FPU & modify the trapdoor).

 Now the Apollo 1260 can run a 060 at 80MHz when using the latest 060 mask CPU (71E41J) and will beat the Blizzard 1260 @66MHz.

Except my earlier revision mask 68060. It's max STABLE operating speed was 60Mhz. Now that i have the latest mask i can easily put on a 66Mhz osc. But i still use 60Mhz to be sure .

71E41J can actually go to 100Mhz (and beyond)....just ask the Atari guys

The problem is that the accelerator cards (memory timing) cannot keep up with them.

i don`t know what revision you have,but i have a few old revisions and every single one overclock`s to 70Mhz or even 72Mhz.

i also have MC68060RC66E which i use for testing. but don`t be fooled by the marking,as what`s mark on the outside is not always whats on the inside.  

every now and then i drop in a old revision as some my E41J 68060 has problems or maybe a fault with some of my processors.

look out for the marking on the left hand side of the processor ( E41J ) mine has S23328 004 and some end with 006,but some ( E41J ) end with 002.

i think 68060 has been clocked as high as 120-125Mhz,but here on my Blizzard PPC it has been clocked as high as 86Mhz.


marking also appliy`s to simms

the fastest EDO is 50ns,but don`t be fooled by the markings. there are some very poor 50ns simms out there.

there are some simms marked 60ns that out perform even simms that are marked
50ns so beware.

poor 50ns simms =47ns
good 50ns simms=45ns
very good 50ns simms=43ns
super excellent 50ns simms=?

very good=80mhz bus speed on Blizzard PPC card
Super excellent=83Mhz bus speed and above on Blizzard PPC card

this is why my Blizzard PPC card is as fast as a Cyberstorm 200Mhz and getting faster.


2nd fastest Blizzard card in the world.


68060@70Mhz 603e@320mhz ( 80Mhz bus ) with SCSI - 35Mhz PCI bus

ram settings all turned off in Blizzard menu ( DO NOT TRY THIS ON A VERY FAST CARDS WITHOUT **SPECIAL** PROPER COOLING ). you will damage the card.

[stefcep2]

The Apollo cards have a very fast memory bus, faster than the phase 5 cards.  In fact back in the day AIBB memory speed benchmark of my Apollo 68040 was quicker than a PPC/68060 board we had at the local user group, when by all accounts it should not have been.  

Apollo boards also have a blizkick-type utility call remApollo (on Aminet), and this lets you map the OS ROMS and other things like ftext and fblit into the fast ram.  It makes a huge difference in operating speed.  But get an '060 if you can.

 TBH I haven't experienced any whdload games that didn't work with it since I upgraded my 68040 Apollo to an 68060.
