5ghz+

Yeah that's pretty cool... but they'd get better results with an Athlon64 :-P

Back in the day, someone overclocked a Dec Alpha 262144 rated initially at 200MHz to 800MHz with cryogenic cooling. This was at a time when a P133 was 'state of the art' ;-)

I still chuckle to my self when I see post on this forum about overclocking thier 68k's by staggering amounts... like 5MHz... what's the point... :-D

5MHz is quite a respectible overclock if you are starting from a 25MHz clockspeed.

680x0 parts were typically rated close to their tested speeds, unlike most x86 parts of the same era that were rated much lower than their tested speeds, all in the name of long term reliability. Ironic considering the typical lifecycle of their descendents :lol:

:lol:

That said, Motorola engineers claimed to run the 68000 at 50Mhz...

Though judging by how hot the 8Mhz 68k in the A600 gets, I'd say they were using an HCMOS part or something...

I'll wait until next year when Intel and AMD legitimately break the 4ghz barrier, then 6 more months for the 5Ghz barrier.

Yeah, but surely there's no fun in that...

If you want fun crank up a 68030 to 5Ghz...  :-D

-Edit- That's only 100 times speed increase... now all you need is a memory subsystem that could cope :-/

As long as it doesnt melt, the ice isn't a problem. It's not particularly conductive (conductivity of water tends to rely mostly on ion transport which requires it to be liquid to be effective)...

Indeed, pure water being a very poor conductor... add a few ions though :-D

You can't beat a good 4M solution of hydroiodic acid for electrical conductivity :-D

One of my projects was to build a fuel cell.. I used 8M Potassium Hydroxide... heated to 80 degree C... that stuff was a pretty good conductor :-)

Let's see what diamond based semiconductor will allow before we totally write off the GHz contest...

Yeah, that stuff can take quite a bit of heating :-o

But I think that technology is a while off... Dual cores will take up the slack for the next few years...

Yes, that would be a good idea. However, the only x86 based solution that comes close to what you desire is the VIA Eden, plus they come in miniITX, just a thought.

Hey that VIA Eden chip does look great! If it has full MS software compatibility, that might just be my next computer. My P3-1GHz runs everything I have at a decent speed and that chip might even have better performance with it's SSE support.

Bear in mind that my 2Ghz Athlon64 3200+ runs at 26 degrees C... that a damn slight cooler than any 68k I've enver seen.

Honestly you'd be fine with an Athlon XP with a decent cooler on it (IE, not the stock one). I had one with a water cooler and even on the hottest of days the thing at full tilt never rose above 40C, even overclocked as much as it was (1.6Ghz stock up to 2.0Ghz).

My Athlon64 runs at 26 Degrees (over clocked!) with the stock cooler, the one that came with the "Processor in a box".

I think the best thing about the Athlon64 is not it's 64bit ness but it's integrated dual channel memory controler... the performance boost that they alone give is phenominal!

The readings I gave were from mbm5, I honestly can't see an Athlon64 running that cool, not with the stock cooler, especially given the Abit boards web boards. I don't know, perhaps the newer models do run cooler, but in my experience with AMD64's with the stock cooler, its simply not effective at cooling the thing. No amount of re-adjusting or putting on arctic silver instead of the pink goop thats on the thing as standard drops the temp. I dunno, perhaps I've got a duff one... But I will need a far more effective cooling solution if I want to keep this system beyond next year in a servicable condition.

I forgot to say that my Athlon64 is a 90nm SOI one (like all new Athlon64's), which run much cooler (and over clook much better) than the old 130nm chips.

The stock fan is really quiet too.
