5ghz+

[Karlos]

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' ;-)

@bloodline

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:

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

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)...

[Karlos]

You can't beat a good 4M solution of hydroiodic acid for electrical conductivity :-D (For a water based conductor, I mean)

[Karlos]

Yeah.. buh, well, you have to make sacrifices to be the first to pass the 5GHz barrier :lol:

Come on, what's electrocution, picking bits of silicon shrapnel out of your face, 3rd degree burns and near death by asphyxiation from combatting the ensuing fire with the remaining dewar of liquid nitrogen suffered in the quest for another willy notch in the MHz scale?

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

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.

And how about without active cooling?

My 68040 + heatsink (unfanned) under 100% load never gets above 35C, and that is supposedly the hottest of the 680x0 series.

@bjjones37

Don't use degrees Farenheit man, its just too... wrong :-D

Embrace degrees Celcius (or better yet Kelvin) and never know fear again :lol:

@Waccon

I added the heatsink myself, thinking it would be needed. Frankly it isn't.
