Ultimate Cooling System
OCGeek writes "This should be interesting for the overclockers as
VR-Zone has an article up on building a
cascade cooling system that
cools chips down to -110C. The guide shows you the components that are required
for the cascade cooling system such as the compressors, condensers,
refrigerants, evaporators, heat exchangers, oil separators etc. and the tools
you would need. It allows hot chip like Prescott to reach over 5.1Ghz and ATi
Radeon 9800 XT card to reach over 660Mhz core."
This seems a little complex and extreme for the home builder. Maybe a specialty co-lo opportunity, though? "Icebox netbox"? No good for gamers, of course. But for others who need MIPS for problems that can't be parallelized...
Everybody's a libertarian 'till their neighbour's becomes a crack house.
I've always wondered this but nobody's ever given a satisfactory answer to "why not".
Why not overclock network cards as well as CPU and graphics cards?
think about it
If I can get 10mg from a normal network card and overclock it for say 15 even if I need shorter cables, that's only shorter than maximum isn't it? So instead of 30ft cables I might be limited to 20ft. Big deal in a home network, NOT. I could overclock some more of my machines and have them all going at 15mg, and get better network speeds. I'm surprised there have not been articles about this. Or what about modems? or monitors? or even sound cards to get higher frequencies and better bass from them?
Why stop with just a cpu when it's not even a slowest part of a system but hard drives might be more difficult
I hate lazy people.

These techniques seem like brute force schemes to deal with the thermal resistance of chip packages -- you have to cool the heatsink to -110C in order to keep the "intel inside" at less than +60C). Why not use backside thinning. to bring the hot circuits of the processor within microns of a high coolant flux chamber. Backside thinning could get the coolant to within 10 microns of the junctions. If the CCD people can thin a massive 2k x 2k CCDs (the die is bigger than 1" square), I'm sure an enterprising overclocker could thin a Pentium.
Two wrongs don't make a right, but three lefts do.
This has me thinking. Sometimes I do that =)
:)
But seriously. Anyone seen sites with info on overclocking ancient CPUs? I remember once seeing a 486 overclocked well over 100MHz, perhaps into the 200MHz range, through refrigerated cooling. To me, that's as interesting as getting 5GHz from a brand new CPU.
Any 50MHz 68000s? A 300MHz Pentium I? 250MHz from a PPC601?
A 50MHz Commodore 64, even?
Now this is the ultimate cooling system... =)
The last part of the video (the flower thing) is even scary!
They say that Intel is still manufacturing 386 processors for those who want them, but using a much smaller scale (perhaps 0.2 micron or whatever) because that's the only fabs they have nowadays. These small-scale 386es sound like they'd be easily overclockable. Similarly, someone posted on Slashdot recently about Overclocking the Genesis / Mega Drive because later models have a better m68k CPU than needed.

Early in the 3D hardware days, you could use two cards to double performance. One card did the even scan lines and the other card did the odd scan lines. Not sure if this was possible with all games but it certainly was with Descent and/or Descent II.
With all the hubub about video performance these days, I wonder why it's not still done today. Probably had scalibility factors...?
DRM 'manages access' in the same way that a prison 'manages freedom'
Yes. The original poster saying 30fps is the maximum is mostly correct, in that gamers who say they can tell 300fps from 250fps are full of crap.
However you're more correct in the specifics, in that the limits of what a human can notice with respect to frames per second is more along the lines of 60-90fps. Almost all humans with sight can notice the difference in smoothness, some a little higher some lower.
If you get the chance watch a movie recorded in 60fps, played back on machinery that can handle it. It's a truly disorienting experience as you DO notice a much greater level of smoothness and there's less motion blur in even fast switches, which is more akin to that of eyesight experiencing a real event. I had the chance to see this while at University several years ago.

Yes, but don't forget about condensation. You need some sort of super-dehumidifier, or a solution such as that used by Tom's Hardware several months ago (when they booted a P4 to 5ghz). Too lazy to link/whore karma.

Intel calls them mature processors, and they are now sold to the embedded market. You can still buy a 486, a 386, or even a 186.
