serious overclocking!?

Question

apart from luquid nitrogen,which im having a problem with purchasing,what is another way(except using a cpu fan ) of keeping a cpu cool so i can push the clock speed higher
i am using a old athlon 2200(1.2ghz) and i want to see how much i can push this,every time i go even 5% higher with just the fan and heatsink it will crash and i have to reset the cmos
i have even considered designing a custom build,attaching the mobo inside a mini fridge and using a mate of mine who is a welder ,build compartments for dvd-rom and hard drive
the only problems being how to stop parts freezing too much and keeping the fridge at a stable tempeture
i will try anything,i am known by my mates as a serious headcase when it comes to stuff like this,i wonder why thats why they look worried when i approach their p.c,s
any ideas guys?
cheers

Answer 1

I have a Athlon 2200 which is 1.8GHz true speed I have mine running PC2100 ram and over clocked to (13.5*133) by default and I am running it @ 21.5*133 or 2.85GHz and and it's stable with fan only and runs around 101F...at the most or 38.5C..if it clips off @ 1.2GHz then the CPU is probably going out or the mobo...

Athlon XP 2200+ Overclocking
The most interesting part of reviewing a new processor core (especially one that is also a die shrink) is finding out exactly how much overclocking headroom it has. In terms of overclocking options, the Athlon XP Thoroughbred is virtually identical to previous models. The infamous L2 bridges are alive and well, and although our review chips came without the laser marks, we chose to go the FSB route to match what a retail buyer would experience. The option still exists to link the bridges, but using a 1 MHz FSB increment also helps us get a better idea on its high-end overclocking potential.

On the surface, the 0.13-micron Thoroughbred would seem to have a lot of overclocking potential, but the actual results were a bit disappointing. If you're thinking of buying the Athlon XP 2200+ for overclocking purposes, then stop right where you are. The highest reliable core speed we could get was 1931 MHz using a 143 MHz FSB and a core voltage of 1.775V. You may be looking at the core voltage and wondering why we didn't use 1.8V or higher, and that would illustrate the main problem we had when overclocking.

All overclocking exercises are a give and take between core speed, voltage and overall heat levels and stability. The Athlon XP Thoroughbred took this to a whole new plane, as even slight voltage increases would ramp up core heat quite noticeably (like you had crossed a line in the sand), while lowering the overall overclock speed. Finding a happy medium is a tedious and extremely long-term process, and even hitting over 1.9 GHz took a whole lot of tweaking. For all testing we used a Vantec copper HSF, a 7000 RPM fan and Arctic Silver 3, and it was still tough going at some points.

A by-product of the newer, smaller core is that there is simply less core real estate to work with, thus less coverage using a heatsink. This isn't really a concern with the Pentium 4, as Intel's S478 heat-spreader is the same size regardless of the actual die. We had some questions regarding this and apparently this is one of the reasons why the thermal requirements remain very similar for the higher-end Athlon XP Thoroughbred models. The lower-speed Athlon XP 1700+ (1.5V) is a nice improvement over the Athlon XP Palomino, but once we hit the Athlon XP 2200+ and its 1.65V requirement, the thermal specs start getting a lot closer to the Palomino.

There are improvements with the Thoroughbred, but don't go in thinking of a super cool-running processor, as you will need a heavy-duty HSF and any further voltage increases for overclocking will drive the heat higher. These results got us concerned about the overall viability of the AMD 0.13-micron core, and exactly how the company expects to move above the 1.8 GHz level for upcoming models. We had the same questions regarding the Duron 1 GHz, and as in that case, we are pretty sure a new Thoroughbred core revision is in the works that'll allow higher speeds.

Answer 3

There was an experiment online with cooking oil as it doesn't conduct electricity. Only problem with this is that you need to make sure the HDD is fully air tight. It had proven that a 3Ghz CPU ran at 5.3Ghz consistantly for over 24 hours until they switched it off. Although you will need a big fish tank.

Answer 4

Hard to believe you mentioned all that and didn't mention water cooling.

There are some pretty awesome setups out there.

Below is a link to a favorite site:

you can find kits at tigerdirect.com and you can narrow a search down with my fav www.pricewatch.com

Happy overclocking!!!

Answer 5

Have you looked into water cooling? You can find water cooling parts everywhere now, where computer parts are sold. Try newegg, or zipzoomfly, or http://www.frozencpu.com/

Answer 6

There are air conditioned cases available. Liquid cooling systems are also an option.

Answer 7

There are water-cooled cases around somewhere - rather you than me! Good luck, anyway. (I'D look worried if you approached my pc!) Fascinated to know if it works.
