Overclocking on liquid nitrogen and pushing hardware into the danger zone can be very frustrating but can also be rewarding. We recently released an overclocking video that showed you how I prepare my motherboards to run on liquid nitrogen. I recently took the same setup from the video but with a different CPU, and tried to set the 3DMark03 world record with it.
After a weekend of testing I was able to secure third place in the benchmark with a score of 229,115 3DMarks. I knew I could push the CPU higher, so I made up my mind to try and take the world record poisition. After several more days of testing I was able to get the CPU clocked to 6.68GHz and get a run of 231,239 3DMarks. This was good enough for second place, and only a few thousand points behind first place.
I knew that I could easily get first place if I could just get a few more runs in with slightly higher CPU speed. Unfortunately, like I said earlier, pushing hardware to its absolute limits can be frustrating. After a five hour overclocking session, countless blue screens and crashes, the CPU finally had enough and no longer wanted to run 3DMark03. I tested the CPU one more time but it lost two of the memory channels so I was only able to run in single channel. I decided to run 3DMark05 this time, so I changed out the graphics cards to four 5870s. Again the CPU ran at 6.68GHz and I was able to get a result of 59,626 3DMarks. This was good enough for 6th place on HWBot.org.
Unfortunately I was unable to break the world record in 3DMark03, but with extreme overclocking that is the way it goes sometimes. I was still able to take a solid 2nd place, beating the previous 2nd place score by 2000 points. More details on the scores can be seen on HWBot.org 3DMark03 and 3DMark05.—
