NVIDIA GeForce 9800 GTX Extreme Overclocking Experiment

Thu 2008-05-15 - Posted by Patrick "MACMAC" MacMillan

MadShrimps has posted another Extreme Overclocking Experiment, in which they combine an XFX GeForce 9800GTX with liquid nitrogen (LN2) to achieve some amazing overclocking results.

Here’s an excerpt:

“The maximum stable overclock on the GPU was an impressive 1053Mhz ; you know that the reference clock speed of the GPU is 675Mhz; thus we saw a 56% increase! The GDDR3 memory could be OCed only ~17%. Last but not least with the release of the latest Rivatuner we can separately clock the GPU and Shader clocks and this certainly pass of; default at 1688Mhz we got it up to 2658Mhz! (+57%!)

For comparison, the maximum OC with air cooling was 805/1235/1944; nowhere near as high as the LN² cooled results!”

This card reached some extremely impressive speeds, despite the fact that the core was limited by a coldbug at -45°C. If NVIDIA can successfully release a quick fix, I wouldn’t be surprised to see a slew of new records set in the single and triple GPU categories.
