i got a 8800GTS from PNY with:
Stock Core clock 500-MHz
Stock Shader clock 1200-MHz
Stock Mem clock 800-MHz (1.6-GHz Effective)

i have mine OverClocked to:
Core Clock 675-MHz (170-MHz increase) 32%
Shader Clock 1570-MHz (370MHz increase) 32%
Mem Clock 1025-MHz (2.05GHz Effective) {225-MHz/450MHz Effective} 30%

i have the NGO 2.9792 drivers and Riva Tuner 2.0 Final release.

The Temperature has only gone to around 56C and never over 60C (fans always at 100%)
stays around 48C when in windows (the speeds jump down to 2D levels

i have tested these overnight with a free video stability tester i found online and have had no artifacts so far

are these changes too aggressive, will they destroy my card, or is this card amazing at overclocking?

anyone with info would be so kind as to share it with me, please?

Most interesting. Lets see some 3DMark2006 before vs after scores!

i had to reduce the Core Clock to 650MHz (the Shader Clock was reduced to 1515 MHz as well) to get 3DMark06 to run.
The Mem Clock stayed the same

Before OverClocking

Main Test Results

3DMark Score 7504 3DMarks
SM 2.0 Score 3487 Marks
SM 3.0 Score 3556 Marks
CPU Score 1635 Marks

After OverClocking

Main Test Results

3DMark Score 7906 3DMarks
SM 2.0 Score 3564 Marks
SM 3.0 Score 4007 Marks
CPU Score 1636 Marks

Difference (post - before)
3DMark Score 402 3DMarks
SM 2.0 Score 77 Marks
SM 3.0 Score 451 Marks
CPU Score 1 Mark

nice overclocking

RingWraith

The best way to ensure stability and stress your card to the max is to run the program below for at least a few hours. If you can do this and keep your temp below 70c then you have nothing to worry about.

thanks for the APP RingWraith, i will now always use it to stress test all my video cards

i had it running for three hours, and my card never went over 63C.

it looks cool too, would be a very sweet screen saver

how much louder is it having the fan at 100%?

And yes that IS an amazing overclock considering how cool it is running! Kudos

Very handy util that one that uses HDR/bloom rendering, can allow on the fly changing of the card as it dont run off to fullscreen mode.
