Hello everyone. I have myself a Geforce Go 7900 GS, and I just recently installed the 174.74 drivers. I have been previously using 169.04 drivers, because for every driver released since then, I am unable to overclock my card! I have tried many different tools, including nTune, atitool, and rivatuner, but all with the same result. When I try to overclock the card, even 1mhz, the test immediately fails and puts it back to its default speed. This has been rather frustrating me, and I hope someone can help me out here. Thanks in advance!
