I recently replaced my AGP NVIDIA GeForce 7600GT 512M with a newer AGP NVIDIA GeForce 7600GT 512M. I believe that the GPU processors are the same but noticed when changing over the heat sinks that the memory chips are of the Samsung variety (the old one had Nanya). The older card had a pre-windows boot BIOS, where as the new one needed me to install new drivers from the Nvidia site (using automatic driver scan) does not BIOS boot. My issue is that the Windows reported a BSOD on first reboot after the new driver installation (stable since and have since increased the voltage by 0.1V to the card spec, without BSOD) and there is no solution in the Action center, and Windows is still looking a month out!? Upon opening the Nvidia control panel suite to check why the newer card did not have any on board memory to aid Adobe rendering (as the last card did use the 512M vram), I found that the suite reports the card as a GeForce 7600 GS...could this lead to a driver "signing" conflict and therefore the BSOD? Computer Management reports the card as the GeForce 7600GT as does the device properties driver tab... Would it be possible to flash the BIOS on the newer card so that the 512M of vram is "scalable" for Adobe rendering use? Thank you for reading.
