Overclocking and Temperature

Our attempt to overclock the Albatron 8800GTS-512X proved to be quite successful. The graphics core was stable at frequencies of 760MHz (main domain) and 1875MHz (shader domain). The first number is the same frequency as we achieved when overclocking such cards as XFX GeForce 8800 GTS 512MB XXX Alpha Dog Edition and Leadtek WinFast PX8800 GTS 512MB, but the shader domain frequency is somewhat lower. We don’t think it is going to have a serious effect on the card’s performance, though.

The GPU temperature remained at 43-58°C in 2D mode and reached 85°C under 3D load. These are normal values for a GeForce 8800 GTS 512MB although a small increase in the fan speed would be appropriate. It would help reduce the peak temperature without increasing the noise much.

The memory chips overclocked better than on the cards we had tested earlier. It worked at 1120 (2240) MHz but we reduced the frequency to 1100 (2200) MHz to achieve full stability. The memory frequency growth is considerable, so we will test the card at the overclocked frequencies to see if the GeForce 8800 GTX has any chance against an overclocked GeForce 8800 GTS 512MB.

Like all other versions of Nvidia GeForce 8800 GTS 512MB we had tested before, the Albatron 8800GTS-512X started up on every PCI Express 1.0a mainboard we tried it with, so it seems to be free from the compatibility issues peculiar to early batches of Nvidia GeForce 8800 GT 512MB.
