Overclocking:

With NVIDIA Linux CoolBits loaded, and Thunderbird's LH.o NVClock v0.8 BETA being used for reference purposes, we set out to overclock the eVGA 6800GT 256MB PCI-E. Cooling is always important to keep in mind, and with our setup we recorded the GPU to be in the low 50's (Celsius) while idling and then in the low 60's under intensive benchmarking. To start off, we used the auto detect feature built into CoolBits. Going from the stock 350/1000MHz speeds (GPU/MEM) the automatic detection feature automatically scaled the 3D clock frequencies up to 414/1122. After we had tested the graphics cards at these speeds to ensure it was stable and free of any artifacts or overheating, we proceeded to increase the two clocks in 1MHz increments until we had reached the breaking point. After some tweaking, we had managed to get the NVIDIA 6800GT running at 420/1130, or rather 420MHz for the 6800GT GPU and 1.13GHz for the video memory. While at these speeds, the GPU was fluctuating between the upper 80's and low 90's (°C) while under intensive load so we had backed off the GPU to 415MHz while reducing the memory to 1125MHz. At these overclocked speeds, we experienced no problems in regards to artifacts, overheating, or stability problems. From its 350/1000MHz stock settings, we were quite pleased reaching 415/1125 on stock cooling considering that the stock speeds for a 6800 Ultra reference clock speed are 400/1100.
