Overclocking to 575MHz!

Overclocking Results:
Stock Overclocked
GPU (Core) Speed: 500 MHz 575 MHz
Memory Speed: 1400 MHz 1527 MHz
If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard

The MSI NX7900GT-VT2D256E-HD videocard comes pre-overclocked from the factory. According to MSI the core is clocked at 500 MHz while the memory hums along at 1530 MHz. The unit we received for testing had its core operating at 500 MHz while the memory was only running at 1400 MHz.

At 500 MHz the core speed is already 50 MHz faster than stock GeForce 7900GT GPU does. In any case we started our overclocking from this mark slowly increased the speeds in 5-10 MHz intervals. The GeForce 7900GT core easily cracked the 550 MHz mark and we continued to push the card further.

Just as quickly as it began, the MSI NX7900GT core topped out at a maximum overclocked speed of 575 MHz, which is a pretty quick for a GeForce 7900GT. A couple higher settings were tried, but they just caused the videocard to lock up when running 3D benchmarks.

Next up was the 256MB of Samsung GDDR3 BGA memory, and it is clocked at 1400 MHz by default (although MSI documentation boasts a 1530MHz clock speed). The clock speed of the memory was overclocked in 10-20 MHz intervals.

Inexperienced overclockers should increase the clock speed at a slower rate unless you want doom to strike at the very heart of your computer... muahahaha.

The Samsung GDDR3 memory easily passed the 1500 MHz point before settling on a speed of 1527 MHz. Anything higher than that led to artifacts in the display. I'm happy to report that the core and memory ran together smoothly at their respective top speeds without any issues.
