"There are some mainstream motherboards on the market that overclock very well. The GF9300T-A is not one of them if you are using a 1333 FSB processor. With limited overclocking options in the BIOS, its very difficult to push your components higher than 1333 FSB. With that said, I gave it my best shot. The board did recognize the E8600 and set its speed correctly but the Mushkin memory was automatically set to 800MHz. There is no CPU voltage adjustment in the BIOS, so pushing the processor past stock speed did not provide stable results. Attempts to get the memory to its rated 1000MHz resulted in data corruption and led to an operating system reinstall. While I was eventually able to push the RAM to 900MHz, I would not recommend overclocking this board with its limited headroom and the lingering possibility of data loss."
