Currently have a 1.6A / 8SRX / PC2700 Samsung DDR as my main system. The 1.6A is o'c to 2.25ghz @ 1.575v @ 142FSB and the memory is running at 177 @ 2.6v. My memory can do 185 but then I had to lower the FSB to 140 to get that speed, and the benchmarks ended up pretty much the same. Unfortunately I can't get my 1.6A to run stable at 145+ FSB (it boots into WinXP but can't run Serious Sam w/o crashing), and I'm reluctant to push over 1.65v on the cpu since I'm still using the stock hs/f.
The 8SRX is really easy to overclock. In the BIOS, when you increase the FSB/MEM, the PCI/AGP will also go up. But then you can just scroll back down and lower the PCI/AGP settings w/o affecting the FSB/MEM. It has 33/66 PCI/AGP settings when the FSB/MEM is 133/133 or 133/166.
