I'm trying to overclock a Q9400. I just put the chip into a new Gigabyte EP45T-USB3P mobo and the BIOS is great in terms of giving me every option. My problem is a strange one - no matter what I do, and no matter what speed the BIOS indicates the CPU will be running at given those settings, the CPU continues to run at a stock 2.66 Ghz according to a couple of benchmark programs. I've adjusted the FSB from 333-450 and several settings in between, change the multiplier, changed the voltage, and various combinations of all those changes. Whatever I do, when I run a benchmark, the CPU tests at 2.66 ghz.
What am I missing? Any advice would be much appreciated as I'm about clueless at this point.
I've figured it out - apparently when you've overclocked the CPU, the mobo has a feature wherein if it detects a flaw in boot up it automatically goes to fail-safe settings w/o changing the visible settings in the BIOS. I stepped it down to 375 FSB and it's now running (and testing) at 3.0 Ghz. I guess the challenge will be figuring out what I can get past the mobo as I assume I can get a lot more than 3.0 out of the chip.
