I've had my intel E6750 (stock 2.6ghz) overclocked to 3.2ghz just by changing the FSB to 400 with a multiplier of 8 for probably over a year now. I just went to put in new ram (4 gigs of ddr3 1066) and when I did, I saw the CPU overclocking was reset. I tried to put it back to 8x400 and it wouldn't take. I put the old ram back in (2 gigs of ddr2 1066) and the CPU still won't overclock. I even raised it by 1 single mhz and still nothing. What could be the problem?
