Hello, I am trying to overclock my i5 750 on my Biostar T5 XE SLI+CFX.
I can get up to 3.7GHz intel burn test stable at 1.35v with 178 base clock and a x21 multiplier. However, I can't get the CPU to stay at 3.84 which is a 183 base clock at x21. You see when doing the Intel Burn Test it switches the multiplier down to 20 instead of 21, which is 3.6 GHz. I can't figure out why it is doing this, max temps on load go up only 1c across the board (64, 61, 58, 58c to 65, 62, 59, 59c). I have disables speedstep, C1E, TM function, and Max CPUID Value limit.
I'm starting to think temps. aren't the problem, and neither is voltage because I increased it from 1.35v to 1.4v without it helping.
