I recently purchased an AMD Phenom ii X4 965 Black Edition and was eager to do some overclocking. I overclocked it from 3.4Ghz to 3.5Ghz within a half-hour of its installation and then my PC would no longer boot. When it finally did, my CPU speed was lowered to 800Mhz and I could never figure out why. Turns out my Motherboard, after 3 boot failures, sets the CPU Multiplier to x4 and the CPU Voltage to 1.05.
I slowly cranked the multiplier and Voltage back up to original levels and the system would no longer boot, again! It got reset once more.
Then I hastily cranked up the Multiplier to x16.5 and everything was good and stable. I cranked it up to x17 and it wouldn't boot on the first attempt, it did on the second however. I thought everything was fine but the next morning, I had 3 boot failures and I was sent right back to square one.
So just what is the problem here? Why won't my CPU run at its Stock Speed? I've disabled Cool 'n' Quiet, C1E, CPU Thermal Throttle, Quiet Fan, hell, I even tried raising the CPU Voltage to 1.45V because perhaps Stock Voltage was insufficient and my PC seems to struggle booting up when my CPU is at its Stock Speed and this makes no sense. I've actually had to underclock it to get things to work as they should. Any ideas fellows?
CPU: AMD Phenom ii X4 965 Black Edition
Motherboard: Asrock N68C-S UCC
RAM: 8GB DDR3 with DRAM Frequency clocked at 667Mhz
Graphics Card: Nvidia Geforce GTX 260
The only idea I can think of is that the PSU doesn't have enough power but it outputs 700W, that's enough for a second GTX 260! I'm truly, truly stumped.
