I7 860 msi h55m p31 newbie, need some assistance.
I've just installed a Hyper 212+, and it's working perfectly, but now I'm attempting to overclock it. I can't push the multiplier beyond 21, and whenever I increase my base clock, the BIOS automatically adjusts the vcore. So when I set it around 170, it raises the vcore to 1.5v. Running Prime95 froze my computer during that process. At about 160, it drops to 1.4, and I disabled Turbo Boost.
I'm unsure how to prevent the BIOS from automatically raising the vcore. Also, I don't know how to change my vcore manually, and I can't find any settings in the BIOS.
Here are some links for reference:

Many adjustments can't be made... the arrow keys just skip over it.
The CPU voltage isn't the vcore, because the BIOS says the maximum it allows is under 0.4v, so I didn't try to change it.
What changes should I disable for overclocking and what steps should I take?
i've identified the cpu core issue. the number in the bios indicates the rate of increase, not the total amount. the base is 1.21, and setting it at 0.1 brings it up to 1.31.
currently, i'm at 1.4v with a clock speed of 3.8, and the computer freezes completely when running prime95. no bsod appears. i have to manually switch off the psu power to stop it. i've tried 4.0, 3.8, and 3.6, all resulting in complete freezing. temperatures are normal (around 65-70°c) while prime95 runs before freezing starts.
i haven't changed the vtt or pch settings—they're set to "auto".
i've turned off c1e eist, spread spectrum, and virtualization in bios.
do i need to adjust my ram, vtt, or something else? the temperatures are fine, but the system is extremely unstable. i suspect the voltage settings on my parts are too low, so i might have to configure them myself to prevent freezing.
I’m struggling to get my CPU to stabilize. The temperatures stay stable regardless of the settings (even at 3.8 GHz or higher), but the system freezes after around 20 minutes when running Prime95.
I installed it at 3.2 GHz with a base clock of 155 and a multiplier of 21.
The RAM is DDR3 dual-channel, with timing specs of 9-9-9-24, a memory ratio of 5, and a DRAM frequency of 1550 MHz. The voltage settings are: DRAM 1.651, PCH 1.1, VTT 1.345, Vcore 1.4, QPI ratio 16 at 4960 MHz, and C-state disabled.
I suspect I might be doing something wrong with the overclocking process, but I’m not sure what’s going wrong.
It seems like this is more of a progress log than a technical issue, but having the details would help.
Adjusting the voltage and disabling CPU phase control has enabled me to run prime95 at 4ghz. It hasn't crashed yet, though two of my cores are overheating significantly compared to the rest. Core 1 is at 55 degrees, core 2 at 79, core 3 at 50, and core 4 at 80. Threads 4 and 5 in prime95 are producing fatal errors, while all other cores are operating normally. Prime95 has been running for about an hour now. It seems I might need to replace my heatsink soon. At the moment, none of the cores have exceeded 85 degrees, which is the recommended limit according to my research.
Edit 1: I suspect the other two cores weren't overheating because the threads failed and I didn't reset them. I wasn't expecting you to need to restart prime95 after a thread crash. I thought it would reset itself.
Edit 2: I now have vcore at 1.25, CPU overclocked to 3.7, and ran a small FFT for an hour—everything was fine. After switching to blend, I've been running for about 15 minutes so far, and everything is functioning well. Temperatures are between 69 and 75 across all cores. I plan to run another test this morning after blending overnight, hoping it will establish a stable overclock base that I can expand from.
Right now my CPU runs at 3625mhz and it looks like it's stuck in an FSB slot...
