Need help with some OC and weird restarting power issue

System Specs:

GA-990FXA-UD3 with F2 BIOS version
FX 8350 W/ Corsair H60 liquid cooler.
Corsair vengeance 1600Mhz CAS 8
Corsair Prof series HX750W
SLi 660ti
Windows 7 64bit

I have been messing around in BIOS trying to get this overclock stable by testing it with Prime and I cant for the life of me. I had it stable at 4.2Ghz with no need to up the voltage. My goal was the get it up to 4.6ghz and put my liquid cooler to use. I keep upping the voltage and now I am at 1.42v and still dont have stability. It blue screens, or restarts the computer or will run the stress test and a couple cores will fail. Do i need to up the voltage even more or is there something else im not factoring in? Also my idle temp seems to fluctuate between 26-30. Is this a normal temp with this cooler and the OC at 4.6?


One more thing. When i first put this build together a few weeks ago, when i would restart it it would always just...restart. Now whenever it restarts whether its forced or I click restart, it will power off, then come back on. Sometimes it will power off, then on then back off then back on and continue loading back into windows. After everytime I edit something in BIOS and save, it restarts by shutting everything down and booting back up. What is suddenly causing that? I preferred when it just restarted rather than completely cutting power to everything...

HALP!

If you are unstable at 1.42v, bring it down to the last stable voltage and see what that does. If you get anything like that again like you were at 4.2, you might have caused permanent damage to components. If you get any BSOD's, post what caused the BSOD.

Bringing voltages too high can cause BSOD, lockups, etc. You need to lower the voltages or else you will burn out your CPU. Reboot voltages may be too high, causing the computer to power off and start back up again. If you mess with the voltages, the computer will shutdown and turn back on. That is normal. 26-30C is normal for that overclocking voltage. You might have already done damage to the CPU. I suggest that you turn down the voltages IMMEDIATELY.

why did every tutorial say to up the voltage till it is stable then? How is 1.4v too much when many people OC a 8350 to 4.8ghz and have theirs at 1.45 or even closer to 1.5? i have brought it back down to its stock 1.33v and it still shuts down and restarts instead of just restarting...

and where are reboot voltages? I never changed anything besides the CPU volt...

everything is stable at stock. when i bring up the multiplier to 21 (4.2Ghz) I get errors. at stock voltage. basically, i cant overclock at all no matter how much voltage i give it. volting at 1.42 shouldnt harm or do any damage when my motherboard and cpu are rated for higher than that.

this is a brand new build, about a week old. I just tried OCing today. When i load optimized defaults in BIOS everything is Ok and there are no issues and the computer restarts without having to cut power and powering back up. its when i try to increase the multiplier or anything it does that.

First, when you installed the motherboard did you use standoffs in ALL the holes, and no EXTRA standoffs? It sounds like a bad motherboard or possible grounding issue. There is also an off chance of a rogue memory chip could cause random restarts, but being as the CPU is also acting strange, I would guess bad mobo.

So make sure the motherboard isn't shorting out somehow (like a standoff touching a circuit somewhere), and try flashing the BIOS like CompGee said.

If you can get codes from the BSOD that would be helpfull.

Do you have a case speaker installed, so in the event the CPU is beeping it could give you a Beep Code?

im not getting random restarts. the computer only restarts if im stress testing after overclocking. When everything is set to optimized defaults everything acts normal. can play games maxed out no problems, etc. when I OC and test with prime I will get a restart after a couple cores fail. I usually get crashes/restarts rather than BS.

replaced CPU with exact model CPU. Same thing. It only gets errors or will sometimes restart in Prime. Played about an hour and a half of metro last light maxed out without a hiccup. And I had it OCed on stock voltage.

i have narrowed down the weird restart. sort of. When I load optimized defaults, everything acts normal. i press restart and the computer restarts, nothing shuts off. As soon as I go into BIOS and disable things like Cool n Quiet, Turbo mode, etc....thats when it will perform a full shut down and boot up after restarting.
