So I recently started trying to overclock my 8350 and while I'm running IBT, HWmonitor says that my voltage drops to 1.2-1.3 volts when it should be around 1.375 while the clock speed also drops a whole gigahertz. Why is this and is it bad?
I had it set to the stock voltage at an overclock of 210 bclk and it was doing this.
Rig: FX 8350, Gigabyte UD5 990FXA, Corsair Dominator Platinum 1866 cas 9-10-9-27, Diamond HD7750, Corsair RM750 PSU, Swiftech H220-x liquid cooler
This is bad because it can make overclocks unstable, theirs is ways to combat this turn of power saving feature you can keep c6 state and and leave hpc on auto. Then go to power control and change load line, over current protection, and phase control to a higher setting, like high, 130%. Keep the memory low like 1066 to remove variable when overlocking, after your overclock try something around 1700, but make sure you check your stability before pushing the memory.
What would be a good LLC setting? In my motherboard there's regular, medium, high, ultra high, extreme, and normal. I also don't think my motherboard has a "phase control setting". Why would keeping the C6 state and HPC on auto help though?
did you disabled cool n quiet?
Because if you not disabled cool n quiet, your cpu clocks down at idle, this is normal, because its a power saving feuture.
For overclocking i would highly recommend to disable cool n Quiet, and also disable AMD turbo core.
I've disabled all the "power saving" features and turbo core.
how high did you overclock?
cause 1.356V is arround stock for a FX8350.
It's throttling.
Could be vdroop or throttling.
I got it to about 210 on blck before it started vdrooping. This was at stock voltage, mind you.
Why would it be throttling?
210 what? Bus ratio?
cause 210 x 20.5 stock multiplier = 4300Mhz.
It seems like a Voltage Throttle to me, i dont know how hot your mainboard gets?
Those Gigabyte boards are a bit of a pain in the ass..
