Overclocking vcore voltage is different in bios to that I'm hwinfo

[Guest]

Hi,

I have been recently overclocking my AMD FX 4170 cpu.
I have been seeing the multiplied from 200 (4.2 ghz) to 234 (4.9 ghz)
The vcore was set to 1.5525 v.

All was fine, stress testing. Then my voltages spike up to 1.68 volts. Even though I have not set it that high?

Specs:
Gigabyte GA 78lmt usb
AMD FX 4170 (4.9 GHZ)

Thanks.

this is always the case. every motherboard is going to have a variance between what is set in the bios and what software will report. furthermore if you test the "actual" vcore with a mulitmeter you will see that that is different also.

also your voltage spikes are likely due to vdroop which is a normal occurrence. though too high spikes are not good. you can use llc(line load calibration) to minimize some of these spikes but it can only do so much and it comes with its own set of problems.

So is a spike of 1.68 volts okay ?

1.68v is too high

4.9ghz is also very high for your chip. lower your overclock until you are under 1.55v
