Bios and CPU Z Reporting Completely Wrong Vcore

[miketen587]

A few weeks ago I posted a similar thread looking for answers/fixes to this problem but to no avail.

One person even said the same exact thing happened to him but did not have a fix for it.

Basically, ever since I installed my Asus DG sound card, the Vcore my bios and CPU Z are reporting is wildly inaccurate. They are both reading .288 Vcore, which is obviously completely wrong. I wouldn't even be able to post at that.

My 3570k is OCed to 4.2 Ghz @ 1.21 Volts. The OC is completely stable and has been for months. Motherboard is an Asus P8Z77-V LX.

The ONLY place that correctly reports my Vcore is the field in the Bios where I manually enter the fixed voltage that I want.

PC is running completely fine otherwise. This is just bugging the hell out of me.

I would look for a bios update it is just a quirk no worries. If it bugs you that much call Asus or email them they might have a better answer or you might prompt a fix from them.

Just noticed there was an update for my Bios released last week on the 3rd. Hopefully this fixes it.

Bios update didn't fix anything....This is irritating me more than it should. I hate not being able to figure things like this out.

When you take out the sound card does it go back to normal? If so i might suggest looking for new drivers/firmware for the soudcard also. If none of these does anything then I guess live with it or try a diffrent sound card.

Yeah, try pulling the sound card and see if it starts reporting correctly. If it's showing correct in BIOS though, I'd be led to believe windows should see it nearly the same however I could be wrong.

Also, if it does fix the issue maybe try swapping the slot it's plugged into to see if it works correctly in a different PCI slot.

Taking the card out does not revert it back to normal. I know for a fact that this issue started immediately after the sound card install though because my AI suite was giving me a Vcore notification in the bottom right corner of my screen, which it had NEVER done before. I've since uninstalled AI suite to avoid the warning, and the fact that I never used it.

Did the sound card drivers/software affect the voltage readings by chance? It's an off chance; but it is possible.

when you installed the sound card did you pull power from the wall and let the mb drain?? new mb like the asus keep a small voltage standby on the mb/cpu..you may have zapped the mb without knowing it. have yoiu tried using the clear cmos jumper with power pulled from the wall??

Yes. I shut down, unplugged from the wall, and also shut off my PSU. I have tried resetting to optimized defaults within the Bios, but have not tried manually resetting cmos via the MB. I'll give that a shot.

Clearing cmos via the jumper on my MB didn't work either. Vcore still reading .280 in bios sensors and CPUZ In fact, according to CPUZ resetting cmos didnt even drop my clocks back to the stock speed of 3.4. Instead they went down to 3.8. All other settings in the Bios were reset as expected however.
