BIOS Voltage

Danny862 · 17 Jul 2013 at 09:51

I have had this motherboard and CPU for a while now, but the same problem has always persisted.

If I set the BIOS voltage to, say 1.543v ( I know that's quite high, but it just proves the point

)

If I go onto CPU-z it shows 1.568v

If I go onto HWMonitor it shows 1.58v

Which one is correct?

Thanks

CPU-Z most accurate in my experience. Best test would be a multimeter if you have voltage points on your board

Ok, I don't think my board does, it didn't even have VRM cooling until I added it myself.

Is 1.58v ok to leave as it is as long as my cooling can handle it, or is that far too high?

Cheers

1.58v seems extremely high, what cpu and board do you have?

I presume the one in your signature?

Correct, It is a Phenom II 955 Black Edition, and an MSI 870A-G54 (FX) with added VRM cooling because I don't want any explosions in my rig

Its cooled using an Artic Cooling Freezer 7 Pro. but that will be replaced later this week.

Do you think there is a cause of this problem, or is it just incorrect sensors?

Thanks for all your help.

I believe if you are putting 1.58v through that chip, I would expect a fire to start very soon.

I have the v-core on my (Phenom II 965 BE) set to 1.275, when it was running at 1.44v (Automatic) the chip would stress test at 80 degrees, under a similar heatsink to yours.

You want the v-core to sit around 1.3 with that chip.

Ouch. That could be a slight problem...

I have read that 1.55v is the max 'safe' voltage, providing that the cooling is sufficient to keep under the stated 62c, and the motherboard has decent VRM's.

The problem I am having is that I don't actually know what voltage is correct, I have set 1.48 in the bios, but CPU-z/HWMonitor etc are all showing higher values. Its just really odd...

All temps seem fine though to be honest, I have used prime95 and never hit anything ridiculous, but I am in a cold room.

I think my motherboard is just poor standard, waiting for payday might be the best thing to do.
