Just checked my BIOS to see why my CPU was running near 80c idle.. saw that My motherboard had the CPU voltage at 1.65v, I set it manual to 1.4v but the motherboard decided 1.65v was better..

Im calling out the MSI 990FX motherboard on this one. Bad design.

Is this a new motherboard or one you've used for a while?

Its a new one and instead of listing the voltage like normal it list the voltage in grey (non-adjustable) the only option is to add voltage... it looks like this

Voltage.................Manual Option
1.048v..................[+0.3000000v]
1.048v..................[+0.3100000v]
1.048v..................[+0.3200000v].
1.048v..................[+0.3300000v]
1.048v..................[+0.3400000v]
1.048v..................[+0.3500000v] (what I chose)
1.048v..................[+0.3600000v]
1.048v..................[+0.3700000v]

that should = 1.398v (1.4v)

instead it set it to 1.65v Almost fried my CPU

1.048v is not the voltage the cpu runs at, at max clocks, normally (1.3v sounds more like it). The board might have picked some lower power state voltage to show you in that menu. Then again, normally you're not presented a cpu voltage reference for that in the bios like that, as the cpu wouldn't necessarily run at max clocks in bios, so. Guess MSI tried to give people a 'convenient' reference point...

So the board was showing me the low power state? thats counter productive for overclockers and im not sure why MSI would think we care about low power state voltages let alone try to up the voltage? High Power States are where overclockers live what was MSI thinking.. Unless they are going for the "you can tweak literally anything: angle.

Why would 1.65v fry your CPU?

I ran my FX-6350 for weeks at that voltage under water lol If you can cool it, there's no problems.

It's most likely a LLC issue.

yes, it is picking up a low power state voltage.

set it to 0.300 and I bet it goes down to 1.6 volts

I do think 1.65 is excessive even with a good cooler. The socket itself DOES get quite toasty even with great cooling.

Id say 1.57 or so is the most you want for a 24/7 setup. 1.65 would be like one of those "hey I got it super stable for a week" type of thing

No 8350 ever made has a VID of 1.048 volts. ( the range of 8350 I've owned/played with is from 1.28v to 1.38v) VID + offset = voltage applied in the case of my 990 Gaming.

great... so do you want to limit it down to the actual model you are trying to use or are you condemning a whole line up

this sounds more like user error than anything a bios is designed to do.
