I am putting this here because MSI seems to be ignoring me. Several z370 boards latest bios are increasing the vcore way over what they are set at. I did post in the MSI forums and managed to talk to someone there that did not take me seriously.
This is what I originally posted on the MSI forums: So I put the new bios in this morning after clearing my 5.0ghz overclock and resetting to default bios profile. I then proceeded to, as I said install the new one. It installed with no problem. I put my 5.0ghz settings back in. Then I rebooted. It booted up just fine. I opened up cpuid to check the voltages and temps. To my horror, instead of the vcore being at 1.325v as it should be, it was at 1.44v. Obviously this is way too high. Not only that but while the overclock cycled down with less use, the vcore stayed at 1.44v.
I have been running stable on version 7B46vA2 since I installed it. I have no idea if the new bios runs stable. All I know is when you set it at 1.325 it should stay there and throttle down with less use. 7B46vA3 could cause you problems. Beware!!!
Oh ya, I reinstalled the older bios. The OC is back to normal. I just hope the few minutes spent at 1.44v didn't damage my cpu. https://valid.x86.fr/llddmv
This is the entire post that proves it did not only happen to me but to others on different MSI z370 versions also: https://forum-en.msi.com/index.php?topic=301987.0
This is a simple overclock just using the multiplier. First pic is bios 7B46vA2. Second is vA3. Notice the difference in the vcore.
This problem could fry a persons cpu. I strongly recommend not upgrading the bios to the latest one on any z370mb. Even though it says it will fix security issues.
