Many thanks for a swift reply
Yes problem is only at idle, its not a biggie but as I use the program to log average as well, so that figure then is inaccurate on newer versions.
Orange box at top is VID (I have not renamed sensor, this is as HWiNFO detect and apply naming).
Red box is Vcore (I have not renamed sensor, this is as HWiNFO detect and apply naming).
I set a VID of 1.255V in UEFI, so VID up top is correct. The slight overvoltage in Vcore is due to adaptive voltage mode/AVX code stress program being used, so not an issue.
Only other change on my system between that screenshot and current system configuration is motherboard firmware, currently 3003, that screenshot is 2801.
I've had this motherboard since about March 15 and been using your program since then for many hours with differing firmware 2601, 2702, 2801 and had no issue on idle vcore. I don't recall an issue with reported idle vcore with program/firmware 2902 but will check.
