Question Voltage rising above the Vcore set in Bios following heavy gaming opinions please?

[Nath83]

Hi, over the last few weeks I've overclocked my CPU, GPU and Ram and have seen good performance leaps with reasonable temps under 70c whilst under full load. I do have a concern though and this is surrounding VCore/VID in Bios as it is jumping up significantly following lengthy intense gaming sessions playing AAA games. Having read through many useful pages on here I experimented with different voltage plans and in the end decided on an adaptive offset-1 at 1.295v with the lowest vdroop/LLC setting at 25% as previously at 50% it spiked even higher. I have also changed my power mode to balanced and GPU power to adaptive. Included images below.

During gaming everything runs stable, according to HW monitor the VID is staying within VCore however if I go into BIOS following a good 4/5 hours of gaming what appears to be the V Core or VID (depending on how MSI display these things) seems to spike up dramatically, in this example in BIOS it is recorded as high as 1.464v. It's worth mentioning that sometimes when I go to BIOS following a gaming session of a couple of hours everything in the VCore seems normal but lengthier sessions it spikes up and very slowly starts to go down in the BIOS. I've included photos of my OC settings in BIOS for you to see.

I've had the PC 5 years spec as follows is;

MSI X99A Raider, Click 5 latest Bios, Windows 10 64b, I76800K OC to 4.2mhz, NVIDIA RTX2070 OC up to 2025mhz/Mem 8088mhz , DDR4 3X8GB OC-3000mhz, Corsair H55 Liquid Cooling , Corsair 750 Watts CX750 PSU.

Should I be concerned with this spiking so high is there anything I can do to stop this?

Does anyone have any advice they can provide me please?

OK, well after much experimenting I appear to have fixed this myself and will share my solution.



I increased my offset to - 0.004 in bios for my voltage, I also lowered core voltage down to +90 and power limit to 100 in MSI Afterburner.



Pleased to say I am no longer getting huge spikes of voltage,
