You use offset (and LLC level) to compensate for this system calculated vcore.
So, let's say you established that, setting vcore manually, you need 1.360v @ 4.5. You go into your bios, set it to 'offset mode' and, when you boot into Windows and apply a load, you see that it's only giving you 1.345. You'd then go back into bios, set offset to '+' and add .015v in the box, reboot, and you should see 1.360 at load. See below, if you change the LLC level, your offset calculation is going to change.
There is a potential problem to this - for some systems, when the idle voltage drops it's too low and can cause random BSODs. The workaround is to lower your LLC level, the lower the LLC level the higher vcore will be at idle. But lowering LLC also changes your load vcore, so you'll have to do that calculation after you change LLC and boot up, then go back and change your offset + or - (likely add more +). |
Great! Thanks again keto!
AIDA64 says my current VID is 1.3771V. But my Vcore under LOAD won't be at 1.3711v when using Offset voltage since it will drop due to LLC right?
One question tho, when i change the setting to Offset Voltage, do I absolutely have to set either "+" or "-" along with a voltage? Because I wouldn't want to have to set a random voltage and that once I'd boot into windows have like 1.55v under load or the other way around, not be able to boot at all since the Vcore would be too low at IDLE!
Thanks!
