post #18011 of 38737
Errrr..... unless I'm missing something, the voltage slider in AB seems to change the VRM voltage. Changing from stock on up to 1.2v makes the VRM voltage go up but the vCore is still at 1.17v. I mean is this how its supposed to work on the newer cards or what? If it really does just adjust the VRM Volts then no wonder why the temps go nuts on the VRMs.

Dropping it to the "Stock" settings for voltage, it reports 1.061v, moving it to 1.2v brings it up to 1.137v (now all this is on the VRMs) (It also makes the VRMs draw an additional 20A). The Core stays at 1.170v no matter where the slider is.

I think you're in the wrong thread, this isn't the "is AMD up for sale" thread.

VRM output = vcore input. if one is moving and the other isn't, then it's time to pull out the DVOM. VRM "voltage" is only what it is because of what vcore is set at - you can't arbitrarily "set" vrm voltage.

Also, sometimes voltage is reported based on what it's set at, not what it is. IDK about the 7.9k cards, but with the 6.9k cards it reports desired output voltage, not actual core voltage.

From what i have found on my wf3 7950's is after making changes to the vcore in AB the only program that shows a change of voltage is the monitoring of GPU-Z. You also need to take into account voltage drop under load.

Hmm, well I suppose AIDA64 could have them mixed up.... Let me see if there is a newer version and if it fixes it.

EDIT: Newer version did nothing, if however GPUz is correct (which this is the likely scenario) then AIDA has them swapped which is what I was thinking after checking GPUz. Looks like I will have to swap the names on them so they show up right on my G510.
