GPU-z: 0,938
HWmonitor: 0,95
MSAB: 1,112

Which one to trust? ;-)

First, make sure your readings are for the same voltage load vs no load and from the same sensors.

Software can't be guaranteed to be 100% accurate, especially with a new card design.

Others that have more experience than I will chime in, I am sure, but it's never a bad idea to set up a hardwired measurement if you want to be confident in the readings.

GPU-Z - 0.938mv actual 2d clock voltage ( I believe )

MSAB - 1.112 Targeted 3d voltage

If that is what you were asking

Well, I read about the .125 overvolt headroom, so I was counting from 1.112 the last time I oc-ed this card (it ran perfectly fine at 1.200).

They above v's were all under no load. When I start the render test in GPU-Z, that one shows 1.146 and HWMonitor shows 0.950.

I'm a bit confused now, so what would my question be?? :-)

Not sure if I am understanding what your asking exactly but i'll give it a go.

Too check your default voltage the easy way to do it is to right click on top of GPU-z and hit ASIC quality, The % will indicate your default voltage.

As for the voltage in different programs, Just use GPU-Z as it seems most reliable in my opinion.

Keep in mind that in GPU-Z it will show actual voltage so it will change around a lot. It goes without saying that it is normal for the voltage to change around a lot. You will find that the max volts it pulls is higher depending on the program you are running.

If this didn't answer your question or it was nothing even close to what you wanted to know, Sorry bout that.

Which card type or brand should I get on the 7950's

I'm trying to understand and learn, so I'm glad you replied. My ASIC is 80.9 btw.

I was under the impression, since I bought this card, that my voltage was about 1.112 cause AB read that. The .125 oc margin would be that my max voltage was around 1.237.

So the question is, I guess: taken into account the .125v OC margin, what is my stock voltage?

edit: just rebooted and started GPUZ.. VDDC is 0.797. When I start the render test it goes up to 1.064. I have not started MSAB yet, just stock speeds in CCC.

I believe 80-85% ASIC quality is a stock voltage of 1.050mV but i could be wrong.

Not a big deal anyway, If you go over your voltage allowance of .125mv it will just shut down your gpu and then you will know. ( will only shut down when in 3D clocks though of course, if you are over the limit)

How far can you push the core with the 1.112v?? When I install MSAB and just unlock voltage, and restart AB, it shows me 1.049. Then when I hit the reset button, AB jumps it too 1.174v. Seems that AB is adding the .125v to our stock voltage on it's own. Since I've seen that, that's where I've left it. If I push higher, it becomes unstable.

Guys, can anyone run any form of eyefinity on the 7970? I've tried all of the drivers and none of them give me an option in CCC to "create an eyefinity display group" however I could easily do it with my 6970 which I recently sold off. Thanks!
