MSI 670 PE does not have a voltage increase?

post #1 of 79
Thread Starter 
I did a search to see if someone else posted about it but there really wasn't a clear answer.

I was on the MSI forums and they claim that being able to go up to 1.175 on core voltage is the over voltage that they were referring to, even though a stock card can do that. So if you were thinking you could buy a 670 PE and adjust the voltage, don't bother. They are no more special than any other 670 with a custom cooler and PCB.

I hooked a voltage meter up to the card and even with all the sliders turned up, it still was at 1.175 for the core voltage.

I understand that it doesn't say unlocked voltage like a lightning does, but one would think that if you advertised over voltage that it would go higher than stock.

Just clearing things up so other people know.

Edit: On the plus side, this is a really good card and stays nice and cool compared to a reference model.

I know for a fact they do have unlocked voltage. I own one.

Now I've never tested with a multimeter but I've hit clocks that I could not hit prior to the release of AB 2.2.3 (which allowed voltage increases).

My biggest problem though is that I'm being throttled by the power limit. Once it spikes past 100-102% it throttles the voltage and core clocks.

Do you have the newest version of after burner? Plenty of people have posted increased clocks with this new version.

Does your voltage actually go up though?

And yes I have the newest version where you can turn it up to +100mv.

All that changes is the TDP goes from 80% to 100+% but the actual voltage I read from the meter stays the same.

Edit: If I'm doing something wrong I want to know, but as far as I can see only the TDP changes and not the actual voltage.

I thought it could go up to something like 1.2 V instead of 1.175. Is that how it's supposed to work?

Can you overclock higher? If you can, then yes the voltage is rising. Also the only way the TDP could rise when doing the same task is if the voltage is higher.

None of the applications (like gpuz) will report voltages over 1.175 though.

It's fully unlocked voltage. AB lets you go to 1.275v on the slider.

TDP refers to the cooling (thermal design), not the power or voltage the card is using. Weird that nothing is changing on the DMM, as G3RG asked can it overclock any higher?

I believe for kepler the power % is the percentage of the TDP that the power consumption has reached. So if it shows a higher %, it's consuming more power, but has the same TDP.

Could be right, kepler is weird with the auto overclock & power % depending on temps & stuff. These things used to be simple.
\Would be nice if nvidia goes back to the 'clocks you set are the clocks you get' way, less confusing...
