ok so i have just done all the above from the first post, sweep drivers etc and all seems to be good. so how do i go about over clocking my twin frozr v2. whats the first steps, then what and then what. will report back as i go along.

Doing that now, cheers unc. can somebody be kind enough to tell me the max voltage for a 7950?
also is the unigine valley benchmark ok or must it be heaven?

Uncle Petey · 7 Mar 2013 at 22:14

Depends on the card. What's your stock voltage and Asic score?

Heaven 3, 4 or valley should all be fine. I use 3 myself as I know where all the tricky bits are.

stock voltage is 1031 in AB.
Asic score - where do i get that from?

Uncle Petey · 7 Mar 2013 at 22:19

Right click the menu bar of GPU-Z and click 'read asic'.
Your asic is quite high, judging by your stock volts.

Iirc, you can get away with about +0.125v over stock volts. Don't rush it though and just whack it up. Treat it like a lady and go slow

Find out what clocks you can achieve on stock voltage before you start raising it.

ok 88.1% asic score

@LtMatt

I realized that even though i change me voltage in MSI AB it didn't do anything, HWMonitor etc say its a constant 1.25v under load

Voltage locked card then mate. See how far you can get without changing volts.

Is there a 7950 which is not voltage locked?

Pretty sure the msi 7950 twin frozr is not voltage locked. Rusty can confirm.

K, when gaming my VRM goes to around 85c+. Is this to high?

If you can keep the vrm temp at or below 90c then i wouldn't worry too much.

I have these cards and mine aren't, bought them when they first came out. Currently on 1.225v and 1,200 MHz.

Thanks, good to know. Can't ever see MSI locking voltage. :cool:

Yeah they have been good clockers to date. The only thing they changed was they started putting these on 7970 ref PCBs. Mine are on 7950 ref PCBs though as i bought them as soon as they got released. Not a lot of difference but you just need to check if you decide to water block them like i did.

Forgive the newbie question. But, when you run heaven or valley do you run it at your monitors native res?
Also, what levels of AA For both and how much tessalation for heaven?

Yes run it at your native res. Pick settings that get you around 30-60fps to represent a realistic load on your gpu. I go for these at 1440p when testing an overclock using unigine.

Anyone bought a recent MSI 7950 here?

Yep. Twin frozr v2 7950 with 7970 pcb. Had it bout a month.
