[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 1426

post #14251 of 38704
Well I upgraded my 7950 (GB Windforce) for a 7970 (XFX with Acellero). Very pleased so far. ASIC 72%. Just have standard OC Core 1125 with Memory 1575. According to the ASIC the voltage was at 1175. Sure enough my VRM temps were up to 90 degrees with BF3 with extended play on max settings. I actually lowered the voltage to 1150 and the temps are now staying around 62 deg with some augmented fan settings. Pretty pleased. Haven't been able to unlock OC further with AB no matter what (can't find the dll's yet). But won't be able to do much till I get a case fan directly on those VRMs. BTW got the 7970 with Accelero for $320 (used Can $)... less then my 7950!

Nice score. I prefer 72-75% asic cards myself, best ones since they get the best balance of volts vs leakage imo. As for your dll/oc issue, you can read about a couple methods here as well as get the dll's.

Normal?
OC is a hit or miss, my card does 1250mhz easily, even 1300mhz in benching.
still run it at 1200mhz when gaming
no reason to get 50mhz more for a few fps as it pushes the cards limits.
925mhz to 1200mhz is a great step, 1200 to 1300 or such not so much.

You might get more out of it using watercooling.
low asics seems to give good wc effect due to high leakage of the transistors.

My ASIC is kind of low, but I did not get great results. Luck is the main factor when it comes to OCing. Since a lot of us watercoolers are getting crap OCs.

My asics are high so I didn't really expect great numbers but I was hopeful that my wc loop would help. 1250mhz appears to be my max which is acceptable, if not spectacular....

Using MSI AB, i can see the memories voltage slider to be available but no matter what i try the modification never applies. Is it normal or am i doing something wrong ?

You are doing something wrong, but question is what.

I have read somewhere that it's a problem with the latest msi ab 2.2.3, voltages doesn't stick. Apparently it's missing 2 files. They suggested using msi ab 2.2.0, see how it goes.

it shouldn't matter as it looks like we have the same card. my card does 1125mhz at stock voltage.
