I had to flash to a Sapphire vBIOS to clock the GPU higher because of CCC limits. I've read the 7970 has a default GPU voltage of 1.25v, but again depending on actual clockspeeds this figure probably varies anywhere between 1.1v - 1.25v. You will most likely get a higher default GPU voltage, I'm not sure exactly what this would be it probably depends on the vBIOS you flash and how high the clocks are with it. You will get much higher CCC / Afterburner etc limitsĦ. Flashing to a 7970 vBIOS will give you tighter memory timings (this is why its important to check your memory can handle 7970 speeds +50MHz)ĥ.
You will get higher default GPU and memory clocks (obviously) so check your card can handle 7970 clocks and add 50MHz to your memory speed - this is explained below.Ĥ. Failing that both the VTX3D and Sapphire HD7970 vBIOSes appear to be unlocked versions, they flashed right onto my MSI 7950 with no issues at all.ģ. If you can't find a 7970 vBIOS from your manufacturer, you can try a "generic" ATI 7970 vBIOS. Its safest to flash a 7970 vBIOS on to your 7950 using a vBIOS from the same manufacturer as your 7950. If your 7950 is made with a 7970 PCB, you should be fine flashing a 7970 vBIOS.Ģ. Now, theres been people concerned with putting a 7970 vBIOS on their 7950 so if it will alleviate those peoples worries heres some info to bare in mind ġ. So it should be good for flashing a HD7970 vBIOS on to. Default GPU voltage is 1.03v on this card and ASIC quality is 75%.įrom what I can tell between this card and HD7970 pics on the web, this card looks to have a HD7970 PCB. The memory on this card is Hynix H5GQ2H24MFA T2C 148A. Now thats all sorted out the card seems to run much cooler when stressing it with Unigine Heaven and load GPU temps have dropped 3c from 74 to 71 with the card clocked 1100 / 6300 1.125v.
Good job I did the latter as well, when I took the plate off one memory chip was barely being covered by the thermal pad so I repositioned that and the stuff thats peeled off before the memory pads get applied clearly hadn't been peeled off properly in the factory because part of that wrapping was stuck to the pad still, causing two of the memory chips to get very sweaty. Using Afterburner to OC the MSI card to 900MHz core (no memory OC) I'm already significantly ahead in 3D11 scores compared to what I've seen reviewers getting using the new 7950 "boost" vBIOS, my score is 79xx instead of 74xx.Īs I always do with any card, I've already had the cooler off and replaced the TIM as well as removed the plate cooling the memory / VRMs etc. By best I'm not talking highest 3D11 scores or anything like that, but the least buggy with the most performance improvements for proper gaming.
#Playclaw 5 plus dx9 drivers
Through testing I've done so far the Catalyst 12.7 beta drivers appear to be the best. Mainly the thread is to report on my own findings but also to provide much more detail on the 7950 than the other thread and to answer any specific MSI 7950 questions people might be wondering about. Title says it all really, this thread specifically is for HD7950 tests and related detailed information.
