Hi everyone!

I just got my Sapphire 7970 OC. smile.gif I bought it open box from Newegg.

Do any of you have a stuttering issue when playing Skyrim? It's like microstuttering one would get when running cards in SLI/CFX. I'm assuming it's a driver issue for now since I didn't exactly do a clean install. I uninstalled my nvidia drivers, rebooted, and promptly installed Catalyst 12.6 drivers. The rest of the parts for my X79 upgrade arrive later this week so I'll see how it runs on a clean Windows install when they arrive.

Besides that, Crysis 2, Deus Ex and some older/less intensive games run perfectly.

EDIT: ASIC 80.2%

I only got the stuttering issue when I started using Eyefinity, otherwise all my games ran fine on a single monitor (Skyrim as well).

I have no issues getting MSI AB 2.2.3 to stick with my overclocks and overvolts. I used the -xcl method as suggested and I did download the 2 .dll files and pasted them in the MSI AB folder. They were very easy to find, it only takes a few minutes with google. thumb.gif

I don't think the 600 series for Nvidia goes past 3 monitors, but I may be wrong.

EDIT: ASIC 80.2%

try 12.7 for skyrim.
and make sure you use app profiles also.

Try out the sapphire bios I linked or the 950mhz bios (which I have also seen has a higher TDP limit). I saw little to no difference to the 7970 bios at the same clocks. BTW, I was running 1680x1050, nothing so high that timings alone would justify 22 fps min vs 19 or so min in Heaven 3.

Now, I'm just a bit annoyed why there wouldn't be any consistency in TDP/Powertune between brands. Maybe some manufacturers allowed higher settings due to their better VRM designs than reference? BTW, what is the reference 7970 setup, 6+1???

I am also dissapointed that the gigabyte windforce 7950 doesn't have a heatsink on the VRM. At 1100@ 1.23 v, using OCCT or any other app that pulls max current (22 A input at 12v), the VRM's can get up to 100C! What is safe?

Can I remove the gigabyte heatsink without voiding the warranty, and add a heatsink to the VRM's using thermal tape?

I'm sure this post will be lost, but...
has anyone bought the new Gigabyte 7970 Ghz card?
I'm trying to find that card's BIOS.
