Best drivers to use with the 7950 would be the 13.2 beta?
would love to see what clocks you achieve as i to just bought a MSi Twin Frozr III HD 7950
Looks like they're finally selling them at speeds closer to their real potential. Now I want a second one . . .My card also has 960/1250 clocks and is on an AMD reference 7970 PCB.
First thing I had to do was remove the cooler and change the TIM. The card was getting up to 90C when I was stressing it. No idea what is going on MSI but they are using TIM like it's going out of style. The GPU was taking a bath in the stuff. It was all over the chip, squeezed out across the PCB.. just terrible. Cleaned it up and replaced the TIM with some Noctua NT-H1 and temps haven't gone over high 60s.
Think I got a good card here, just some early messing, but I have it up to 1200core/1350memory just by bumping the voltage to 1.125. Temps didn't go above 70C. I'm just using the Heaven benchmark 5 loops to check stability.
Not really seeing the best scaling with overclocks or all round performance because of CPU bottleneck I think. The card is in a really lopsided system currently. My wife's computer, which had a mobo die so it went from an i7 920 to currently running an old e6400 @ 3.2Ghz. Whenever Haswell comes I will be replacing it. Nonetheless these are the results :
Stock clocks and voltage
1100 Core / 1350 Memory on stock voltage
1200 Core / 1350 Memory on 1.125V
Seems to be a decent overclocker, but these are just 5 loops of Unigine. I can't even run BF3 or another intensive game on this rig with this crappy CPU. Hopefully I can get this thing to 1.3Ghz core with 1.2V or so. :thumbsup:
should be able to game with that chip. My friend has a E6400 w/ HD 6870 and he plays BF3
Edit: when my new board and card gets here i'll test my C2D E6550 @stock w/ HD 7950 in BF3
Maybe I'll copy BF3 over to it later and see how it runs. I'd really like to be able to try it in my nvidia machine and compare it to one of my 680s. There is no way I am taking apart my water cooling to do that though. Way too much hassle.
1200 Core / 1350 Memory on 1.125V
Update 2 - Updated to 13.2 beta. No HDMI display detected. Put the 6950 back in - instant HDMI display detection. I guess I got 1 with a bad HDMI port. Weird, because the DVI works flawlessly.
RMAed the card last night. It got a little complicated because I had already used the games code. Newegg is shipping the new card today and paying to ship this 1 back. Can't complain at all about the service.
Thats a really nice oc on the core. My card needs around 1.2v to get over 1150mhz and if I use over 1.2v it gets too hot. I think I need watercooling
Anyone seen a noticeable difference in performance since the new drivers?
Got my second MSI Twin Frozr OC today. it's also not on the 7970 PCB (2 6 pin power connectors). HDMI port works perfectly. Stock clocks were also 960/1250 on this 1.I had the first 1 at 1200/1400 on stock voltage. This 1 is the same. It seems to run a little hotter than the first 1. I'll pull the heat sink and put new TIM on it.
Just received my Gigabyte HD 7950 WF3.
1st: It's a hell of a huge card hahahh, love the design, it's silent and efficient.
2nd: The specs state that the core clock is 900mhz...but after installing the card and the 13.2 drivers it's shows at 1000mhz on stock clocks...Am I lucky or it's a misprint on Gigabyte website and on the box?
3rd: A tiny OC and i'm now at 1100/1350!
you have received the newer version of the card with probably the FZ1 boost bios and 1 ghz boost clocks. your stock voltage would be around 1.25v and mostly locked voltage. but as you already have seen its easy to get to 1100 - 1150 mhz at stock voltage.
Read on Guru3D that this BIOS is not the best since the 1.25v stock is too high and sometimes makes the card run hotter than it should.
I midly OCed the card to 1100/1350 using CCC with Power control at 20%...should I flash my BIOS to the new F43 or leave the FZ1 there and enjoy the ride?
