nice clocks lol i wish my 7970 would do over 1150 but that seems to be where it sits to be 100% stable.

Hey guys, just picked up an MSI 7970 OC tonight to run eyefinity with. At 5760x1200 in borderlands 2 the car is reaching 95*C even with the fan ramping up to 70%+. It also seems to idle around 65-70*C. I understand it will run a little hotter due to more screens, but this seems a little too much. It isn't hot in my house and my Switch 810 has plenty of airflow to keep it cool. It comes stock with core clocks of 1010mhz, should I try pulling the heatsink off and re-applying TIM to it? Its ridiculously loud when gaming, I can't even hear my headphones over it. I would hate to return it because I already returned an HD 7950 today.

at oc of 1165/1725 i get this error in 3Dmark11, anyone know the cuase?

Workload work failed with error message: window_focus_lost: Display resolution changed

1160/1725 passes but with some flickering
1150/725 passes without flickering

GPU temps never pass 60*C
VRM's temp max is at 66*C/65*C repectively

(Around page 40) AMD admits they found an issue with Crossfire + Eyefinity + (x58 or x79 Chipsets)
Nothing is moving and we think that our issue is not fixable.
Refer to this (BS146) in Erratum section
http://www.intel.com/content/dam/doc/specification-update/core-i7-lga-2011-specification-update.pdf
.

Correct me if I am wrong, but if you have an x58 or x79 cpu and motherboard (doesn't matter which manufacturer) in order to do multi-gpu multi-monitor gaming you must either get nvidia or wait for the 8000 series or hope (which might not happen) that AMD fixes the 7000 series. I am trying to clarify because I was planning to purchase another couple of 7970s and eventually go multi-monitor (once I got more desk space).

Hi guys, I received my Gigabyte 7950 Windforcce edition yesterday and already tried some OC. My ASIC quality is 73,8% for those who are interested.

It appears to me that the stock voltages @900Mhz are really low (max 1.014/1.020 under Load@Bf3; idle: 0.805)

So my current OC is the following:

1100/1300 @ 1149mv (AB)
GPUZ shows the maximum VDDC @ 1.129V while playing BF3.
The VRM temperatures remain below 70degrees as well as the gpu temp which remains below 60 degrees.

Are these good settings? Also, does increasing the memory clock show any significant advantage in FPS? Thanks to the experts in advance!

Those are very nice temps and good clocks/voltage . the hd 7900 cards have a lot of bandwidth. so overclocking memory provides very less gain. also if you have 1080p resolution you don't need to push the HD 7950 much. even at 1 Ghz it will max out every game out there at 60 fps.

do you have a reference cooler. the temps are atleast 15c higher than what is normal. anything above 80c under load is not safe in the long term. if its a reference HD 7970 cooler i suggest you return it and get a custom cooler card like the Gigabyte HD 7970 OC. the windforce3x cooler is one of the best. easily keeps temps below 70c.
