post #14831 of 38704
Hey,

I ordered two HIS 3GB 7950's and I was able to OC @ 1030/1250.

My crossfire setup runs hot! When i am playing battlefield, I put my fan at 100% to keep at 75C.

IS this acceptable? I am running specs:

i7 3770k @ 4.5gz
16gb pc1333
2TB HD
2x HIS 3gb 7950
h100 Corsair
NXZT Phantom Full Tower.

My cpu stays frothy, but my cards a little toasty.

The Crossfire is using my bottom card (I think..) so is my setup running to hot do you think?

Edit: I found out I had AMD OD turned on also. I turned it off. I am now using Trixx only. Still input would be appreciated.

Edit: And I cant seem to get a stable OC >< I am hoping for around 1030 core clock, and 1500 memory >< Help needed.

Again spotted a problem with 12.8 drivers. Assassin's Creed II's shadows flicker. I seriously hope that downgrading the drivers will help because I'd prefer not to RMA this card even though it is a bad overclocker. And this problems was happening with stock AND 200mhz underclock on core and mem. So should I install 12.6 or 12.7 beta drivers now?

There is definitely something wrong with your system. Needing to push fans @ 100% to obtain 75°C in burn @ only 1030 should make you think about checking you thermal paste and/or your rad screwing.

You'll need to pull down your temperature before you even think about overclocking..
As for the cards, are they reference or what? I assume so seeing as you haven't mentioned "IceQ" or anything. How big is the slot between your cards?

Have you got a sidefan or such?

EDIT: I finally got my card today! It's so big! redface.gif
It maxes at 60c at stock, but I only ran that once.. I'm now running 1GHz on stock clocks.
How do I check my ASIC quality? smile.gif

EDIT: .64.2%... Wow redface.gif

I had serious issues with 12.8, FireFox and CF7970, a quick Google search showed that I was not alone.

Wow lol
Mine is stable from using the 12.8 drivers from the 6850's.. It took a few seconds to boot the first time, but after that it's fine. I needed to reboot but that's about all smile.gif

60c at load is awesome, and 1ghz without a voltage increase is solid too. Especially for a 64.2% asic.

I'm excited for my IceQ's to arrive.

I think people need to not use driver sweeper or cccleaner.

Opposite for me, 12.7 betas failed for me, 12.8 so far so good

12.6 were borked for me, and 12.7. 12.8 are fine. bizarre.

Have you tried reversing the crossfire bridge? I had problems with CF when my bridge was mounted "incorrectly" for my 5870s and at times CF would not even work. If I mounted it correctly, all the problems went away.

*By reversing I mean just switching the top of the bridge with the bottom of the bridge.

This only happens with CrossFire enabled , do you CF, your sig says you don't ?

CrossFire works fine.

 

The problem for me, is CF with the 12.8 drivers and firefox combo. Every thing else works fine.

 

Never heard of the CF bridge having a top and bottom, don't you think they would mark them (master/slave) if there was a certain why it had to go on ?, maybe you just didn't have it mounted firmly the first time.

 

Its not a problem now anyway, as I am back on the 12.7 and all good again.
