HD 7970 TRi Fire Battlefield 3 MP freezeing !!!

post #1 of 5
Thread Starter 
Hello Geeks ,

i have some kind of unique problem with my 3 x HD 7970 Stock clocks.when i play Bf3 on my 3 LED @ 5760 x 1080 Using TRi Fire so the game locks up after 10-15 minutes but when i play game with only 2 cards Crossfire game runs perfectly fine.This tryfire gives only problems with bf3 not with othergames like crysis 2 high textures or wioth Alan wake or COD MW3.i have 1500 watts of PSU 80+ Gold so PSU is not the problem neither GPU is kaput because i can play all other games only bf3 is problem.i checked the VRam used in bf3 caspian border map and it went to 5000 MB as soon as the Vram touches 5000MB in MSI burner the game will freeze up? how can bf3 use 5000 MB of Vram now ? with 2 x 7970 i checked bf3 was suing about 3600MB of memeory according to MSI burner.i also checked with ULPS on and Off but same freezing with Tri Fire.I have updated to latest AMD drivers with latest Application profiles and i even tried beta drivers but as soon the memeory touches 5000MB according to MSI burner the game will freeze including my PC.my cpu is 100% stable @ 4.4GHz - 3930k.what the hell is it.

xD, kaputt hä?

VRAM usage is added from all cards in Afterburner so VRAM usage will be at ~1666MB/card when you expire your crash. As you told you only have a VRAM-load about 1300MB/card when running in 2-way cf it's confusing why a third card should cause an extra memory load of 300MB. Possibly it's a memory leak bug in Battlefield or in the famous AMD-drivers.

Also maybe one of the RAM-chips on the third card is damaged? Have you allready tried to exchange the gpus among themselves?

For private interests: What settings do you run BF3 on, i got a VRAM-usage about 2200MB/card playing at 5040x1050 ultra/4xMSAA...

regards...

When u say freeze up, do you get a sound loop or brrrrr sound? Must you do a hard reset or is cad still responsive?

I have tri fire 7970 and struggled though some problems with bf3. I would first try all cards at stock, then i would try bumping voltage WITHOUT bumping clocks. I actually needed to bump my base voltage a smidge when i played at stock clocks. Also try bumping vram volage to 1.62 at stock clocks as well.

I have other solutions as well but need to know how its crashing.

Also, i would avoid using cat 12.9 beta with afterburner, the two do not play nice together. I went back to 12.8 after discovering 12.9 caused screen corruption when overvolted with afterburner And would eventually crash. (12.9 cap 1 can be used with 12.8)
