Two MSI 7970s work fine independently but BSOD when crossfired - Page 2

Are your 7970s watercooled? If so, what's the highest voltage you've been able to do? Afterburner seems to stop at 1.3v regardless.



Interesting that you mentioned the CPU needing a voltage bump. Almost a lightbulb moment for me, actually, because about a month ago the fan on my seasonic 1250w failed, so while I was waiting on the RMA replacement I had to use my backup PSU. Not the greatest quality, so I put everything back to stock while using the backup. I got my Seasonic back, but I have not re-applied my overclocks. I can't remember if the BSOD issue started happening at that point or not, but it's certainly worth trying.

No, I generally won't try to oc too much until somethings under water. I have a XFX 7970 on the way with Ek wb and will be ordering some thermal pads to bin the cards I have. The TF3 does 1100/1500 on 1.17 though. Promising. I also just am in the middle of purchasing another Matrix. tongue.gif
There are modded Trixx that will do 1.38v. Look around and you should find it without too much trouble.

I got ahold of another Z87 MPower today. Installed it, reinstalled windows again. Reinstalled drivers from scratch, and they installed perfectly this time. Guess i'll return my other Mpower and keep using this one. Not certain the Mobo was the problem, but I'm happy and don't have the time to keep diagnosing. Swapping hardware in a watercooled PC is no fun at all.

I agree in the middle of doing a new build, binning cards,ect,ect. Selling off some of my current hardware to fund a build and new loops. I want to do a scratch-build, have the equipment available and skill, but the amount of time involved is crazy.
