You cannot Edit a BIOS pass a 6990 anymore with RBE. It's not possible to change the voltage into the BIOS with Tahiti (7970)

If you want a great collection of 7970's BIOSes, Techpowerup has a huge one (44 BIOSes total)

This makes me sad, the whole reason I went away from ROG cards.
Why can't we have full editing control in bios mad.gif

I'm at 1080p, would that be worthwhile or is it better spent using the voltage for core clock increasing?

I'd recommend trying it out, as in my experience, some systems see greater benefit than others. If you don't like it / don't see any positive difference, you can always just uninstall. You will see slightly better GPU temps though. If you do try it, make sure to try the MVP version, as that's the one that makes a difference in FPS and adds virtual sync (to compatible applications).

Judging by my own overclocked (but on stock voltage) 7970, I'm fearful of imagining 3 of them running next to each other, unless I don't overclock and run without increasing power limit. You could try a case like Silverstone Fortress/Raven 02 though for very good airflow through the cards.

So my first problem with CFX, visual corruption in Crysis 2 with two HD 7870, and stuttering.

I hope i dont crush any rules, because i have HD 78xx, i am posting here because there is lot of more activity.

I am running 12.8 with cap2, anyone else experienced this?

I've seen artifacts and pop ins in Crysis 2 with every gpu combo that I've tried it with and that includes Nvidia cards.

I've runned trifire 6970 lightnings and 560 ti tf3 all aircooled on the EVGA Z77 FTW. I'm waiting on two more 7970s to run tri-fire. Since the MB allows you to run with an extra slot of breathing room for the top cards, it should cool vastly better than a triple sandwich. There's a few boards that can allow this arrangement (it maxes out at 8x pcie 3.0 on the EVGA Z77). I know the EVGA 4-way X58 can, the Asrock x79 Chamption, X79 Classified., and I think the BigBang x79. Some board do have the this middle pcie slot but their designated as 4x. Here's how I ran the 6970s and 560s:








If you don't plan to upgrade your mb, then expect some high temps in sandwich setup:

I saw pop ups with GXT 570 SLI too, but this is little different, randomly yelow/black vinlys appear on screen. Stock clocks, others app are ok.
