Thank you man! You helped me fix the problem! I set the 2D/3D profiles and the problem has not occured again!

I am looking at heatsinks for the ram and vrms, coupled with this type of fan combo: http://www.newegg.com/Product/Product.aspx?Item=N82E16835192026

Since I will open-up a MOBO slot with this mod, then a fan combo, mabe not the cheap one above, sits in the opening and blows air directly on the card - a pretty neat solution.

Yea I didn't mean the block won't work

When I first put muy maze 5 on mine my vrm temps shot to 110c in 30s of kombustor

I had to put a 90cf to really get the temps down on it

If I ever get another xt ... Up in the air well see what the rest repair cost is I'll post how to put a block on the vrm the right way

IMO, ASROCK has to be making some of the best motherboards ever! I have changed so many components on this mobo, everything from CPU's, GPU's, memory and soundcards, and am in my 7th year of usage! Not to mention the countless hours of gaming and also using it as my primary PC for everything else. This mobo is just amazing!

Glad to hear that your mobo is working fine. I guess it will support most of mobo, but some mobos are not compatible.
I guess I have to find out tonight.

I think you just have to make sure you have the latest update for your motherboard from what it sounded like, so older OEM boards (which are probably what most people had that were complaining on newegg) are sol.
I don't think they have to be UEFI themselves, just need to be capable of supporting it.

No new updates after that. Anyway, can I crossfire with 850 watts PSU?

I don't recall seeing any UEFI warning message in the description of my Myst card when I ordered it from Newegg. Some type of warning should be posted. Seems like an odd requirement that many people may not think about.

I'm pretty sure it's only for UEFI motherboards that have the problem. Using a non-EFI bios on a uefi board with a uefi bios on the video card simply doesn't work. Also on supported boards, make sure you manually set it to PCIe gen 2 or revision 2 instead of auto select if you do not have ivy bridge. This is a big deal as well because it will always default to the card's gen not your supported.

I'm diggin' these cards for the price but I'm about ready to start bios flashin' and I've only had them since Thursday, I just realized they're down clocking to 925 when I push them to near 100% no matter the temp.
Some games they also like to drop gpu usage randomly when you push them, at least that's what I was noticing in Spec Ops: The Line the other day which I think is what causes it to shutter every now and again in the game.

They're the .028 bios if you wondered.

How are the crossfire temps? Are you keeping your case open all the time?
