Yes, I have tried 1.2 volts, core stays below 50C but they seem to crash faster the more voltage I give them.

Edit:

I will run my cards at stock volts and stock speeds for 30 mins in furmark now, and report my VRM temps. These temps are recorded with probes placed on the BACK of the graphics cards, on the following area: http://i274.photobucket.com/albums/j...0_gtx_back.jpg

One thing worth noting, is that the top card is always (under load) around 10 degreed hotter than the bottom card on that specific area.

Edit2:

PCB temp in afterburner is 36-37 on both cards under load.

Wow I thought you only went up to 1.087. Any difference in max clocks with different drivers?

I have only tried 260.99 so far. I have attatched a file with my VRM temps after 20 mins of furmark. I will try a fan now.

Ok well, placed a fan over it, and it is increasing a bit slower, but in the end, it's hitting 70 degrees either way... So there is definitely something to it..

Hey this is interesting... I gave the cards LESS juice, pulled them up to 785 in core and turned on furmark. Have been running for quite some time now (over 30 min) and my sensors register 86C at most on the back on GPU1. I think GPU1 is getting hotter because it is so close to the NB and the RAM. Either way, it is not crashing as of yet. I will leave it running a little while longer. Perhaps there is something to this VRM overheating thing.. Damn I figured a fullcover block would definitely do the trick.

Do you think my block is making bad contact with the VRM's or is it a common thing for the cards to get ultra hot on the back side? I used the supplied thermal pads so there should not be any problem really...

Edit:
The VRM temp of GPU1 is still climbing, slowly... It's 86.5 right now. No crash though.

Edit2:
The cards are running on just 1000mV.

Edit3:
I gave them 1025mV now and turned them up to 800 in core. Ran for 10 mins no problems, but the backside of the VRMs hit 90C. Did not crash though. Isnt that very odd???

So, by now I'm quite sure it's the VRM's getting too hot. So I am about to buy a few heatsinks, but they are out of stock for an entire month (Enzotech MOS-C10). I don't know if this is too much to ask, but could somebody buy me 2 packs of these from some local retailer and send them over to me in the cheapest way possible? I will of course pay you for it. They only cost roughly 11-12 USD over here. So thats a total of say 22 usd for 2 packs + shipping. Not sure how much the shipping is though. I live in Sweden. It would be very nice.

Ok. I just added a fan and small heatsinks that I scavenged off of an old motherboard on my GPUs. The VRM temps dropped drastically, but once I push a lot of juice or OC a lot the computer locks up. No black screen, no artifacts, just lock up. Very weird. I have tried giving them more juice, did not help. Any ideas?

I am currently running 815/1630 with 1950 memory stable at 1037 mV.

to run each card individually, the Rampage 3 Extreme has four switches to shutoff power to individual pcie slots (I also remove the power connectors too). max stable oc on all three 850/1700/2000 w/ 1.087v.

Yeah I know that. I tried getting 850 with 1087mV, but no lock. Computer would lock up just after a minute in furmark (extreme burning mode). The screen freezes, and computer keeps going on. Nothing else happens. No artifacts or similar. Any idea what causes this? Does my card need more voltage or is it tellming me it's had enough?

try 800/1600/1800 w/ 1.087v. some gtx470 don't like to be pushed beyond 800. My Zotacs have had no issues even reaching 865 on some occasions. tbh 850 is too much for daily use, I only run this when Im running benchmarks (vantage in particular) and 800 when Im gaming i run 800/1600/1900 with 1.050v. When Im not doing anything heavy in video (ie browsing the internet) I run stock clocks. I have 5 profiles setup in MSI Afterburner to easily switch between these settings.
