ok well turn off crossfire and hook up your 2nd monitor to that card try that and see if that works. also try mining whit just 1 card and see if that works. also are you ocing you cpu? and try taking all your ram out but 1 stick and see if that helps. if not run driver cleaner and then restart you pc and install the newest amd drivers, after that idk what to try. you have 1 worker for each card right?

1 you need to earn about 82 coins to pay that off so that's going take a while
2 dotn know
3.1 dont know
3.2 about 1.3 safe if you have good cooling
3.3 if you have good cooling and a good card 950-1ghz
4 keep it under 80c and you will be ok but if you are over voting it keep it under 70c as you vrm will got hot
5 yea looks good to me

google furmark and run it on both your cards and watch the screens to see if you see any artifacts (could be dots lines or hard lock that kind of thing) and watch your temps if they get over 80c you could have a overheating isus
aslo have both cards hoked up to monitors and not in crossfier when you do this and if after 1 hour they both look good that would rule out the cards ad being bad and then we can go form their

yes you should have card 1 card 2 card 3 and card 4 you need to plug a mopnter in to the 2end card or make a dummy pulg for windows to turn it on, and then once you see all 4 you start 4 workers 1 on each card and you good

what model psu is it? form what you said is doesn't sound like to good of one you might have 40amps of power on the 12v if it a cheep one. a good 650 will be way better then a cheep 750

also, what are the risks in doing that? Could I possibly fry my card if I do it wrong? Is it something someone relatively non technical could figure out?
Yes it involves overwriting the stock bios (voiding warranty) with another bios. Yes you can fry your card by flashing it to 6970 bios. But there is a safer alternative, you can write a custom 6950 bios to the card which unlocks the extra shaders, but leaves the clock speed and voltage at stock 6950 levels. Then you can manually overclock yourself to safe levels. You will need to use winflash I believe it is called, to write a downloaded bios over the existing bios (make sure to back up your existing bios) to unlock the extra shaders. This can only be done on reference 2GB 6950s btw. You can unlock the shaders on any 6950 using RBE AFAIK. Reference 2GB 6950s can just be flashed over with a reference 6970 BIOS, but that's not exactly safe. Like you said, you should use a custom one that doesn't touch clocks or voltages. no you cant if the pcb is not built by amd you cant unlock it |

http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.668135&nm_mc=AFC-C8JUNCTION&cm_mmc=AFC-C8JUNCTION-_-EMC-060911-Latest-_-Combo-_-Combo668135-LM1A&PID=3668349&AID=10440897Combo buy on PSU and DVD drive. Also has a $30 MIR on it. OCZ isn't as good as Antec, but it's much cheaper, 2 dedicated 12V rails @ 25A, and it's modular so you can more easily route wires. 700W is more than enough for this system. As far as unlocking shaders. Yes, if you do it incorrectly, you can fry the card. Any time you are messing with the firmware of a piece of hardware there is an inherent risk of something going wrong. These 2 cards do not have a dual bios switch, so you can't just flip a switch to recover. Having said that, I'd still recommend it. It's a nice little performance bump, and as long as you follow along with a good guide, there is barely any chance of frying something. Just unlocking the shaders without touching voltage should give you a decent little bump. They you can overclock normally. If you found this information useful you can tip me at 1Cwmb2SftoPABQtqKoGoG68WdqDs4NRcyp wrong you cant flash a card that's not a stock amd card and its not a stock card whit out the bios switch. if teh card does not have amd by the pcie connector you cant unlock them and whit a reference card if you brick it you just switch back jsut dotn put a 6970 bois on it unlock yours or dl the asus 6950 whit the volt mod bios |
