копаю на Gigabyte GA-770T-D3L 4x5770 видях работают нормально. При подключении 5-ой, одна из карт перестает работать. БП=750W, 4 видюхи работают на 510W, т.е. в запасе еще 240W. Связь идет через x1-to-x16 pci-express extender.
Hi, currently i have 1 rig with 4x5770. Now on every 5770 i put one CM fan so temps are round 68-74C.
Currently clock is 950Mhz(gpu)/300Mhz(mem) with factory voltage. I tried it on 1000Mhz 1050Mhz. GPU was stable but Wattage and Temps were so high so i cant see point to do it for 10MH/s per card. Now i stopped on 950/300 i guess its best OC for 5770.
Currently i'm mining in hand-made case. GPU are clocked to 1050Mhz(gpu)/300Mhz(mem). Temperatures are around 69-72C. Wattage is 570W. Everything seems fine till now. But now i got 1 more 5770 and wondering will it be some problem to install 5th videocard to this motherboard. Im not talking about temps and clocking etc. My point is on Wattage and Motherboard support. With wattage i cant see problem because 570W + ~115W = 690-700W max. and i have 750W PSU.
