You can try searching for undervolting tutorials to reduce the voltage.
Also Gigabyte brand usually runs hotter than others.

not liddat count...280x around 250W.. mobo/proc around 100w

so total for 4x 280x +mobo/proc/hdd etc = 250x4 + 100 = 1100w so use 1200w or 1250w PSU is ok.. good powersupply can output 90-100% 24-7 no problem.. heck some even have another 50-100W reserve to give you..

Hmm.. looks like GPU 0 isn't getting enough power to me.
760W for 3x R9 280X is a bit tight.

how the hell you got 4 cards (8 PCI-E) to connect to a 6 PCI-E PSU?  physically already hint that 3 GPU is pushing it on 760W PSU..

OIC, what way you use to join the two PSU? using green+black wire hack or add2psu?

You need to share the Ground pin for PSU1 and PSU2. Use a Jumper cable to connect the black wires of both PSU together.

well guys, we're on USD600 back after all those mtgox shit.

seriously if you had the money for two low power platinum seasonic PSU, should have bought a 1050-1200W instead and less hassle.

in this case, split up to 2 rigs.. each with 3 GPU.. 

I'm thinking whether or not to move this thread to Finance section as it can be a good discussion thread.

running 1.050v for 280x ... stable but averaging about 710kh/s

how exactly do i cash out from LTC to an maybank account?...
LTC - BTC - mbb?

best way for a msian?

for multipool, from my experience they get you much better btc/day usually compared to only mining ltc
i've tried 2-3, best is still middlecoin, very stable. last week was abit lower though, they had some problem
profit will fluctuate daily but overall still better than ltc only

you can check here, there's always some coins better profit than ltc

aiks goldfries , why move thread to finance subforum? i thought there's one thread already inside here?

tired of feeding trolls?

tonight yc?

btw, anyone can confirm if a gpu is connected to a monitor, despite the monitor is already turn off, still can reduce the khs of the gpu?

mind if i ask a noob question, how do i get my bitcoin address?

can win7 support up to 6 independent r9 280x? or need win8 to do that?

and how do i know if my --powertune 30 is really using extra 30 or less power?

btw, ive seen 6x Sapphire Toxic R9 280x running @ 810~830khs tho.. but its a power hunger ofcz.
