if he does not overclock.. yeah its 158.  but a waste

not posible

maximun demand on the 6990 is 294W per card.
and u still need the power for the cpu/ram/mobo

you could do it with 2 psus.  one 850w for mobo+2gpus and one 650w for the other 2gpus. this way u can save arround 50 bucks.

i dont use the render/mine rigs

i use the ones i have on the front desk.

1st the case is open.  2nd i cuted the plate that holds the motherboard, leaving enougth steel to keep integrity . 3th the mining/render rigs r on the basement. where i have A/C and i leave on a place where the average temp is 6 °C.   the cards run now at 56°C~66°C  and now the temperature of my building is better the other ppl thx for it.  an average of 16°C. without turning on the Calefaction.

note i have 6 running now. 6x4 gpus stucks at customs.  i m8 need to pay a fee to get them out. exceded the limit per person on the import. lols

EDIT:
for those having problems with the 4th CARD and this MOBO  try upgrading the bios
you can find them here http://www.msi.com/product/mb/890FXA-GD70.html#?div=BIOS try with 1.6 or higher.

China. direct import. from manufacturer.
my hardware supplier is an importer direct from factory...

why? do u need some?

hello

im BlackSnow, _{i want to keep my real name secret if possible}

im a 3D animation studio owner.

im 36 yrs old

im gonna start renting equipts for 3d animation. near an University.

and im gonna use the same rigs for minning. as side kick buissness

Edit:

the rig specs on my signature is the one i will use to mine and to render the
costumers files

the edition ones have the same specs but Phenom II X 6 1090T and 8 Gb Ram
and 2 GPUs only and 2 500 GB raid 0 HD

Is to get an estimated profit only. thats not my main buissness.


i need the equptment. i do 3d animations. mining will be my side buissness. to pay bills.

the worst thing.. that i will sell one or 2 of the rigs. bc i will still use the other 10. for 3d animation.

What do u think of this Rig
