im new on the forom so my name is Nicolas, im 24 and i live in Monaco.
My config is :
Mobo : Crosshair V CPU : FX 8150 Ram : Ripjaw 1600 mhz 16 Gb GPU : 2x ATI 7970 3Gb HDD : 2x Seagate 1 Tb 2x Vertex 4 150 Gb PSU : 1kW seasonic platinium Case : Corsair air 540
The system is watercooled (cpu, mobo and GPU) 1 D5 pump and 5 fans be quiet (4x140 mm and one 120).
I bought the harware one year ago exept one gpu. When i bought the second one i tested the system one month before to change for watercooling. And sometimes when i restart my compure i loose one video card 😕 I mean i cant see the card in the device manager no display on the screen (Im not in crossfire mode).
So i checked : - Drivers uninstal and instal it worked one or two times. - Power connection and i notice i didnt plug the EZ molex. - BIos updates
It work fine and i watercool the system. Guess what ? My second card disapear after one week of testing ! I tried again drivers, an other psu (1200w) and many things crazy/stupid and still no change.
My cards are plugged on pci slot 1 and 2 (i read the mobo's manual after :mad:)
Ok the 2nd slot doesnt work with16x but why did it work randomly ? And why when it work i have no perfomance issue ? I cant see differences on benchmark when i bench separately. On crossfire mode the difference is close.
I also plugged the 8 pin atx on the mobo's top and the 4 pin is free do i need to plug all or just one ?
