I have 3 rigs all with bamt and all of them hanging and crashing randomly im so tired i need help since im having sex with them about 5 days already.

74 03 89 50 04 c7 03 00 00 00 00 c7 43 04 00 00 00 00 00

kernel 451.130533 eip [<cl0c2486>] generic_detach_inode+0xe7/0x139 ss:esp 0068:f2a43f44"

i tryed different flash drives and different settings. I tryed stock clocking and OC. I tryed downvolting. I tryed different PSU's, nothing helps it still hang up.
And i dont know the reason.
fans allways at 100%

System is :
mobo: msi fm2-a85xa-g43 + 4 risers 1-16x
cpu : a4 4000 box (with box cooler and stock heatsink)
cards: 4x280x
ram: 2x4gb
psu: 2 x 1000wt (1kwt per 2cards)

please, help!

Im trying to mine LTC.
Mobo is MSI FM2-A85XA-G43 and 4 video cards are 280x.
PSU is 1200wt (galaxy hof 1200)
Risers i have are all 1x-16x, trader told me that there is no any difference to use 16x or 1x for mining, but 1x is better for ventilation.
I did't know that i can connect 1x to 16x slot on mobo which is true

BUT, when i start mining system is shuting down (using BAMT 1.5 and cgminer).

I have Sapphire Toxic, wich is working great and have 1256 by default.
With 3 cards its working fine.

It is problem with 1x risers? I need power risers? They are to expensive due great deficit and 1.5 month of waiting.

Пока в МСК нету карт, продам свои
