I have 5 cards on mobo, 280x. Using 2xPsu, 1kwt and 700wt.
USing BAMT 1.2
OC' on gpu to 1100
Card GPU0 droping kh/s after 15-30min of minig.
Slowly loosing speed from 770 to 550 and lower.
Other cards are ok.
Tempr is 55c
What can i do?

how to make BAMT 1.2 work with APU and  4 cards?
When i enable APU in bios cgminer dont start properly (i made changes to configs)

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.

Now i have "kernel 251.130495 code cf 4b cl 8b 53 04 85 d2 74 18 8b 03 85 c0 89 02
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!

even my 4 x asus 280x dc edition dont run smoothly with 1.1v and 1000 core
with enermax 1250w revolution
so i aded 550wt hiper yesterday and it runs without any crashes now

this one will manager 5 cards without power risers with 2 x 1kwt psu ?
(r9 290)
MSI FM2-A85XA-G43

I solved the problem - add 1 more PSU!
1200wt is not enough for 4xToxic at default configuration. Yes you can undervolt, but i want IT ALL! since OC is very good show for kh/s

Какая хрень?
Судя по СМИ сейчас любой повод - повод. И собственно так всегда было с биржами. Любыми. Любой повод - влияет так или иначе ну курс.

потому что надо ценность набивать, тут же нету Бернанке-Путина с заявлением "Так, вообщем за ларками будушее, зарплату думе в следующем году - ларками. Я сказал."

seems like problem is in toxic, due http://www.anandtech.com/show/7406/the-sapphire-r9-280x-toxic-review/4
it can eat u pto 450wt  my god...

i tryed to use 3 of 1X slot + 1of 16x slot
and and 2 of 2x slot + 2 of 16x slot

still its shuting down

what should i do? seems like person of the year is not going to help in my situation ( https://images.weserv.nl/?url=i.imgur.com/gwVOD.jpg&fnr ) ?

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.

я кстати возьму даже по 12 , пишите

Нет бюджета - нет предложений.

пробуй, это дефицит

если кто скажет где 280x дешевле - расскажите, на авито только сказочники
