problem with my rigs..

[Dpminer]

hi there folks,

i have been searching over google to find similar problem but cant find a proper explanation.

here is my problem.

i have mining gpus rigs as usuale.... asrock h81....6 gpu mosly r9 290/x and some rx 580s.

using dual 1050w thermaltake psu

all  of my rigs are mining with os on usb with simplemining..

i used powered riser like everyone else ...

what happen is when i boot with 2 psu the rig boots fine starts to mine and eventually stop reboot and comeback with less gpus... starts to mine again  stop reboots and comes back with less to even sometime stabilized with 4 gpus other time 3...

what i did since i cant find the problem im only mining with 3 cards per rigs and im wasted 3 pcies slots on every mobo....

i would like to use 6 gpus per rigs....

how are you guy running them without a problem ?  i even ordered the new mobo with 13 gpu but well i cant get 2 psus to work how the hell will i use 3 psu on 1 rigs...

Did you enable 4G Decoding in the BIOS?

and you maybe want to take a look at this topic:

using anything more than 1 psu is such a drag and yesterdays tech, grab yourself a server grade platinum rated 1200w hp common slot psu and breakout board for it, and a 15 dollar 160w pico psu to power the mobo

i have turned pcie mode to gen1 and it seems to be a lot more stable...

i got only and other usb that i have to reformat reinstall the os... usb key seems to corrupt a lot when running ext os.

i might turn to hdd os .  usb are driving me crazy.

my usb thumb drive containing smos corrupting every now & then
I then moved to my 500gb spare ssd (overkill)
but no problems after that

get an ssd, usb drives are cheaper but are not meant to work for what you are using it.
