Etherum RIG Setup

[Mauricio G. B.]

hey guys, so recently i got tasked to build a 6gpu etherum mining rig, and i got everything but the problem lies here, the computer boots normal with 3 gpus attached, and with the other 3 it goes into a weird af green bios like really oldschool shit, or just shows a black screen with a white flashing _ like cmd, the specs are as follows

6X RX 570 STRIX OC gpus

TB250-BTC PRO Biostar 12x gpu mining Motherboard (only 6 will be used now)

HX1200i Corsair 80+ plat PSU

Celeron G3930

8gb lpx ram

windows 10 pro

all cards are on Sata powered risers but im at a loss here im not interested on setting up to mine and that thing i just want the rig working

Have you verified that all the cards work separately? Maybe its 1 bad GPU you need to just RMA

Personally I'm not sure what's going on. There's no way you're pulling too much power so thats out.

 

I'll leave it to someone more experienced in mining and crazy gpu setups.

the manual of the moetherboard told me to set all pcie to gen 2 if i was going ti mine, but again im at a loss here  i was pretty sure all i had to do is connect them all and have em show in the device manager

I'm not sure either, but I have read in forums that people claim the mining mobo's are buggy.

At what point does it fail? Can you run 4 GPUS, what about 5?

 

Have you tried booting it with Linux?

 

Can you screenshot/take a picture of the weird green bios for me?

 

Have you got the PCIe extra power connector on the mobo populated?

pcie gen 2 in bios as well as above 4g enabled. no more than 2 pcie risers powered by a single sata cable. 

 

start with 3 cards, add a 4th does it boot normally? when you get to the one that fails switch the riser out. i've had bad risers right out of the box.

This may be a silly question, but have you enabled miner mode in the chipset section of the BIOS?  The system will not work with more that 3 cards without that setting enabled, and it is disabled by default.
