Hi all,

I'm having issues with my H110 Pro BTC+. It refuses to boot (don't even get BIOS) with more than 9 GPUs installed, on the 10th i get the issue, 9 works fine. I've followed the miners guide and ensured both molex plugs and the Sata connector (so 3 in total) are connected on the motherboard and are also using 3 separate cables back to the master PSU. Can anyone help? OS doesnt matter since it doesnt get that far.

Setup:
H110 pro BTC+
Intel G3930 CPU
4GB Ram
500GB Sata HDD
ATI Rx Vega 64 GPUs
3 x Corsair HX 1200 PSUs (1200 Watts each).

Is there perhaps some sort of undocumented issue with the board not supporting these cards? They require two 8pin PCI-E power connectors each, my power draw should be fine though, I have one PSU dedicated to the mother board and the other two PSUs for the GFX cards. Apart from that anyone got any bright ideas? Sad

Install windows 10 fall creators update build1709. with latest amd drivers(for amd GPUs) will work.

Thanks for the reply but the OS doesnt matter since the rig doesnt even get to the BIOS stage? Running windows 10 anyway. I'm thinking it might be the cards PCI lane power draw thats too much for the board @ 10 cards. Each card requires two 8pin PCI-E connectors so they are pretty hungry things! No spec from ASRock on what the board is capable of though.

You need a processor that can support more PCI Express Lanes.
The following is an excerpt from Intel website for Intel g3930 cpu:

Expansion Options
Scalability 1S Only
PCI Express Revision 3.0
PCI Express Configurations ‡ Up to 1x16, 2x8, 1x8+2x4
Max # of PCI Express Lanes 16

NB. Some of these lanes will be used up by other devices e.g. SATA

Also, as in the previous comment, this is a Bitcoin forum not Altcoin!

Thanks for answering my question, rather than the previous poster who wasnt much help - noted about the wrong forum. I'll have a check in the bios see if theres anything i can disable to free up some lanes! Cheesy

Hi,

I checked into the PCI lanes point and its not an issue, plenty of other people are running this board with 13 GPUs on the Intel G3930 Sad
