Topic: B250 Mining Expert SMOS, no more than 8 cards (Read 309 times)
Nvdia or AMD guys ?
I have this MB as well and had endless trouble trying to get more than 8 gpus running on it. My OS is Windows. I eventually stumbled across a YouTube video:
Asus B250 Mining Expert Bios Configuration

I changed the Bios settings on the MB and literally straight after that, I was able to set up and run 11 gpus hassle free
May be worth checking it out.
My virtual memory is set higher than yours though - pretty much set it as high as I could.
I wasted so much time assuming the issue was an OS issue. SMOS has a pretty good reputation so I would definitely check out the MB bios settings.

How do you set the virtual memory???
I have 13x1080ti running stable on W10, i3-7100, 4Gigs of ram.
Been a while ago when I installed this rig but from the top of my head the most important things are:
-set the PCI settings in the bios to GEN1.
-Try removing all the cards from the device manager make sure you have also hidden devices turned on.
-Install the cards in multiple phases and give windows the time to recognize them this can take a really long time!

as far as I know this motherboard supports 12 cards without any firmware. Firmware BIOS makes and more Chinese via risers.
Thank you all for the help. I was able to get 10 cards running. I am unsure what solved it as I did two things at once. I changed to 2 4gb ram sticks, and changed slots based on the diagram provided. I will update when I get PS to power all the cards at once.
Also note not all slots are equal.

If you are referring to the ASUS B250 Mining Expert motherboard I have heard but not experienced first hand that they have problems with Windows and cannot run more than 10 cards.
I also heard that Hive OS solved the issue as it recognized out of the box 13 cards and started mining right away.I think you can give it a try with Hive OS.

I am trying to put together three 12 card rigs on these boards. I have one running stably with 8 cards. As soon as I add anymore cards I get issues. Upon boot SMOS recognizes all GPUS, they OC properly and display an appropriate hash rate. Immediately after, any cards over 8 crash to showing 0MH, weird values for clock temp and fan speed, and become unreachable by find GPU command. They are no longer in contact with the software. My HW is B250 Mining Expert, 3930 CPU, 4gb ram, OS on pen drive, two seasonic 1200W power supplies. I feel like I have eliminated risers, cards, ps, and slots. I believe the issue is software related.
Possible issues
The PS does not have enough connections to put 6 or 7 cards in group A. I can run 5 cards from each of the power supplies I have. I plan to change this in the future. Is it sensitive to not filling a group. For the next two rigs can I get three smaller power supplies and put four cards per group?
Low ram, the manual states assigning 30GB of virtual memory. Is this necessary or possible in SMOS. Would 8gb total ram be better?
Cpu?
Anyone have experience with this particular issue? I have more boards coming and can swap it out just in case that is the issue, but I want to get this solved before I order anymore components and I want to do that soon. Thanks for any help yall can provide.
