can anyone with asus b250 mining expert share their bios settings with smos?
i have tried many combinations of settings with 9 cards and smos registers each card but mines less tan 4 hashes each card, i have manyhours trying and cant find good answers online
What GPU's are you using, this info would help?
I have the same issue. Currently I have 4x 570 4Gb and 1x 580 8Gb.
I have 2 more cards I did not test with the mobo yet and 3 more on the way, all RX 570/580 4/8Gb.
Otherwise I have a more general question as well:
I had SMOS running in 1 rig on an SDD.
Can I take this SDD and use it to run SMOS on another rig? Or does SMOS udpates itself and becomes dependant to the HW it runs on (just like windows does)?
EDIT: I forgot to say these 5 cards were running fine (28-29Mh/s) on SMOS on a Z170 PC Mate. Now that I switched everything to the B250 mining expert I have this low (and varying) hashrate problem.
I solved my problem. It was quite stupid but you have to know it: don't use the damn 16x PCIe slot!
After I moved the riser from the 16x slot to a 1x it solved all my hashrate issues.
The above solution did not solve all my problems. The hashrate was good for a while but then went back to crap.
I followed the advice on Reddit and filled my PCI slots in the numerical order (I had read elsewhere it did not matter). Now that I did this my rig is mining at the expected hashrate again.
F*** me it's still not stable. It can run stable for like 6 hours and then the hashrates start to go up and down.
Yesterday when I was running with 5 GPU, it went OK with all of them for hours. Then only 1 of the GPU went down to 3-4Mh/s and the others were all fine.
In the evening I added a fan blowing on the little chip that some people say overheat on the B250.
Then I plugged in a 6th GPU and started mining again.. It was stable for a few hours only and then the issues started again. Not just 1 GPU went down to 3-4Mh/s, many did.
Could it be bad risers? Can they they somehow work for a while and then start causing issues? Identifying the bad one would be hard since they all appear to work, at least for some time.
Could it be the power? I currently run this on a good EVGA gold and a not so good Cooler Master (I had to RMA a corsair, that's why). The only other thing I have running on this breaker is a single light and the fan to cool the rig. The wires are a bit old in my basement where my rig is.
