Hi. I have problem with my two rigs. On every boot or reset rig start with different amount of cards. After 4-6 reboots the list is finally complete (10 and 11 gpus). Why is that?. Two different motherboards. One is H110 Pro BTC+ ASRock other BTC B250C. Mixed AMD cards. Does anyone have something similar?
H110 is exciting to troubleshoot, but triple check those 1x adapters to make sure:
- the pins extending through the mini circuit boards are not touching
- the tight routing of cables has not wiggled the 1x adapters out slightly
fwiw: I had to skip one of the PCI slots entirely due to tight fit and not having another 1x adapter I could trim/bend the pins without de-soldering.
After the above, power, overclocking, loose connections are frequent culprits, in these large rigs. The rig above is pushing the power supply pretty hard for depicted GPU 5-11. Enough that 11 was dropping out on every third reboot, prior to adding a 3rd supply using all the same cables, etc.
Depending on brand of B250C, some have been just terrible builds. Hoping you have a good one. I did not.
Both boards worked fine when there was 7-8 gpus. Now, when it is almost full there are some issues.
Btw. How do you managed to show total kW from that cards at the bottom?
H110 has known issues at the ±9 GPU mark, BIOS settings default.
(2) very long threads here is (1) direct to a developer bios discussion:
Actual power can be displayed in 2 ways when GPUs under report to the OS:
- a fixed offset shown here or with a combination of offset and power supply efficiency.
These entries can be found on the hiveos.farm, worker , “Settings” tab
In this case, I have to measure a few power supplies at the wall, and it happens to be 564 in my 10 GPU rig, and 719 in my 12 GPU rig.
