Hello guys, I got few rigs set up on this Onda B250 D8P motherboard and all share the same problem - everything works great on every possible setup, except when you put card in 1st GPU slot(the 16x one), then it gives out constant 4Mh/s from a GPU that is in the first slot and other cards get unstable hashate(keeps jumping up and down), which also gives SMOS monitor wrong info on monitoring. It works perfectly on a 7 card setup with 1st slot being empty.
just got the same problem. With all my motherboards. Long time lurking and the fix is:
1) load bios
2) system agent
3) gpu settings
4) port 1 was set not like others. just set the same settings for port 1 like for others.
Wow thank you 100x . Spent all day looking for this solution.
If anyone is having trouble on the v4 motherboard just look for port settings and match port 1 settings with port 2 and 3 (set everything to auto).
On version 1 Port 1-4 are disabled.
But the fix suggested online was.... Bios/Chipset/System Agent/Peg Port config/Peg 0:1:0 Max Link speed = Gen2
I have 12 RX570 ITX Pulse cards running but cant seem achieve ideal performance.
Max is 307mh @ 1520watts.
Anything over 26mh requires massive increase in watts.
Anything over 950core and wattage sky rockets.
anything over 1780 memory and system crashes.
0.2mh/watt is acceptable but not the low mh.
The exact same card when tested on my desktop performs @ 29.5mh with 1090core and 2000memory.
Is anyone having success at hi hash using AMD cards on the Onda board?
Is the suggested bios mod used for fixing 1st pcie slot problems (which appears to only exist with AMD Cards) hampering my performance?
Any help would be much appreciated.
Im using SMOS.
Id like to achieve 29mh per card like they're capable of.
Im missing 15% of their true performance with the onda board. Or am i chasing a rainbow?
