Thanks for the clue on what to check and you are indeed correct - GPU-Z 2.7.0 reports the stock and current clock values are the same (1295/1750, vs. 1200/1900 reported by MSI AB) so something buggy going on for sure, and you get a merit! Disabling the iGPU on the Onda mobos has led to a lot of problems with NO video showing up, and it not being recoverable without removing the CMOS backup battery.

EDIT - so the plan, I guess, is to order a DVI-D to VGA adapter (so I can continue using my KVM switch with my other Onda board that has all NVIDIA cards) and see if I can get the mobo to disable the onboard VGA *and* enable one of the PCIe GPUs for video out.

Again, I don't use these new drivers, but on those old I need HDMI dummy plug, it's working without it for me, but I know some RX cards need it. I use it because Teamviewer resolution that is terrible without it. I'm using one of those 2 dollars HDMI to VGA convertor, it's fake not the original, but it does the job Cheesy
All my rigs have Z270 chipset.
Thanks for the Merit Smiley I was thinking that I will have it because of my guides, but they not giving me almost none Cheesy

Holy shit, that worked! I just happened to have an HDMI dummy plug that I purchased for my RX 570 rig but didn't end up needing. I plugged it into the first RX 560 on the Onda rig and now the correct clock rates are showing up in GPU-Z while Cryptonight hashrate jumped by ~22 H/s per card (after stopping and restarting xmr-stak)! I'll try Claymore v11.0 on a <2GB DAG Ethash coin (MUSIC or UBQ) in about 15 minutes and update this post.

I have just one merit left to give out, but if solving a problem I didn't even know I have isn't worth a merit then this forum is screwed...

UPDATE - okay, looks like I need to get a dummy plug for *each* card; the hashrate jump in xmr-stak was ~66 H/s total and I *assumed* that it was spread equally per card, but when I loaded up Claymore only the first card shows a higher hashrate of 14 MH/s while the other two are still at 12.9 MH/s. Still, the dummy plugs are cheap and an easy fix!
