H510 PRO BTC+

Okay, After mounted 29 H510 BTC Builds from 1 GPU to 10 GPUs I'm feel that i Had to give something to Asrock and Community for payback

This is my little Tips to use the H510 PRO BTC+

-Ram MUST BE 8GB or more accord to the manual.
-If you want a stable build with more than 6 GPU use a CPU with at least 4MB of cache like Pentium G6400 or more.
-5 beeps Just indicate that the System hasn't detect a Monitor (maybe not attached or maybe wrong detection)
-Connect 24 Pin connector and 8 CPU Pin Connectors
-Follow the Signage A-A B-B C-C for power the PCIE slots
-Motherboard HDMI doesn't work with HiveOS, after booting the OS doesn't load the GPU, so use HDMI or DP of first GPU.
-You can Bifurcate the mining port 1 to 4 without problems.
-If you want use RTX 3000 on HiveOS you MUST upgrade Bios to 1.30, 1.10 doesn't work well with them.

Servus,
I also have the problem that of my 3 GPU's only 1 is running.
The other two are marked with a red X in HiveOS, so they are recognized, the fans are also running but nothing more.
Setup:
HiveOS 0.6-210@210920
ASRock H510 PRO BTC+ Bios 1.10
3x XFX 6800 XT MERC Core Gaming 16GB
Intel Celeron G5905
Kingston 8GB KVR26N19S8/8

I have searched all forums but have not found a solution.
I also tried different Bios settings, no change!

For me the board works mostly fine with Linux Kernel 5.11
When using Linux you have to pay attention that the onboard graphics depending on your CPU might need a newer Kernel. With 5.8 the my onboard graphics did not work but display output via a dedicated GPU was possible. Ubuntu 20.04 with HWE Kernel resp. 5.11 at the moment works with onboard graphics.
These beeps at boot indicate in my case that no display is connected.

Maybe some knows how to disable that missing monitor beep? Couldn't find any BIOS setting regarding this.

But I have the problem that AMD RX 6000 series cards only run in the first pcie slot with OpenCL. In other slots the cards are recognised for video output but not in clinfo. In the first slot everything works and nvidia 3000 series cards work in every slot.

Did anyone manage to run AMD RX 6000 series cards in the 2-6 pcie slots? It might be releated to these slots being connected to the chipsset? It seems the amdgpu driver needs AtomicOps for OpenCL and these slots don't have these command because of the connection to the chipset? Any suggestions how to get AMS RX 6000 cards working in the higher pcie slots?

Cheers-

To my understanding the fully independent power rail means that you can have individual PSUs per pcie slot (except for slot 1&2 where the power is delivered from the PSU connected to the first 24pin connector). So the power draw on the first 24pin connector would be whatever the chipset, cpu, ram, ssd are drawing plus 2x75W from the pcie slots 1 & 2. The actual draw really depends on the utilisation. My system is drawing about 25W in idle.

The second and third 24pin connector is just giving the power up/down signal to the connected PSU. No power draw via this connector.

Hello fellow miners,

like many of you, I am having also issues with connecting more than 4 GPUs on this motherboard [AsRock H510 Pro BTC+]. Did anyone manage to set up a rig with more than 4 x 3090s on this board?

BIOS updated, PCIs to GEN1 [before only one card was recognized]
Procesor INTEL Core i5 11500, 2700/4600 MHz
Kingston 16GB 3200Mhz
BeQuiet PSU 1500w x2
BeQuiet PSU 850w x2
All cards on risers - 2 on each PSU
Only 4 cards were recognized out of 6 (MSI RTX 3090)
The problem is not in riser, slots, GPUs or power..
To troubleshoot I have connected all cards to PSUs and risers into PCI slots. Motherboard beeps. If I disconnect whatever combination of two cards from PCI slots it loads Win10 and recognized cards, and that is really strange. If anyone was able to connect more than 4 x 3090 would like to know howto :-D
