H510 PRO BTC+

I think something strange is happening. I only have these options in advanced menu of BIOS:
- CPU Configuration
- chipset configuration
- storage configuration
- super OI configuration
- ACPI configuration
- USB configuration
- trusted computing
Just when i put the second GPU My system is going to sleep, I can see both cards are powered, the fans are working.
I am out of ideas what is the problem exactly

So, to let you know, after testing everything, the solution for me was this : usafmike76 wrote: Hey did you try to adjust the C.A.M. (clever access memory) in the BIOS, Advanced, Chipset Configuratio? I updated my BIOS to the current one and when I booted into Hive i was only seeing 1 GPU. I changed some of the PCIE settings but nothing worked. So i put them back in Auto and changed the C.A.M. Activating C.A.M on BIOS was the only working solution. BTW the 5 beeps error is indeed caused by no monitor plugged to 1st card (or what ever you set BIOS for). I have 4gb RAM (so 8 isn't mandatory), I didn't even update BIOS to 1.30 (I don't use 30 NVIDIA series) and I'm on HiveOS, mining Ethereum on NBMiner. Thanks everyone for the help, I hope this post will also help other people because vanishing after solving problems doesn't help communities ;)

2 cards was easy. how about 5 or 6?

Hello!

I have the same problem as several people. Black screen.
I changed the ram memory, processor, I've done a test with the GPU connected, disconnected and nothing...
I've already tested another HDMI cable.
No beeps.
No image.
No lights on keyboard. If I plug in a GPU, its fans start spinning and stop when I turn on the mobo.

Hi everyone,

I have 3 of those motherboards and looks like I really need some help with it. I tried everything and going nowhere. Here is how it looks like.

MB #1 - working just fine with 6 GPUs, 3060 Ti, i3 10100F CPU, 8MB RAM and 2 Chieftec 700W PSUs. For some time I even managed to plug 7th GPU through mining port. Everything worked well so I bought 2 more H510+. Now the magic begins...

MB #2 - working with 2 GPUs, also 3060 Ti, same PSUs, 8 MB RAM, CPU is Celeron G5905 this time. It is on MB support list etc. Done everything by the book. Updated BIOS, installed all drivers, molex power supply connected according to previous posts. BIOS settings same as in MB #1 which is working. Can't get more than 2 GPUs working.
MB #3 - not working at all. Same components as in MB #2 but the only thing I get is 5 beeps after start and black screen. HDMI connected to GPU. GPU tested and working, tried other CPU, RAM, done CMOS reset, checked if the CPU is installed right twice. Nothing works. 8 pin CPU cable connected. CPU and GPU fan are spinning but apart from 5 beeps that is all.

I don't know what to do anymore. Please help.
