Re: GPU 1 on Gigabyte Motherboard is always generating HW errors

Hello,

I have 5 RX580 8Gb cards under HiveOS.

GPU 1 is always getting HW errors... but the strange thing is that it's happening with any card listed on GPU 1 !



I first thought it came from the card or the riser but I figured out that this is not hardware related problem.

I thought it's the biosmod but I tried with the stock rom and it it does not change anything

I removed the GPU 1 card from the rig and replaced it twice with 2 different GPUs (different risers, power cable...) on the PCI slot. They all got a lot of HW errors…
When they are recognized as GPU 2/3/4/5 they are working without issues.

I also leaved the PCI slot of GPU 1 empty and only pu the cards on the other PCI slots of the motherboard: GPU 0 / GPU 2 / GPU 3 / GPU 4 / GPU 5



But I suppose the computer does assign the PCI slot of GPU 2 (PCIEX1_2) as GPU slot 1. Indeed there are always HW errors indicated in GPU 1…while physically there is nothing on this slot.

I configured the BIOS as indicated in the manufacturer's instructions. (https://www.gigabyte.com/MicroSite/462/mining.html)

I can't figure out what is causing this issue.. ? A BIOS setup? A hardware problem with the motherboard? It's a GA-H110-D3A (Gigabyte). Bios is up to date.

I am using HiveOs and Teamredminer (But also tried under other miner and SimpleminingOs)

Thank you 🙂


Looking at your picture of the mobo with risers it seems you have the first riser in the PCIe 16 slot and not in the PCIEX1_1 slot. The PCIe 16 slot should be empty.
In other words only use PCIEX1_1/2/3/4/5 slots.
Why PCIe 16 slot should be empty?
I had 1 such motherboard and video cards worked fine in various installations. And I also had 5 cards instead of 6, because for 6 cards I needed a more powerful power supply.
