Unusually Low Hash Rate with Gigabyte RX-580's

Hello,

We have several 8 GPU RX580 rigs set up running either ethOS, Simplemining, or HiveOS. Each have their benefits and drawbacks, but if I can get HiveOS to work for me, I would like to move solely to the Hive.

The main issue I am having is with extremely low hashrates with Gigabyte Gaming 8GB RX580’s. I have two identical rigs set up with the same firmware flashed on all cards. The only difference is one is running Simplemining and the other is running HiveOS. With the same clocks (1180 and 2250), pool, miner (claymore in eth only mode) my Simplemining rig is pushing out 31.25 MH/s per card, whereas the HiveOS rig is only pushing ~20.94 MH/s.

Could there be some major step that I am missing here? I like the interface and usability of HiveOS and would like to use it to manage a medium sized deployment, but just need to work out the kinks first.

Thanks

Hi 71MIN3,

I’m facing exactly same problem as you with exactly same card. Do you have Samsung or Hynix memory? In Windows i can get 30MHs, but in HiveOS only 15… Did you managed out what is the problem?

Thanks

Same issue for me and I cant seem to fix it 30 mh/s in windows and 20mh/s on Hive :S

Today i made a new test and when run amdinfo command seems that the GPU and memory are only working as 300MHZ and dont pass this:

=== GPU 0, 01:00.0 /sys/class/drm/card0 ===
Adapter 0: Ellesmere [Radeon RX 470/480/570/580]

The First one is from one RIG that runs RX580 8GB Powercolor (Hynix) and the second is the RIG with problem that runs same boards but with Samsung memory. Core and Mem are stucked at 300Mhz…

Have you got the two vbios that you used to edit the two separate GPU’s? Can you attach them so I can have a look at them to see if there is a variance.


#6

Problem seems to be solved in the new HiveOS Version .30. But now, the OC profile is not getting applied. The boards are running at maximum GPU voltage and even if i apply the profile it does not work.

Here is the vbios of the GPU0 of RIG_02 https://we.tl/FTYOj7d1Ow that i´m facing problems.

I am actually facing the same issue. I have 6 x MSI Radeon RX580 4GB (Hynix memory) that have been flashed.

Running on Windows they get 30-31.5MH/s and on hiveOS they get 23.6MH/s. I don’t know about SMOS, but I think the difference is that on Windows they are using the AMD blockchain drivers and hiveOS is not. Maybe SMOS is using the blockchain drivers for AMD and that’s why you were getting higher hashrates.

I want to use hiveOS but 7-8MH/s x 6 GPU is a huge hit, so I’m (painfully) trying to set up a Windows 10 box. I hate Windows with all my being, but that’s a lot of lost hashes.

Does anyone know if hiveOS is using the AMD blockchain drivers? If not, is that something that will be added (soon)? If not, I’m willing to try and get my hands dirty to add support for them.

This driver question is a good point but I don’t think is the real problem because I have another rig running 6 PowerColor 8GB Hynix memory and working fine using HiveOS and getting 29.8MH/s on all 6 boards. I can’t explain why the second rig is with this issue.


#9

That is strange indeed. It was the only thing I could come up with, at least for my situation anyway. I really like hiveOS and want to use it exclusively, I just need to figure out why my hashrate is so darn low.


#10

Well I was chastised for not knowing that hiveOS is using the blockchain AMD drivers. So I guess my question is why my cards are hashing 7 MH/s slower than Windows.

I’m going to pull the OC settings I’m using in the flashed BIOS on my GPUs and try using Hive to OC and see if for some reason it’s just not using those settings.

I’ll let you know if I find anything out.

For me, the hashrate is not a issue anymore. I am getting 29.8mh/s but the OC is not been applied even is correctly configured. Cards are consuming a lot and generating a lot a heat. In a similar rig with only powercolor rx580 8gb hynix is working fine. But this second rig is not working. I noticed some differences in vbios clock and voltage options but I am not sure if I can modify this info or even try to use the vbios of powercolor hynix because the new ones are Samsung…


#12

Any update on this? I have two Asus RX-580 8gb cards and they’re only getting 21 mh/s.


#13

Всё работает замечательно.

#15

под hive надо немного биос редактировать,и всё будет работать лучше чем под windows


#16

I’m a newbie. Could you elaborate on your the BIOS edits you mentioned? Thanks!
