Hello all,


Would have initially said check your page file, but it seems to match your 4x4gb @ 16gb.

I'm thinking here is some sort of BIOS limitation - can I ask what CPU you are using? It's not an APU is it?

There is some sort of bottleneck when you are running more than 2 cards - most of those boards are rated for SLI, but it really depends on the board with anything more than that.

I recommend maybe getting a cheap AM3 board with a Piledriver or maybe an FX6300, should run stable.

It's a AMD Phenom X4 9550, MBO is GA-MA790X, I put latet BIOS.
Maybe it is MBO, my thoughts too I but have to ask and check, it's a bit incovinient to buy new MBO, Proc and RAM.

Grub parameter is already there so it's not that.

Hello all,

I have an "interesting" problem. I have four rx560 4gb GPUs, two XFX and two MSI Aero. XFX are on x16 slots on MBO, MSI on x1, on risers.
The problem is that GPU0 and GPU1 are on 12 MH/s but GPU2 and GPU3 are 5,3 MH/s.
I flashed them with BIOSes from this forum. I tested MSI on WIN10 and it goes for a 14 MH/s and XFX is max 13 MH/s.
Linux Mint, 4.10 kernel, amdgpu-pro.17.40 driver, for a blockchain.
Claymore 10.5, ETH/sia
Two PSU, 400W and 550W, MBO AM2+, quad core proc, 8 GB RAM. There's plenty hdd space, 16gb swap.

Now, the problem is that's too low hashrate on two cards, I don't have an idea how to fix it. I tries some solutions from net but no avail. Commands from claymore seems not working.
Can anyone help me with this? Would it be better if all four GPU are on risers?

I have 3 x1 on MBO and 2 x16, so I am planing for a fifth GPU but...not till I solve this problem.

You are having a 14+ mh/s with XFX rx 560 single fan model? I am thinking to buy 8x XFX rx560 but i was afraid to not to get more than 12 mh/s.

Also anyone tried dual mining with this card?

If you plan to dual mine, I strongly suggest card with additional pci-e power connector and good cooling

XFX rX 560 4gb has an additional power connector, dual mining is 10.5 MH/s // 330 MH/s (ETH/SIA) per GPU, no OC just factory settings

whats the best you can do to a xfx 560 micron single fan?

About 14.8 if card doesn't have additional power connector, 15.5 if it has it.
Everything above 15.5 is just question of cooling memory...gigabyte has advantage that
metal part of cooler covers memory chips too...I don't know about any other card like that, but
if it exists, it should be able to reach 16MH/s too


Which settings should give me that speed on XFX 560 Single Fan with

Memory timings?Clocks?

Thanks.


i have a modded bios for XFX RX 560's that get me a 14.xx stable. You may be able to hit 15.xxx but I could not as the MAX mem clock was 2000 for mine. All of the ones I have are MICRON memory. However even after taking each and tuning them one by one separately. I get weird hashrates i.e 14.xxx on one while another 11.xxx on others. Its strange... not sure what is happening. I normally used the batch file on Claymore to edit the settings/set overclocks/voltage etc. But have been experimenting with using Wattman, and Afterburner.

So far Wattman is okay, but still not even hashrates all around, and AB combined with Claymore is a hit or miss sometimes to have them all at 14.xxx ;

Example: in claymore GPU0 is 11.xxx Mh/s GPU1 is 14.xxx and GPU2 is 11.xxx doesnt make any sense why this is. What I have noticed however is that the DAG file creation time for GPU1 is 8XXX ms vs 11982 ms for the other two. I'm lead to believe the faster the creation of the DAG poch file   = high hash rate.


and these mod values ans straps are:
If you care to share.

I got 12.6-12.7 Mh/s with 1625 straps and 2040 mem and 1150 GPU core clock. Me,ory is micron. Single Fan XFX RX 560.

I also noticed the gpu I have is a downgraded version with 14 CU rather than original 16 CU RX560.

Maybe my values are limit with what I got.

Here is it boys Smiley https://drive.google.com/drive/folders/1DTCpIzPC38v5ShgBu-bFzfciaQXZBxaP?usp=sharing

For u XFX 560 bois

Don't thank me tho, thank the all mighty Branko (I am not worthy), *cough* send him eth for his work *cough*

I apologize for not replying sooner, got diagnosed with severe anxiety and depression but I found the help I need and have faith everything will be ok Smiley

I will try your bios strap settings on my on other cards I'm having problems with. I'm thinking of reverting to the blockchain drivers (beta ones released in Aug) instead of the up to the date Adrenaline (now) drivers.

Thank you, I started to go crazy for a 10.2 MH/s for each card, today I will try it and I hope it will work.
I have a 2 xfx rx 560 4gb, dual mining ETH and SIA (started for testing but now I'm just waiting for a payoff), started to mine one month ago.
Anyhow, you saved me Smiley
