Miner- Claymore's Zcash Miner

memory speed gives performance not core in my tests…try more with ram not with core …

Hi - since claymore v9.x I’ve had similar issues with random GPUs not being detected, or running at very low hashs. I’ve pulled my hair out, reinstalling drivers, swapping cards, virtual memory settings, checking risers etc.
The low hash rate is temporarily fixed by plugging a monitor into that card. But always another issue on a different card.
I stumbled on a solution by looking at issues for the motherboard as that was my last unknown. Here’s what has worked for me:
In the BIOS go to the PCIe setting and change from Auto to Gen1! That fixed random lost cards and low hash rates! Hope it helps…

you may Try 1366/1950, for sure it will give around 250-260 sols

Thank you I will try

Thank you, I will check the Gen settings on the MB

GEN 1 already selected, and those clock settings crashed my Miner, how do I change the virtual memory?

Right click on "this pc " or “my computer” go to settings/properties – advanced settings – performance-- select custom… and change the virtual memory to above 16gb for multiple gpu rig

I tried to sun new Claymore zcash miner on ethos and after few shares found that problem appears.
Could anyone help me with diagnose? Thank you in advance


You are best off chatting directly with ethOS support following the instructions here ethOS Mining OS

Yes but I run that on Ubuntu and I had the same problem

9.3 is out windows/linux

Have you tested this yet? Any performance increase?

Nice. lets try it out. it says it is not a performance release but can make an performance increase by 1-2%

light improve 6x r9 390 from 1920 to 2000H/s

What is your clock settings for r9 390?

9.3 \ r9 390 \ windows 7 - 307 H/s

Interesting Optiminer has posted he is finalising a release of new miner with much improved speeds

1140/1500 win10 15.12 driver

I see some improvement for R9 390X.

Nothing changed for R9 Fury or RX 480.

I have an R9 290x and an RX 480, and I’m using the most recent catalyst drivers. Yesterday I tried setting up Nicehash to see what I could make with that, but I never made it past the bench-marking phase. The benchmark results for the R9 290x just showed up as “Awaiting Results”.

So I decided to put that on hold for the moment and tried to launch Claymore again to mine Zcash. After a couple of minutes my PC fully shut down, I started it back up, got it mining again, and of course it shut down again. It was late at night so I gave it a break and have just come back to it now.

I started it up against and let it run for a minute. It was running noticeably slower than it should, so I stopped mining and go the log:
