Guys,
I'm running a 10 cards rig 8*RX580-4G + 2*RX570-8G + RX480 @ core/mem 1200/2000, 1750 strips. Right now I'm using SimpleMining OS. Had no issues when mining with XMR-STAK, but after changed to claymore v10.2; with these settings, I start noticing rig freezes and miner reboots.
Noticed that by deafault, Claymore V10.2 was passaing the -h 900 & -h 1800 to the 4G and 8G cards respectively. I've downgraded the "-h" parameter to 850 & 1700 respectively @ core/mem 1200/1900 , and it seems to do the trick.
Question, what the heck is the -h? and what it does precisely?
Another question... if I want to configure the failover in SimleMining, whats the path to upload the epools.txt file? anyone knows?
Best.
I'm using Simplemining OS as well and have issues with the miner constantly freezing and reboot. The other issue I get is the miner will restart but the initializing will fail and the miner will be stuck at mining 0H/s.
I've never played with the -h value. On page 1 it says -h deals with # of hashes that the GPU processes so it probably has to do with how intense you run the cards. I'm going to play with this as well and see how it changes. Sucks that you had to downgrade the cards to 1200/1900, I would have hoped that you can at least run at 2000 mem speed. Have you tried to play with the voltage levels?
What do you have your -allpools set to? Right now my settings are this:
-wd 1 -r 0 -xpool stratum+ssl://cryptonight.usa.nicehash.com:33355 -xwal [yourwallet].$rigName -xpsw x -allpools 0
I'm running RX570 4G at 1150/1750/1000mV and RX580 8G at 1200/2050/1000mV.
I had that behaviour when moved to claymore v10.2 but, to be honnest I had a superior speed with it. Like you, sometimes the miner restart and stay freezed at 0H/s as well. The only way of getting out of this state was rebooting the whole rig. And by rebooting, i mean shutting it off, wait 2-3s in power-off and then rebooting. Lowering the "-h" parameter bring more stability to the system. So, my current onfiguration is:
Cards: RX580-4G,RX580-4G,RX580-4G,RX570-8G,RX570-8G,RX580-4G,RX580-4G,RX580-4G,RX580-4G,RX480-4G
Claymore command line to XMR mining:
-xpool stratum+ssl://xmr-eu1.nanopool.org:14433 -xwal XMR_ADDRESS/$rigName/
[email protected] -xpsw x -mport -3333 -h 850,850,850,1700,1700,850,850,850,850,850
As you can see, you can pass to the miner a comma separated values in that each one is to a specific card from my list above. For reference, the default "-h" value for the 4Gigs cards is "900" and "1800" for the 8Gigs.
My current frequencies for each card are:
CORE: 1200,1200,1200,1200,1200,1200,1200,1200,1200,1200
MEM: 2000,2000,2000,1900,1900,2000,2000,2000,2000,2000
XMR - Total Speed: 6948 H/s, Total Shares: 1340, Rejected: 0, Time: 06:43 |
XMR: GPU0 715 H/s, GPU1 715 H/s, GPU2 715 H/s, GPU3 686 H/s, GPU4 649 H/s, GPU5 712 H/s, GPU6 715 H/s, GPU7 713 H/s, GPU8 713 H/|
s, GPU9 615 H/s
Hope this help
Can anyone confirm what's the "-h" is doing behind the scenes? and why lowering it a bit bring more stability?
