That got the hashrate up to 28 MH/s but the rig froze after under 10 minutes still. Thanks tho!

Hi everyone,

I have the following rig setup:

Windows 10 Pro - newly installed, fully patched
Control panel performance set to high, never turn off etc
Paging set to 18-20 GB
4GB RAM installed - but tested in 8 GB RAM rig and had same issues
Celeron CPU

3 x MSI Radeon RX 580 GPUs installed. I have tried 2 installed directly onto the motherboard plus 1 riser as well as 1 on motherboard and 2 on riser. It made no difference.

Issue is that if I use AMD's blockchain driver the rig will freeze after running for more than 10 minutes. It doesn't crash it just freezes until I do a hard shut down.

If I install either the latest AMD drivers for the GPUs or an earlier version, the rig stays stable but my hashrates drop from 28.x MH/s to 11-13 MH/s

I also tried 3 different BIOS mods with the same effect.

What is a bit odd is that this rig is about 8 months old - maybe a bit more. It was running fine with all 3 cards then I thought one card was causing an issue so I moved that one card to another machine - it, and this original rig continued to operate fine - till a couple weeks ago.

Any suggestions?

UPDATE:
I have another Windows 10 Pro rig running 2 GPUs. I swapped out the 2 GPUs and tested each of the MSI cards individually. Each GPU caused the computer to freeze after 3-6 minutes of running. The AMD blockchain driver was installed.

Are the cards toast for mining?

April 14/19 UPDATE:
After opening each of the GPUs, cleaning off of the old, dry thermal paste and putting on new....I had the exact same issue as described above.

But then I was watching the fan RPM and they didn't seem to breach the 1300 RPM mark regardless of how hot the GPUs got.  I used MSI Afterburner to spin the fans at about 65% (approx. 2200 RPM) and had no further issues.

So it was definitely related to the GPUs overheating and also to the fans not spinning faster to accommodate the increasing heat.

Thanks for all the responses.

Still no dice but here's an update...I've used the bat file as provided by NumbNuts above this last post (thanks for that by the way!!!) and got the same issue...so maybe this is a network issue?

I tried "weblogin.weblogin" and I also tried some BS entry after -dwal and got the exact same error.  I couldn't use worker.worker as I would need to create a new Suprnova profile unless I misunderstood your suggestion above.

Have you added the environmental variables to the start.bat file as well?  So what I've done in the start.bat (in full):

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal 0x31be6~~~~~~~~~~~~~~8998c6.miner2 -epsw x -dpool dcr.suprnova.cc:3252 -dwal cd$$$ner.cd$$$ner -dpsw x

I should say that Ether is mining just fine.  I can let Claymore run as is all night and Ether will continue to mine with Decred erroring.

Any AV / firewall / router things I should be looking for?  Keep in mind I've added port 3252 to Windows Firewall, disabled Windows Firewall, added rig to router DMZ and disabled AV - all to no avail.

No dice.

Here is the updated start.bat:

EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal 0x31be6e3~~~~~~~~~8998c6.miner2 -epsw x -dcoin dcr -dpool dcr.suprnova.cc:3252 -dwal webloginname.worker1 -dpsw x -allpools 1

My "webloginname" of course matches the username I use for Suprnova and although I previously used Miner1 as my worker name, I changed to worker1/worker2 (intend to run both rigs) but still running into same error as in original post.

What's especially frustrating is that is says that I'm connected to Suprnova but then the pool disconnects me.  Is there anything within Suprnova I need to do other than register an account and create a worker? There is an "x" in the Active column when looking at my configured workers - or is this just a reflection that they're not connecting?

Note - I tried this on another rig - same issues.

Suprnova already has "miner1" as a worker name - and have tried -dpsw x and with specific password as well - no change

Hi all,

I have done quite a lot of research but haven't found a resolution to this problem - hopefully someone can help me on this.

Mining rig:
3 x MSI RX 580 8 GB cards (not Armor/Sapphire etc) - has single 8 pin power connector, single fan, no BIOS switch
Windows 10
SSD with 4 GB RAM
Installed Claymore version 10 Dual miner - Ethereum mining running well and stable but issue is that I cannot get Decred to authorize

Getting:
Socket was closed remotely (by pool)
 DCR: Job timeout, disconnect, retry in 20 sec...

Start.bat command:
EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal 0x31be6e3~~~~~~~~~~~~~~~~~98c6.miner2 -dpool dcr.suprnova.cc:3252 -dwal myloginname.miner1 -dpsw 2222 -allpools 1

Troubleshooting:
- I have changed the password for the worker to match Claymore (x, 2222, other) - unable to leave the password blank for the worker
- verified Suprnova login (though there is an "x" in the active column?)
- attempted both weblogin name as well as email address used for profile
- added port 3252 in Windows firewall for both incoming and outgoing connections
- added miner to router's DMZ
- tried with/without stratum+tcp
- attempted -dpool dcr.suprnova.cc:3252 -dwal suprnova.1 -dpsw x -allpools 1 as detailed on suprnova's website
- though I can't recall which other decred pools I used but all got the same error

Any assistance or suggestions would be greatly appreciated!!
