Good job Claymore team. With 11.5 stale shares reduced from 7% to 3%. After 48 hrs full stable with RX cards.

Update 3 - final one for now

the problem is with the latest amd drivers where in case your rig crashes for some reason, you can't control temp and fan via claymore. For me, it was also causing blue screen on windows 10.

Reverted back to blockchain drivers came in Aug 2017. Fixed the issue.

@Claymore - can you please test the compatibility with latest AMD drivers and fix this in future updates.

Try uninstalling all of the AMD bloat especially Wattman.

I like to have the BIOS flashed with good fam and temp settings.  Then that becomes the default.

The problem is only for Windows 10 1709. Switch to Windows Server 2016 or any Linux distro and you'll be fine.
ETH is still unaffected by this, though - only ETC, because it is few epochs ahead. But ETH should hit the 3GB Windows limit within a month or so. If you still got a problem - try using the iGPU as primary or get another card with more memory as the main one.

This is not true. GTX 1060 with Samsung memory hashes a bit over 25 MH/s at 75 watts power limit? Wasting hashpower?

I have the same problem with dag 176. Yesterdayt it still worked . I use Gigabyte 3Gb with windows 10 version 1709.

what has changed since yesterday?

Hi Claymore,

Have observed the phenomenon happening twice, once after upgrading to v11.3 and the second which is today, 4 days after upgrading to v11.4. I am only mining Ethereum.
The problem is, the Ethermine Dashboard shows miner goes down to 0Mh/s. It show miner has no activity for about 6 hours and then it start to come alive again by itself.
I was not there when the Dashboard displayed miner hashrate activity goes down to 0Mh/s. I also do not have any script file to restart miner if there is a failover or computer reset.
Windows 10 update is disabled. When I came back, I check the logfile for activities on the miner. The logfile does show that miner is alive, receiving new jobs from ethermine pool and mining. Good shares is increasing by the minutes. Another thing I am not sure now is whether the good shares mined are stolen, lost or have they been credited back to my ethereum wallet.

I have tried to post the Dashboard graph here but I cannot and don't know how.

Please check if it is a software bug cos it never happens on the older version before v11.3. My miner are very stable and do not crash. The only time I stop mining is to upgrade AMD drivers or Claymore software.
Hope to hear your reply.

The only thing you can do is just installing the drivers (but then you will have to enable compute mode in registry and/or disable crossfire in registry). Or use DDU to remove everything, make a fresh install and NEVER EVER go in Wattman for any of your cards. I mean don't open it at all or you will be busted again!

I know right? An 8x1060 3gb does 195-200 mh/s and drawing 550 watts measured at the wall.
