Topic: Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux) - page 146. (Read 3839201 times)

Actually Claymore specifically states that it takes 3000 rounds (his words) to get an accurate hash rate. I believe the miner states that in the log, when the miner first starts.

sudo apt install -t jessie-backports fglrx-driver=1:15.12-2~bpo8+3

Can someone give me link to 15.12 drivers, cant find them online. AMD page is super not user friendly when searching for old drivers. thx

Also what drivers give best results for R9 390s?

Can I mine dash with claymore? how ? I have 7990 and 280x some help will be appreciate!!!

anyone notice that 390x show 500 hs for the first 30 sec then it steadily drops.  12.1.  Is that potential or just that the rounds havent avg out.  Most of time it started way short and worked its way up not other way around.. Just wondering


Edit for what its worth it does it on all cards.  even 290x shows 450 h/s

I removed a card from the system today and it crashed with 12.1.  I'm going all the way back to 9.2 now to see how it does.  I'm still thinking this is a power supply issue.

9.2 was the last version I was on before I went up to 12.1.  I was also running 3 video cards for the majority of the time on 9.2 but I did run 4 cards with no issues for nearly a week before I started having reboot issues which is when I started looking to see if there were newer versions of the miner that might 'help'.  Foolish of me... this is looking more and more like a power supply problem.  Now I'm seeing people say they try to stay around 70% of what' their power supply is rated.  With 3 cards on 12.1 I was seeing around 560 Watts at the wall which is close to that 70% range some others were saying they spec for.  Hoping I can get a 1200 Watt gold PSU in a few months and then be back up to full speed.  ugh patience is not my strength ><

Edit:  crossing my fingers this will solve some problems:   I just ordered this thing:  http://www.parallelminer.com/product/gpu-mining-power-supply-kit-hp-1200-watt-80-gold/   

Put the miner on local proxy and see what it shows about shares/speed.

If you have the option, you could move a card off that rig and see if stability returns. Just a thought.

Anyone else notice that v12/12.1 is reporting about a 5% higher hashrate than pool(flypool) for polaris based cards?

For example a 470 is reporting 280H/s miner side, and 260H/s poolside average. With 2% fee should be reporting ~275H/s.

Can anyone else on flypool with polaris cards confirm...want to see if its just me or a pool related issue.

Best is to mine @60-70 % of PSU power. There is max eff. Also ZEC mining demands stable PSU, there are power spikes demanding large 12V output electrolyths
