Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[Ursul0]

dcri reduced -2 and have almost same speed ETH as 9.1 but lose 10% ot DCR speed. Maybe its more stable i have too random drops -5% on ETH but its good to see we have new version. thanks

apparently v 9.2 gives less stable hash than 9.1 for some of us.
...and I was so proud of myself that I had 9.1 doing more stable than the most people reported, including Claymore

I had not much time for testing due to urgent DCR fix, just noticed slowdown for Polaris on Linux. It is because OpenCL reports that it has 14 compute units (CUs) instead of 36. You can fix it by using undocumented option: specify "-eqlim 288". 288 = CUs * 8. I hate this magic, so I'm working on next update that will have good hashrates with 100% stable mining speed on both Windows and Linux. Just wait a few days.

UBUNTU claymore 9.2!!
speed down !!!!!!!!!!!!!
380x 23 -> 18 MHS

480x 27-> 21 !!!!!!!!!!!!!

Thank you for the update.
Nice work on keeping so many clients updated.

New version is working well for me, even overclocked a bit more than usual so far no incorrect shares...will see how far I can push the threshold- last version at 2225 was good but anything higher resulted in lost shares.

v9.2:

- improved mining speed stability.
- added changes in DCR mining protocol.
- fixed possible issue with rejected DCR shares on Nicehash pool.
- added pool selection in runtime ("e" and "d" keys).
- now if devfee mining fails for a long time, miner will not stop mining, it will turn on "-nofee" option temporarily with appropriate warnings, until successful devfee mining.
- some minor improvements.
- EthMan: added ReasonID parameter to .bat file which is executed when some rig has problems, check "sample.bat" for details.

NOTES:
1. Mining speed stability is better now, but still is not perfect. I'm working on it.
2. DCR: after changes in DCR mining protocol, both pool and mining software must be upgraded. At this moment the miner works with Suprnova, but fails with Nicehash, probably they will update their pool soon. Or may be they applied changes somehow differenty.

Awesome Dev Support Claymore!
Back up and mining..... it is giving slightly lower hashrates... but I'm sure you'll sort that out.
At least we're mining...
Worth your DeVFee!!

Yeep!
Works fine in my 7970 

You should mine EXP instead of ETH.

Thanks Clay, looks like it's working on Windows.
Polaris cards have 32CU no ? 32 + 4 locked

[christiano88]

Now if nicehash would fix up their pool too...would be great.

that does the trick for now. thx

36 CUs in RX480/580, 32 CUs in RX470/570.

thanks it works, bring back speeds:

on ubuntu same settings:
before:
ETH - Total Speed: 23.846 Mh/s, Total Shares: 0, Rejected: 0, Time: 00:00
ETH: GPU0 23.846 Mh/s
 DCR - Total Speed: 929.999 Mh/s, Total Shares: 0, Rejected: 0
 DCR: GPU0 929.999 Mh/s
 
 after with -eqlim:
 ETH - Total Speed: 24.045 Mh/s, Total Shares: 4, Rejected: 0, Time: 00:04
ETH: GPU0 24.045 Mh/s
 DCR - Total Speed: 937.774 Mh/s, Total Shares: 1, Rejected: 0
 DCR: GPU0 937.774 Mh/s

Thanks Claymore,

Well most defiantly down in speed, I calculate by the hour on a spreadsheet.

Previous hour ETC = 0.05729
Last hour ETC = 0.03840

Both ETC + DCR before

ETC @ 60.6MH/s
DCR @ 1760 MH/s

Now ( Best -dcri 27 value I could find )

ETC = 59.5 MH/s
DCR = 1720 MH/s

ethermine.org stats
Average Effective Hashrate = down 3 - 5%

I have more hashrate fluctuations than before on 9.1 I'm not sure why but I did had very few but now I have 4 to 7 times fluctuations in 10 minutes.

will keep working it until I find something that works.

why would you mine ethereum with a 7970.
you can get 280 sols for zcash which is like 400% more profitable.

9.2 claymor now i mine 152 mh ethereum and 4500 mh decret
b4 i mine 168 eth and 2500 decret

how to get back to my old stats?

[molitar]

I was asked to do a test of this miner with nofee.  I can tell you right now you either got a bug in your code or your wrong about 4% less.  It is like 20% less!  The mining speed went down from around 179-183 MH/s down to 142-146 MH/s.   So it either comes to your documentation is wrong or you have totally broken 9.2 to be dropped down by that much.  

[Flickspeed]

I am not observing any speed loss for RX 480 cards on Windows 10 with the new version.

The max speeds are same as on ver 9.1 but they are always at max

So for windows 10 and rx 480 cards this update is working as intended and very well.

I think even the max speed is a bit higher for decred.

-dcri 30 and I ETH speed is almost at max

The documentation is correct, slowdown must be 4%, not 20. Ok I will do some tests to check/confirm it.

[Teress]

With v9.2 my RX480 & 470s have more often hashrate drops ETH mining only and asm 1. From 88.5 to 81, sometimes two times in minute, then few minutes it's ok and then again drops.

[molitar]

Thanks.. I hope we see the next version soon. I noticed a very large drop in performance.

Eth  38 MH/s down to   26.2 MH/s on Coinotron
Eth 184 MH/s down to 140.8 MH/s on Coinotron

I am locked right at 167 MH/s.

My average on Coinotron before was around 203 MH/s so there is definitely a drop in performance. Enough that make a bit more solo mining right now with old version as I have only 1% fee and 1% on pool.  With the loss in hash and 2% miner and the 2 pool fees of 2% it kills profit some.

[coinzoid]

On runtime, we can switch between dual/single coin mining using gpu number. Let's say we are dual mining eth + dcr at daytime, at night we press 0 twice to switch to eth only mining.

Miner, still reports hash rate from DCR although it is disabled. My question is about fees. Does it switch to 1% if we switch to single coin mining on runtime?
