I have noticed a bug with combo ETH Miner v9.8 + AMD Blockchain Aug23 driver.
If miner looses connection to a pool, after reconnection hashrate significially drops.
Restarting the miner solves this problem.
Hasrate before reconnection to pool is ~156MH (26MH x 6 cards) and hashrate after reconnection is ~67MH (7, 11, 11, 7, 11, 18MH).
There was no such a problem with same miner and older drivers.

Claymore, I can send you the log, if it is neccessary.
This problem is still reproducible with CDM v10.0 and the same blockchain driver.
Rigs with 16.7.3 driver works well for 500+ hours.

Normal hashrate:
00:26:41:263   12ac   ETH - Total Speed: 157.527 Mh/s, Total Shares: 269, Rejected: 0, Time: 01:38
00:26:41:278   12ac   ETH: GPU0 26.059 Mh/s, GPU1 26.316 Mh/s, GPU2 26.297 Mh/s, GPU3 26.301 Mh/s, GPU4 26.260 Mh/s, GPU5 26.293 Mh/s
00:26:41:278   12ac    DCR - Total Speed: 4410.745 Mh/s, Total Shares: 810, Rejected: 14
00:26:41:310   12ac    DCR: GPU0 729.664 Mh/s, GPU1 736.848 Mh/s, GPU2 736.329 Mh/s, GPU3 736.429 Mh/s, GPU4 735.283 Mh/s, GPU5 736.192 Mh/s

Then miner looses connection to pool:
00:31:41:744   12ac   Socket was closed remotely (by pool)
00:31:41:744   12ac   ETH: Connection lost, retry in 20 sec...
00:31:42:009   1210   Socket was closed remotely (by pool)
00:31:42:025   1210    DCR: Connection lost, retry in 20 sec...

After reconnection hashrate is ~2x lower:
00:33:03:981   12ac   ETH - Total Speed: 70.921 Mh/s, Total Shares: 293, Rejected: 0, Time: 01:44
00:33:03:997   12ac   ETH: GPU0 16.093 Mh/s, GPU1 11.812 Mh/s, GPU2 11.813 Mh/s, GPU3 11.818 Mh/s, GPU4 11.796 Mh/s, GPU5 7.589 Mh/s
00:33:04:044   12ac    DCR - Total Speed: 1985.794 Mh/s, Total Shares: 855, Rejected: 14
00:33:04:060   12ac    DCR: GPU0 450.611 Mh/s, GPU1 330.748 Mh/s, GPU2 330.755 Mh/s, GPU3 330.902 Mh/s, GPU4 330.287 Mh/s, GPU5 212.491 Mh/s
...
after 9 hours nothing changes, hashrate is still low:
09:09:49:724   12ac   ETH - Total Speed: 72.822 Mh/s, Total Shares: 1865, Rejected: 1, Time: 10:21
09:09:49:724   12ac   ETH: GPU0 19.089 Mh/s, GPU1 10.880 Mh/s, GPU2 11.818 Mh/s, GPU3 11.818 Mh/s, GPU4 11.811 Mh/s, GPU5 7.406 Mh/s
09:09:49:739   12ac    DCR - Total Speed: 2039.024 Mh/s, Total Shares: 4561, Rejected: 71
09:09:49:739   12ac    DCR: GPU0 534.490 Mh/s, GPU1 304.646 Mh/s, GPU2 330.906 Mh/s, GPU3 330.900 Mh/s, GPU4 330.707 Mh/s, GPU5 207.375 Mh/s

Does anyone have the same problem?

Yes I always have the same exact issue, and once the hashrate dropped after losing connection to pool, sometimes your rig will auto-restart or hang in the process of doing so.

When checking log of a rig that's stuck, the last few lines always involve' ''Socket was closed remotely'' and checkread timeout. My rigs are all using ethernet connection and still getting these, maybe it is just the connection in my area.

Hi Claymore

Have you managed to replicate the issue with 12 gpu systems
issue: on version 9.8 if you have more than 3 amd cards in a rig of 11 or 12 gpus ethdcrminer hangs on Algorith ASM, if you start the instance with 3 amd cards and the rest nvidia then it starts mining. then you have to start another instance of ethdcrminer with the remaining cards, .
This issue was also experienced by a youtube channel Cryptomined where he had to have multiple instances on 9.8 running in order to use all the cards.
When all cards are selected after the cmd window hangs nothing but a hard reset solves the hang.
Hope that helps, if you need any more info or troubleshhooting with this regards you can let me know.
thanks
 

I don't have appropriate hardware to test 12GPUs configuration. You can try some different miner to check if it is more stable, because the reason can be not in miner. Also try "-gser 1" or "-gser 2" option.

Hi Claymore can you please tell me what's with checkread timeout that's been happening to some of my rigs inside log. That's usually the last line of message before the whole system reboots itself or hang in a loop required hard restart. Thanks!

Need help on this, happening to a couple rigs of mine. Seems like after checkread timeout the whole rig would reboot itself, that's fine but sometimes the rig just hangs. Anyone please?

Need some help with this error, rig hangs and the log shows it got some 'checkread timeout' before it hangs. Tried searching but nobody ever gave any answer to this.

Weird Timing for Sapphire RX470 8GB w/ Hynix memory
by
cyeedar
on 04/08/2017, 08:01:45 UTC
This is a rx470 8GB mining card (with no ouput) I just bought, the timings from Polaris seems weird, it goes up to 0:2250 and I have never seen timing like this on a 470 be it 4GB or 8GB.

Doesn't it seem contradictory where it was the 0:2250 timing but the max memory frequency is only 2100Mhz?
I copied the timings from 0:1625 all the way to 0:2250 and with vram at 2000Mhz I only get 24.5 Mh.
Can anyone give me any suggestion on how to effectively flash the timings to one that can bring it to around 26-27Mh.
