The answer is how long do you mine SIA on nanopool :-)

This was an issue with the pool that stopped/delayed responding to network requests. Miner probably had no explicit timeout check and decided that some execution thread was abnormally stopped. So it had to restart. On Windows some network errors detected much sooner (and as a side effect, Windows loses TCP connections instead of trying to wait a bit and recover). On Linux such connections still trying to recover for some time that exceed miner thread execution watchdog timeout. So there was no issue on Windows machines (miners just reconnected), but Linux miners aborted and restarted until pool recovered.

This definitely needs a fix because any network issue with the secondary coin pool should not abort mining the primary coin.

Yeah, as always, same code works in windows but fails in linux under some circumstances.
I will update linux version as soon as I can build it. My linux system decided not to load for some reason and now I have to reinstall it and all software, it takes some time. Nice OS.

how does gpu instability manifests it self while mining? While gaming, we are presented with artifacts or even crashes. But how does the miner behave?

Usually either CDM detects invalid ETH share by itself and does not send it to pool (number of such shares is shown in console miner stats). Or if something was really bad then OpenCL call (to GPU processors) hangs, miner detects this and restarts itself (or reboots the system depending on -r parameter).

Sorry,
Why no boost on hashrate at 5.0ver by expanse mining?
On 4.7 it was about 68mh/s (2x 280x and 370)
Now it's equal to ethereum...

It works.. A little less 59mh/s instead of 68mh/s in dual mining...

The reaseon was... I have bad port 8008 instead of 8018 in my epools.text 0.o
I don't know why but somehow it was ...
(It works good with 4.7..
I have to investigate Cheesy

Does the effective hashrate drops due to retrying the calculations?
Is there any sort of verification checking for computation errors?

I suppose the wisest thing to do is to check your undervolting with an error detecting benchmark (such as occt).

@Claymore

Hey, played around with it. -gser 2 did not make a difference, but if I removed SIA minning and it works. Is there anyway to make both work?

On eth it is running no problems.

Thanks
-Art

I already told you all my thoughts.

@Claymore
EDIT:
Got it to work with lower SIA mining intensity. My guess is the cards wanted more power than the 2 x 8-pin connectors can provide mining both.

Thanks for the help, keep up that hard work.

You really need to have separate cables from psu to those 8-pin connectors if you are pushing that card. Otherwise you end up with melted connectors.

That is a good idea, i should have thought of that.

Thank you

Anybody has hasrates for older cards? 6970/6990 for SIA only mode?

Any chances for dualmining with NeoScrypt?

I don't think it's really possible. NeoScrypt is both compute and memory intensive.

Is it possible use the new Open Public Pool Siamining for SIA on Claymore's Dual ?

Thank you for hint, just switched to it to test.
Connection params are the same as for nanopool, just replace host name.

Blockchain Just Entered The Real World

Is it possible use the new Open Public Pool Siamining for SIA on Claymore's Dual ?

This are the pool detail:

Pay-Per-Share - 3% fee.
Long Polling support - Minimize those stale shares!
Variable Difficulty - Improves network efficiency and provides more accurate miner statistics.
No Account setup - Simply use your wallet address as the username for easy payouts.
Worker Support - Detailed statistics of each worker.
Quick Payouts - Payments every 6 hours, with a low threshold of 2000 SC. No waiting on block confirmations!

added a few logs, put them in a zip
http://www.filedropper.com/claymoreslogs
let me know if you find something..
CPu: Intel Celeron Dual-Core G1840

It looks like this issue is related to Linux version only. Pool does not answer for http request for >2 minutes and watchdog restarts miner. I can send you an update for tests with enabled http timeout, it must help. Send me PM if you want to test.

Send me full log. Looks like a bug in miner but noone wants to send complete log so I cannot catch it. Also let me know what CPU you use.

Yes, I had this on Linux too.

I was unable to send you FULL logs since I run diskless and before reboot my script saves only last 50 lines of log, and the rest in RAM was discarded on reboot. Anyway, I was sure that it is a network bug, so you are able to find it without full logs.

As I wrote, it was an issue with pool (confirmed by pool operators), and it is definitely the bug in miner. But it did not bother me a lot (just once), so I did not enable logs after that (it was not repeated either).

I am also able to test it, but I think it will be difficult to reproduce. So just add a timeout and hope it will be resolved.

have anyone got Sia-UI-win32-x64 to work?
been on for over 12h now and still loading

It took my wallet almost 48 Hours to sync.

thx ok that was slow. i'll wait more then

If you go to the overview screen it will tell you the block your sync is on.

Current block is Block Height: 59855

This is something else, but I keep getting this unsupported overdrive version error messages in the log with 3x 480x, they are mining nicely tho, it's just annoying,
what can this be?

Added to OP:

- Temperature/fan management for RX 480 is not supported currently. 480 card uses Overdrive v7, latest ADK SDK (v9) supports Overdrive v6, so currently AMD has no public documents about Overdrive v7 and therefore there is no way to manage temperature/fans/clocks of 480 cards.

I see, I noticed with this cards the miner does not show the temperatures and fan percentage, this is the reason then. Thanks.
