Rig stopped reporting temp and fan stats when I unplugged monitor and connected remote.  Has anyone else had this issue?  Is there a workaround?

Firstly, big thanks to Claymore for getting this great miner out to everyone!  I know you mentioned that you still expect you can get better rates down the road but I think I am not alone in appreciation for you publishing this version now so we can mine more efficiently than other options currently available!

I have only read about half of this thread so sorry if I am repeating anything here but I did have a few observations and questions that I wanted to post.

- I have 4 MSI RX 470 4GB (strap 1500 mod, overclocked, undervolted) averaging between 40-42 Sols/s each using your miner. This is a vast improvement over the 13 I was getting using nicehash the last few days, so really appreciate the extra sols!

- I noticed that the power draw for this miner is much lower than your ETH Dual Miner.  Even just solo mining ETH my rig was using ~625W at the wall, while your ZEC miner is only using between 400-450W!  This of course increased the profit margin over ETH mining even more, which is great, but I have a question about the power consumption.  Is it just that mining this coin is inherently less power-consuming than ETH?  Or, does the much lower power draw mean that there is still a lot more headroom to work towards increasing Sols/s even more?

- Finally, after running your ZEC miner stably for about an hour this morning, I launched nicehash miner to use only its CPU ZEC mining function. Unfortunately, almost right at launch, it cut the Sols/s rate in your miner by about 25% on each GPU.  Then after about 5 minutes, it crashed my system. Then crashed again after reboot, so I haven't tried it again.  This seems a bit weird to me since I have used other CPU/memory intensive programs like Claymore Crytponote CPU to mine XMR and plotting & optimizing BurstCoin plots on HDDs and neither affected your ETH GPU miner.

Normally, I wouldn't even bother about CPU but this rig has an i7-6800k that was pulling 23 S/s, which equates to more than half of a GPU, so I hate to waste it idly.  Anyone here been able to CPU mine ZEC with NH and GPU with Claymore successfully?

Did you set your nicehash miner using -t 6 ? (6 = 6 threads)

Nope... thanks, I will give that a try and see what happens.  Out of curiosity, how exactly would you do that?  I know how to make that kind of change like in a .bat file (such as exists in Claymore's work) but I only see EXE and DLL files in the NHM directory.

Remote Desktop you mean? RDP sessions are known to disable GPUs, that's why I'm asking.

Yes, RDP but its mining with no issues, just not displaying temp and fan stats.  No changes to config made when i unplugged monitor and connected remote. 2 x r9 290.

Works amazing! thanks

STOP The thanks! You are making the thread going fast, unusable for support question and impossible to follow, even claympre wont be able to follow it. Just use it for problems, advises and suggestions!

Thanks for posting this.  And thank you Claymore!

If you disconnect the monitor while mining and connect using RDP, the miner will continue to mine but the sensors will be disabled first. If you stop the miner and try to restart it again, the GPUs will no longer be detected. This problem frustrated me for weeks until I figure it out and started using other methods of remote screen control. Try VNC, Teamviewer, Logmein etc...

Or try using 3rd party app like GPU Z? might be useful especially when looking power draws and gpu loads

I am pretty sure its the pools you guys are using not the miner. I am using flypool and have been running claymore stable since he released it. All the complaints about an unstable miner seemed to be linked to an unstable pool. Please read the forums on zcash to determine which pool is the most stable because its annoying to keep reading these individuals problems......

Couldn't have put it better myself

Ive actually restarted the rig with RDP several times and it mines with no issues.  You think if I use something else to connect like NVC those stats might work again?

i7 3770 and 1x amd fury almost 11 hours stable now.. -t 6 ..win7 x64, 16.10.3 driver

~19 sols on cpu ~ 50 sols on gpu

You're using Nicehash for your ZEC CPU mining?

yes. nheqminer_v0.4b version

use the nheqminer.exe github download link at nicehash "getting started" page

nheqminer.exe -l stratum.zcash.nicehash.com:3357 -u zcashwalletaddress -p x -t 6

OK... thanks to all that have replied with help on this issue... I really appreciate it!  I have downloaded v0.4b as mentioned above and later linked by mike.  I created a text file with the exact line above and saved as a text file in the main directory.  I think I can figure out how to convert it to a .bat file, but I have a question about the "zcashwalletaddress" part.  In using the NH GUI to CPU mine on my 2 other PCs, its converting my mined ZEC directly to BTC and sending to my Coinbase account.  I would prefer to keep this intact, if possible, using this stand-alone non-GUI nheqminer.  To accomplish this, can I simply paste my BTCwalletaddress in place of the zcash in the line above?  Or, is this "selling hashing power" functionality only available if the NH GUI is used?

It may be interesting to note that 1 GB cards CAN run stable using Claymore's miner here insofar as long as you have another card that has more than 1 GB available and is the primary card.

I've tested this miner with a Radeon 7770, these are the results:

Solo instance:
9 sol/s, however miner will either fail to call OpenCL properly immediately or error out after about ten minutes.

Dual GPU with Rx470:
GPU 0 Rx470: Stable at 10 sol/s for 4 hours, moved to Rx480 for further testing.
GPU 0 7770: 9 sol/s, however miner will either fail to call OpenCL properly immediately or error out after about ten minutes.

Dual GPU with Rx480:
GPU 0 Rx480: Stable at 10 sol/s for 2 hours and counting.
GPU 0 7770: 9 sol/s, however miner will either fail to call OpenCL properly immediately or error out after about ten minutes.

I will update this post as I accumulate more data. I like to test low-end spectrums so even those without access to the resources to afford a "good" GPU still have an option.

Great job here, Claymore. I look forward to seeing what your future updates improve on!

Yes. GPUZ sensors stop reporting in an RDP session, which is another indication the sensors are off.

In case anyone wants to know what 6 280x hash.
It floats around 245 to 265 H/s stock settings.

Its reducilous that a two generation old card is faster than the Rx cards

the RX cards should be getting at least 60 SOLS

Haha yea man I feel your pain. These 280Xs are absolute beasts. I adjusted all the cards to run at 1150MHz freq and they are pushing around 300H/s! These cards are absolute monsters for Zcash.

Kudos to you Claymore.  Gladly pay the 2.5% for a 35% speed increase.
Used your miner for ETH when it was worth it.  Spend my fee wisely.

You ROCK MAN!! You answered my headache in finding good miner.. Thanks Clay!
