My cclk is default setting about 800. I want add cclk more around 1500. I do how?

Try MSI Afterburner and increase core clock.

How can I display the individual hashrate of each card?

Hi,

not sure what you mean exactly? If you run TT you should see after some seconds something like this>

06:34:45 GPU[0]: 13.195 MH/s  CClk:1.354 GHz MClk:1.307 GHz 62C 76% 125W 105.56 kH/W [A540:R0 0.0%]  LastShare: 00:00:04
06:34:45 GPU[1]: 12.656 MH/s  CClk:1.759 GHz MClk:3.898 GHz 69C 55% 152W 83.263 kH/W [A482:R0 0.0%]  LastShare: 00:00:04
06:34:45 Rig-Speed[2 min]: 25.851 MH/s 277W 93.323 kH/W [A1022:R0 0.0%] Uptime: 05:04:36  LastShare: 00:00:04
06:34:45 Luck: avg.time per share (424.19 MH @ 25.851 MH/s) 17 secs. passed 4 secs. luck share: 27% session: 99%

The first number after GPU[0] and GPU[1] is the hashrate for that card. Please clarify is this is not what you are locking for.

Thanks.

can you please show me your command line? Let me check if there is an issue - could also be a problem in the miner if the pools uses some command the miner do not know.



Hello, for some reason this miner will not start as it says "connected to pool xxxxxxxxxxxx" and then it says "lost connection to pool xxxxxxxxxxx" over and over and never starts, the same pool works well with a different software

New version 2.2.3 release.

These are the modification - I have had to modify some of the core functions so that they become OS independent. So please check if this version works as expected. If not please reinstall 2.2.2 and report the issues to me so that I can fix them.

- Fixed a file sharing bug.
- Changed Thread-functions to be OS independent.
- Changed File I/O to be OS independent.
- Fixed a the time-interval for updatechecks.
- Shows information how long the Merkle Tree generation took (MTP only).
- Shows the current mining block if the information was available in mining notify.
- Shows optimized grid- and blocksize that is used for the Kernel.
- Add power usage information into API information. Requires Awesome Miner Version 6.3.4 or later.
- ProgPoW: Show when a new algo is created (New Epoch for BCI, otherwise after 50 block).
- ProgPoW: Calculate optimized blocksize for each new algo.
- ProgPoW: Add version used by Zano (Cuda 10.1 only - older cuda versions will follow soon).
- ProgPoW/MTP: Small performance improvements.

Happy mining!



Hi.
Any change on "-b" or "--api-bind" arguments, so it can be accessed from other computer in same network (not just from rig's local computer)?
Thanks.

Thanks for the update.

Any recommended configuration for 1080ti rig? is it better to just run the miner with -i 15 or -i auto 1024 8192 256?

Are you on MTP? To find the best settings I would start without OC and run default intensity. As soon as the hashrate is stable I would increase intensity. Repeat that until you do not see higher hashrates. Then use the best intensity. After that you can play with some OC and see if that have any impact to your system. Sorry that I do not have a more 'concrete' advice, but systems are too different to give general hints that fits all of them.




Thanks for the quick reply, yeah I'm on MTP, just wanted te see if there was a tested base point to start off.

about my other question, which type of intensity would you recommend tu use a) -i 14, b) -i auto 1024 8192 256, c) -gi,gs ?

thanks

I would start without -i. The miner will tell you which default intensity it uses for your gpu. Then wait for a stable hashrate and restart with a higher intensity (-i) until you see that it doesn't rise anymore.

-i auto takes a very long time (and please do not forget to add -log to your command line so that you can see the best settings for your gpu.)

I general I assume that the sweet point is default intensity + 1 or +2 - just in case you want to have a fast result.

progpow-zano is unstable, (2 out of 3 GPUs) and (1 out of 2)will stop mining/crash around 20-30mins

windows 7 64bit, cuda 10.1

Hi,

there was just a new Zano release (daemon/GUI). I just read that there will be new binaries. So please wait until this update is finished and please download TT again and retry. Please add -log -logpool to your commandline to create logfiles. If it crashes again please send me the log - they can help me to find the problem.

Thanks for reporting.

TrailingStop, what about statistic for shares at console - accepted\rejected etc, per device and summary?

Hi,

I'm not sure what you mean with 'shares for console'Huh Here is what you get now:

Can you add some "switches" that can be pressed while miner is running to change for example intensity on go or gridsize or some other things?
To don't have to restart miner.. Smiley

just asking ..  Roll Eyes

Yes, it is already on my list and will come in one of the next releases - some other user already suggested that.

On easy thing that you can do to improve you hashrate quite a lot is to improve the cooling of the GPUs. This can easily bring you additional 5-10% - maybe you already noticed that a cold GPU performs much better than a hot one.

Whilst this is quite common knowledge, I think it only really starts making a difference if your GPU is around 75-80C and above.
Don't think I've actually seen any performance degradation from a few degrees difference while one's cruising under 70 (where most undervolted Pascal cards should sit quite comfortably).

Hi dragonmike,

this is what I'm talking about - maybe that is because I do not really take too much care about the environment. This is my development 1070 in a big tower case - as you can see temp is 67°C and hashrate is around 2.2 MH/s - the miner running up for 60 seconds:

Maybe I should take more care - have Fan on 'auto' in AB.

No this is a fair observation. If you start throttling between 67 and 69C it's definitely more sensitive than other miners/algos so worth pointing out.

I'll try setting a more aggressive fan curve, or pay closer attention to speeds between the cards next time, to see if there's any noticeable differences.

Don't think I've actually seen any performance degradation from a few degrees difference while one's cruising under 70 (where most undervolted Pascal cards should sit quite comfortably).

Hi dragonmike,

this is what I'm talking about - maybe that is because I do not really take too much care about the environment. This is my development 1070 in a big tower case - as you can see temp is 67°C and hashrate is around 2.2 MH/s - the miner running up for 60 seconds:

After some minute the temp is up to 69°C and the hashrate is down to 2.1 MH/s and during the same timeframe the CoreClk is down from more than 1.8 GHz to 1.75GHz:

Maybe I should take more care - have Fan on 'auto' in AB.
