MultiMiner: Any Miner, Any Where, on Any Device (Free, Open Source, Cross Platform)

[ManeBjorn]

Stick with the 13 drivers the new Mantel 14 drivers are causing some degradation in mining performance others are reporting.

nwoolls, Here is my .bat file for my 1x6970 + 3x7970s, the first part to delete BIN was the best thing I discovered on my own. Perfecting these numbers took about a month. I get steady 724k/s per 7970 card with a few HW errors which is worth it IMO. I could lose 100kh/s trying to save that tiny bit of HW error, not worth it. I hope this helps:

So I am trying this again tonight. I have removed all cards except one 7970, and I these are the results I am seeing:

https://www.dropbox.com/s/5o04h1x0v7wx4gf/7970-scrypt-a.png

This is generally the poor performance I see unless I revert to thread concurrency 22400 and GPU threads 1. I'm going to try upgrading AMD drivers next, followed by flashing the BIOS some more.

nevermind i found what was my problem
is something to do with my hub because i plug in directly on the usb cpu and its working fine
sorry to bother you, but thanks

Aye, I was going to say, I haven't been having any issues with mine. 

I use the following config:

Code:

--icarus-options 115200:1:1 --icarus-timing long=90 --set-device antminer:clock=x0981 -S antminer:all

MultiMiner version 2.6.2 is available. This is a bug fix release that addresses issues on some more exotic setups:

• Fixed error launching with Network Device Discovery enabled on Linux - ObjectDisposedException
• Fixed error enabling MultiMiner Remoting on Windows Server 2012 - Null reference
• Fixed error registered instance via MultiMiner Remoting - InvalidOperationException
• Fixed error launching app with no network connection on Linux - SocketException
• Fixed error refreshing statistics from Network Devices - Null reference
• Handling added for displaying Dogecoin information whether DOG or DOGE is used

dont forget win 8.1 network detection!

reproducable everytime!

not a problem with my rig.


i see alot of items fixed up there with net discovery etc. :-)

ok sorry i wont bring this up again :-)

its real.

I understand, but I have tested it and I am not able to reproduce a BSOD when mining on 8.1 without a network connection. You have also posted in this thread at least once before that about receiving BSODs after mining for extended periods.

BSODs are not caused by user space software like MultiMiner. They are caused by hardware or kernel space drivers. If you want to troubleshoot any of the BSODs you are encountering there are steps on Google for doing so, e.g.:

The VDDC on your card looks low, is it lacking voltage? Also 1080 GPU clock isn't prime for all 7970s or R9-280s, try 1000 or 1040. That can make a pretty significant difference. Your memory clock is also running at a weird frequency, it should be 1500. If the clocks deviate enough it will wreck your performance. The g1 config you have may just work well with the above settings.

nwoolls, update on 2.6.2 - First I should not I am not at the shop so can't copy paste the error until later, but I will explain what triggers and that it doesn't actually crash but errors every few minutes.  This started randomly I walked in and logged in and was owned then kept trying, remove (I use exe install type), delete all appdata, etc. so I was a fresh start.  Same thing.

When I enable donations and remote miner, then hit ok and goes back to the main UI I get an error message almost like what that guy a page back had.  Though mine was about duplicate port errors I turned everything else off that calls out on a different port possibly (stratum proxy is disabled).  It worked on the original 2.6.0 but I didnt do 2.6.1 so when I installed 2.6.2 it just started randomly doing it.

Now I need to turn off remote miner (even though I had it enabled before) and see if it still causes it and get you an error message because you maybe will understand that more than me LOL!  It's early!

Server: i5-4720K, 16gigs, Windows Server 2008 R2, One NIC for outbound traffic, One NIC for local network only (stupid U-verse "sticky" IP stuff).  No IIS, DNS, etc. ran from the box it literally right now is only Multiminer LOL.

In the future will you possibly be adding an option to rename the network devices (I only tinkered with them some so if there is a way just tell me page number to read LOL).  Like I have 4 Antminers now and 10 more on the way and yes everyone is labeled on the miner itself but think it will look better than the list of the IPs esp since i have 4 Avalons and probably a few more things here soon.  Also with API commands can I push out pool information to make it swap pools, I honestly can't remember.

Thanks man!

Great stuff, ill try this later

I haven't touched the VDCC but I tried all sorts of clock rates and memory speeds around those. I started at 1000 and 1450 and ended up with those in the screenshot. The hash-rates in the screenshot were the max of what I reached. So running the mem at 1500 or the core at 1040 didn't help.

I appreciate the details but really need the error logs to diagnose and fix the issue. If you can get those to me I will fix it ASAP. I have a 2.6.3 build already in the works with some fixes.

Thank you - both of these items are planned for the Network Devices feature in MultiMiner: both renaming devices and actually sending API commands to them.

Your baseline for any testing should be 1000-1040 engine and 1500 mem. I would lock engine in that range, mem you can try increasing to 1550 to see if it helps, I had one Sapphire 7970 that I needed to do that for.

I've had my sapphire 7970's need anywhere from 1070 to 1150 VDDC, varying by card.

But as I wrote in PM, you need to try one of those cards in another system. I do have an old XFX black edition 7970 that I run better at G1, with some unique settings, but never my Sapphire 7970s.

For that XFX card I run:

VDDC: 1175
Power: +20
Core: 1065
Mem: 1880
Mem Volts: 1600

With BFGminer switches: --intensity 20 --temp-target 75  --thread-concurrency 24000 --worksize 256 -g 1 --auto-fan 

This gets me 720 on the card. I hadn't encountered a more difficult card to figure out, and I couldn't get it to co-exist with other 7970's, so I run it with another 7950.

Thanks for your reply and your PM. To confirm it is 2 separate cards acting like this. I also don't really have another system to try unfortunately. My other PC is a Mac Pro  I guess I could build up another but I'd like that to be a last resort.

Some hardware info:

Code:

Gigabyte GA-970A-D3 AM3+
AMD Sempron 145
Corsair XMS3 4 GB
Silverstone ST1500 1500W

I definitely get what you guys are saying about the core speed, but please don't dwell on the screenshot too long. I will take your advise and stick around 1040 and try upping the memory speed instead. Most of my testing was from 1000 to 1040. I only pushed further when I wasn't getting improvements.

You dont have the same parameters as I posted. Keep TC at 8128 and try

--gpu-engine 1060 --gpu-memclock 1450 - D

and let us know what you get please. Im curious.

nwoolls, here is a funny request, when the strategy kicks in to switch a coin, can you make the cards switch one at a time like on a 30 second stagger? Its a funny request but I think that way the noise change from the fans would be less noticeable. I had the rig running last night on 15min intervals and I was sleeping in the same room, I think I woke up a lot. I was so tired in the morning as if I had not slept much. During the day my wife was at home and she complained about the same noise issue. I know it doesnt happen when the same coin is still the best to be mined but still happens often.

Also an option to always mine the top two coins only would be great too. Here is why, coinchoose shows litecoin as #3 right now and that is so wrong, litecoin is like the 15th or lower rate coin on coinwarz all the time.

BUMP.

@ nwoolls, did you see this post?

[nwoolls]

nwoolls, here is a funny request, when the strategy kicks in to switch a coin, can you make the cards switch one at a time like on a 30 second stagger?

No this is not possible without launching each of the cards in their own instance of bfgminer which would add complexity and performance overhead.

Instead I'd recommend using a standalone program like MSI Afterburner to set the fan speed. That way the speed is constant.

Also an option to always mine the top two coins only would be great too. Here is why, coinchoose shows litecoin as #3 right now and that is so wrong, litecoin is like the 15th or lower rate coin on coinwarz all the time.

Here's some stats from tweaking. This is in line with what I've seen in the past trying to tweak these 7970s:

Gonna keep poking things, maybe trying another BIOS.

I had tried everyone recommended settings included yours. The screenshot was best-case. Your settings get me about 400 Kh/s.

Check my previous post for a chart showing some of the combinations I've tried.

I am having problems with the mutiminer and hoping that someone can help me out.

I ran multiminer for at least a week or so with no issues. This software is the best.

When I was using the multiminer, I clicked on one of the links in the miner that said there was a new version. I got an error message after that, but do not recall the error message. I could not get it to work, so I turned the computer off and decided to resolve the issue the next night.

I get home tonight, download the newest version of the software and I am having the same issue.


I am running my video card to mine dogecoin and have an erupter and a USB antminer that mines bitcoin.

When I start multiminer, it recognizes all three items, but simply does not start working. I get the message on multiminer that says "Not Responding".


While I was typing this, an error for Microsoft Net (or something popped up). I copied the error below, but have no idea what it means.


Should I just uninstall the software and download it again? Or does the error message below tell me anything?

Sorry for the long post, but thank you for the help.


See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Did you try rebooting the system then restart?
I had to do that after the last upgrade and no issues since.

Worst-case, you should be able to delete and re-install it.  Delete both directories in Local\MultiMiner and Roaming\MultiMiner and reinstall.

I do have an old XFX black edition 7970 that I run better at G1, with some unique settings, but never my Sapphire 7970s.

For that XFX card I run:

VDDC: 1175
Power: +20
Core: 1065
Mem: 1880
Mem Volts: 1600

This absolutely got me going in the right direction. I had to get a BIOS flashed on there that would allow me to clock the memory over 1600. Once I got the memory at-or-over 1700 things started looking great.

Thank you all very much! This will absolutely help me test some new scrypt enhancements I am doing for bfgminer.
