GekkoScience Terminus R808 Miner Official Support Thread

[sunk818]

Is anyone having cgminer 4.10 cpu load go way up? If I leave it on for 12 hours or more, CPU pegs at 75%. I have 10 2Pac Gekko & 1 Terminus R808 running.

Going back to Apr 2017 version of cgminer 4.10 I don't have this issue. Memory leak perhaps? At least with Apr 2017, I can run it reliably for many days. Only problem is that if Terminus goes Zombie, I have to restart it manually. Trade offs.

Going to guess you are running on windows?

I run 4 CGMiner windows (latest build) with different groups of USB sticks/pods so I can monitor them as workers with Slushpool.
About 2k memory per instance and 00-04% CPU load each, running on Server 2008R2. I do have a schedule batch file to kill all CGMiners and restart every hour though so not the best "always on" candidate here. The restart fixes the random USB stick that might have quit working.

You are running the same as me minus 1 pod. I have 10 x 2pac and 2 x Terminus.
Let me know if you want me to help with the batch files for killing / restarting.

[mwin58747]

How would I run multiple Terminus R808 using the one power supply?

You would need a breakout board and 6pin to 6pin power cables. one 750 watt power supply would be enough to run around 10 - 11 Pods around 225Mhz (60 watts each)

can i get any server psu with any breakout board?

Windows 10 64-bit Home.

I've used shares before to quit cgminer in a batch file and loop it to restart after it quits. Say 500,000 acceptable shares then timeout for 300 seconds then start again.

--shares <arg>      Quit after mining N shares (default: unlimited)

I have a lot of respect for what @sidehack and @vh do. It is almost magic to me what they can do in terms of hardware and driver/cgminer software programming. I'm just guessing it is some sort of memory or CPU load issue and haven't fully isolated it. Just asking if anyone here has experienced the same. If so, it is worth investigating and isolating so we can report it for a solution. The workaround of restarting is not a bad hack, but it isn't a good long-term solution.

[minerbobbert]

I bet if you only run 2 you'll get the full hashrate out of 'em. Could be a USB traffic limitation, same as several other people are running into.

Just a question I've been thinking about.  Would increasing the suggest-diff setting alleviate some of the USB traffic limitations? I was just thinking, why does everyone it seems, that have posted so far, been running with really low diff? I generally run my 2pacs at 512 aiming for 2-3 Accepteds per minute, or am I doing it wrong.

This is a really interesting question. For solo mining, it wouldn't even make a difference. I use ck's pools, and his pool automatically adjusts the difficulty to match the miner. Whether that impacts shares is the larger question. The USB limit is my main issue now. If this is a good workaround I'd love to know.

[sidehack]

I don't think suggest-diff will have any effect on traffic between cgminer and the miner itself. That only changes the threshold for returned shares to the pool.

as long as you make sure the break out board works with the power supply you choose (THEY HAVE TO MATCH).
I usually recommend complete kits, you know they are paired correctly.

This one is a 750w power supply, break out board and 10 power cables.

[sidehack]

Yes, it's a hardware issue and needs warranty repair.

Speaking of which, everyone who's sent pods back for repair, they're fixed and being tested and will be return-shipped no later than Friday.

Question (or request) for VH on the Gekko build...is it possible to pass in GSD for 2pac's, and GSE for pods to the --USB startup argument? I'm trying to keep multiple instances of cgminer stable and isolate the devices in bunches.

On may batch files, I'm thinking it would be something like cgminer.exe --usb GSD:4 for one instance of 4 x 2pacs, and cgminer.exe --usb GSE:4 in another instance for 4 pods. How are others separating out their Gekko devices on the same Windows OS?

can you share your bat file config that does this restart when it completes say 500,000 shares?

So, I got my 2 pods a while ago, and they were running fun until just recently.  Now they don't seem to run for more than 12 hours.  It appears Rasbian itself is crapping out.  I left an ssh session logged in while I was at work today to attempt to catch what happens, and this is what I saw when I came home.

I've checked to make sure I have the latest drivers, and everything claims it's up to date.  I'm going to try to narrow this down by going back down to stock clock, although I'm only at 175 right now, so it's not that far above stock.  Also going to try one pod at a time.  Anybody else seen anything like this?

[sidehack]

Yep, my test setups drop out a lot with the same type errors. Kinda surprised me the first time, since I had one pod running on a clean build for a couple weeks without any trouble.

[vh]

I've been hearing this creep up more on the Pi.

For now set this option on if you spot kernel messages floating around:
https://bitcointalk.org/index.php?topic=494625.msg5932931#msg5932931

Every case mentioned so far has been solved by that.

Meanwhile, I'll see if I can recreate and trace it.

Question (or request) for VH on the Gekko build...is it possible to pass in GSD for 2pac's, and GSE for pods to the --USB startup argument? I'm trying to keep multiple instances of cgminer stable and isolate the devices in bunches.

On may batch files, I'm thinking it would be something like cgminer.exe --usb GSD:4 for one instance of 4 x 2pacs, and cgminer.exe --usb GSE:4 in another instance for 4 pods. How are others separating out their Gekko devices on the same Windows OS?

That would be interesting, but no it's not available.

In general, it would be best while testing and tuning to focus on a single unit in its own isolated environment.   You'll make better progress and get more repeatable results.

Thanks for the reply, vh. For the life of me I cannot get the 2pac's and pods to run in the same instance of cgminer, hence the question. I'm curious to know if others have been using the latest 4.10 gekko build for both sticks and pods. I can run an earlier build for just the sticks with no issues, but when I add the pods the 2pacs always zombie out.

[QuarterMaster]

Somebody had asked how to set up more than one Terminus on a single power supply. Here is a pic of mine running on a 200 watt adjustable supply using the PCIe connectors (very solid connection). Testing with a small fan mounted over the Regulator on the right one to keep it cool.
237.50Mhz / 98-103GH/s each.

Ok, new issue.  cgminer crashed out with this error report.

Failed to create restart thread errno=12 in cgminer.c restart_threads():5063

One of my pods appears to restart a great deal, even at stock speeds.  It was up to being the 229th device in cgminer.  The rest were still 0 through 6.

It's unhealthy for that number to continually climb.   
The system will eventually prevent new resources from being allocated..

Get the other devices going in its own cgminer with command line option --usb :1, (or total devices - 1) while you work on that last one.
   
As i mentioned a couple of post back, it would be better to test/tune it isolated.

can this be done with linux? running multiple instances of cgminer for different devices
