I'm not on a solo pool (I have more than just these units) and the pool sometimes has issues on its end. So I have it setup to cycle between the pool endpoints (with different domains / dns). But to Kano's point, I could specify multiple pools in the command and let it cycle.

Why not put you a loop in the script that cycles between pools? that way if the cgminer crashes or loses connection then it will auto resume. Then put that script in the rc.local so it runs at start up? that way as long as power is on, with cables connected, and internet access you are just about plug and forget.

I'm trying to determine how many I can run on a Pi4B. Thanks 12 no issues all over 300 GH/s Thank you for your reply. I've spent some time today trying to get like 20 of these working on a Pi4. PSA for others wanting to scale up on the Pi platform, while the CPU usage is low there appears to be a limit of around 12 devices on the USB 3 ports (including any hubs you have). So I'll have to run 2 Pi4 units to take advantage of the power savings vs. trying to run so many of these on windows (which uses tons of power / cpu and generates heat).

Quote from: Powell on November 19, 2021, 03:36:39 PM I have 2x @ 550MHz on my Pi4B (8gig version). CGminer is running between 19-22% CPU usage. Quote from: gt_addict on November 19, 2021, 06:57:48 PM I've got 6 running at 520M and CPU usage is around 15-20%. Fluctuates more than the old Newpacs but well within reason. Interesting that the CPU usage doesn't seem to be scaling up that much (unlike on windows). I'm hoping to be able to get 10+ on a single pi (with multiple powered USB hubs). So this gives me hope. Pi is stuck in shipping. Thanks for the replies!

Quote from: kano on November 13, 2021, 10:28:24 PM Quote from: acoleman on November 13, 2021, 02:38:42 AM I'm going to upgrade server 2016 -> 2019 and install the ubuntu linux sub system and see if that works. If not then I guess I'll buy a Pi4. Thanks for the replies! The WSL sub system wont work for USB mining, you'd have to work out how to give it access to USB The cross compiling windows readme is to produce a binary that runs under windows and of course wont work under WSL. You'd have to do a standard compile then work out how to give it access to USB. Alas WSL is not a proper VM and windows drags it down to a crawl. If you've noticed, it will take hours to compile the MXE system vs 10-20mins on a similar linux machine doing exactly the same cross compiling. I simply added the readme about how to use it to compile cgminer for anyone who wont run linux, but wants to compile the code themselves. Thanks. I've ordered a Pi4 Kit. In the mean time, I've spread the units out across 3 windows machines to max out the hash rates. Solid 300-400Mhz now. I never had CPU problems with the new pacs, had like 30 of them on that one Ryzen machine (also mining ETH). Thanks again for your time.

Quote from: NotFuzzyWarm on November 13, 2021, 02:39:03 AM Quote from: acoleman on November 13, 2021, 01:01:06 AM So more testing. I put 3 of these on a Win 10 Home x64 machine (Clean install, literally NOTHING on it) that has a 7 gen intel I-7 and seeing 55% CPU usage on that machine while running CGminer with 3 compac-f units ... Is this high CPU utilization (55% of 7gen i-7) normal for just 3 units? You have the Zadig USB driver loaded? I'm running 1 F at 425MHz along with 2 Newpacs on a very old Lenovo mini-PC -W7, dual-core Atom, 2GB memory and they cruise along nicely, CPU Meter reports 15% usage. Yep, used zadig 2.7. Win USB v6.1.7600.16385

Quote from: sidehack on November 13, 2021, 12:47:40 AM I factory-test these on an old Dell 755: to give a hint at the age, service tag says support ended 11 years ago. 14 sticks per machine, 400MHz. Don't know if you have multiple USB busses on that machine, but if you do, split the load up. I run seven per bus. Thanks for the reply! Were you testing on windows or linux?

So more testing. I put 3 of these on a Win 10 Home x64 machine (Clean install, literally NOTHING on it) that has a 7 gen intel I-7 and seeing 55% CPU usage on that machine while running CGminer with 3 compac-f units set to the settings mentioned above (--gekko-compac-freq 400 --gekko-mine2 --gekko-tune2 60 --gekko-start-freq 300 --gekko-tune-up 85). Only getting 190 - 200 mhz out of them with a 12 inch fan on high blowing at them from 2-3 inches away. No other USB devices in use. This hub was previously used to power 4-5 newpacs at 250mhz no problem. Is this high CPU utilization (55% of 7gen i-7) normal for just 3 units?

Using the @kano version of cgminer with about 18 of the compac-f units I'm seeing 100% CPU usage on windows server 2016 on AMD Ryzen 2700 CPU. Can't even get full speed out of them (struggling at 200). I never had a problem like this with the new pac units. Anyone else seeing this high CPU usage? Any work arounds? Would 18 of these (properly powered) run on a pi based rig or would that not have enough CPU? Thanks
