Topic: GekkoScience has a new stickminer that does 300+GH - page 49. (Read 22553 times)

If anyone here has an Pi4B with these setup, would you please reply with how many units you have running, at what Mhz, and what your CPU usage is?

I'm trying to determine how many I can run on a Pi4B.

Thanks

Wow.  This is awesome!  The amount of work that you put into this is admirable.  With some sexy lighting that would be an amazing functional display piece.  How are the noise levels with that radiator fan?  Is it basically quiet?  What amounts are you generating with that?

I must say, you don't see people doing cool things like this with waterblocks very often.  Maybe you could get working on a submersible version next to really push those things to the limit.    Thanks for sharing this.  Great work.

Glad to see you got it running at a solid speed! No idea if there's a way to run multiple diff frequencies under one instance of cgminer but i don't think so.

Regarding the sticks running better at different speeds, with the Newpacs & these I've found that you def gotta play around with the frequencies a bit to maximize each stick. No idea if this is accurate by my guess is that the silicon in the actual chip responds differently to each frequency. That or some sort of combination of power draw per USB port, cooling, frequency and the environment all likely play a factor.

I have had some that run measurably faster at lower speeds like 350-450 MHz than the same stick on 500+ MHz.

Thanks for that.

Does anyone know of a way to run them all together but at different speeds under one cgminer?

Now here's whats odd... After seperating the 4 sticks (2 on each hub) The one stick that has been giving me trouble runnning stable at 400mhz runs perfectly fine at 500mhz...  

I have been battling with this one for quite sometime just trying in the upper 300's and lower 400's but apparently needed to push this a bit harder to keep the juices flowing...  Who woulda thunk???



Here is what it looks like running overnight:

I believe you can only run one frequency per instance of cgminer. so if you want to run different sticks at different frequencies, you can open a new tab in terminal and just enter the new command.

should look something like this:

sudo cgminer -o stratum+tcp://stratum.kano.is:3333 -u zzz.worker -p x --suggest-diff 442 --gekko-serial "GS-10050486" --gekko-compacf-freq 350

if you wanted to run more than one stick at the same frequency, just add commas.

sudo cgminer -o stratum+tcp://stratum.kano.is:3333 -u zzz.worker -p x --suggest-diff 442 --gekko-serial "GS-10050486,GS-10050489,GS-10050487" --gekko-compacf-freq 350

you should also look into adding these at the end if you're having trouble with under hashing

--gekko-compacf-detect --gekko-start-freq 300 --gekko-mine2 --gekko-tune2 60

so at the end the command might look like:

sudo cgminer -o stratum+tcp://stratum.kano.is:3333 -u zzz.worker -p x --suggest-diff 442 --gekko-serial "GS-10050486,GS-10050489,GS-10050487" --gekko-compacf-detect --gekko-compacf-freq 350 --gekko-start-freq 300 --gekko-mine2 --gekko-tune2 60



dude, this is sick! great work. i was thinking about trying liquid or immersion cooling eventually but it seems like i can get 300 GH+ range w/ just some fans and the right PSU [and obviously sidehacks hub]

I'm sorry for the sillyness here but I'm still going crazy with a single stick out of the 15 that I have ordered that won't hold up at 400mhz.

It's not the hub so I can rule that out. Even running it by itself it just one falls flat on its face.

What is the command to underclock a single stick on a version of cgminer if I am running more than 1 stick?

I've tried these with no luck to control a single stick out of 4:
--gekko-serial "GS-10050486" -freq 350
--gekko-serial GS-10050486 -freq 350
--gekko-serial-freq 350  "GS-10050486"
--gekko-serial-freq-"GS-10050486" 350

Any ideas?

Just wanted to share a project I have been working on.  The stand is designed and printed by me.  For air flow I have the radiator fan blowing down onto the miners and a fan on the back blowing across the miners.  Everything is powered by a 700w server power supply from Parallel Miners.  I am using the Alphacool MCX ram water blocks to cool the ASIC chips.  The water block clamp was designed and printed by me.  I am using a Raspberry Pi4 with 8gig Ram running 64bit Ubuntu Mate.  I have ordered another one of sidehack's USB hubs and plan to add either my 6 2Pacs or some more Newpac's if I can get them.  I am able to run the fans at a low RPM so the rig is very quite.

The hottest temp I can find on the back of 3 CompacF's is between 35c & 39c.
The hottest temp I can find on the back of the 6 Newpac's is between 39c & 43c.
None of the miner boards are hot to the touch.








I sure hope sidehack does another batch of the CompacF's.  I would love to get some more of them. 

Thank you sidehack for the work that you do.

Well a compacF is around 5 or more times the speed of the older NewPacs.

So one compacF needs the same work generated and written to USB as about 5 NewPacs

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.

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.

Yep, used zadig 2.7.  Win USB v6.1.7600.16385

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.

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!

Linux, always linux. My testers run Debian, which Raspbian and Ubuntu are also built from. I run a beaten-into-submission Win7 on some machines; anything newer isn't really allowed inside the building.

Windoze Sux.  Use Linux.  Had similar issues with my R606's on Win7.  Switched to Ubuntu and issues went away.  Then switched to the Pi 4 and all was good.  Don't know how 18 sticks would fare vs. my two 606's.

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?

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.

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

Yep they are part of 'all'
I've only used the new function in the compacF
