GekkoScience NewPac / Terminus R606 (BM1387) Official Support Thread

[os2sam]

Am I to believe that it is impossible to change the frequency with the argument " --gekko-newpac-freq xxx" once compiled?

I can change frequencies.

[MoparMiningLLC]

Any thoughts on which of them to look for the frequency parameter or whit it might be called so I can search for it?

I think it ends in .conf

I've looked through the CGminer folder and found no files ending with .conf, additionally I've searched through the configuration files mentioned above.

I've also read the READ ME file but I cannot see where the Gekko Variables (arguments) are stored.

Please do not tell me that I will need to recompile the CGminer.

let's start with the first question needing an answer - what os? Windows? Linux?

[Golddustpeak]

Well that tool a while but I'm now at 150MHz................

I finally found and changed the cgminer.conf file.
It was hiding at : /root/.cgminer/cgminer.conf

I think it ends in .conf

THANKS !

Glad to hear it.  I've never saved a configuration the .conf file before so I know very little about.  I like doing things from a command line.  However on my Pi 4 I did create a .sh file which contains my command line, which is quite lengthy since I have 4 or 5 fail over's.

Make sure you have good cooling on your sticks as you ramp up your frequency.

Yup got a pair of ARCTIC Breeze blowing on them 

[slurfius]

Did you run it direct from your morherboard usb port?

yes

I watched the hashrate fall on the pool and checked later and saw that the cpu on the same machine slowed down mining monero around the same time and then the computer crashed and bios said that I needed to make changes. I think the newpac overheated pulling a ton of power and the extremely overclocked cpu didn't get enough power causing the crash that might have saved my newpac.

Be careful with cooling them I'm here because I ran my brand new stick at 125 and I'm afraid I may have cooked it. It ran great for hours then the hash rate went down gradually overnight and now it's hashing at 4.669 GH/s according to slush pool. I thought I wouldn't need a fan because my gaming tower has big top and rear intake fans and it seems like the air was moving a lot back there by the usb port but I think I was wrong.

Update: the newpac seems fine it ran at 100mhz all day and after an hour or so it resumed average hash rates between 16 and 33.

[Golddustpeak]

New question......
I'm currently running 4 Gekkoscience-newpac @150 MHz on a gekkoscience hub being cooled by two ARCTIC Breeze blowing on them.
The heat-sink temps range from 79 deg. F. to 87 deg. F. and the board temps range from 81 deg. F. to 85 deg. F. after 8 hours of solid running.

The ambient room temperature is between 75 deg. F. and 76 deg. F.

My question is how much higher can I SAFELY raise the frequency and maintain a safe stable environment?

TNX

[slurfius]

I'm going to get a fan and start at 200 then go up 25 a day until I max the system out. Seems like that is what most have done

[gt_addict]

I had a single 92mm fan blowing directly down onto 6 newpacs on a GekkoHub and ran comfortably at 650m for months. Ambient room temp was 20-23c (not sure what that is in F). So if the cooling is good then you should be able to reach that ok most likely.

[Golddustpeak]

Update...............

I bumped the frequency up to 200 MHz and now I'm measuring:
83 deg. F. to 89 deg. F. on the boards
79 deg. F. to 85 deg. F. on the heat sink

This is after at least 8 hours of continuous running.

[Golddustpeak]

And another question (or two)...................

As I look at the various mining pools I see a minimum withdrawal of .001 BTC.

Has anyone found a pool that accepts less than .001 BTC that they like?

Are you doing solo in hopes of success or just waiting for the payout?

What pools do you like and why?

Sorry for all the questions....................

kano.is will payout less than that, but your hash rate needs to be above the dust level which is probably around 500Ghs or so.

Asking about pools tends to get a bit ugly sometimes as we all have differing opinions on what constitutes a good pool to us.

So it seems my plucky little R606 is unwell. It stopped around 11:30am (now 6pm) with the error:-

"Gekkoscience detect (1:4) failed to initialise (incorrect device?), resetting"

I have shutdown the Pi4, turned off the R606 power supply (HP server 460w with Gekko Breakout Board) and restarted it twice so far. Turned down the freq to 700m and it starts hashing for a while and getting over 500m quickly. But within 30mins or so the error returns.

Currently while writing this I have switched USB leads and ports on the Pi4 to see if that is the problem.

No lights are flashing to indicate a fault (orange power led on constantly, and white led flashing for shares).

Its been at 800m for months without any issues. There have been no power outages or anything to disturb it today.

Update:-
So it seems it may well have been the port or usb cable that was at fault. It has been running 700m for the past 4 hours with no issues. Just increased it back to 800m. I'll leave it running overnight and see what I wake upto.

Update 2:-
Running at 800m V5 as it was before. Amazing how a cable and/or port can cause issues out the blue.

Hi,

I've recently added a second Newpac to my Sipolar hub.  The original unit would run steady at about 50GH at a frequency of 225.  When I add a second unit to the hub, both units fall to an ASIC plateau of 180, even though the second unit when run alone also runs solid at 225.

Is this potentially an issue with the hub?

Can I overcome this issue by tweaking voltage up on one or both units?

TIA

Maybe the hub isn't supplying enough power for two.

[gt_addict]

Probably an issue with the hub. What hub is it? Mains powered? What port did you plug the second stick into? Right next to the other stick? Could be the ports share power delivery components. Try plugging them in at opposite ends.

I’m going to run the gekkoscience  8 port hub and power brick with 6 newpacs. Should this system be able to run the newpacs at 650 with proper cooling?

Not sure the brick will be enough juice for that. Also im not sure the barrel jack itself is rated for the amperage
