Topic: GekkoScience NewPac / Terminus R606 (BM1387) Official Support Thread - page 59. (Read 61906 times)

I have a Pi4 with 4gb, run 2 r606 at 800mhz over 2Tb.

I updated kernel 64bit as was suggested.  Pi4 works faster.

You may still run into issues regardless of splitting them out.  Laptop hardware typically doesn't have the amount of bus traffic lanes as a desktop PC.  Some are usually limited to only 1 or 2 usb ports and are often using at least 2 bus lanes.  What model laptop are you currently using as a controller for these miners as you have quite a bit running off it     You may end up having to split them out on multiple devices.

I ran into clashing issues when using the Raspberry Pi 3 b+.  As it had only 1 bus lane that routed all 4 usb ports and internet traffic through creating a bottleneck.  You may be running into a similar issue with that laptop having a grand total of 24 miners (various makes) on that one machine.

You may have better luck migrating them over to a dedicated desktop or a couple of raspberry pi 4's.

I only have two R606's.  So if I want to run them in two separate sessions I should be able to use --usb GSI:1 for each session and have it only pick up one device per each instance.  Using the identifier for the other devices you should be able to tell CGMiner what types you want in each instance.

Also the top post has information on how to identify the Bus numbers and use that method.  Also Mstroziers post has info at the bottom of his instructions too.

You can also search through the CGMiner thread on different ways to split devices up.

Edit: oh Sidehack also gives each device a serial number and VH added an option to specify what S/N you want in each instance, do some searching in this thread, I think, for those command line options.

Hi 0s2sam. I would like know how I identify each usb device i.e. 1:7, 1:8 so that I can then isolate them from different instances as they currently clash.  I have x2 R606 and x4 Newpacs on 4.11.1, x12 Rockminers on a modified 4.10.0 and x6 2Pacs on standard cgminer 4.10.0.  x3 GS hubs, HP1200, Lindy USB cables direct to Win7 laptop.

The only way to stop any clashes when running together is to use --usb :1 in the instance for the R606.  I thought there was a command 'cgminer -n' that will identify which sticks are in which ports to mask their identity from other devices?  I'm getting there and learnt a lot in a short time.  I just need help with command lines/instances to get all running together...I will run around the block naked if this happens!  The RM's use 2Pac commands and act in the same in every way.  I will ditch them in time for more 2Pacs and Newpacs but I didnt know enough at the start.

Thanks for any help.

cgminer -n just enumerates your connected USB mining devices.

If you want multiple instances just start additional ones.

Are you asking how to separate devices in the separate sessions?  If so what devices do you have?

I’m using Win7 so would the ‘cgminer -n’ command be used in the command line such as the following:


This has been my main issue and knowing how to create separate instances isolating devices.

Update for Raspberry Pi 4 owners.  They have finally released an update for our kernels to 64 bit.  Running the update will help speed up your system to some degree and open the door to other linux based 64bit apps that wouldn't work before.  Sadly existing apps on our systems are still currently 32 bit however this gives room for future growth.  And also as a mining controller, if there are any future mining software that requires 64 bit processing you'll have your device in proper order.

To see what your current kernel is at just type the following command:


And you should get the following results (or close depending on which update you are running on)


Yup, named my machine Goober    But from here you will see the kernel is armv7l  now the update process:


and you will be presented with the following.  Take a Y for the update


Once this completes it will tell you to reboot in order for the firmware to take place.  Do not reboot yet.  There is one other change we will need to make first.  Type the following:


Then scroll all the way to the very bottom and key the following


Then hit your control key and X.  It will ask to save. Take a Y.  Then it will request filename.  Leave it defaulted as it'll show config.txt just hit Enter and now you are done.  Reboot the Raspberry Pi.

After reboot, to verify you are now at 64 bit just key the uname -a command again as follows:


Now you'll see aarch64 is listed now.

**edit**

Also don't forget to do the standard updates:

Update: after getting cgminer running for a full 24h on my Pi @ 400MHz for my NewPacs, one is doing 88.4GH/s (normal), the other two are 80 and 77.

Whatever you're looking at and calling it a chip, if it isn't a flat black square only visible by removing the heatsink, it's probably not what would normally be considered a chip.

If we did a different "generation", it would be a different product with a different Compac-derived name.

I highly recommend some form of Linux for running these. That's what the driver is native-built for and what all the hardware is tested on at the factory.

Yeah, I tweaked the voltages on the 2Pacs, but not the new. I guess I assumed there were different generations of NewPacs, since the chips are different colors. Evidently I was wrong. I'll swap over to a Pi4 then and see what results that yields.


Ah, that makes sense. I've seen the plateaus, yeah. And I've got them quite cool, don't have a temp laser but they're only slightly warm to the touch, average coffee is warmer.


I've got 2 fans on them, I'm confident it isn't a heat issue - one fan is top down, the other is angled in from the side. I love loading the OS off a flash drive, I'll give that a shot before I buy a pi

Thanks everyone.

I need to look into getting a pi to manage my r606 but to be honest I am completely ignorant when it comes to them - having never laid hands on one or even seen one in person lol

Sidehack nailed it.   If you are using a Windows Machine I would highly suggest switching it over to a Linux based machine or SBC (Raspberry Pi 4 as example of SBC).    I have 3 Raspberry Pi's in total lol, 2 are 4's and the 3rd one is a 3 b+.  I use the 3 b+ as a pihole server.  The 2nd Pi runs my mining hardware.  And the 3rd one I use as my everyday machine.   2 watts of power draw on normal operations (web surfing, email, videos etc) and 5 watts whenever it hits full load.  No complaints.   I use my windows machine mainly later at night if I am in a gaming mood.  As yup that one is a windows 10 machine with a Ryzen 2600, 32gb Trident rbg memory, multiple ssd/m.2 /hdd drives for storage and a MSI RTX 2080 gpu for 1440p gaming entertainment.   I have gotten where I use this machine less and less.

Anyway, onto the miners:

On my Raspberry Pi 4 I have 4x Newpacs and 2x Futurebit Moonlanders 2.   All 4 newpacs are clocked at 450Mhz.  The average on them are as follows:

1: 100.7 Gh/s
2: 102.0 Gh/s
3: 102.1 Gh/s
4: 102.2 Gh/s

However their 5 second hash rates range anywhere from 90.5Gh/s to 105 Gh/s.  I have the Gekko hub powered by a HP Server PSU since I'm also running 2x R606's off it.  The moonlanders I have those clocked at 700 Mhs and getting 3.98 Mh/s each.  So the power draw being used up on this gekko hub would be the same as 6 newpacs.   I have 2 Artic Breeze fans (one is the bendable usb fan and the other is usb driven as well but stationary as it has a base) on the newpacs and moonlanders.  Both USB fans are plugged into a 4 port additional USB hub that is in turn taking up the 7th port on the gekko hub    No power issues at all.  And plenty of air flow on my miners.  The room average temp in the day is typically 78 Degrees F.   And 68 - 72 Degrees F at night.  I live in mountain areas and often have a window up and desk top fans (and ceiling fans) running all day.  Don't need AC much with current temps.

If you just want to test and see.  Take at least a 16gb USB stick and load Linux on it and boot off the usb drive.  I did this for a while with Ubuntu on a GPU mining rig.  No hard drives or SSD.  Just a 32gb usb 3.1 stick as a drive     You can try that and see if you notice a difference.  And by then, you may like Linux well enough to remain on it.  I had to use 2 usb sticks to get this to work though.  I put the bootable flash on a 8gb usb stick.  And once I booted my machine up with that, I had it format and install the Linux OS over to my 32gb usb stick.  Then next time I rebooted, I had only the 32gb stick in and ran my os off that.

** Edit **
Also, if you are using only 1 fan on that hub then you possibly are not getting enough airflow on them and could also be a factor at hitting roughly 90% of your mark.  I have two of them blowing on my mining sticks from different angles to make sure all of them have proper amount of air.   I'd suggest getting another fan to add to that mix and possible one that is corded so that you can move it around for a better angle.

I would assume you are referring to our serial # tags we used to place on the units. A number of customers have asked that we no longer do that, hence, the newer units dont have product tags on the side of the heat sink.


Like sidehack did already answer, not all chips are going to hit the same speeds. have you seen any plateau's from cgminer and had it step down the frequency on the units? and Always remember, more power, more heat, so more cool means better hash rates.

First off,


Even as the manufacturer, I have no idea what this means.

Second, Windows 10 sucks. Don't use it. I mean not just for mining, but like for anything. Ever. In addition to just being terrible in general, it also does some weird stuff to USB packets that has caused issues with R606 hashrate and stability. Might be bumping into some of the same issues.

Third, have you adjusted voltages at all? I'm assuming you have at least on the 2Pacs in order to get the hashrate you have, since that's way above stock speed. NewPacs with top-shelf chips can run 600MHz at stock voltage but I only guarantee stock speed on every stick; getting more than that will require tuning. It's also entirely possible one stick is inferior. The chips we get are kind of a grab-bag for quality.

Ok, so I've finally got all the correct pieces together, and I'm scratching my head a little bit. I've got the GekkoScience 7-port hub, the GekkoScience 12v 8a power supply, 3x NewPacs (one older generation, 2 newer generation - the older one has a sticker on it like the 2Pacs did with it's serial on it, the 2 newer ones don't and the chips are tan colored instead of black like my original NewPac), 2x 2Pacs and an Arctic Breeze USB fan. There's a secondary Arctic Breeze fan being powered by the pc tower to keep temps down.

From what I've read, the hub should be able to support like 6x NewPacs at 600MHz. I'm running my 2Pacs at 275, and the NewPacs at 450. None hit the hashrates they should; at 450, the NewPacs should be hitting 102.6, and the 2Pacs at 275 should be hitting ~30. Two of the NewPacs are close, they're at 98.23GH and 99.95GH, which is within 5% of where they should be, but the 3rd is sitting at 91.9GH and the 2Pacs are sitting at 24.71. They've been stable at least, and I'm pulling this data after about 24 hours of hashing. Is there something I'm missing?

I'm running the newest CGMiner version from the front page from Windows 10. I've seen one of the sticks hit 101GH at 450 but that's the best I've seen. Does this come down to operating system? I've also tested without the 2Pacs on the hub and I get similar results. Could it be that one stick is just inferior to the other two?

we have a handful available for immediate shipping but large scale orders are still in production.

Is there an ETA on the next batch of 606’s?

I cant wait either - even though I have to return my R606 - I was happy with how it performed when it was working so I can imagine that anything new coming will be just as good or better.

can't wait to see what Asic is coming.

Since there have been at least one  other dud you may as well return it and wait for a replacement.

I had not realized one other was returned. It is likely enough yours is the second dud.
