I remember someone hooking up a direct 5v supply to a stick (compac/2pac) and managing to get some really impressive numbers with decent cooling. Its probably somewhere in the forum but a search didn't reveal anything within the first few pages of results.

USB devices work on 5V, even if the usb hub sometimes have 12V power supply. Running the Pi on the same hub as your miners can create a negative feedback look and most of the new Pi versions are really power hungry (2+ amps).
Ok, That's what I had figured but just wanted to check. Also placed the Pi back on its own supply. I did test the 10th port, it transfers data but I noticed it has a charge mode light and a data light. I have to assume I don't receive the extra amps with a data device hookup up. When i plug my phone in it switches to fast charging mode without data.
gt_addict those are some awesome numbers. Its amazing to see how little the diminishing returns are in terms of Mhz and gh/s.
It makes me curious as to how far the chip and unit could be pushed with adequate power and cooling.

Yeah that's my biggest concern and the main reason I haven't tested anything above 500 yet. I'm definitely picking up a gekko hub asap the layout, the fan header, the juice. I need one haha. What kind of GH/s do you achieve at 625mhz?
I get around 140-142ghs per stick at 625m.

the 10th port on anker hub is charge only, I would grab a Gekkoscience USB hub from Amazon instead:

You want to be careful you don’t pop your usb hub when OCing. I’m running mine 6x newpacs at 625m on the gekko hub and wouldn't go any higher as I could well cause some damage (and thats after sidehack tried to make it as bulletproof as possible). No idea how that anker 60w is laid out. Just something to keep in mind

This anker's specs are meh:

■ Each data port provides up to 0.9A current.
■ The 10th port delivers a full speed charge of up to 1.5A to BC 1.2 specification-compliant devices. Refer to the table below for popular compatible models.
A BC (Battery Charging) 1.2 port delivers fast charge (up to 1.5A) to your USB-enabled device. Charge speeds are even faster (up to 2.0A) when the hub is disconnected from a computer.

Not sure if the 10th port also transfers data, but if it does its the only port on the whole that delivers above .9A. Ill test it later, from reading I believe i'm not actually supposed to be powering the Pi from the charge port, that's a bummer. (Hub must be powered by both a power adapter and an active PC/laptop USB port.) Makes it sound like it gets extra juice from the usb port as well.
Do these units operate on 5.5 or 12v?

Yeah I wouldn't recommend Windows 10 to anyone who doesn't like paying too much for crappy bloated software that also spies on you.

So I have been running 5 Sticks 400 Mhz @87 Gh/s. All on a Raspberry Pi 4 4gb.... Zero Issues.
I have to believe that it was Windows 10 causing Zombie effect. Has yet to happen on Pi.
And I can remote in.

Got everything up and running, Pushing 500mhz strong. Has anyone pushed their newpacs past 650mhz?
https://www.youtube.com/watch?v=0fYfkv6byK4 Heres a vid of the setup. Ready to solve all the blocks!

I'll give it a go, TY.
**UPDATE**
Raspi 4 All setup, took some tweaking but got it running with All 5 Newpac's.
Currently running 200Mhz @45Ghs/s per stick.

I just ran raspian and install cgminer like the post on the first page says. It was a very simple process. I however have the gekkohub also. I wouldn't plug the miner directly into the raspberry pi.
May 31, 2020, 05:08:02 PM
I have quite a few raspi's, just noticed I have a 4 w/4gb RAM. Setting up now for CGminer. any Tips for loading software? Are you running an injected version or running Noobs w/installed CGminer?
May 31, 2020, 04:59:36 PM
Model 4 with 4gb ram, honestly seems overkill. It consumes hardly any ram.
May 31, 2020, 04:28:06 PM
Which version? How much Ram.
May 31, 2020, 04:14:40 PM
Has Newpac been tested on raspi 4 yet @sidehack ?
I currently have 5 of them running on one.

Anything that is running anything other than Windows 10, you're going to get better results. These devices make a fairly intensive use of USB traffic, and both timing and packet size are particular. Win10 for some reason hoses up or in other ways abandons the standard ways of doing things so traffic patterns are a lot less deterministic and that makes things choke.

This is where I was taking readings
- After Adjusting All to match
- All tested average @43 degrees Celsius @center screw on back of MB
- Stick (1 - 5) .4450 while running for 10 minutes @ 300mhz
- This is the best I can do, let's see How long I can keep running without Zombie reset. I tried using gaming Laptop to run but unable to get it to stabilize (script kept adjusting frequency of each stick. May switch to Raspi.

The chips have to self-balance so the reading across any one chip will vary. The factory setting is 830mV across the pair.

So I have been running experiments with each Newpac(BM1387) stick and its gekkoscience 7 port hub(fan is in port 1). When all 5 sticks are inserted they are in sequence starting at port 2.
I have test each sticks voltage settings all using port 2, on switching from 1 stick to next at times I get close to same voltage reading, but other times when inserting cold I am getting fluctuated readings.
- 1st round I was averaging around .4600v , 2 sticks did read @ .3860v & .4020v.
- cold on some voltage starts low around .2880v & stabilized @ .4000+v
- I am trying to adjust all to around .4500v across all
Questions:
1) Are these reading normal? (Voltage differences when cold vs hot)
2) What is Normal Running voltage of chips? (Don't want to set too high and damage chips)
3) Should Voltages differ from port to port on hub?
Test Equipment:
- Brymen BM867s @500,000 resolution on 5v reference device is 5.00301v.
