Is there a reason that I should just start at the highest power and frequency and then just back up from there?  I'm using a Bitmain power supply from my old L3 so that should have plenty of power.

I guess what I'm saying is I want my target to be as high as possible.  Is there a harm to setting the frequency and power to it's highest setting and then backing down?  I don't want to burn anything out.  What is the highest frequency?  If I increase the power all the way and just let it autotune, will that do it?  Sorry to be so dense.

Hey guys,
Finally got my hands on 2 R606's and i am having issues with one. First one plugged in downloaded driver works perfect.(Trying to run them together same computer) Second one i plug in turns on fans liughts are on but it will not show up in the miner, the program runs shows deficulty etc but the miner is not showing up. only code i get it says failed to intiliaze and open device failirue err -12.
Today i finally got the second one  to run by it self but i want to run them together on one computer and am getting the codes above.
any help is welcome

If you are running on Windoze plug in both units and run zadig and make sure both are using the WinUSB driver.

I received my first R606 and it was DOA.  The device could be seen, but no chips could be found.  I called the vendor and they sent another one which is working great.  They didn't want the old one back, but I just can't get my head wrapped around just tossing it.  Is there someplace I can send it for repairs?

it is the rpi 4 - i run it headless and i am running the raspbian that came with it.

Also don't use a USB Hub, go straight into the PC.  Mine wouldn't go over 200Mhz when I used a Hub.

Hello All,

Relatively new to the mining scene and trying to learn with some USB sticks how to configure CG miner.  Ran into an issue.   I have CG miner version 4.10 that was running two BFL Jalpenos and a Block disruptor.  I recently acquired a NewPac BM1387.  All four devices are plugged into an Anker USB 3.0 external hub with a usb fan for active cooling.

CG Miner 4.10 didn't detect the Gekko miner but the link to their version did but didn't detect the other miners.  So Currently I have two instances of CG miner open (Version 4.10 for older miners and 4.11.1 for the Gekko Science one.

If the CG miners are ran solo the devices run fine however, if I try to run with both instances open I get an the following error "USB init open device failed, err -3 you don't have privilege to access - BSC device " on the CG miner 4.11.1.  Even while getting this error on the CG 4.11.1 miner the other miner (4.10.0) continues to run fine with no errors.

Any thoughts on that causes this behavior?    I tried to limit the number of USB devices on the first miner to see if that fixed it unfortunately it didn't.  Below is the config I am currently using for the CG 4.10 miner.

I am using Windows 10.  read through the read me and found something about limiting through driver.  However, when I save my config and try to run I can't tell it is limiting anything    Below is my current config file.  Even when I set all the values to 0 it still mines like the line isn't there lol.  Is my syntax correct for that line?
