Good Morning

I have set up a solar power rig to run my Gekko's. Does anyone know of a USB hub that can be directly powered with DC input, that will work with these sticks? Thanks.

Warm regards

Hi Sidehack

It's 12v coming out of the charge controller. I drop this to 5v with a DC/DC currently. Thanks.

I make a USB hub great for running these sticks, and it takes in 12VDC.

hmm I have one BM1384 running and it works great no problems yet


but how looks the command line when I put more 2pacs on my powered hub is it still one line or do I have to put another line in my *.bat file

I will soon buy more of these devices, I have good experience with the seller so that is no problem Smiley

looking forward to expanding this

Hi All,

I'm new new to this and trying to feel my way through an Rpi 3 b+ set up with two 2pacs on a powered hub to start off with.  Apologies if I have overlooked this on previous posts but is there an easy set up guide for cgminer on rpi for 2pacs?   Any links or pointers appreciated.  Please go ahead and assume that I have no knowledge whatsoever  Smiley

TIA

I am running them at 170 mhz @ approx. 76 gh/s. Yesterday i played with mhz and it was running unstable. Now i placed them back on 170 and i am getting avg 74gh/s. Any idea what might of happend. Hw-0 wu 1040( 100% for most part Wu:95-100 for each). Thank you
To add to the post i was getting .013 of dgb and now iam only getting .009-.01

Have you got a fan cooling them? Did you buy them second hand?

Have you touched the voltage pot at all? What settings was the previous owner using?

In cgminer that i am using for the 2pac what do these mean

Bm1384:02 175.00 MHZ T:175 P-174 (112:223) : 100% WU:93%

the T, P, () and then the percentages after parenthesis

thank you

Since this morning I am down to 74.2 gh/s and down to getting .005 dgb I per stick. I pulled one stick out and plugged it back in and watched it’s hash rate went anywhere from 12ghs to 30ghs in matter of seconds. I will have to pull them all off and adjust mhz on the stick individually to get them more stable. Any idea how to make the CGMiner full screen?

Thank you

T is Target, or the speed it's trying to run at
P is Plateau or the maximum effective speed cgminer's seen out of it
The percentage is what percent of target speed it's running. 100% is good.

Whatever speed you run it at, cgminer is probably going to round to the nearest 6.25MHz because that's how the internal clock multiplier in the chips works. So 175 gets 175, but 170 would get either 168.75 or 175; I forget if it rounds down or up.

As for hashrate, each stick should level out to MHz*0.11 which means 175 should see 19.25GH per stick and "170" would see about 18.6GH

74.5GH across four sticks averages out to effectively 169.3MHz per stick so if you were shooting for 170 it looks like you got it.

When you first plug in a stick, the exact hashrate is meaningless because it's estimating off the timing of the shares returned, which appear randomly. You want to give it a few minutes to settle into an average.

Well, I have been away for along time. My account got hacked about a year ago. I no longer had space to run my miners. I could never get 2Pac's to run with Minera without eventually running into rejects/errors or getting zombies after 24 hours. I also never did get them to play well with my Antminer U2's. A few years later I am unemployed with a little bit more free time(not much as a stay at home Dad). So success in getting them to run stable again(April 2017 I had them going 20 days without error.)
If I just made a place to run the two 2Pac's two years ago, I might have mined enough to get a NewPac and hub. Lol
