GridSeed 5-chip USB miner voltage mod

[Cablez]

I would love if someone makes a new CPUminer. I would even pay a bounty for it!

Like this one? 

https://github.com/siklon/usb-miner/tree/master/software/cpuminer

Short summary:
* Added hashrate statistics
* Added auto per-chip frequency tuning
* Added JSON API at port 4028 -> send {"get":"stats"} to get stats for each miner/chip
* Input any frequency you want

Code:

 -G, --gc3355=DEV0,DEV1,...,DEVn      enable GC3355 chip mining mode (default: no)
  -F, --freq=FREQUENCY  set GC3355 core frequency in NONE dual mode (default: 600)
  -f, --gc3355-freq=DEV0:F0,DEV1:F1,...,DEVn:Fn      individual frequency setting
  -A, --gc3355-autotune  auto overclocking each GC3355 chip (default: no)

It should work on Rpi, but I haven't tested it yet.

yes but to use on Windows as I'm not an Rpi or linux urser. And I know alot of other people interested in this for Win as well.

with above version you have to install all kind of directories into win to make it work, even less user friendly than bfg or cgm

I would be very thankful if anyone could find out why some pools don't work with my cpuminer fork, I have been debugging a long time to no avail...

[jamieb81]

I too would love to see cpuminer get an upgrade!

By the way, what is Commercial Text?

I used wolfey's mods and they work great!

BOUNTY FOR CPUminer on win!

That is great!  Wish I new enough to help with debugging.

sandor - just to confirm, is this for single mode operation only or both single and dual?

I'm having trouble with 2 units not submitting shares after doing the 47K mod.  One of the units was submitting shares until I did a power cycle.  I managed to get it to submit some more shares after pushing the reset button on the PCB but the unit just stopped again.  I have checked and I'm getting 1.63V across the resistor, and continuity to the regulator.  Im using scripta on a pi to control the units.

I have another 10 modded units running fine.

Has anyone else had the same problem and found a fix?

[happydaze]

What frequency setting are you using for the the two that won't submit shares?  Is it the same frequency as the others or lower?  Individual Gridseed vary in the amount they can be overclocked.

Try different usb cable, try different usb port, try different power barrel connector , reset miner  let us know how that goes

[cmilian]

Here is Mine, Is this good? Just the one resistor replaced with a 49. at 1200 Mhz.  Am I pushing too hard> will I damage my Gridseeds?


 2            |  1.04/ 1.02/ 0.54Mh/s | A:115 R:5+0(none) HW:0/none
--------------------------------------------------------------------
 GSD 0:       | 510.6/502.5/261.7kh/s | A: 56 R:3+0(none) HW:0/none
 GSD 1:       | 510.6/500.3/283.9kh/s | A: 61 R:2+0(none) HW:0/none

I noticed that My Miners are accepting more when they are just starting. Could this be a signal telling us that I need to lower frequency? Or is this a Mining Pool issue?

DOnt look at the pool, if you have been mining for awhile you will know dont even bother, pools are never accurate.

I only ever trust the miner, Cgminer is great for checking accepted, Rejected, WU shares, Hashrate.

Pool stats are exactly what you want to pay attention to. The stats you see are what are being used to determine how much money you make!
It's local stats that don't matter, there.
Local stats tell you what your miner's performance is and they too are inaccurate in that it's determined by the way the program is written and how it calculates hash rates in the first place.
I find cpuminer is the most stable and trouble free of them all even though it doesn't' show local hash rates. So what! That's not the stat that tells you what you're gonna get paid pool side anyway.

I am not talking in regards of getting paid here,Your going to get paid either way at the end of the day! Im talking about tweaking your miner and ACTUAL miner performance.. mann I am looking at the pool and sometimes it shows 2000KH more than my actual miners is showing you think I am going to believe that shit ?? LOL so no I wouldnt pay attention at the pool in regards of tuning your miners, Pool hasrate is all over the place and absolutely ridiculous to check your actual miner performance against.

I am not used to this, coming from GPU land lol Not once have I heard people checking the miner performance in a pool Yes obviously the pool is where you get paid but that does not mean that is what your miner is performing at.

OK guys, I was using BFGminer to have both seeds in one instance. But this was not working It was showing 1000 KH/s on bfgminer, but mining pools where showing an average of 400 KH/s.

I got sick of it and change to CPU Miner, running one instance per each gridseed. Now I am hashing on the Mining Pool side at 850 to 1010 KH/s

I EVEN FOUND 2 BLOCKS! am i supposed to get credit for finding blocks?
I am happy

That is for single mining only.
Issue with reject on some pools has been fixed BTW.

Is there anyone with a Gridseed blade that wants to help me add support for it?

OK guys, I was using BFGminer to have both seeds in one instance. But this was not working It was showing 1000 KH/s on bfgminer, but mining pools where showing an average of 400 KH/s.

I got sick of it and change to CPU Miner, running one instance per each gridseed. Now I am hashing on the Mining Pool side at 850 to 1010 KH/s

I EVEN FOUND 2 BLOCKS! am i supposed to get credit for finding blocks?
I am happy

Yup, you had the exact same problem as me with BFGminer. showing 1000 on bfg but only 300/400 on pool.

went on CPUminer and got 850 to 1100 and found alot of shares, blocks.

Now if CPU miner was fixed to show KH/s it will be perfect

Take a look at my cpuminer fork, it has hashrate display along with many unique features.

I've been using CPU miner on my gBlade.  Last time I checked my hashrate was about 2900 x 2 server side. This is with freq at 850mhz.

Would like to test your fork, but I'm on windows.

[jamieb81]

I encourage everyone that wants this CPUminer fork for windows ( like me ) to write to http://cryptomining-blog.com

they have been compiling ones before and worked great. Hopefully if enough ask them they will do it with this one

What frequency setting are you using for the the two that won't submit shares?  Is it the same frequency as the others or lower?  Individual Gridseed vary in the amount they can be overclocked.

I have tried multiple frequency from 700 to 1175.  I have also loaded a fresh image of scripta.

I'm having trouble with 2 units not submitting shares after doing the 47K mod.  One of the units was submitting shares until I did a power cycle.  I managed to get it to submit some more shares after pushing the reset button on the PCB but the unit just stopped again.  I have checked and I'm getting 1.63V across the resistor, and continuity to the regulator.  Im using scripta on a pi to control the units.

I have another 10 modded units running fine.

Has anyone else had the same problem and found a fix?

Try different usb cable, try different usb port, try different power barrel connector , reset miner  let us know how that goes

I have tried all these and nothing.  Is there a correct procedure for resting the units?  I simply pressed the reset button while i had 12V power connected.

I let the units run overnight and still 0 shares submitted.  I will try disconnecting the units for a couple of hours.

Look up please.

[powersup]

can anyone actually confirm the value of the resistor removed for the mod?  Ive been looking at the schematic  and according to the schematic its a 127k resistor, but the bill of Materials has it as 33k?  also it isnt R52, in fact it R139 for anyone who is interested.
