amix, are you using a permanent tip?
if yes you can kill it with scraping
try a tip “clean&tin“ or “reactivator“
Topic: GridSeed 5-chip USB miner voltage mod - page 25. (Read 157001 times)
Hello
I would like to share with you some impressions about Sandor_Cpuminer vs Bfgminer.
This is my setup graph, it's a bunch of Gridseed running from a raspberry:
Pods are still un-modded so original ones by various sellers (but they look like the same inside), as mod they only have the fan attached to 5v external supply. (via usb)
I tried first bfgminer with a frequency of @850 (the best to not get HW in every pods) you can see the red circle, it was not a great hashrate I was expected slightly more and they also had a drop down during the night.
I was very unsatisfied so I gave a try to cpuminer (I never tried it) and I discovered the Sandor's fork with the auto-tune feature and BOOM!
Hashrate went up immediately and thanks to the auto-tune feature it can go slightly more upper the extreme-limit for a limited period, but in general hashrate now is more than I was expected to obtain and it seems to be definitely stable (no drops down).
Also please notice the stale columns, with bfgminer they were a lot while with cpuminer they are almost 0.
So, many compliments to Sandor, he did a really good job.
Now I think the (small) problem is that cpuminer hasn't neither a summary (but I saw Sandor is working on it) neither an RPC to get stats/devs info, and so it's not possible to fork a scripta like web interface to work with cpuminer (sad while it's not indispensable).
I think a bfgminer with the sandor-cpuminer features (like auto-tune and per device/proc overclock) could be the best option possible, but I don't know the work needed to integrate the sandor's work on bfgminer (neither if it's possible).
Anyway thanks for excellent job.

Have you tested Cgminer? If people like the autotune so much maybe get someone to implement it there as it is MUCH easier to use and visually better also.. Better failover system... I have 4 pools on failover backup.. I can leave these miners and never think about them again... If the pool goes down goes to the next and keeps checking automatically if the original pool is back online, if it is it will switch back. My Hash rate in the pool is exactly what I see locally "literally". I did a mistake and thought there was a software issue with the liberror and I did venture of and test some people cgminer forks but dammm one stuffed me up it was only showing half my hashrate as to what was locally showing.. I had to go back to this one and this is when i found out it was never a software isssue always hardware... I also updated the all the libs and I think its rocksolid I may upload it for people who are interested. Has very small step frequency updates all the way to 1400mhz

So far I have done 5 Gridseeds Vmod3 49.9k with some Mx-2 Arctic on top of the chips Now the miners are hashing at 510k and no HW errors, I think i know what was causing cgminer to play... its not the software if you see my temp setup I now have 28 Grids plugged in and they are all over the place cabling up , down , around, power going through, under around them , BIG MESS as well as power being a bit loose but now good,, everything looks good hashing like machines!!! I also have 5 x 290x Cards hashin I will only have 4 by tomorrow , I will sell my final card from GPU days then build myself a quadfire 290x setup.
Anyways..... I still got quite a fair bit to mod, plus I have 10+ more grids to plug in... I will mod most of mine this weekend if not all that should give me more hashrate to the equivalent of buying an extra blade miner...
I dont know if I am not going to bother with r46 I am actually getting the hang of 139k smd 0402 replacement....
I think i may have wasted my money as I have 16.9kohm smd 0603 better and bigger size will fit nicely on r46 let me know if anyone wants ill let them go for what i bought them and ill post them to your door.
I think i may have modded all mine the original way before they arrive I wish I bought 49.9k 0603 size.... ahh well... I have yet to see someone simply unbridge r46 an chuck a 16.9/17k and freq at 1200 I would like to see local hashrate and see if its 510KH like the 49.9k r139k mod.
Guys there is one annoying thing wit soldering iron , The solder doesnt stick to the iron, it used to in the beginning but now its like oil & water its like the solder trys to run away from the iron... I have tried damp sponge , even as much as shaving the point abit cleaning off all stuck dirt still no good, I hav used flux STILL no good, only thin g I can think of is "that this solder is shit "
Any ideas?
Depends on the material type. But, when you first use a new tip, it is recommended to warm it up to full temp, then tin it by letting the resin core solder melt and stick, then shake off the excess and it's ready to go.Anyways.....

IF you can't get this to work for some reason then the tip is either made of some sort of Teflon like material or you're doing something wrong. Wish I could help more.
Good luck!
What temp are you using or what wattage iron. 30w should be good, temp control do about 230. make sure you have right size tip, too small and itll never transfer the heat evenly so the iron will stick, most people belive the iron not hot enough and get hotter or higher wattage which can burn up the boards/ componets etc.
Yep, that could do it too. Good tip there amex.... I've never had any such problem all these years so......
Hang On Was you in agreement with me??
What you done with the real wolfey
I bought a simple 25w iron, Nicely thin tip but not too thin, Not temperature comtrol , SImple good iron i was recommended to buy for $20.
I have a feeling its the cheap chinese solder I am using... I am waiting on the good stuff to arrive.
Anyway updates CGMINER going harder than ever I finally figured it out ... It was my very flimsy setup Usb hubs on usb hubs dangling next to each other one bump seems to disconnect the 4 port unpowered hub hanging off the powered hub...
I have tightened the positioning down and its been mining non stop no errors... I also replaced the libusb files with my fully developed GPU SGminer, i noticed the lib files were larger so I thought I wonder if the gridseeds is missing some code... anyway I replaced them not sure if it did anything but everything is good now.
I also did a test to same pool, Normal miner vs Modded miner 510kh vs 361kh -- So check this out the 361kh started 2.5 hrs before the 510kh so it had much more accepted shares by the time the 510 was online... anyway 13 hrs later the 510kh is 8,000 shares ahead of the 361
Now I see the difference with my own eyes.... I was watching in catch up and then saw it tied up now its overpassed it.... WOOO HOOO ... And just to make sure its not just 1 miner fuke, I have 26 NON-Modded miners vs 2 Modded Miners & BOTH are between 7 -9 K ahead in sharers from the strongest Stock miner out of the 26... ..Anyway back to my iron problems, I think i will have to wait for the better solder and keep trying to mod this , I cant beleive I have even modded these with the issue I have, I must be ok ay

What you done with the real wolfey
Santor I dont quite get the syntax on the settings for freq
--freq=850 --gc3355-freq=/dev/ttyACM0:900
Why is freq 850 used then 900
Thanks
--freq=850 --gc3355-freq=/dev/ttyACM0:900
Why is freq 850 used then 900
Thanks
--freq=850 is the setting the clock speed for all the Gridseeds.
--gc3355-freq=/dev/ttyACM0:900 is setting the clock speed for a specific Gridseed. If you have multiple, you can set them like so: =/dev/ttyACM0:900,/dev/ttyACM1:850,/dev/ttyACM2:950
You can use either. I don't know what'll happen if you use both though, presumably the --gc3355-freq is more specific and will override whatever is set on --freq. If this is the case, you can set a default clock speed for all the Gridseeds and override a few that need to be set differently.
And if you want to be more specific, you can set the frequency of a specific GC3355 chip:
Code:
--gc3355-freq=/dev/ttyACM0:900,/dev/ttyACM0:875:4
SandorII thanks for the hard work on the miner software. Just updated to the version before this one, and it made a huge difference on Windows. What the Miner said and what the Pool is reporting are Much closer now.
Quick question, on Windows the above would be freq=\\.\com3:900,\\.\com3:875:4 ?
and is autotune going to get that specific when it tunes for best freq??
Again thanks..El

Support for individual chip frequency is added. It’s possible to run regular USB miners and G-Blades on a single instance, because the number of chips is now auto detected.
Binaries (Win, Rpi) have been updated.
I'm still working on a summary like cgminer, almost done, but it feels like I'm reinventing the wheel.

Sandor Rock,
we should all thank him and donate some BTC, I'll be doing it in a few days when I'm done trading some coins

That's awesome. I wish I knew how to code like that. I write tools for my job and automation...but nothing like what's involved in a mining app.
Any other changes/enhancements coming? JSON Config file and failover support?

Guys there is one annoying thing wit soldering iron , The solder doesnt stick to the iron, it used to in the beginning but now its like oil & water its like the solder trys to run away from the iron... I have tried damp sponge , even as much as shaving the point abit cleaning off all stuck dirt still no good, I hav used flux STILL no good, only thin g I can think of is "that this solder is shit "
Any ideas?
IF you can't get this to work for some reason then the tip is either made of some sort of Teflon like material or you're doing something wrong. Wish I could help more.
Good luck!
What temp are you using or what wattage iron. 30w should be good, temp control do about 230. make sure you have right size tip, too small and itll never transfer the heat evenly so the iron will stick, most people belive the iron not hot enough and get hotter or higher wattage which can burn up the boards/ componets etc.
Support for individual chip frequency is added. It’s possible to run regular USB miners and G-Blades on a single instance, because the number of chips is now auto detected.
Binaries (Win, Rpi) have been updated.
I'm still working on a summary like cgminer, almost done, but it feels like I'm reinventing the wheel.

Set it Back to stock mode (without the resistor) the clicking started again and sonounded bad if someone has a soluton for the problem the gridseed was put back together when i tested it so no pushing ore loose parts
Has anybody the same problem ? or a solution hope it is not the oszilator a mantioned ?
Also no bridge tested it with a multimeter

When my gridseeds clicked after a mod I simply re-did the solder joints and that resolved it. Not sure if that will work for all or not, but it's a good place to start. Also, I suppose it is possible to ruin a part by applying too much heat for too long while trying to solder it. I've never run into this however.
So far I have done 5 Gridseeds Vmod3 49.9k with some Mx-2 Arctic on top of the chips Now the miners are hashing at 510k and no HW errors, I think i know what was causing cgminer to play... its not the software if you see my temp setup I now have 28 Grids plugged in and they are all over the place cabling up , down , around, power going through, under around them , BIG MESS as well as power being a bit loose but now good,, everything looks good hashing like machines!!! I also have 5 x 290x Cards hashin I will only have 4 by tomorrow , I will sell my final card from GPU days then build myself a quadfire 290x setup.
Anyways..... I still got quite a fair bit to mod, plus I have 10+ more grids to plug in... I will mod most of mine this weekend if not all that should give me more hashrate to the equivalent of buying an extra blade miner...
I dont know if I am not going to bother with r46 I am actually getting the hang of 139k smd 0402 replacement....

Depends on the material type. But, when you first use a new tip, it is recommended to warm it up to full temp, then tin it by letting the resin core solder melt and stick, then shake off the excess and it's ready to go.Anyways.....

Is there an easy way to check the voltage on them?
I have a multimeter, would that work? if so where would you probe on the gridseed to test?
On my 2nd seed I modded, I used my 10x loupe and looked at it from the side and it looks like one of the pins on the resistor isnt flat so that is probably the issue on the 2nd seed. I hope its a simple fix on the 1st seed as well, cause it was hashing perfectly for 24 hrs and then decided to stop...
It's hard to push down on these microscopic resistors when your soldering lol... I am such a NOVICE.

The voltage, supplied to the Gridseed chips is easier to measure at C42... here marked in black ...:

Do you have to power the unit on to test the voltage, or can you do it un powered? Dumb question, I know lol.
Also with my multimeter.. Would I just touch the black wire from my multimeter to the black fan fire for ground, and then touch the Red to the spot you circled.
I am just keeping my Ground on the 12 V input connector GROUNG...Black...left screw...if you have screws type input...Otherwise the other end of C42 ...the marked with "-" ...outer one ...opposite side of C42 is the best...
Should be in the 1.20V to 1.75V or so RANGE...
Cheers,

When checking with a multi-meter you would use DCV right not ACV? Also I assume you set it to the closest setting to what your measuring, in my case it would be DCV 2..
if this is correct, what I measured is about 1.6... but my unit will still not accept any shares... Any ideas??
no worries for the mod v3 which replaces the resistor NEXT to marking r52 - it isnt r52 btw its just good ref as it next to it - the c42 point is actually an open capacitor connection. the "piece" next to it is another resistor. unless you doing solder bridges - as describe back on page 1 of this thread - you have no worries, as it linked to the vid1, vid0. the mod we do replaces the resistor which corresponds to vid1 open and vid 0 open - the other allow a selction through closing off vid 1 and or vid 0.
Basically dont worry about it. the resistor next to r52 is the one you want the others 3 next to it are extra resistors which wiht modv3 are surplus and do nothing. on back on page 1 or 2 there is a photo showing the resistors labeled wiht there values if you want to replace it for any reason.

Thank you very much!! \o/ You're a life saver.
Guys...don't be fooled...
You are replacing R139...27k with higher value...47k to 51k... NOT R52...
R52 is in the Feedback Loop of the Voltage regulator...
Refer to the schematics...

So I've ventured on my own into this mod, but in one of the gridseed I pulled out something I shouldn't, at C43 it seems, I've tried to understand the schematics to identify it but I'm failing, if possible a little help in identifying what is I need to buy and solder back in place.
Any suggestion really is appreciated.
