GridSeed 5-chip USB miner voltage mod

[jamieb81]

AH my bad, I thought you needed both tp link + wii

then indeed it's alright

Anyone with an overvolted Gridseed care to test the new per-chip auto-overclocking feature?
https://bitcointalk.org/index.php?topic=554542.0

but its only for the controller not cgiminer or bfgminer . SO is the firmware new firmware for the gridseeds or new firmware for the contoller? and i have a TP link 703n, just not modded it yet or flashed it, where can i get an image for flashing it for controllering the grids???

It will work with Tp-link 703N, just follow the guide on how to flash it. There is cpuminer included, its faster and more efficient at Gridseed mining than cgminer or bfgminer.

nice but the price of an Tp link + wiibox is to expensive to ROI just for that few hasing rate if you do not have an massive amount of gridseeds at home.

If you have just a few, IMHO it's better to buy 1 extra gridseed cheap.

Who said you need to buy a Wiibox? Tp-link 703N can be easily had for $20 shipped.

mine cost about 15 euros only trouble is its in chiense or japense! thank google for google tranlate!

Personally from the guide given here

https://bitcointalk.org/index.php?topic=554542.0

I do not understand how you flash the Tp link nor how you connect that to the gridseeds

finally modded them all.

hows your poolside hash rate??

hows your poolside hash rate??

It ranges from 45Mh to 55Mh.

Well it's been 24 hours. Here are my results.

CGMiner reports no hardware errors, chugging along nicely.

wow nice!

All kinds, its a multipool.

Are multipools even worth it? I see you got over 500k accepted shares in 24 hours. I'm mining LTC and over 24 hours I only got about 5k in accepted shares per gridseed. Just wondering if I should which.

Thanks!

It's a gamble. Hell, it's all a gamble. I prefer multipools because I tend to see better results. YMMV.

Hi,

could someone tell me if this is the correct place as to use Wolfey's 5v mod? I tried it and fan does not run when I solder it there.

PS: I unsoldered it and just holding it in place now because I did not want to make it run and maybe soldered on the wrong component.

I make them run fanless now as they are not yet voltmoded but in the future I will.

Otherwise I'll just put the fan on a 5v rail of my PSU

[Cablez]

That is the correct side of the correct component for 5v operation.  I am not sure why that did not work for you as it worked on mine.

Hmm that's weird then. I'll try on an other pod to see if it also gives problems. If it does then there must be something with the connection of the

solder to the board or so

Did you have the usb connected after you soldered it to test the fan? If you have a multimeter it would probably be less hassle to just pull that out and check to make sure that you are getting a voltage there.

Working now, did not have a multimeter.

On second pod worked right away, I guess on first one was a bit short on solder or something.

Thanks guys

Good news ... never soldered a thing in my life and successfully modded one of my GS units with a 49.9k resistor on R52.

I decided to pick the poorest performer of the bunch in the off-hand, (assumed likely at the time) chance I'd screw.

But not, even with smracers cgminer.conf snippet ... I can't set individual speeds for my GS units!

HELP!  Can someone PLEASE post an example cgminer.conf file with individual speeds?  =\

Thanks!  Hope someone helps.  =)

EDIT

If you can't use the gridseed-freq option ... you need to source a different version of cgminer.  FIXED!

Man ... It was some rough stuff soldering stuff this small on my first attempt.  I had a spare motherboard lying around to experiment on, but I only experimented maybe a few minutes.  Couldn't help it, was like LET'S GET IT ON!  lol

The more I read you're experiences, the more I like the hot air station.....never used one, well after my glory days on the bench in a commercial facility stuffing pcb's...
Sounds nice! Cool! Another toy!

must admit my previous soldering irons were cheapish ones - mid range. no temperature control. So i had a bunch of different watt soldering irons. Not to mention different tips, some fitted but none fitted all the irons so annoying. And i had several soldering irons blow on me too, heating element fried type thing. cant cant it or even get new ones, so id been looking to get a temperature controlled one for a while, and when the cheap hot air station i had - used mainly for heat shrinking tubing - went as well i decided that i was gonna get new and upgrade. Then the bitcoin fase entered and i started modding the the sticks, after doing many resistor swaps i thought hot air station got to be easier way to do this. bit of online research and invested in the whole deal complete reworking station. has temperature controlled soldering iron - arrgh so sweet itself  - air hot mounted gun, temperature probe and surface pre heater too. Plus it has several arms for irregular PCB shapes - which turned out to be a bounes for the round PCB of the gridseeds. the only thing it was missing was a light and magnifying glass. But that nothing. Oh for those wondering its aoyue. Good name, plenty of spare parts. I thought it was American so i was disappointed to find it was made in china. BUT i must say its one of the few made in china that have quality, you can see straight away from the build quality of it.

here it is : http://www.aoyue.com/en/ArticleShow.asp?ArticleID=465

Not looked back. For those that are more into doing it with soldering iron, or dont want to invest in a hot air station, i can highly recommend a slot type tip or even better soldering tweezers. that way you can apply the heat to desolder and solder at both points of the smd resistor at the same time. I spotted one and nearly got one myself but ive not used one but think it would be almost as easy as the hot air.

Seriously wolfey2014 get one great toy! JUST get a quality one - same goes fro anyone investing in a soldering iron - itll last longer more reliable and constant, id say aoyue, or weller, there others as well but i can think of the names of them now. And for those going soldering iron route make sure the iron has interchangeable types the type the slide over the heating element. Provides better heat transfer.

Hot air gun is amazing! I got a cheapo one (Yihua 858D). Prob fake but it does the job. My only issue is that I don't know what temp to put it at or how to properly remove SMD components :/

I did one the other day i found the solder started to give at around a temperature of 230- 240 on the hot air gun, i also plugged in my temperature probe to check the temperature at the surface of the SMD resistor, and it read 230, just as i touched the resistor with the probe it slid out of place across the board. thankfully i didnt knock anything else - still got a bit of a big nozzle on for 0402 series , new nozzle in post. Oh all temperature are in Celsius.

And soldering SMD is totally possible with soldering iron, and this guy makes it look like a walk in the park, serious skill!!!

Okay okay..I believe, I beleve!.. I'll mod 10 of your pods plus some cash for a complete hot air station in return.
Butt!.....
I am still going to do the mod with my temp controlled Weller pencil iron and 1/4W axial resistor, and my Movie Star skills!
Just getting this discussion back on point,,, in the first place!
PM me if you're want to take me up on this deal.

Yo Jamieb81,,,
what you doin to yo pod?
the connections I show for the 5V USB mod, are correct....
figure it out....it's probably something you're doing wrong or overlooking....
hit me up via PM if you need further....
