[GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher

Sorry to bump an old thread, but does anyone still have any gridseeds for sale? Shipping to Florida

Try Aliexpress.com, search for Gridseed.  Just got one, hope to do it again in a couple more weeks.  Really, I got what is supposedly a used G-blade for $62 including shipping.  Got it in about a week.  Everything tells me it's from 2014 but it doesn't look used, might be new old stock.  Very happy with it so far, glad I didn't get some newer smaller stick miner.  Without pushing it hard it's been doing 4,496 kH/s for maybe 18 hours so far, running at 700 MHz.

Things from Aliexpress, especially miners, are always used. I've bought several blades from them and even though they may look new it's probably just cleaned out. $62 isn't bad but you'd probably have been able to find better deals even on the forum. IIRC these are supposed to run at 5.5MH, guessing you're running your blade under stock clock.

Hi leo, just wondering  if there is any real value in setting up aG-Blade or gridseed setup in 2017?

Are there any decent scrypt based alt coins going at the moment?

Also can the GBlade mine other scrypt based algos? like neoscrypt etc.

Thanks

At current pricing for LiteCoin (the ORIGINAL Scrypt-based coin), it might be profitable to run a Gridseed right now if you have fairly low electric cost.

 Many pools (like LiteCoinPool) do merged mining and use those profits to pay your pool fee for you (LiteCoinPool has a LISTED pool fee of -3% (yes NEGATIVE 3 percent) due to merge mining).

 Keep in mind though, that the 5.5 "official" rated Mh/s of the Gridseed 80 blade was really a pretty strongly overclocked setting (750 Mhz, vs 600 or so "stock" on the older Orbs), and while the mining chips themselves were quite comfortable with it the power circuitry was notorious for FAILING a lot when pushed that hard on the "80 blade" units.

 I can't speak to the later "GBlade black" type gear, as I never owned any of those units.

My first ASIC miner was one of these at $62 because it seemed like pretty good bang for the buck.  https://www.aliexpress.com/store/product/Free-shipping-Gridseed-G-Blade-ASIC-Scrypt-Blade-Miner-5-2-6MH-S-100W-Scrypt-Blade/227686_1834929913.html?spm=2114.10010108.1000023.13.6fYgra

It's OK, it's earned me over 1/8 of a Litecoin in the time I've been screwing around getting something running for doing Bitcoin.  The original fan is too loud and needs to be replaced, need a 92 mm 12 volt fan.  As long as you're just doing Scrypt the power usage seems fairly low, I've heard of running them without fans for that. Mine came with cut off pigtails for power, I just spliced them into a computer PSU I had around.  Needs 12 volts.  Running at 750 MHz with cgminer I see about 4,600 kH/s at litecoinpool.org

Sorry, I haven't figured out how to post pictures to this board.  I don't know if the retrofit boards Sidehack/Gekkoscience is working on for the Antminer S1/S3/S5 series might fit this but they seem close.  It's an impressive pair of heat sinks anyway.  I haven't measured the power consumption.

 Don't try running them without a fan, but they don't need a real high power fan. Pretty much any 92mm fan should push enough air to keep them cool enough.

 DO NOT TRY TO DUAL MINE with one of these units - it WILL fry the PS part very very quickly.
 They were not designed for mining SHA256 on at all, even though the CHIPS are capable of doing so they eat WAY too much power than the regulator circuitry can handle (that part is MARGINAL even for just Scrypt mining).

 Any source of 12VDC that's reasonably well regulated should be fine - lot of folks ran these off PCI-E to Barrel adapters.

 As I recall ballpark 40 watts per side at the wall was the normal consumption of these, running on some 12V bricks of unknown efficiency - might see more like 30-35 at a guess running them off a Bronze or better computer PSU.

Hello

I am a newbie trying to make my first steps mining LTC using a Raspberry Pi and a Lightning Gridseed 5 Chips .

I install gcminer 3.7,2 and As I can see gcminer  says

but the hash rate reported in the pool web page is only 10 KH/seg .

Pls can someone explain me the difference between the hash rate reported by gcminer and the value I get in the pool web page.


I tried to test some gridseed-options like freq=850 and chips=5 but when I tried these values the hash rate I get in the pool is always 0.
I only get theses 10 kh/seg without any gridseed options.


Pls is there anyone who can help me?

Thanks you very much and best regards

Horacio Merovich

I have some virtually new ones worth putting on ebay as I am in the UK,what would they bring

30-40 USD each would be fair considering the hashrate. I don't know the conversion to GBP though, they may be going for more right now but considering the exceptionally slow ROI you would get on these it wouldn't be a lot.

You could always search for some already on ebay and Aliexpress to see what they're going for.  On ebay at least you can search the completed auctions to see what they sold for.  Some people ask absurd prices, those won't sell, but by looking at what did sell you can get a better idea.

ROI, I'd guess they'd make less than 3 cents a day for the 5 chip, but some people think they're going to get rich because they don't do the math.  Or use one of the online calculators.

can anybody explain how to solo mine to my local wallet using Sandor's scrypt? i am mining on windows 7 using this CPU miner .bat file. it recognizes my gridseed hardware, which is great. however, it sends the hash out to a stratum server. i need that hash to get sent to my local wallet!

any help on this is GREATLY appreciated!

thanks
