Why would someone buy a gridseed miner right now at these prices?  I'm not understanding how it would ever be profitable.

Why would someone buy a gridseed miner right now at these prices?  I'm not understanding how it would ever be profitable.

For me it was about reducing my power footprint, time spent baby sitting GPU's and heat. I've not got 20 grids on a single computer drawing around 180 watts fully operational. Heat isnt an issue at all (I've even disconnected the fans on the grids) and I have not had to baby sit them at all other than changing the version of cpuminer when it was patched for single mode only.

I managed to sell the GPU's I had (which amounted to a bit less hashing power I might add) for more than enough to buy those 20 grids.

Which miner and what price are you talking about? They have several miners you know.
I think 240USD for a 400Kh/s miner is pretty fair.

they have different versions? Are you talking about the single chip version?

There is a theory that you can run up to 127 gridseeds per USB controller.

I think it's practical to manually set the limit to a lower number unless you actually have 127 units to test this on.

The next step is to then try and see how many USB controllers your system or motherboard has, otherwise you could just buy a PCI USB expansion card, then you are limited by how many slots your motherboard has.

For most people, this should not be an issue. You could theoretically run 240+ on just one motherboard, on the assumption that there are two separate USB controllers (north and south? or whatever). And an additional 120 per PCI USB expansion card.

The next issue is what OS to run, and RAM requirements. Litecoin BAMT 1.3 runs on less than 1 GB of RAM mining 5 GPUs using cgminer, and it loads on a USB flash drive as well, saving you the cost of a hard drive or SSD.

thanks, that helps.

Isn't gridseed launching a 1TH/s BTC miner soon?
Anyway what do you think about the price? Would like some input since I'm planning on buying something to replace my GPU.

Can you quote me the source? I think the gridseed 5chip is nice, especially if you have high electricity cost. $/hash is not that bad after all

Ok, I agree $/hash is only like 40% higher than a GPU. And a GPU draws 140% more power.

Might be confusing LightningAsic & Gridseed. I thought LightningAsic created the Gridseed miner..
I was reading in their thread that they were also working on a BTC miner:

88 Gridseeds Total @ 10 watts each = 880 watts @ 12v = 73.33 Amps

Adapters/Splitters/Barrel Plugs Used:

Edit: only use these as examples. In my final version I upgraded all connectors and splitter to 18 AWG wire. This is very important you could start a fire.

Any critiques of this setup?

HI

anybody knows if this real ?

Blades design for gridseed ?

[kocur]

where can I buy just chips? and price for one? .)

[crypto.lawyer]

Does anyone know if the 400mhs version is just a firmware update?  Or is that a different model than the 300mhs miner?

A lot of people pay for power.

Also current leaserig weighted average is .010 / clevermining .09xx 30 day / litecoin .06xxx?

Even hosted/paid power these can turn a profit.  I prefer GPUs $160 for 500Kh/s low noise.

Kh/s

Do you have a source where you saw a 400Kh/s version or was it just a reading of 400Kh/s?  Depending on the method of speed rating my GS go from 0 - 2.1Mh/s or sit at 326-350

Hi all.
Anyone knows, where I can buy the Gridseed items in Germany (I only know this shop: https://www.msp-home.de).
Thanks

[bamsterdam]

Dear forum members

I am thinking about buying 500 gridseed from gridseed.com in china. I heard from them that you have to arrange the transport yourself. I wouldn't know how to do this, has anyone has experience with this? I live in the netherlands

Thanks


and this is a company in Germany that gave me a pm since I was interested.
This is his website :

this reminds me folks replacing their gpus with asicminer usbs

Does anyone know where I can get just the GC3355 chips?

[forevernoob]

Does anyone know where I can get just the GC3355 chips?

Have you tried contacting Gridseed directly?

[mazedk]

Does anyone know where I can get just the GC3355 chips?

From what I have read, its not possible yet.

I would guess when they get ready to put out gen2 chips, they'll pump out their last gen1's for customers.. maybe?
