After a day of these units running I got sick of the noise of 49 small fans, so I disconnected the individual fans and pointed a box fan at them. Now they are running silently and are only slightly warm to the touch. The only sound is the power supply fans kicking on every once in a while.

Can you post a picture of it with the box fan?

regards,

P.

What's your total power draw?

I don't have a kill-o-watt, but I'm estimating around 8 watts per unit, or 393 watts. Not bad for 16 MH scrypt mining, if I don't say so myself.

How hot is the room they are in or how hot do they run? I have 2 miners with 6 total 280x cards and it is hot as hell in that room. I might order 20 of these to start. What site did you order from? Thanks for the great infor

Well, it's not hot at all. I actually disconnected the wires that cool these little guys and they are still cool to the touch. In fact, I had to turn on the pellet stove just a few minutes ago because it's cold down here. I don't miss the heat and noise created by GPU's, I can tell you that. I ordered from Zoomhash.com, he is totally legit and very helpful.

Great info! Thanks. I just ordered one unit from Zoomhash a few days ago for testing before ordering more. I am looking at selling all my miners to buy some of these up. I have extra stuff from miners so I can do a stand along pc.

It is pretty awesome, isn't it. You need beer to make gridseeds work.

I've been able to get my 48 miners powered by a single windows x64 machine. I was using anker 13 port powered hubs and I found that you can't daisy-chain them, as windows sees each block of 4 ports as a daisy-chained "hub."

Basically, you need to plug each hub into the machine or, at the very least, daisy-chain off the first port. Here is my current setup, minus a few gridseeds.

When I initially plugged these units in, I couldn’t get windows 7 x64 to see the virtual com ports, and found I needed to install the virtual com driver that I found here: http://www.diffpair.com/lightningasic/LIGHTNINGASIC%20Gold%20miner%20USB%20driver.rar

I’m running separate instances of the custom-coded cpuminer with the BTC core shut off for scrypt-only mining. I was able to get that from here: http://cryptomining-blog.com/1165-download-cpuminer-for-gridseed-5-chip-gc3355-asics-with-reduced-power-usage/

I have been able to get about 12.8-13.4 mh when mining with 48 of these units. I’ve been running them for 24 hours straight now with no disconnects, no reboots, and 100% stability. If you are having issues with the supplied controller, I suggest you ditch it and use a computer. If you’ve still got motherboards lying around from your GPU mining days, setup a quick install of windows/linux and run your gridseeds off that.

PICS:

I just love the beer poster.

Also--it looks like somebody has gotten cgminer to work in LTC mode with BTC disabled so you don't need to run cpuminer. Here's the comment:

If you don't want to run a bunch of cpuminers, I have posted modified cgminer sources to allow LTC-only mode: https://github.com/dtbartle/cgminer-gc3355. I have this running on a Raspberry Pi with 10 devices.

great works.
only one problem.lost hash rate. it should be 350Khs per usb miner.

You are right. I had a few units that weren't hashing, thanks for mentioning that! I looked and they were connected to bad cables. Now i'm running 49 units at 16,148 KH. Is there any way to overclock these? Mine are running at 850mhz, and I heard that when people pushed them up to 900, the hashrate dropped. Perhaps a new firmware?

After a day of these units running I got sick of the noise of 49 small fans, so I disconnected the individual fans and pointed a box fan at them. Now they are running silently and are only slightly warm to the touch. The only sound is the power supply fans kicking on every once in a while.

What is the exact part number of the usb hub you are using?

The exact one I bought is here: http://www.amazon.com/Anker-Aluminum-13-Port-Charging-VL812-B2/dp/B00GSLMTQ8/ref=sr_1_1?s=electronics&ie=UTF8&qid=1394057871&sr=1-1&keywords=anker+13+port+hub

There are probably other good hubs out there, but I've always had good luck with Anker products.

many many thanks for your quick "how to".
I'm actually waiting for my LA6M and was afraid to have some faulty controller comming with it.
wouldn't it be possible to use a standard atx psu with those barrel connectors? 12v should be equal but i've no clue about the rest.

I know that some people have contacted the user "cablez" to make them pci-e 6-pin adapters for barrel connectors.

It looks like the hub that is supplied with accessories pack. I cannot find a pic of right now, I know it was in one of the support threads.

Edit- found it

He said they were anker hubs. If you look at the picture it looks like all the plugs are in a line.

'All that glitters is not gold'

Hello !

I know that Gridseed can mine only for scrypt based coins at the full speed.
Which particular coin worth to mine with Gridseed ? I mean to have at least ROI.
