I have 38 gridseed 5 chip miners. Each is spec'd for 300+ kh/s but I get 325-350+ Kh/s each running continuously (scrypt only mode of course) with conservative clock settings on each of them.
8 of the miners were from the first public LightningAsic batch (gold fins with firmware update capability, but not sure if a firmware update was ever made available by LA; I killed the other two by hooking up to wrong color wires - oops!). The remainder are more recent units (all gold fins, no update capability to my knowledge without modding).
All work great at 750-800 Mhz clock which will yield around 320-350 Kh/s per unit. With modding, these are reputed to go close to 1 Mh/s but these are NOT modded.
More info on setup etc in this thread:
https://bitcointalk.org/index.php?topic=494625.0I have some accessories below that I will give to someone takes the requisite number of units off my hands in one buy (SEE BELOW)
Asking .05 BTC per miner, minimum purchase of 4 miners (not worth my time to pack otherwise, sorry!)
Discounted to .045 BTC per miner for 10-19 miners in a single purchase
Discounted to .04 BTC per miner for 15 or more miners
Shipping will be insured UPS ground ONLY and buyer will pay actual shipping cost with insurance (at coinbase sell price/conversion rate in effect the day I ship)
ESCROW OK. If you want escrow, please PM me with a couple of suggested escrow agents from the escrow list here. If using escrow, any defective or damaged units can be returned/refunded but you must notify the escrow holder within 48 hours of receiving the package and must keep packaging if damaged. I have run all of these for between 3-6 months and have no issues so it is unlikely there would be an issue, but you never know.
Accessories FREE to the **first** person to purchase of 10 or more miners:
Qty 2 - original power supplies and power cables sold with the Lightning Asic gridseeds (there are two supplies for the 10 units that I bought but I believe they can power a lot more in scrypt only mode - I never used these FYI except to test and they put out clean power).
Qty 1 - Lightning Asic gridseed controller - AS IS. NOTE: I applied a firmware update, and could no longer get the pesky gridseeds to hash even though I can access controller easily. I gave up on LA's controller and went to rPi, and all of the units worked great so it is possible the firmware update killed the LA controller. Who knows?? Anyway, it is free so no refunds if the controller doesn't work.
For anyone who purchases 15 or more miners, I will offer my gridseed cage (20 miner capacity) as follows: GAW Miners aluminum open mining cage specially designed for gridseeds (but adapable for other uses) (no longer offered to my knowledge) that will hold 20 miners, power supply, and an rPi. Fully assembled! Optional added cost will be .15 BTC.
