Title: 2x 110,000KHs Scrypt Asic Miner P&P @ ~1000w A2 A2MEGA
Post by: Reversi on July 20, 2015, 03:35:28 AM
2 Scrypt Asic Miners, used for about 2 weeks - Decided to go with another rig.

Looking to get around $1250/ea or $2350 for both

Chip Specs
• Developed on 28nm using very low power design techniques and best efficiency.
• Custom IC package with power bars for low voltage, high current feeding.
• Configurable in daisy chain mode for distributed work with up to 253 ASICs.
• Standard SPI interface with CS pin needed to enclose all useful SDI and SDO data.
• 27 highly optimized hashing engines based on custom ASIC cells up to 1.6M.
• Built-in redundancy architecture to allow for bad engines to be bypassed without affecting mining operation.
• Flexibility to configure the PLL clock and computation performance.
• Hashing power of 1.6M in nominal and 1.8M in Turbo mode.
• Power usage of 10W in typical nominal and 12W in typical Turbo mode.
• Supply voltage of 0.78V in low power, 0.84 V in Turbo mode for ICs.
• No need for special cooling, just regular top and bottom heat sinks plus fan cooling.

The Device Specs
• A Total of 6 boards with 10 chips on each board, Total 60 Chips in a miner
• Size = 51cm—42cm—16cm
• Temperature = Runs cooler than the A1 miners

Now you've started a second thread, selling two A2s instead of just one, looking for more money than the first thread, with what is likely another stock photo, ignoring requests to prove you own the hardware by providing a photo of the units for sale with your user ID and date on a piece of paper?

Here's the original thread:

https://bitcointalk.org/index.php?topic=1128985.0

All this with an account that has 11 posts.

So what happened? Did your original unit spontaneously reproduce? It's a miracle!

You are wasting our time. Prove you have actual hardware or just go away.

I recognize this pic, it's from the Zoomhash website.

Maybe it's the zoomhash guy in disguise. He was probably tired of cloud mining complaints taking over this other thread.

Or may it's the guy who took over philipma1957's coupon for two units. That price for two is similar.

Regardless this is a very odd listing.

I'm the one that used philipma's coupon, so you can take that off your list... ;)  And they don't arrive until tomorrow, so I would at very least play with them before selling (but I have no intention of selling them anytime soon - I want to see how the halving goes).
