Where are the specs!?!

Doesn't really matter what the specs are if he's not going to share...?

Wtf is this scam? Its been 3 weeks with no info

Not quite the same (7 months little to no info) lol

Yea is funny how the process just keeps repeating. As if theirs some kind of pattern to it😜😎

I am so curious and want to know what is the reason for the vawe form of the cupper tracks on the pcb.

It's to keep all tracks the same length. This is required for buses that have many parallel signals so that all data arrives at the same time.

Man, no offense, for 3w you cant count at power plug..

He is actually talking about Kill A Watt

http://www.inspectortools.com/Kill-A-Watt-EZ-P4600-p/kawp4460.htm?gclid=CKeYtrG02LkCFWJp7AodVC8ABA

A device you plug your FPGA into and while it is running you can accurately see the watts being used.

Then you take a picture of your FPGA plugged into the Kill A Watt and prove you are only using 3 watts.

he is probably running it on a lab power supply and that will use more than 3w on its own so you wont get an accurate reading from the wall

Also, not a scam even if that were true.

Just saw it 22kh so basically useless lol. 22kh x 4 sticks still useless.

I dont think so, a 4 stick device would deliver about 100 Khash/seg, with 15 w power, 10 devices would deliver 1000 Khash/seg with 150 w power or less ,performance 1 Ltc/day -----> 2€/day and 3.6 Kwh/day = 1.3€ clean at day , 0.13 each one, 0.0013 BT/day/device , 0.039/month /device

I would pay, 0.12 BT for each one with 4 sticks

Its a beginin

What kilowat, lol, its about wats, 300 mA on 10 Volts..

I wanted to see the meter reading at the outlet instead of you just saying what the power consumption is...

Max hash rate on raw scrypt with external ram is ram_transfer_freq * bus_width / (1024 bits * 2048 rw). With special tricks can go more than double. For example, a ddr3 stick working at 350 mhz will produce raw 22khs, as in this basic design:
https://vimeo.com/m/74955720
Power consumption is 3W. Costs less than 1.5$/khs.

Show me the Kilowatt reading, please.
