bick BOY

The Minion is a very good 28nm chip, just see the test i've done to a BlackArrow Prospero X-3 with 9/10 operative chips:

At this moment i'm doing some mining tests, using a 80 plus bronze PSU with theese configurations (i use this power meter: http://www.amazon.es/gp/product/B001TL36AK?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 ):
Voltage - Frequency - HashPower - Consumption - eficiency
0.7325v - 800Mhz - 655Gh/s - 650w - 0,99 w/Gh
0.7325v - 700Mhz - 635Gh/s - 580w - 0,91 w/Gh
0.7325v - 600Mhz - 545Gh/s - 505w - 0,93 w/Gh
0.7250v - 700Mhz - 600Gh/s - 575w - 0,96 w/Gh
0.7250v - 600Mhz - 550Gh/s - 531w - 0,97 w/Gh
0.6750v - 600Mhz - 475Gh/s - 400w - 0,84 w/Gh <-- The Antminer S3 eficiency!
0.6750v - 500Mhz - 475Gh/s - 378w - 0,80 w/Gh
0.6500v - 500Mhz - 450Gh/s - 330w - 0,73 w/Gh <-- A very good eficiency, sure
0.6250v - 400Mhz - 370Gh/s - 240w - 0,65 w/Gh <-- Awsome eficiency
0.6000v - 400Mhz -  Not tested yet...

a good overall for this old miner, sure (at low hashpower have a very good eficiency!!)

[sidehack]

Yeah, pretty good for a chip intended to run 0.55W/GH top clock, and only delivered 100% off spec and about six months late.

My X-3 are running 700GH at 500-550W. My HEX4M minion boards exist somewhere in limbo between Technobit and Minersource, as do the 50-odd boards I was supposed to be hosting for three different people as of one year ago - never received a single one.

Your X-3 does 700Gh/s at 550w? did you comprobate it with a power meter?

All three companies involved there were scamming bastards

0.6250v - 400Mhz - 370Gh/s - 240w - 0,65 w/Gh <-- Awsome eficiency, better than Spondoolies SP20E

 Odd, my SP20E is getting well under .5w/Gh at the moment - running it at .60 volts while my power cost is high to maximise profit, 864 GH at 400 watts at the wall (measured with a Brand 1850 power meter) putting it at .463w/GH

 I crank it up to .64 volts on weekends (Time of Day rate drops my electric cost then making this the most profitable point of operation), pulling 1291 GH at 710 watts - .55w/gh STILL stomps on your .65

 Due to summer heat issues, the highest I ran it at while testing was .66 volts - 1403 GH at 842 watts - .598w/GH and STILL better than your .65

 Please check your facts in the future before posting such totally INACCURATE claims.

Sorry for that, erased. I did not test the Spondoolies. The SP20E is awsome, then...

Anyone, anything?

[soulistyce]

Im still waiting for my refund since february 

[novak@gekkoscience]

Nice review.  I'd be more than happy to post my own review- we were supposed to have ~50 delivered to out facility for hosting by multiple customers- but unfortunately I do not have access to a telescope powerful enough to observe any of these boards.  Pretty disappointed that multiple customers of ours were screwed by technobit and that they failed to deliver even one board to our facility.
