I've successfully migrated our SP30s over to our 258V supply. Performance is up.

Device ID	Hashrate (cgminer)	AC power usage	Top PSU lim (DC)	Bot PSU lim	J/GH
Mine	4527 GH/s	3024 W	1362	1367	0.668
Wanna1	4476 GH/s	2928 W	1345	1351	0.654
Wanna2	4459 GH/s	2960 W	1344	1347	0.663
Wanna3	4470 GH/s	2992 W	1349	1349	0.669

Thank you for the review. It seems that the competition is spreading lies about SP30 power consumption.

If you are talking about the knc newsletter, it is badly researched.

0,57 J/GH - KNC Neptune - 1950 watts at 3400 GH/s (reported average)
0,62 J/GH - Bitfury BF3500 - 2200 watts, 3500 GH/s (stated, unconfirmed)
0,76 J/GH - Spondoolies SP30 - 3200 watts at 4200 GH/s (reported average)

It also claims bitfury be 3500 does 0.62J/GH, which not even bitfury themsleves claim (it is ~0.775)

Edit:
Most of the reports I've seen of the 20nm competition are over 0.6 W/GHs
We're overclocking the extreme slow corners 28nm ASICs we got. The power ratio for October units will be 0.55 W/GHs

For those of you who don't understand semiconductors: You do not get multi lots and multiple wafers of an "EXTREMELY SLOW CORNER." Stop letting Guy take advantage of your lack of knowledge. Given the orders which they have in the pipe and what they have communicated, I would guess there are AT LEAST 12 lots (25 wafers per lot) in the pipe. You do NOT get 12 lots processed systematically to a slow corner unless you deliberately asked for it.

You're welcome
