Quick update and rough numbers (very rough)
My control board shipped with neptune-rc6 FW
Still a bfgminer checkbox on the 'Mining' web page but it has no effect.
Guess I gotta try and hand roll bfgminer.
They removed the SPI clock and voltage options from the 'Advanced' page
The clock is likely 7-8x faster than default hoopiter cause of 1440 core per ASIC instead of 192
Still 4 die per ASIC, each die now has 360 cores instead of 48
There is an LCD on control board with IP address and hashrate
There is a BRIGHT backlite on the LCD.
(I keep thinking I left my LED flashlight on)
The power on white(really RGB LED) light is brighter still.
If ya lookin at the LCD waiting for it to boot when the white light comes on YIKES!
I tested each box seperately
All ASIC, all die, all VRM checked out.
No idea on individual core health yet.
There was a parade of cores disabling, no idea if it is more or less than 28nm yet
I didn't time the tests ~20-40 minutes per ASIC
I just waited till the numbers looked settled
380-400 Watts @ the wall per ASIC
280-290 Watts per ASIC as reported on 'Advanced' webpage
Roughly 0.6 Watt per GH/s @ the ASIC
I have a plat PSU runnin @ the sweet spot near 50% of rated current,
should be >10% loss in the PSU the rest of difference is prolly VRMs effiency
(plus a few watts to keep the cable warm)
660-670 GH/s per ASIC with default 475MHz clock
~3.3T stock clock.
(I just added them up, not run 5 at once yet)
HW errors between 0.1% and 0.9% average under 0.5%
I predict improvement with better cooling and volt adjust
(If I had bfgminer I'd have a better idea with individual core statistics)
50-55 degree C ASIC temp with ambient @ 27 C
VRM temps between 70-90 C prolly 76 average
The PCIe cable gets a bit warm, I only tried one ASIC @ 500 MHz for a few minutes, it worked
The cardboard box is much improved, triple walled tough stuff
Inside the box is another triple walled origami nest below and above that is doubled toward the outside of box
3 layers of triple walled cardboard
Slight issue with the nest though, it is exact size of cube but fan grill is external and can (did) get bent in, causing it to sound like a bicycle with playing cards in the spokes for motor noise
I retract earlier statement about case strength
(open mouth, change feet)
The strength relies on fasteners and the cube screw holes strip if ya look at them
(might be a good asset for a stripper but not for a miner case)
IMneverHO
She ain't perfect but the ASIC seems solid enough!
YMMV
