SD Boot fixed it for me.

As i understand the SD card must remain inside the rig forever..?

For now.
Remo will contact you with experimental SD recovery to try to fix the emmc

I would also like to try this please - I'm still waiting for Barbara to send me RMA shipping info, so might as well try this out in the meantime - if it works it will save me having to send the unit back & fight with DHL over tax & import duty again

Give an inch take a mile...

Having the ability to switch voltage settings by time of day is nice, but how about a way to automatically adjust voltage settings based on which pool connection is alive? If I'm renting out my SP20 at a rate significantly higher than BTC (mining WestHash at a good time for instance) then I might want to optimize for more hash rate, but when I'm not renting out I want to optimize for power.

This is not essential; it is just a "would be nice" addition. Yes, I know, feature creep.

I've ordered today!
That's like getting into mining for the first time again Grin

.

Hopefully ASIC mining will be fun as GPU mining was.

Well, I was more interested in having the pins come out on 16awg for a few inches, than having the three splice together into a single line. of a heavier awg.

I've done this before on some of our early prototype PSUs. It works okay. It's not worth the time it takes to put it together, though, in my opinion, especially if you find a decent source for 16awg PCIE cables that are long enough etc.

I thought the original spec from Molex for the pins in the PCIe socket was the same as the original ATX socket, and I thought that was 5 amps. Does anybody have a more accurate recollection or specification on that? At 240W, that's 20 amps split across 3 pins, and also 3 wires. That's just shy of 7 amps per pin/wire, assuming all is well balanced.

It was originally 8 amps per pin, limited by the Molex connector, for 288 W. More recent PSUs (since 2005) are required to use 11 amp connectors, for 396 W. This assumes 3 pins for each of ground and 12V. The PCIE spec only requires 2 of each to be connected; although many PSUs include a 3rd of each, it is not universal.
http://www.tomshardware.com/forum/274631-28-power-spec-power-plug#2674391

The original PCIE power spec as a whole only specified 2 amps per pin, or 75 W total. The 8-pin revision of the spec specified 4 amps, or 150 W total. This is much less than the specifications of the individual components of the connector, which is why we disregard those limits entirely.

5 x SD recovery attempts

5 x 'xmas' alternating leds

0 x recovered

kinda sick of babysitting this thing - the SP20/SP20E didnt miss a beat, so wtf is wrong with the SP30.....again?!

Same problem here, but with an SP20E. It just disappeared from my network, stopped hashing & became inaccessible via ssh, gui or myminer.io. Tried the same as you above as well as the boot SD - nothing. Awaiting response from Barbara & tech support...... Sad

If you get xmas lights, this means that the SD card operational.
this means that you should be able to use the boot-sd (even if the mmc got corrupted) and run from SD-card
Even in the x-mass state the platform should be available via SSH.

That's the problem - I no longer get the xmas lights. I'm on skype now waiting for a reply from spondoolies-tech support 1 Wink

EDIT: They just went offline........... Sad

i havent tried the boot method yet this time. although it didnt seem to help the last time this one failed after a brief power cut.

as to replacing management board/emmc? i am confident if its relatively simple.

Give it a try

why is there such a big difference between frequencies of the loops:

Code:

the loops that get hotter (the back ones) get clocked higher and use more power

another power cut - another non-responsive SP30

Did you try the boot method? Maybe the mng board got corrupted somehow and it just needs a uSD card as boot medium. Happened to one of my miners in Advania.

It seems like a problem with the management board, maybe the emmc. If you're ok replacing it by your own, contact support@

dps2000bb is very nice psu! the 2.88kw looks good too but is too noisy

You run your rigs at home? Only reason why a PSU would be too loud, right?

The voltage and draw on the SP20, is 3280ish watts per plug or per pin?

Trying to see what 14awg wire will handle

14 awg will handle more than the pins or connectors Housing them.

Well, I was more interested in having the pins come out on 16awg for a few inches, than having the three splice together into a single line. of a heavier awg.
