Just placed an order on the website for 6 units. Please include
one of the ATX-DC breakout boards.

Thanks!

Awesome!  Will place an order on the web site later this evening!

100 more chips for me.

Transaction: 1KbT4MkxVDZDQCwMA9kpqCHS9jnEU9MKaM

Now I really have to finish my PCB CAD...

Thanks!

Ready to order another 100 (or more) depending upon hearing
from my PM.  This is great stuff...

Any updates?  According to a previous post, Reel 3 open, but the payment deadline has passed.

Sounds useful, but I would just use the well-known abbreviation of {HW} vs. {HARDWARE}

After messing around with a bad cube and swapping around power supplies,
I finally have a reasonably stable setup.  I found that my new Corsair 850 has a
weak or blown PCI port driver so I can't use both of the PCI outputs for
powering two Cubes. Runs one just fine.   Unrelated, one of my Cubes will sometimes
power-up in all "X" mode.  After a few extra power-ups (hot or cold, didn't matter)
and it runs for days (so far).

I use one instance of mining_proxy.exe running on Win-7 and
I have no efficiency issues. Blades are 99% efficiency, Cubes
at 97+%. Each Blade and Cube has its own worker, that may be what makes it
run correctly.  I would like to use a Raspberry Pi to replace the PC as a proxy, but not
if I need multiple Pi's for my current rig of 3 Cubes and 4 Blades.

Would be interested in a small quantity. Interested in QF blank board + Vregulator,
are you talking about just the VRegulator chip or the chip + components? As part
of a "kit" of components or soldered to PCB? I also have BF chips on order, so I don't necessarily
want or need the chips unless yours would show up before mine (paid Reel #1 GB).
Of course, having extra is fine, but not if that delays getting the kit(s).

Sent payment for 100 chips from Reel 2:

PM coming

Thanks!

Can order another 100 from Reel #2 to go along with the 100 from Reel #1
already paid & confirmed. LMK if Reel #2 is a go.

Fair enough! Bitcoin sent for 100 pcs.

Ready to order 100 chips from first delivery of this GB.

Can send BTC when it's past the "discussion" phase.

Am also interested in a DIY multichip board.

There is no spec for the "max wattage" per 12V lead.

If you can feel any noticeable heating of your 12V leads, you
are already on the edge.

No assurance that a good brand PS guarantees anything.
My new 850W Corsair has been my least reliable.
If you're building a world-class datacenter, you can do a statistical analysis,
but for a desk-full of hardware, it's a mistake to draw conclusions
from so few datapoints.

Generic PCI-E splitters are light gauge and will overheat
and/or fail.  Most ATX PCI-E leads are longer than necessary, so if you
can scrounge up the extra connectors (from other donor power supplies),
you will get better performance if you shorten the leads to the minimum,
and soldering together a pair of PCI-E cables for each Cube. Or, cut up a
useless PCI-E splitter and solder that directly to the ATX supply PCI-E leads,
making the splitter leads as short as possible (i.e. 3-5 cm)

I have 3 cubes, one is acting up (all X's) but I have been doing a lot of fiddling
with power supplies and good power is absolutely required.

I have one cube running on a generic ~600 W ATX supply, with a single
PCI-E harness. At first, it went through a splitter, which lasted a couple of days until
it melted.  Then, I soldered the splitter ends directly to the ATX supply, which
now runs great, nice and cool.

Cube #2 is wired to a 1000 W HP server supply that also powers four ASICMiner Blades.
It's been working flawlessly.

Cube #3 is wired solo to a new 850W Corsair RM850.  This turned out to be the weirdest of the
bunch.  The RM850 has two independent PCI-E harnesses, which each have a pair of
PCI-E connectors daisy-chained.  But there is apparently a defect in this power supply
because the Cube won't work on one of the harnesses, even though the
power supply works under other test loads. It works 100% using the "good"
PCI-E harness, daisy-chained to both Cube PCI-E power ports, but won't work
when plugged into both harnesses.  There is no noticeable heating of the PCI-E cables
when the Cube is powered by a single harness with the Corsair, and noticeable but
modest heat using the generic ATX supply.

One of my Cubes has intermittent ASIC failures and start-up problems, but that does not
seem to be power-related.  Believe me, I've tried everything. SSB is working with me to
get that issue resolved.

All my Cubes are set for overclocking, and (once you have 100% good power) that
does not appear to be related to any problems.  I also have a supplemental
200 mm fan exhausting air out the front of each cube, just to be safe.

These are some fussy miners, but many of the problems can be tracked to
system power supply issues.  I'm glad that I happen to have had enough
different scenarios to test out in order to help diagnose and troubleshoot
what does and doesn't work.

To clarify, the start signal is on the 4th pin, and it can be grounded to the 3rd or 5th pin, which
are both ground (among many others)

I also have not heard from SSB since the four PMs I sent since Dec 21-23.

I went to the expense of having my latest cube sent via Express Mail and
it arrived promptly and safely, however it is DOA.

Tried a few things but it's not hashing.  Had two loose screws inside that were tightened
up, which seems to be typical for these things. The other two cubes in my rig are
A-OK.

I'm sure this has been mentioned before, but I have found it easier to
reconfigure your subnet mask from 255.255.255.0 to 255.255.254.0,
which makes accessing the blade or cube default configuration page
much easier. Change the subnet mask on your router once and from then on you can
reach the default page from any browser on your local network, as well as everything else on
your local net, blades, cubes, proxies... Working flawlessly for me for a week or two.

Will send a PM in the AM, ordering a Cube for USPS Express Mail delivery.

I would also like to know when more cubes are available.  Would also consider
more blades at a lower price.  Not trying to start any kind of argument, but my rig of blades
and cubes MH/Sec runs over 3:1 per cube/per blade.  Will watch future developments
eagerly.
