Topic: [CLOSED] Group Buy #31 ASICMiner Cubes 0.35 BTC 28-38GH/s - page 7. (Read 50281 times)

I no longer have any backplanes. They are all sold. SSB

12/31/13 If anyone from AsicMiner reads this thread, please contact me about where my multiple orders of cubes are or when they will ship. The update is that I have placed multiple orders for cubes over the last 1 1/2 to 3 weeks and am waiting for delivery of them and/or tracking numbers. I have issued some refunds and am waiting on inventory to fulfill orders and/or warranty replacements. I have a few hubs for sale and a few backplanes if anyone is interested. SSB

Corsair CX750M works for 2 cubes.  One in overclocked mode.  One in low regular mode.  I have yet to troubleshoot the one that runs in low clock mode to verify whether it's the blades, motherboards, or the PSU.  It's giving me partial xxx's.

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.

This one works excellent.  Can run 3 cubes on high (and small CPU) at once.  It is 80 plus gold rated (energy efficient) and I have seen them on Ebay for about $110. Comes with nice modular connectors. Whisper quite and runs cool.
I have two of them.

First off I got my 3 hubs today thank you.  You have been a very good seller to me no complaints and the 4 cubes I purchased all work I sold all 4 and mad a few bucks. Posted a trust for the hubs.

 My thoughts all 4 cubes failed to work on 3 different  hi end seasonic psu's  . I happen to know that many corsair psu's are clones built by seasonic and that they are exactly the same.  So I would tell very one to not use Seasonic Platinum psu. or sea sonic gold and the corsair that are rebranded versions .  btw this is about 12 models of psu.   I had a cheaper model work fine from fsp it was an 800 watt model.  It allowed all 4 cubes to work.  I also had a problem with fans I put in a noctua hind 25 dollar fan and all 4 units buzzed when powered done.  I switch to 10 dollar silverstones and the power issues stopped.  so  these units are tricky.  If you have a good one please give us the make and model of your PSU.

the fan below moves enough air for low clocking and is quieter

12/28/13 Cubes have not arrived for all preorders placed. I am issuing refunds to all that preordered and request one via pm. Please state your tx id, amount paid, cubes ordered, and a refund address(preferably the one you sent payment from). Refunds will be processed in 96 hours or less from time received. I have not received tracking numbers/shipping information from AsicMiner as to when the cubes are to be delivered. This is why I hate preorders. Last preorder shipped on time. This one was a complete disaster. If you wish to remain on preorder list, do nothing and I will ship as soon as I get them. A refund is always an option until I ship your preorder.
  As to current cubes already shipped, I have not received any warranty units to date. I have shipped numerous individual mini blades, bottom main boards, and entire cubes at my expense. I have no more inventory in hand to ship replacement parts. Hopefully next week, I shall receive my prepaid cube orders to be able to swap out parts and or cubes. If you are having problems with your cubes, please pm me and I will try to work something out. Any new orders of cubes(once they are in stock) will be 0.79 btc each due to cost of swapping parts and time involved in dealing with problems.ANY FUTURE ORDERS OF CUBES I CAN ONLY GUARANTEE THEY WORK IN NON OVERCLOCKED MODE AT A MINIMUM OF 30 GH/S.

I've run through 8 and have 8 more shipping. Only one had 'x's on high and then only 2 boards with 1/2.  Still got 35gh/s on it.  All the others ran at 38.4xxgh/s non-stop 24/7.  I'm using corsair TX850's to power 2 at a time.

I think we are dealing with some very cold weather and rough shipping.

with so few companies with a product to deliver.... asicminer will continue to get away with this crap....

I have same problems

I got 1 cube as well from Canada .
This is bad product.
Clicking from time to time.
Random resets, with clicking constantly noise, and second red light blinking.
Everything was fine in the first 2 weeks, now even on low clock i got issues from time to time (hour to hour).
my powersupply is fine 850 modular,good brand.

1 cube, on 1 corsair 750,   nothing else using power from the psu just the cube....    this product definitely does not do as advertised.....

I am seeing same issue. 1 cube 1 CX500 PS. click high, cube slows and chips begin x'ing till all x'ed. have to turn off, wait a few mins, then turn on to bring back to low speed.

1 cube on 1 PSU.

Do you have only one cube on a single power supply? I had 3 cubes on one 850w power supply and they would have the same symptoms.

When I click on high clock, the cube slows down and then it's all xxxx. I then have to wait like 10 mins and restart a few times. Thn randomly after a few restarts it works. Just throwing this again if someone else is seeing the same and there's a solution.

I have to start all mine on low speed and once they are running, log into them and hit the clock button to high but not save that settings just in case I need to power cycle later. Will continue running in high clock. If I start them in high clock, they never start. They just x out. Using Thermaltake 850W power supplies.

My cube doesnt hash on high either.

Yeah quite honestly I'd like a refund if this cube won't hash on high which it won't along with many other people it seems. Is that possible?

Seems to be a trend...  I just got my unit, it came in a mess.  Every card out of alignment, every heatsink loose.  Main PCB is scraped along the edge where it was jammed into the case, fortunately it only hit the untraced copper.  One blade pcb has a soft corner (smashed or dropped?).

Won't hash on high setting using a Corsair CX750.  Swapped it out with the same model CX750 that's been hashing fine on another unit - same results.  Will get it taken apart to find the bad board.

SSB, does friedcat warrant these if they don't hash on high?  Running 32.3 on cube, 30 at pool.
