I've had a few cubes that go all x's on me when the power turns off or when updating a setting in the config page. 

After getting them to turn back on or go all O's again seemingly at random I think I have found a way to replicate getting them back to O's. 

If your cube is all x's and you know the PSU is good/has the amps to be able to run a cube at high try this:
 
  1) Turn off your PSU
  2) Unplug the ethernet cable
  3) Turn your PSU back on
  4) Wait for the Red LED to finish its initial startup blinking sequence (its just a few seconds long)
  5) After the last blink wait a second then plug the ethernet cable back in.

This seems to work for me on a fairly consistent basis.


Another tip.  If your cube is well powered and still resets all the time try taking out all of the blades and taking off the heatsinks.  One of mine had a grey punchout left in it between the heatsink and the grey heat material causing a bulge and air gaps between the two.  I'm not saying this is the only reset problem but it has been running for a few hours without a poweroff on high after that got removed.

ASICMiner 8 Cube rig.  About 310GH/s.

Yes it is a dedicated 20 amp circuit that had the killiwatt on it.  It was beeping from time to time as it was hitting the 15amp warning on the killiwatt.  Its no longer plugged in, I just wanted to check the draw from the cubes.

I have two cubes on a 15, another one on a different 15, and five plus the switch on the 20.

I am definitely keeping an eye on things, and thanks for the warning.

Yea, I had five on high through this Kill-a-watt.  1718watts/5 is about 343.6watts each.  I would use both cables to be safe.  I did run two Cubes through one PSU for a bit and the PCIe power cable got much warmer than using a dedicated cable for each plug.



I'm also using the CX750M's on all Cubes.



I did have a problem with two cubes going all x's on me, had to switch out a PSU plug to another circuit.

Got our cubes up and running.  Thanks Crazy!

@wiredmine  It could be, the wires from the psu's gets really hot.  If you look at the plugs its just bridged from one plug to the other.  If I get another set of cubes I wont be getting these psu's again.  I will most likely get a more expensive corsair maybe the cx750m  59$ on newegg after the rebate.  Those have a seperate set of wires for each pci express 6pin plug.

Also yea I bridged the green wire plug to a ground wire.  You can see the yellow wire loop in the picture on the left one.

Fans are pretty quiet, looks like an easy replacement.  I had to reseat the boards inside the cubes because they got out of their top grooves in shipping.  The one fail is the stickers they put on the middle of the fans... those flew off 30 seconds after I started them up.



You could strap a fan to the exhaust side of the cube no issues but there is no room inside for anything.

It should.  I thought the 600's I got would be fine.  The two PCI express 6pin plugs get a bit warm so it might be tripping because the gauge of wire is to small.  If I get more cubes I'll try to get a PSU that has 6pin PCIe plugs on different rails.

I'm running two cubes with a 600w psu on each.  If i set them to high one will trip the psu off right away and the other takes a few hours but turns off as well.  I'm running them on low so I don't have to keep on top of them as much.

I got one of the two hubs running.  All 48 on the running hub are hashing away. 





Thanks CrazyGuy!

My window is south facing.... yea not ideal.  Having the miners so close together doesn't seem like a problem, they don't get that hot.  I run bfgminer and haven't run into the issue you describe.  They seem to mine at a fairly constant rate.

I have the GPU's mining BTC because I am trying to squeeze out as much BTC as I can.     I probably should have them mining lightcoin and convert the LTC to BTC though.  Just haven't researched LTC enough to make the jump yet.

Hey I've been a lurker on these boards for a while.  I'd like to upgrade from lurker to participant if possible.  

Here is my mining rig currently 47 ASICminer USB sticks along with a 7970 and two 7850's producing about 17 Gh/s.  I started with buying from Newegg/Ebay and graduated to buying through group buy's.



Thoughts?
