Re: [Guide] Dogie's Comprehensive ASICMiner Cube Setup

I've been having a weird issue where one of my cubes randomly shuts "off"
I say off in quotes because it's still getting some power, but only 1 of the 2 power lights will be on (the 2 vertically stacked, the top stays on) and the fan continues to blow, but it pushes cold air and the device doesn't hash or respond to web requests. I can then un-plug and re-plug one of the 2 plugs (doesn't matter which) and it magically whirs to life again, for some random amount of time.

I have 2 cubes (and 1 BFL miner, no oc, total power should be < 700w) running of a Corsair AX860i, and it's always the same cube having the issue so I don't think it's a power issue. The fuse looks fine and I don't see anything wrong looking at the board.

Anyone else have this problem?

Ok this is not the fuse, I also unplugged the working one, it still shuts off. I will try to replace the fan...

That's a lot on just one 860 W PSU. I have a 850 that won't power two cubes just on its own. Keep in mind that not all cubes have the same sensitivity to power. My first question would be that if it's the same cube always, does it still doe that if you put the other cube on its own PSU?

Don't the cubes pull 200w each? (These are NON-oc'd, OCing them, even with JUST the 2 on the PSU and they go all X's after about 30-60 minutes). So that's 400. And the BFL miner shouldn't be THAT much (the PSU previously ran 3 cubes, until surprise surprise the BFL PSU died) but who knows maybe my math is way wrong. So I have a new PSU coming in the next day or so but I'm not convinced this is a power delivery thing...but then maybe it is and my issues will all go away in a day when I get another PSU to hook things up to.

My Kill-A-Watt says something like 340 W for OC'd and I think I remember 260 W for non-OC'd - and besides not all 860W are on the 12V rails (sometimes it's only 75% of the total rating!), and the ratings are max, not constant-draw. But it's more than that, these things are persnickety - first thing after configuration settings and physically ensuring heatsinks and blades are properly installed, IMHO, should *always* be to ensure that the problems still replicate with no way for power to be part of the problem. Second thing is to do the same for network "cleanliness" (i.e. nothing on your subnet but the miner and its proxy). If the problems still persist, then it could certainly be something with your hardware or setup that you missed.
