I would recommend underclocking them. That way you'll avoid the fire risk, and they run a little more efficiently.

Do you happen to have some settings? I'm using 240v 30a and using the y-cables to run 2 pcie to each cube. Not sure how to read everything correctly, but temps are running < 60c and DC < 100c. I've got 6 going at the moment on one controller doing 4.1Th and showing 1731w. I'm guessing that's chip level? But even so, it should be very comparable with my underclocked SP20s.

3T at 1308 watts is very good

it is at chip level
when you measure it with killawatt it gets around 2kw (depending on psu eff rate)

bonus neptunes are crap, cut from wafers remains

bad dies, cold cubes etc.

It seems to me that you made a pretty good deal. Wink

Just because everybody hates KNC right now it doesn't mean you can't made some decent deals with their stuff. Grin

Where did you get that deal?

Off Ebay. Bought 3, figured I can make at least 2 good ones if they don't all work up to spec. So far just still playing with the first one. I've had to flash the firmware once so far.

Ok, I was able to pick up a couple of the 'new' bonus Neptunes for less than $.22/gh. Besides being fire starters, 'scam' company, etc, what's the problem with these that I was able to get them so cheap?

There are not the most loved unit. But for .22 cents I personally think you got a good deal.

Status so far:

Received today.

Have set up one set of 5 cubes. I forgot how finicky KnC chips are. I've got 2 cubes with a couple dies that cycle, but so far running around 3T at 1308w. I'm figuring there must be a bust in their firmware because that seems way too low.

2 more to set up tomorrow.

They basically don't work right out of the box. If they do they have bad dies and bad VRMS.

Well at least I'll know what to look for right off the bat. I figure if they don't work, I'll file a dispute and get my money back or a credit for the bad dies. Paypal and Mastercard are pretty good about that.

Also, I have a bunch of Corsair CX500 laying around. Can I attach one to each cube using the Y cable so as not to overload the PSUs?
