6 Cube Neptune - 3.8-4.5Th on CKpool Looking for a Price Check.

[bgibso01]

I've got a 6 cube setup that I have had running since last spring.  I've got them all tweaked to not run too hot on the DC side so not getting full output.  All dies are working and a 6 port controller.
I have not been keeping up like I have in the past so not sure where the market is now.  Looking at the postings here, it seems its all over the place for $/gh and not really a good correlation to the w/gh.

Thanks.

With recent difficulty increases and gear available I probably wouldn't pay more than $300 or so, personally.  Others might pay more.

These are still holding great value because they are very efficient, they are generally priced 75% of what an S5 goes for in terms of hashrate so you can probably get around $1000 USD for these if they are working perfectly.

The Jan20 S7 batch is priced around $1000+shipping, IIRC.  That's more than twice as efficient and 30% or so more hashrate.  Not sure why anyone would pay anywhere near that for these.

Yep see what I mean.  I can't see a reasonable way anything is priced right now.

This is a weird request, but can you sell me just one cube? I have a 4 cube Neptune that is missing their 5'th brother.

I agree with you but nobody is selling any 0.5W/GHS hardware at decent prices these days so everything is overpriced. People are paying the same for an S5 as an S7.

id prolly take a pair of cubes or maybe even 3 myself if they are priced good

I'd take 2 or 3 fully working cubes. Could probably work out combined shipping with allinvain if he's interested since we're both in the Montreal area. (I think?)

there ya go between the 3 of us we could buy up all the cubes

[adaseb]

See there is huge demand for this type of hardware that's why the prices are still very high. Same with S5's.

That would be perfect. Yes, I am also in the Montreal area.

Why not just buy S7s?  If people want to pay the same $$ for half the efficiency, I guess that's their business...

EDIT: The Neptunes are quieter, I suppose.  That's really the only advantage that I can think of.

I don't think anyone will pay as much per gh as an S7, obviously. 1000$ for a Neptune is silly, unless you're adaseb, but I don't think he's buying. 

[adaseb]

The only reason I can think of is either the noise OR that people rather invest $250 on a S5 rather then 4 times a much, maybe they dont want to take that risk.

$250 is not so much money but $1000 is considered alot. I mean thats most peoples mortgage payment pretty much.

What's the REAL WORLD power usage measured with a kwmeter?

Great! So, bgibso01, you can consider 4 cubes as sold between allinvain and I, and seems like the remaining 2 cubes are spoken for as well. Are you willing to split the miner up between us? I'd probably like the controller as well as the 3 cubes to have a backup and a testing platform for determining lowest possible voltages.

What's the REAL WORLD power usage measured with a kwmeter?

384W DC per cube running all dies at 500MHz. Depending on PSU efficiency, ~440w per cube at the wall.

That's roughly what I used to see on mine as well.  I found it best to run at 450-475 and undervolt a decent amount, try to get each cube down to around 325-350W or so.

Definitely not a bad idea considering how overloaded that poor little 6 pin connector is, even at 325-350w. Fucking KNC... These things would've so much better with a second connector.

Yeah, I was using my 16G cables and 1100W server supplies and I still didn't want to run at full tilt, and not just for power conservation reasons.  I trust those, but many PCIe connections just can't reliably push that kind of power over the long term...
