Title: Selling Bitmain S4+
Post by: mrkubanftw on August 03, 2015, 09:27:40 PM
Hey guys. Here today to offer up a lightly used S4+ (shy over a month). If your'e trying to get a hold of one but can't, here is your shot.

A little back-round on my particular unit... as i hear its "special" (I only say this as iv'e not seen anyone acquire this hash-rate with this chip speed)


-It is currently averaging a hash-rate of 2,725Gh/s with an average temp of 75C. This is being achieved at a chip speed of just 212.5! Voltage is locked on S4+ so that has never been played with. Temps never rise into the 80's and that's with this unit in an enclosure that's around 90-100F ambient. I haven't had any issues with this unit shutting down nor any asics going down. The longest up-time iv'e had is around 10 days or so, this is due to the unit using my electric dryer circuit and me needing to power down to dry my clothes :P  -Otherwise i have no doubt this unit would run endlessly just as my S5 did in the same conditions. I will say in open air with ambient around 75F the unit tends to run at or under 60c so i hit the silicon lottery with this one.

*edit*

Forgot to mention my hardware errors average 0.0002% at the above mentioned hash-rate/chip-speed. It's also interesting to note that at stock chip speed and a lower temp the hardware errors averaged 0.0008%.

*edit*

Asking $1,300 shipped. Some may object to my asking price. To the uninitiated, hop on ebay and see what they go for now as they are disappearing from the internet. There is only one and it's listed for $1,900.

*Ebay $1,900

*myBTCpool $1,300 (No stock)

Another site I can't mention the name of is also asking $1,400 and is maintaining inventory of at least one.




Shipping from Wisconsin to anywhere in the united states. Willing to use escrow of course (OgNasty). Prefer cash or paypal deal, willing to do btc as a last resort.

Normally I wouldn't be an asshole like this but since you tossed out these market comparisons let's look at reality.. Anyone can ask whatever they want on eBay, doesn't mean it is the market price..

Last S4+ sold on eBay went for $739, that would be an more accurate comparison.

You are correct but i didn't JUST cite ebay. I cited anyone i could find selling one. You need to consider i'm not pricing this unit for what it sold for yesterday its priced for what its going to sell for over the next two months while Bitmain is cycling their new s7's into their farm and s5's out. It's high yes, insane even, and that's what its going to take for me to let this unit go. It is what it is.

Hey I'm not sure if you're trolling, but why are you bumping this thread so soon? It was still on the first page.
I'm sure you're going to find zero interest here, please don't spam.

A quick look below finds doge94 selling one for $750.  Not being mean but $1300 is insane.

Doge94 is selling an S4 not an S4+ which tends to differ in the profitability. I can find S4's all day and yes for that price. Find me an S4+ right now for under $1000. Don't worry i'll wait.

Within the united states shipping is around $60 due to the weight of this beast. I'd be looking for around 3.8BTC with shipping within the US.
