(Review/Guide) Hotmine X5 upgrade kit for Antminer S1/S3/S5

[HagssFIN]

The warzone in Ukraine is far more in east than where Kiev is located.

I think Hotmine is located in Kiev, since that is where my shipment was sent from.

[mamontkiev]

Hi guys.

We based in Kiev and it is very far from war zone.

We will be really happy if somebody from Europe or even from USA will come to our place and will see our R&D facility with miners and other equipment. By the way, Kiev is very beautiful city

Next week we will get few dozens free (not prebooked) X6 upgrade kits and will contact with all who wrote us in PM or here.

Additionally I will be in NYC from 16th till 25th of May attending Consensus 2017. If you don`t want to buy with advance payment, I can take 10 upgrade kits with me, meet in person and sell you in NYC. You can choose somebody from the city to be escrow/intermediary and send BTC to him if you from other parts of US.

Please let me know if this acceptable for you and you want buy X6 upgrade kit in NYC. The price - $1000 for one pcs (1,15 kW, 7,5 Th/s).

Hi guys.
The price - $1000 for one pcs (1,15 kW, 7,5 Th/s).

These numbers are fair, it's good. I was not able to get higher than 8 Th with my (S)X6 at 13.4 V.

I wonder if there's anything that would fit a Gridseed G-Blade.  Boards are 276mm x 90mm x20mm.  The price and the wattage both seem kind of high, I was looking for something more like 50 watts per board (less chips).  The G-Blade's getting old too, and there were a lot made I think.  It earns about $0.20/day now.  Jumping from Scrypt to SHA256 would be OK I guess.

Some pictures of a single original board at https://www.aliexpress.com/store/product/Gridseed-5-2-6MH-G-blade-USB-miner-Scrypt-Miner-dogecoin-litecoin-mining-machine-Gridseed-Blade/1490096_32446230074.html

Nope. Only upgrade kits I have seen are Hotmine upgrade kits (X5 and X6) and then there is sidehack's retrofit project with Bitfury 16nm chips (in development). These two both are compatible with Antminer S1/S3/S5.

[sidehack]

Before I have upgrade boards I'll have a ~70W pod miner with BF16 chips.

[ab1jx]

Right, I haven't seen pictures of the insides of the Antminers but they seem about the same.  Two boards mounted to heatsinks with a fan at the end blowing through them.  The Gridseed boards are more self-contained: there's no controller board, each board has power and USB connections and can function independently.  Gridseed put the heat sinks on the outside, Bitmain on the inside.

There's somebody selling S5 boards for $56 delivered at https://www.aliexpress.com/store/product/antminer-S5-557Gh-s-miner-Fitting-30-chip-pcs-PCB-28-NM-Calculation-circuit-board-bitcoin/628736_32686804147.html?spm=2114.12010612.0.0.u2K6fU but I guess you also need a controller board.  Otherwise it's not much more than a Gekko 2pac for 15(?) BM1384s.

Apparently Gridseed only made the 5-chip and 80-chip then retired or something.  Strange industry.

That's what I'm waiting for, if I can afford one.  And I'll keep my Gridseed earning $4/month.

X5 upgrade is still in my wish list but summer almost here and I can't manage more heat for next 3 months.

I'll be reselling these in the USA I'm in the Seattle area if anyone wants to check them out.

Working on building the first X6 right now, I got 5 kits from Alex last week.

Give me a few hours hopefully I'll have it up and hashing.

[toptek]

if you need escrow services let me know.

[numnutz2009]

i have 4-5 antminer s5 kits minus the boards from when i put them in a water cooling setup if people r interested in controllers heatsinks and all that other stuff. shoot me a pm and we can work somethin out.

[Eagleone]

2 built 3 to go, I'm going to have them at CFlocations if anyone knows him.

FYI I like Philipma for escrow only because he is active on the threads I read (+he is an internet community service superstar)

I'm being told months until I can get more boards... so no one flip out.

also I think the original S3 is best for the upgrade. you will need a beagle off eBay, but The heat sink is alot nicer.

That will go for sidehacks boards as well

We/I will of course buy ALL the boards/products sidehack comes out with in as large a quantity as can be afforded because he is stateside.

I believe I have an interesting and new group of people to sell miners too that are not being reached by any of the resellers on this forum.

I'm always going to distribute things I use myself.

Thanks all for your positivity and support

You can see one of the X6's at the bottom of the list

Pictures to come
+ I'll probably need my own thread for this

[achtung082]

Why do you say the S3's are better?

[sidehack]

Why not say the S3s are better? S3 is probably the most well-thought-out miner yet built by any company. Simple, reliable, solid, quiet. Everything everything these days is not.

Also, I've still got a whole stack of S5 beaglebones right now and will probably have a whole stack more for anyone who gets one of these kits.

[achtung082]

Why do you say the S3's are better?

I meant why are they better as a donna for the parts. Is it price to buy or are the heatsinks better? I always thought the S1 - S5 hard parts were all the same.

[Eagleone]

The S3 has a completely different grade of aluminum machining. Maybe meaningless in the long run but the fins are going to be a tad bid quieter.

I should mention these puppies take 4amp fans on both sides if you want to run them wide open. Ive moved it into my house for the evening and turned it down aggressively so it's hashing around 5.5 with antminer fans turned to 30%

Sorry for being a n00b but how do I put nice high res pictures on here ?

[HagssFIN]

Crap. The miner is still going on strong but the original fan of the power supply failed  
Fan-wise I don't recommend Enermax Revolution 87+ 1000W PSU for anyone.
This is already third case in which I have to replace the original fan with a new one (I have a total amount of three of these power supplies).
