Pretty sure those weren't DPS1200FBA PSUs. I'll check the model number just to be sure.

The 1200FBAs I've messed with had an internal adjustment pot and could go from about 11.8 to 12.8 (no-load voltage).

Got a new 28-90GH stick miner!

Also, 1050W wall means about 950W board-level. That's a heck of a lot of juice to push through an S5 chassis. What's board temperatures look like?

I have just upgraded the FW, so uptime is short enough, but here it is:



Numbers are the same when I measure the temps with an IR thermometer. It's a values received with a thermistor placed in the middle of the PCB. IR thermometer shows that those chips placed closer to the fan are cooler than the chips at the opposite side of the PCB. Sure it's better to add a second fan, especially if you want to put this miner through the wringer.  Wink

Maybe it is a shipping issue as I am USA and Rabinovitch is Russia

I suspect that there is just no any "second" unit yet...  Sad

Can we have some pictures of the unit?

What is your impression so far?

Sure you gyus can. It's all about time. There's too much snow here in Novosibirsk, so yesterday I've spent too much time cleaning my courtyard, moving cubic meters of snow from one end to another... Undecided

As I mentioned before the miner arrived to me in custom case in which the 51ASIC company demonstrated it at the Blockchain & Bitcoin Conference in Moscow.



There's simply a modified Antminer S5, an ATX PSU and a little display inside:



The noise level looks lower than in case of native S5 (if we can consider an Android-based sound meter precise enough):



Here we can see this miner hashing at 6.1 Th (12 V input) and consuming



When I connected the self-modified server PSU (12.7 V)



it was able to hashing at 7.5 Th:



consuming



At 13 V there's more than 7.8 Th (seems that it's because of older FW; now it's up to 7.9 Th):



You can see the multimeter showing 12.69 V at the 6pin PCIE power connector.

Sure I have a web UI screenshots, but it's time to go for me.  Wink Later I will try to create a separated "freestyle review" thread with all that stuff.  Smiley

so about 0.13W/Gh... far from S9's efficiency

Let's hope that these upgrade kits will be cheaper that S9 ($/Th) and more reliable. And in case of these miners/kits there is one important ideological point: a Cgminer is being used instead of some prorpietary "Bmminer"...

In addition there is no any separated heatsinks that can unstick and short circuit something... And the shipping cost (for upgrade kits) should be much lower since there is no need to ship the case, the heatsinks and so on.

The sales will apparently start next week.

p.s. be sure that you have read a fresh and juicy X6 miner/upgrade kit review here!

~0.117 w/Gh at nominal 12V voltage and 6.1TH, which isn't far off from 0.108 of Bitmain's, and that is their published specs which are often generous.

So just to confirm, the stock S5 fan and heat sinks is enough to dissipate the ~900W of heat board side? Seems unlikely given the S5 wasn't exactly over-built for heat dissipation, is it possible the unit you have has an aftermarket fan?

 The fan is the same as on the S7 - which DID have a one-fan model at even higher dissipation, though the HS were completely different.

 Not *THE* highest flow Delta model made - but 80% or so of the rated airflow of that highest model.


 The 2-fan S7 and S9 don't actually flow all that much more air - the only effect the second fan has is to reduce the backpressure, which helps airflow SOME but nowhere near doubles it.
 The HS on the S5 didn't generate nearly as much backpressure, so the second fan wouldn't be helpfull to any significant degree.

The difference is 4-5 C actually... Right now I am running X6 miner (S5 with new hashing boards) with two fans at 13.4 V.

Here's me bringing up an old thread but wanted to know if you still have the X6. If you do care to give me some output: Stable? overheating? problems?
I got 2 old S5 that i am thinking of upgrading to these X6.

Thanks

Unfortunately Hotmine does't want to sell the PCBs itself, only assembled miners. Not sure why.

The miner looks stable enough, I can only remember a couple of hangings when only complete poweroff could bring the miner back to work. It could be a PSU issue or may be my FW version is not most fresh.
The boards temp is always below or equal 60oC, in 25-27oC environment. If the summer wil be hot, I'll replace the mediocre thermal grease used by Hotmine with something MX-4-like.

I have ordered another 3 miners.  Wink

I bet you most had issues that they couldn't solve.. so they don't want to deal with novices.

Well i just went and double checked their site. At 1250-1350 usd for a 6.4-8.6th/s miner is more expensive than bitmain gear (AKA bought 4 antminer s9 12.5th/s at 1356 usd. Out of the 4 miners i got 1 miner that has a sick board. so that's a pretty low fail rate but i didn't buy as much as the next guy so maybe i got lucky. But hotmine is charging quite a bit for their gear.

Thanks

They're a smaller seller so clearly they can't compete with a company like Bitmain or even Avalon, both of which probably obtain and manufacture miners cheaper. It's just natural but I also agree it's a tad bit high. It's unfair to do direct comparisons for the little guys.

Bitmain has far bigger mass production of miners that Hotmine does..

Taking all into account, I think Hotmine's pricing is ok.

And remember, reliability is one costly problem with Bitmain hardware.
