Topic: Varispin Solar starting advertising of a new miner.... 48TH-3000W (Read 304 times)

I never got a response when emailing their "info@" address.   Miner friend of mine called and spoke to Mr Scott, and we've communicated previously via this email address.......   [email protected]

I've probably exchanged 4-5 emails with Rob. I am under the belief that he's back n forth to China often as part of his job.

Here's a copy n paste of one of his responses to me when I inquired about the Starlight unit, after they had to cancel their S17 pro orders:

I have gotten no responses to my inquiries on being able to visit their location for local pickup.

I purchased a Bitfily A1+ from Varispin through Amazon.  It amazingly arrived about a week before it was projected.  However, UPS totally destroyed that thing.  All the rivets were blown out of it, RJ45 connection was smashed, 2 fans were stripped out from the drop and all the fan guards had to be pried back away from the fan blades.  The case itself was even warped from the lack of structure.  Everything appeared new inside the unit though, as advertised.  There wasnt a speck of dust on anything. I was able to stitch everything back together and install the boards...only to find out that the SD card in the OrangePi Zero was blank.  I couldn't get the unit to draw an IP so I'm in the process of returning it since Varispin has stopped answering emails and phone calls.

Anyone else had any dealings with this retailer??

my take on the coating is that if it reduces radiant heat, is that it can reduce possible cost on cooling - but yes the air would have to carry more heat so maybe they are using higher cfm fans? would that affect the efficiency to a significant amount?

that said, I am still willing to pay them a visit, if they will allow it.

Your contact still did not answer whose chips are used. Their own design? Ones bought from BitFury or Inno or (shudder) ebang or others?
The website says they use Samsung 10nm chips. For a start, Bitmain uses TSMC as their foundry - not Samsung. Either way, is irrelevant as the chip design itself - not the foundry - is what matters. Chip design is not part of what a foundry does, it is up to the customer to provide the chip layouts. Now yessss , foundries primarily only produce wafers full of bare chips that then need to be singulated and packaged into usable chips. If per-chip binning (performance testing) is done the packaging house would be the best place to do it. . If your contact is referring to using the same packaging house that BM uses -- I'll buy that but the chips are still Samsung.

The site mentions "assembly in same Tier-1 facility" as Bitmain uses. Sort of irrelevant, yes the plant is used to dealing with making power-dense and thermal-dense hash boards but once again it is the customer that provides the designs used.

Then there is that thermal coating... Sure, looks nice and also probably dampens sound a bit as well but - radiated heat is a stupid thing to address as that is a tiny fraction of the total heat load produced by a miner because the vast majority of the heat is carried away by the airflow through the miner. Insulate the casing and that just means the air has to carry more of the heat.

I am interested to see if they will let me pay a visit. and I sent you a pm

Yes, US office in Miami.
I've emailed the rep a few times. Shipment expected mid-sept.

And they're supposedly a real company, so I was able to purchase on a credit card.....  so, easy resolution if they are not legit

after seeing OP post this in another thread, I did a forum search and found this thread - you say these guys are in Miami? I am semi-local to that location. Hope they are legit - if you have not dropped coin on a miner from them already - see if they are willing to have someone local pay a visit to check out the miner - I might be willing to take the trip.

it is not as efficient, that part is correct but if it truly has a way to produce less radiant heat, it could save $ in other ways to offset the decrease in efficiency.

I talked to the varispin guy by calling the contact number listed on the website. He claims the chips are coming from the same factory that makes bitmain chips.
Not sure how legit this company is. Has anyone received their miner orders from these guys yet?

A good question to ask the rep is whose chips they're using for the build. Unless they started with around $100M to blow on R&D, they're buying from someone else.

(or they're lying and it's fake, but y'all already knew that)

Good point.  
Also wondering why no one's heard of this unit anywhere else.  The only place I see it is on their website.  And that was after they they listed S17 Pro's on Amazon for $2700, and are now telling people they cant get the shipment.

power supply can pull 3600 watts  the plug is an iec 320 c13 style it rates to about 12amps or 12 x 230 volts = 2760


the plug should have been a c19 it is therefore a possible fire hazard

Anyone hear about these yet?

Certainly not as efficient as others, but the price point seems a little more feasible than the $5k S17's

Varispin is a solar company, based in China with a US office in Miami. One of the guys in my stock trading discord room has spoken to a Miami rep, and should be getting one of these units late this month. I'll update as I hear more from him.
