Antminer V9 4TH

[Kenni88]

A walk around the v9.  Smaller and lighter than s9.  Also is brand new.

How's the noise levels (decibels, perhaps a phone meter for some estimation) and temps of the V9? Noticed they're using the new Nidec fans, I've heard both positive and negatives about those on the S9s. I wonder how good (or bad) they are on the V9s.

During my brief test it sounded about the same as other contemporary antminers. Can't really measure though due to overall noise in my "farm".

Are u sure it is brand new? Why would they produce V9 over S9?

I can confirm they seem completely new to me as well. No evidence of dust or signs of wear.

I bought 2, only bought them because i have Solar the one i got to day seems new, looks new, has been running for about 8 hours with no HW errors yet, at a good steady stable 4 th ... may overclock it some later on .

temps B1 5o c B2 47c B3 53c

haven't measured the power usage, probable won't . to me the only set back that makes it useless is the power it uses, I 'm mining BCH with a A6 .. for the hell of it .

in fact i bought my two from CryptoCrane on amazon , wonder if the guy here is the same one ?. no big deal if  not i don't really care ... i had to ask out of wonder.

I'm measuring 950 watts from the wall when using an APW3++ on 220v power.

[toptek]

Ive got it on 110 line right now with 2 1200 watts hp 80 % psu running at 900 watts each,their to loud to keep in the room, I keep my GPU's and A6 were the 220 line is, Monday 19 th I'm having another 220 line put in that room ...which is sound proofed, later this month, i have a L3 plus coming and have a A4, i may sell it's being fixed, i hope .

The sad part is they refreshed some S7. the chips used are the same chips as the S7 chips like everyone is saying but i knew that when i bought 2, i just wanted two new toys mostly. they were cheap, i have solar power, so why not ..

I got one hash board down already out of 10 new units so far. We'll see how the warranty process with Bitmain is.

I have a control board on order 

[mikespax]

Do you just email support to start a warranty repair or is there a special link?

hey man what happen when your controller went up  ?. i think i have a bad one .

thanks for the PM back . posting here for others that may have bought this junk ..

Don't set it to a Static IP : you may have to get a new controller til they fix the firmware, if that's what it is .

Setting it static does something and messes it up ...an you can't access it any more, Leave it at dhcp, i guess till bitmain posts a firmware fix, if that's it.

It sells much better than if they would sold those as S7 miners like they are.

Well, by releasing the V9 Bitmain gets the opportunity to sell old BM1385 chips in 'new' form, so that's one reason why it's selling like it is now. If they had sold S7s as used I guarantee there'd have been less buyers.

If you'd read a few pages back you'll find the V9 design overall is slightly different than that of the S7, like the hashboard with L3 markings and outer casing. They're not exactly the same, but they are closely related with most specs. Given this, there would've been implications selling these as plain S7s, and most people want a more efficient miner nowadays anyways, as mining profitability on the S7s is dropping like a rock.

We're seeing a TON of demand for the V9 series from customers in Venezuela. Seems like 2/3 of our bulk orders are going to freight forwarding companies in Miami. Plenty of folks from countries with subsidized electricity rates are happy to have these little guys.

Side note, we can confirm that setting a static IP address will brick the controller. We've had to replace 3 units thus far from customers who found this out the hard way.

[HagssFIN]

Wow, that's bad engineering if setting a static IP address can actually brick the machine.

Looks like a new firmware was released on March 12th. We're testing it now to see if it fixes the problem. We're planning to communicate with all existing customers soon and it would be nice to have a fix in-hand.

Update: We've tested a couple units running the stock firmware from February 26th and could not reproduce the issue. All V9s successfully accepted static IP addresses and were still accessible after a reboot. We also tested the new March 12th firmware and found the same thing. We have a couple of V9s being returned to us right now that supposedly have the issue, so we'll update when we get our hands on them to troubleshoot.

Great news.

Is there anyway in updating the firmware when there is no access into the miner interface??
Could there be a way via using an SD card?
