Topic: Antminer V9 4TH - page 10. (Read 19995 times)

If it actually is a new 16nm chip, it could be the first test run trying to beat S7 efficiency and fell flat, so they re-engineered and came up with BM1387.  So they went ahead and finished out miners with them just in case, and put them in their own datacenters and ran the crap out of them and now they're selling 'em off.

Or they actually are S7s, and they put them in their own datacenters and ran the crap out of them and now they're selling 'em off.

The best stable settings I have run on an S7 are 3.3TH/700W at 0.205J/GH at the wall.

Yeah I am asking me the same, but for any reason the T9 was always a very quick sold out model.
I asked me the same: WHY?!
Even sometimes S9 were avaible.

Then a good friend of me showed me something during a visit at his place.
We are both inside Mining, but we know each other since years - before the first bitcoin

He has some of those T9 and he is undervolting them extrem!
He has just 6-7 TH/s - but that leads to a power consumption per Hash what is better then any S9 has.
But on the other hand it leads to a very very high investment each Hashrate.
He has a mix for "good days" and for "bad days" of S9 and T9.

I have the feeling that you maybe can undervolt the V9, too.

But I end with the same words like smutboy: Who would buy such a crap?!

Well, on the other hand I see the price right now. USD 345,- (plus PSU) / 4TH/s / ~1000W.
If you buy 5 you will have a power consumption of 5000W (5KW!) for 20 TH/s and payed a bit less then for S9, because one S9 = 1x PSU.
5x V9 = 5x PSU. It adds up.

If you can all undervolt them to 3 TH/s even while halfing the power consumption to 500W each, it will lead to 15TH/s and 2500W ---and I dont thing that undervolting will work like this example ---- garbage!

They say for long time running. Ok. Where is my 5 or 10 or lifetime gurantee included with free replacement?
Even my Zippo lighter has it  

Seriously who will buy such a crap?

Only some one who has free electric or someone who wants to spend more in electric per month then this can possibly mine per month. 

Cause at there efficiency rate combined with the difficulty rating these are IMPOSSIBLE to turn a profit on or any way they can even break even in there life times. 

Even the s9 is starting to get to towards the end of profitable mining unless someone has free or really cheap electric. and by the next 2 diff increases then even s9s will be makeing less btc per month then they use in electric every month.

Yup, these things pretty much kill whats left of the S3/S5/S7 Market at the price premiums they have been going for.

the MOQ of 5 is to limit orders/traffic to bitmain so that resellers will pick them up most likely.

If it was not for the MOQ of 5 and the shipping cost I would actually take them to resell to people.

Much like the S3 units and S5 units I can explain that yes, it's a hobby you are going to loose money at with this equipment at this price BUT it let people get into BTC mining without dropping $1K+ USD on a miner. If they wanted to keep going they could buy more and better equipment. If they didn't so what they dropped $400 or so.

Hell, if you ride motorcycles you can drop $650 on a good riding jacket in the spring that you "expand" out of over the winter.

My opinion is that BM1580 is just a rebrand name for the old ASIC chip BM1385, used in the S7 miner.

The sad part is I bet they manage to sell a few even with the 5 unit MOQ. Funny how all miners are now in stock/shipping or shipping at a later date with the drop in crypto prices. Shady Bitmain tactics as usual

There will always be clueless people to buy whatever Bitmain decides to sell, and we can't do nothing about it..

They just want to get rid of their old S7 units that are barely profitable anymore. There's still people that will probably buy them that either have near-free electricity or are clueless about mining.

If it is SHA256 then congratulations Bitmain for making something more shitter then a D3. Costs more in electricity lol

I got the emails this morning and saw the specs page (which doesnt list algo ANYWHERE!!) and thought this cant be a bitcoin miner...it must be for another algo. Well that was until they posted on twitter sayin it was a btc and bch miner. It would be one thing to sell miners that r dated to clear a warehouse out...im perfectly fine with that idea and support it. Its a completely different thing to tell customers that it has a new model chip in it when in reality its an old outdated model chip. Thats just plain lyin.

Yes other companies rebrand the old hardware to sell them on but other companies actually improve the design or boost the specs a bit (in the case of video cards) or they slap 2 chips on 1 board....in other words they make the purchase worth while 9/10. This however is misleading and outright fraud in my opinion and im shocked that anyone would think this was a good business model to follow. I have free electronicity and even i wouldnt touch these. Space is a premium...power is not. I try not to hate on bitmain TOO much but this is terrible. I feel bad for the guys that r gonna get punched in the dick by this company.

...still many will buy it

Yup i agree. they are lowering inventory and increasing sales. Making it easier to move out of china when the time comes.

Lol true, that's lazy. 

They have just put a new sticker on top of the old one.

well if you look at it closely, you can see the white sticker on top of the black/yellow one and it 's off!

I see it very possible, that Bitmain is moving a lot of operation to the USA and Switzerland.

Save the planet, destroy all V9 !
Seriously, are they selling old hardware before move to another country (china restrict) ?!

Well, it is not a new thing that manufacturer renames a old design with a new name.

We have seen this before with AMD and their Radeon GPU series.

It does not look like s7? I compared the photos. Unless Bitmain had a burden to replace control units of all their old S7s.

I know, I was just trying to be positive.... :-)
