got down to 200 on coinbase  back up to 230

my guess is bitmaintech converted all of its s-5+ sales to hard cash.

They had more the 200,000 usd in s-5+ sales
cashing out fast like that? Or this?

Looks like batch one of the S5+ might be officially sold out, i know day one it was greyed out but it came back up a couple hours later.

Also looks like the used S5 batch might be sold out, it has been greyed out since early this morning.

 They tend to grey out stuff while they're adjusting their posted "bitcoin price =".

After they launched New chip BM1385 Chip ( 230W / T) , I think people prefer to wait for the S7 that based on this new chip .

One technical question I have:

- What i know/heard is that when you have one dead chip in S5 device the whole blade will stop working, where this is not the same on S3 devices.

Is this true and does it mean that because of bad cooling (let's image) you kill one chip from the blade the whole blade would stop working and you have 1/2 of S5?

Please someone confirm this.

Best regards,

The first post is ITOP selling the machine so I think this is the right place. Bitmain have their own official thread for discussions of their machine.

6 overclocked s-5's = 6 x 1300 that's 7800gh  at 600 watts each you are doing  3600 watts

this does 7700gh at 3400 watts    a savings of 200 watts



No. Even at 220V  6 overclocked s-5's  need more, as 3600 watts, if you use bitmain PSU-s.

yeah I thought I corrected that.


at 1300 1 s-5 does 676 watts x 6 = 4056

I have it correct here
https://bitcointalk.org/index.php?topic=1146965.msg12085674#msg12085674

I went back and fixed it here

https://bitcointalk.org/index.php?topic=1146965.msg12085484#msg12085484


so this big new s-5+ is 7700gh at 3400watts   and 6 over-clocked s-5's are 4056 watts

you power savings is 656 watts about 48 usd a month (at 10 cents a kwatt).

price is 700 usd more  which takes 14 months  at 10 cents a kwatt.

Basically it is just plain over priced.   

 If it cost 2675 shipped  instead of 3378 shipped   you could argue it was better. Since you are paying the same and saving 50 a month in power.

The problem of it costing more then 2500 would still exist. You get import duty issues over 2500.

 




It just blows my mind how little people on this forum understand supply and demand. Yes bitmain is selling them for a lower price. Sorry bitmain doesn't have any for you to buy. So no you are not buying anything from bitmain at a lower price. They have been out of stock since the listing was made... So their price is pretty irrelevant now isn't it?

Both are still greyed out and states sold out.

I agree I get people sending me offers for less then what bitmain sold them for and there sold out I am like hmm how do you come up with that number if I have it and no one else does then obviously the price on the website is irrelevant because I have one to sell in hand and he doesn't right? or they say something better is coming so I say go ahead and wait and see how long that will be

I was having a bit of trouble finding a pin-out for the 2880 server PSU jumper switch and AC pug wiring. Anyone?
