Who's buying these so close to halving?
I picked one up, plan to get more. The halving doesn't scare me.

I ordered.
3 for BTC and
2 for USD (Total 3867.83 USD) Today
So I can use my 1300W PSUs.
Total
10x B1 + 1x2/3 S9
1 x B2
2 x B3
5 x B5

I am running mine at the downclock freq of 525 until it moves to the solar array
looks pretty good. my ac amps are pretty steady at 5.1 ac volts are 240 = 1224 watts my psu rates at 92.6% so 1224 x .926 = 1133 watts dc for 11285 gh or
just about .1004 watts per gh rate. at dc level vs .1084 watts per gh at ac level
i added a correction the hw rate is 0.0001%

S9 B4 - So far working as advertised. I am impressed. One of the few miners from Bitmain that hashes at it's advertised rate out of the box.

The S9 still isn't listed on their Chinese site. Apparently only "Westerners" are.

this temperature is ok for S9 batch 2 or I need to lower down the frequency or to set fans to manually ?

Those Temps are acceptable
Nice temps!
this temp is perfect or I need to do something to lower down it ?
Perfection for s-9 temps is not important. Good numbers are fine and your numbers are good. Don't worry be happy
thanks phil

I just made another order yesterday. You are either in or out in this business; even through the negative speculation. Many people are holding off is a sign to me to buy! The early chips like my S7s were/are my most stable configuration with overclocking capability and stable cooling. I do not overclock all of my miners, some are underclocked, but you have to find the sweet spot for each miner. There are those that speculate on the basis of the BTC staying the same....I say this is incorrect. I believe that there will be a dramatic increase over the next six months.
My 2 cents.

I wonder if they sorted their chips on this first chip run and are adjusting the miners to work with the chip run.
B1 had the best chips and they are working through the rest of the batch. Just a thought. Not my area of expertise.
My B4 has arrived and started up. No hard data yet though.

I wonder why the default freq on these is only 550. Same number of chips as previous batches, so no doubt the same board. Why lower the freq and thereby the hashrate? Are these QA failures on some level?
Yield and manufacturing variation on a very NEW manufacturing process node, I'd guess.
Batch 1 seemed to have some MAJOR issues with not being able to meet it's specs on a lot of units - similar to the early S7 batches, then they redesigned the hashboards on the S7 to use a buck and fewer chips running at higher voltage, thus managing to meet the hashrate spec while eating noticeably more power....

I got a B3. It was kind of a sweet spot because BTC was at a high point, and I got it with enough time on this side of the halving to be significant. I actually have a chance to ROI it in BTC terms.
But the other batches have not made sense. In fact I just ran the numbers on B5 and it's worse than B3.
These are going to have to come down in BTC price terms before I'll get any more of them. I expect that will happen soon after the halving.
Or maybe monkeys will fly out of my butt and someone will start to compete with Bitmain. That would help drive prices down.
Whatever happened to BW's miner, for example? They been mining with them and were supposed to offer them to the public last month.

Rumor has it you can flash the low frequency firmware update on all batches. Weird thing, it wasn't available via their website. You had to download it on bitmain talk.

Why does B1-B1 state +7% at the wall efficiency, but B5 state 1,172w + 12%? If true, then even at the lower hash rate it's less efficient?
no just a bigger fudge margin to still be in spec.
remember they are all we got so they can pretty much do as they please.
