Nice speed! any chance of measuring the power consumption?
thx!
thx!

Anyone OCed his Batch 7 to 650 Mhz ? is it performing well ??
Playing around with different clock freqs. Here's a snapshot from my current test.
Looking at the RPM's on those fans, you must have them set around 30% manual. It looks like you need to bring up the fans to at least 80% to get those HW errors and temps down.
Here's the perf with 687MHz clock speed.

One question guys. I Planing to buy Antminer S7 - batch8. I dont know why is this batch overclocked on 700m and hiting "only" 4.7Ths? Previous batchs hit this hashrate with only 600m-625m. Is this some bad batch or what, I suppose b8 unit will heat lot more than previous.
It's not overclocked if anything the other batches are underclocked relative to the Core Voltage. Reason it's 4.7THs is that like Batch 6 it has 135 v 162 Chips. However we have no feedback on exactly what the changes to the Chip Power supply or exact efficiency in Batches 6 & 8 yet?

Batch 9 better be $1,200/3.3BTC or less because we just hit 600,000Ths. We got a 10%+ diff jump coming in under 4 days. The next diff jump after that looks to be between 10%-20% at this rate. That will be in less than 20 days. Remember that this all compounds on the last diff jumps, so 10% now is equal to what a 15% raise would have been two months ago. It looks like we might be in for another hashrate armageddon.
That said, I just got my "sold out" batch 7 units in. If you look at the jump in the last 2-3 days I'm pretty sure its the fact that we all got the last few batches early this week and wasted no time getting them all online.
I think batch 8 might ship soon too so that will be nice for those who buy them. For the rest of us it will suck because it will mean another jump even sooner than expected. Avalon is shipping another batch right now too so...yeah...I'm a bit worried if both companies keep shipping like this. I think they will.
One funny thing is that they are ruining their own farms profitability. I guess it doesn't matter as much to the farms because they get their gear at cost (like $300 per S7 I bet for parts). Its just sad to see this race to the bottom. I was hoping to actually make some money on these, not just hope to break even.

They dont hurt themselves, they get to sell this stuff at 1800-1500 while people are trampling all over to get miners wherever they can because the BTC price nearly doubled.
By the time they ship those late batch, the diff could be 20-30% from now, if it is, they win even more. If the BTC price drop, they already made their money.
Mean while they have tons of money to roll more hardware and dev the next batch, assuming they dont already have S9-like stuff for themselves.
I guess they dont even need to do that, considering they get super cheap electricity.

we need batch 9 with full asics clocked at 650! 
I need S7+ with at least 300 chips clocked at 650 MHz and slightly better efficiency
Later edit : and at the current price of S7 B8, of course !

But:
Here is what the wall outlet looks like, right next to a window. There are 2 separate 20 amp fuses in the box next to eachother turned off. They are labeled "httr I flor 240" .... the previous owners were European that spoke very poor English
That looks more like a 110/120 outlet. 220/240 tend to be much bigger. Some one correct me if they think different. Here is a example of my 240 recpetical. http://www.lowes.com/pd_197494-334-L630R-L_0__?Ntt=l6-30r&UserSearch=l630r&productId=1056959&rpp=48
That's a NEMA 6-20p receptacle, 20amps 220/240 volts because it's double pole outlet (two hot 110/120 wires) installed with 20 amp double pole breakers with 12/2 line.

Then use this plug for your PSU to match the outlet http://www.amazon.com/gp/product/B0093WFT5C?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s01
20ampx220volt=4400watts x .8 (80%) = 3520 watts per receptacle
You can have 2 S7 with this recepticle http://www.amazon.com/gp/product/B000U3BVHI?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s02 and still have around 1000w leftover with 80% draw on the line.

Thanks!! I hope the electrician confirms this to be the case.

Phil I got you beat on the length of time as a seller. My EBay user ID is Playlikeachampion over 16 years. Sold a ton of Notre Dame football jerseys (why the name we have) when we started and then a lot of miners also. Cost got to be to high to keep doing it full time. You have me beat on the feedback as I am only in the 1300's.

I got my batch 7 online yesterday and the noise is horrible and I used to think S5 is noisy.
Fans run over 4000rpm and blades are about 50C, air is traveling too fast, screams and resonates badly.
3 x DPS-600 powers take 1400W from wall, I tested power draw upto 1600W.
Customs took 1BTC for sale tax but I have "free" electrics as garage is heated with S7 so I maybe ROI some day.

The wall outlet is labeled 20A 250V and I am in the US. I have an electrician coming by to check it out in the next day or so but I could not help but ask here first because there seems to be a lot of folks here with knowledge on this stuff
Do you have a voltmeter? If you so can find out if it's 120/240 very easily.
20A home circuits are not uncommon and are often 120v. 240v outlets look much different, as notlist3d linked.

You can watch some Youtube videos on how to install 220 to get an idea of what the electrician will be telling you.

Its one outlet that fit in the standard 2 small 120v, its not rated 40A+ like for the one for an oven. I'd be more worried about the power distribution and the wires behind the outlet.

I was curious about using a 240v? pdu for my antminer s7 but have zero experience with them. I believe my house has a line in it that I may be able to utilize but I need to have an electrician look it over first (2 20amp fuses with a funny looking outlet presumably for a window a/c unit?). I was curious what brand pdu everyone is using and what type of plug end it has?? Do these have built in surge protection? I currently use multiple corsair psu hooked up to some battery backups but no way to remotely reset them while I am away. Sorry, I am fairly new to this
Are you saying 2 20 together? Like the ones with the bar between them hooking them together. Or are you saying two separate breakers? (40 amp would be a TON to give a window AC I cannot imagine any window ac having this, that is why I want you to check). Does your fusebox have written inside what goes to what? If you had a good electrician it will.... if lazy one it will be blank.
But on PDU I owe it to phil. You can get them much cheaper on ebay they the stores. I was looking at amazon and such and used working PDU's show up a lot on Ebay.
But I think find out more about the fusebox and go from there. But if you feel uncomfortable with power get a electrician as there is a lot of power. So it all kinda depends on you.
Yea, for that I would assume a standard dryer hookup as those are usually 40 amps.
It's hard to tell being across the internet. I know I have a lot to my kitchen to. I'm hoping it is written on the inside of his box.
But so far I'm not sure if him looking at it is good. I don't like to tell people to go check in it unless they are confident. And electrician will give quote for free if you are wanting 240 and not conformable doing it. Some are much better then others at telling you what your current setup is.
Are you in europe? Or us?
