i also watch bitaffnet pool for real time net hash rate.

well whoever it was.. just turned off 30 peta lmao

The reported hashrate is an estimate and is not always accurate.

This is because of how most tracking sites estimate the hashrate; a run of blocks will cause it to appear there has been a large increase in hashrate.

I think we will see big bumps soon; but I don't think the Network hash rate is currently 470-500 peta. Maybe 450.

Not sure about your and my idea of 'quietness' is, but even with fan changes and downclocking to sub 1TH, my S5's were still too loud and annoying to use in my office or anywhere near people. LOL.

Hopefully these new chips run cooler so they don't need a jet engine to fracking cool them off.
My SP20's at the same speeds were 1/2 as loud as my S5's..

I think I found a way to cut sound a lot. I will post in detail when my s-7 arrives

But seeing your elect up to $0.15 per kwh, how long S5 give you ROI from pure mining (not selling the miner) ?

I'm not sure my S5s are going to RoI - too many factors I didn't forcee ahead of time, I'm seriously regretting buying the 2 "used" ones from Bitmain in particular.

The 14.2 is only my "summer" rate, that ends in a few days and I drop to around 6.7 which gives me a prayer - especially if Bitcoin keeps climbing slowly.

I've given up on even thinking about S7s though, unless the price on them drops a LOT very soon or difficulty suddenly goes flat soon. I've still got over a month before I COULD have had the cash to even think about ordering ONE though, since they made them BIG miners instead of HOME miners. 8-(

Around what location are you at? That is a heck of a drop fro 14.2 to 6.7.

One is almost impossible to roi other is doable most likely.

Keep your chin up and you can make it happen. I started with a cheap video card slowly (slowly) mining LTC back in the day, then eventually scratched everything together to buy a ... 1.5 Ghz BTC miner (maybe it was 5 or 10, I forget) and worked my way up from there. Re-invest everything you have and exercise patience and you'll make it!

It already is. You can buy it now for ~8 BTC to be deployed October 10.

SP20s tolerate heat a bit better than S5s, in my experience with a limited data set, but mostly 'cause they are a TON more configurable.
They're quieter, but not a LOT quieter if you are pushing them anywhere near their full hashrate.
They ARE a lot quieter if you undervolt them some, can still get 1.3-1.4 GH with a fairly low noise level and close to S5 efficiency in a cool room.

My "summer" rate here (mid-June to mid-Sep) exceeds 15 cents/KWH during the day easily, due to ToD rate adjustment, the OVERALL is about 14.2 but that's only WITH ToD overall adjustment, without ToD it WOULD be a hair over 15 I believe - this is in Iowa with Alliant's ripoff "tons of extra fees" rate BS. Our rates where I live have gone UP at least 3 cents/KWH in the last 5 years due to Alliant adding way too many surcharges with almost NO reduction in the base rate to compensate.
The rest of the year isn't so bad for those that use a lotta electric - first 1200ish KWH are sorta pricy, but after that it's around 6.7 cents/KWH for the "anything over" third residential tier.

I still have 2 S7 coupons available at 0.1 Bitcoin each. I don't live on this board, so don't expect "instant" response to mails, but I WILL get back to you.

Thanks man, thats help me alot.

Actually, I received a replacement hash board for my S5 recently which has the many-small heat sinks, one attached to each asic chip, and it works great, and runs a LOT cooler than the old-style cooling system, where all the chips on the board have thermal paste on top of them, and they are all in contact with one large heat sink.

So I'm sure the S7 (and S5+) need far less fan power to keep them cool, which is why they can be packaged so much more densely.

You do not have the right twice.
1. many-small heat sinks are attached not to S5 chip . And You still need the large heat sink and thermal paste for cooling chip side of hashboard.

2. S5+ need more fan power to keep them cool as S5. Almost two times more. The same tornado also be S7.

I have to disappoint you all, S7 is full of chips and cooling elements in ,what is a lethal combination.

It is hot air tornado!!. Much worst than S5.
Unfortunately inside S7 is so overcrowded with chip and cooling elements ..the method with other quieter fan does not help.

I remind mistake for one destroyed and burned part of my FEW S5!!!. fell internet or pool and miner was ordered from does not count and so reduce the fan speed to a minimum.
But the driver software what had Stop of counting in the chips, NOOT stopped counting in the chips and they counted on, so one part of S5 is the burnt... Lips sealed

i have pictures in S5 thread
That error but affected thousands of people. bitmain still did not give a new firmware for s5 and i cant flash my s5 for some error

So you GIVE great care to ensure that such same error does not affect your expensive S7 $ 2,000.

it's not a teaser, just 6 mo contract...after 6 mo you get a different contract..this is how it works here, although i usually get a 12 mo contract.

I would like to try SP but already sent my fortune to bitmain. SP20 half loud of S5, but how about its heat ? If its cooler I think I can put it on my office..

R u in USA ? How much elect prices you get ?
I got this :
http://www.eia.gov/electricity/monthly/epm_table_grapher.cfm?t=epmt_5_6_a

Yup, in the Northeast, I pay $0.148 per KwH, but my colo is at $0.10KwH and I have free power available also at a few places if it's not annoyingly loud.

Sad part is, 50% of the price of electricity is all BS fees and taxes. UGH

Free elec, thats looks nice. Did you try to underclock too so less heat and less loud ? I "use" friends in dorm to put some of my S5s (since its elect-free), and I give them half of elect prices, so I give them $20 for every S5 put in there. With this they wont complain of the noises Cheesy

I can't imagine them doing this. I did not mine in dorms or student housing. Just was not worth it to me. You have limited electricity so can't put in enough to make a lot and then you have a noise when your doing homework or have people over. Just not worth it.

I was always lucky though and had another to mine though.

Because in my country a $20 worth 20 times meals with rice chicken and ice tea. And for 5x S5s basically means a person can eat for a month, 3 times a day. For students in colleges who still supported by their family, they really love antminer. Thats how bitcoin changing "our" world Grin

wait hold up - are you in the northeast usa, or siberia russia?
