So came home after work today to see that the power meter was only reading 404w at the wall. When I left this morning it was reading 590w (s7-ln and a raspi running two gekkos at 225m on the same plug socket).

One temp reading was 38 and the other 60. Ive rebooted it and will see what happens. Just wondered if anyone else has had a similar experience?

I had an S7 F1 board doing the same thing ... went down. Rebooted and it was hashing again.

Mine was still hashing fine. Registering on pools and GUI said the correct hashrate. Just went a bit funny. Rebooted and all is fine again using 590w in total.

Damn! My Super Flower Golden Green 500W PSU just broke today  Undecided
The S7-LN is fine though, I tried running it with another PSU just fine  Cool
Some idle time now though before I can get it running 24/7 again with a new PSU.

Think I got my calculations wrong before. Its pulling approximately 465w at the wall at 450M. After factoring in the efficiency of the EVGA 850 P2 is using 437w. Very nice indeed Smiley

do you still sell these?


also, how long would it take for you to send me the unit?


Thanks

I spent the last couple days writing some new PIC firmware for my S7LN (delivered Wednesday 8th) and have been testing it. Right now my machine is running 2.03TH and pulling about 415W off 120V, putting it at an efficiency of right around 0.205J/GH for the machine. With the fans at 30% my board temps are 45 and 47 in a 75F ambient and it's not upsetting my TV watching though the outlet of the miner is only about 8 feet away. I can probably make it more efficient with more testing, and I bet it gets quieter.

I'm working on testing other voltage setpoints and will be putting up some efficiency curves and making the code available to anyone who wants to wrangle his own hardware. It'll require a PIC ISP programming device and accompanying software. There's a discussion thread over in the Hardware forum proper about this.

So I mentioned maybe doing a group buy to bring in some S7 or S7LN, and I'd flash 'em to the desired setpoint, test 'em for about a day and ship them within the US. I already have three people interested to the tune of 5 machines. I'm thinking of gathering coin for set of about 5 at a time plus shipping to my facility, plus about 0.05BTC to do the work and testing. It'd be nice if I could get a shipping label for them as well, but we can work that out. Any import duties would also have to be worked out, which is why I was thinking of keeping orders limited to 5 units.

The current plan is to send $420 worth of BTC to address 1CoLDs7XNi8ehyFnGWicUhgBGb7Kw42Ugi, and PM me with a message signed by the sending address and I also need your mailing address. If you would rather use PayPal or some other payment method, let me know. Machines will be set to 620mV cold operation (630mV if 620 is not stable) and 450MHz for around 420W at 2TH, unless otherwise specified.


-------ORDER QUEUE------

Round 1:

2 - navigatrix shipped
2 - IITravel01 shipped
1 - CrazyGuy shipped
1 - fullzero shipped

Round 2:

1 - ZedZedNova testing
1 - zyzzyva testing

Funny you should mention that, the last day or so I've been considering picking some up secondhand and working them up. I've got some S7 proper coming in courtesy of NotFuzzyWarm I'll be working up, but no source for S7-LN.

Which is a shame because a quiet undervolted S7-LN is actually a really good home miner.

I would be interested in an S7 Sidehack. If you do have any you are interested in selling, and could ship to the UK, drop me a message and hopefully we can come to an agreement!

Made you look!

The one you modded for me is quietly mining away in the corner as I type. I had it pointed at several p2pool nodes for a while, but for the last few months it's been pointed to ck's new non-solo pool running his new payout plan. If anyone reading this is curious there is a link in my sig to my miner's stats.

The pool doesn't have a huge amount of hash, but it is growing and it did find a block no too long ago.

Here is a link to the pool message thread:

I would be interested in a sidehack S7... Maybe more than one.

CrazyGuy has some for sale at his ASICPuppy store https://asicpuppy.com/magentoPuppy/index.php/antminer-s7-sidehacked.html

You can also bundle it with the HP DPS 1200 for 70USD per psu.
