Hey,
A quick question, since I have also the S7 B7.
A quick question, since I have also the S7 B7.
You probably do not have Batch7 miner.
[edit]: and whats that with the Asics # 54?, mine says 45
3x 45 Asics is AntminerS7 batch 6 and Batch 8

S7 B7
Hey,
A quick question, since I have also the S7 B7.
Did you just put the frequency up to 687 with the standard firmware, or you first updated the firmware?
Is this hashpower created to just making the frequency larger?

i feel alot more comfortable around 12.5V on the s7's tbh regardless of oc or uc.
i think max is 13V on load for the bm1385 chips & also as per bmt recommendations.
i could be wrong .. someone with more tech knowledge pls do chime in.

Going by the BM1385 Data sheet you should be ok even with 14V although I agree that 13V is a safe maximum. Also remember this does not apply to the 135 chip Batches 6 & 8 where you should stick with the Bitmain spec of 11.60 ~13.00V at least until we have confirmed that it is fitted with a Buck Converter, in which case there will be no value in varying the voltage.

It is good for you as the 4000 watt 2x psu you sell has the ability to do more then one voltage.
In fact I no longer think atx psu's are worth using on the s-7 or the avalon 6 unless you have 120 volt power.
I think your adjustable units that you are selling for j4bberwock are the way to go.
Yes I am excited to produce some and try them out. The one demo model I got from him I had to send out to get the side/front panels figured out. Should be receiving the PCB's and start soldering this week.
a naive question, perhaps, but are 2880W PSUs capable of slightly more than 12V or only 4000w "beasts" can do it?
I am just curious.
The IBM 2880's typically put out slightly over 12V, but only the 4K boards will have the option to under or over volt at this time. I believe J4bberwock has plans for more server PSU's that allow voltage control, but I'll leave that up to him when he's ready.
afaik, the 2000bb's can be adjusted up to around 12.5-12.8V & down to about 11.6V in it's original form. i got mine to 12.5V with loads at the pcie cables attached to the s7's. you can even go higher than 14V up to over 200A on the 2000bb's but will have to mod pins with pot + resistor.
the 2880w not sure if the voltage can be adjusted. but i'm sure that the stock voltage would be around 12.2V range. that i hope j4b can chime in.

i posted up some pics on the s7 thread https://bitcointalksearch.org/topic/m.13130691
Amen to that... Would love to know if efficiency has decreased at all at that clock speed, if you ever get a chance to measure ATW consumption!
Temperature sure came up overnight eh? Looks like hashrate is holding steady though, you going to leave it at that clock?
Yes, will leave it at that. I see my miners as super-depreciatory assets.

Could you post a screen shot of a 24+ hour run time please?

Hi, again,
Since mine is a late batch 5, here it goes:
All the values, are in a controlled temperature room, at a steady 14ºC all year around, with a humidity of 60%.
I don't know the power consumption, but I have 2x 1250w HP PSU, powering the S7.
The values, are a average calculated, at 48 hours each.
http://www.dfagundes.com/Foruns/value.jpg
Since, I don't know how to interpreter this values, your help is appreciated!
I don't know if have any gain in going at more than 625...
All the Best,
Geotete

Hi Everybody,
What batch is mine? Since the seller didn't specified?
What I have in the sticker is:

That's batch 3, 5, or 1. That's the best I can do at narrowing it down.

yeah both the s-7 and avalon 6 have show they want a hot psu 12.2 12.4 12.6
your new 2000 2x setup will be very good for them. better then the 2880 units. I want one when you get them in.

Efficiency is only fixed for a single supply voltage. If people are running at more or less than 12V it will change. An interesting measurement would be peoples actual supply voltage measured at the PCIe connector?

Of course, sorry I meant for a given input voltage. I.E. if your power supply stays the same, over/under clocking will have little to no effect on YOUR unit's efficiency, only the heat generated/overall power usage. I'll take voltage measurements at the plugs when I get a chance to visit "My Friend".
It's interesting both how important actual voltage output of a PSU has become w/ string design, and how picky some of the new hardware can be about under-volting.
