Attention:

Below is the corresponding default frequency for S7 miners with hash rate and batch #.



With overclocking you lose the warranty.

How are those temperatures on your miner? Does it perform better at slightly higher temps?

Mine tends to gain an extra 100GH when it runs around 55C. I haven't tried going for below 50C yet though.

No need to put down power consumption, their efficiency is basically fixed @ 0.25 W/GHs or 0.275 W/GHs ATW (depending on model) regardless of clock speed Edit: if your input voltage stays the same.  From Dogie's Antminer S7 setup thread, not sure who to give credit for it if not him: Edit: I assume this is at roughly +12V input

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?

My batch one is pretty much a dog
My batch two is pretty much a unicorn.

That said both of them can do 5000gh if you give them 12.5 volts.

This gear loves a hot psu.

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.

 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.

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.

Hi Everybody,

What batch is mine? Since the seller didn't specified?
What I have in the sticker is:
AntMiner S7 Submodel:S7_4.86

Model: S7 Version:V2.01

All the best,

Geotete

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

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.

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.

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
