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.

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.

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.

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

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.

Attention:

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

With overclocking you lose the warranty.

Please post your results, there are a lot of frequencies and setups, so please post the following in this format.

Batch: Batch#
Frequency: Freq#
Hashrate: Hashrate#
Power consumption: PowerConsumption# (If possible)
Fan Speed: FanSpeedPercentage#
Avg Blade Temperature: TempInCelcius#
Hardware Errors Per Day: HWerrors#

For example:

Batch: 6
Frequency: 575
Hashrate: 3.82TH/s
Power consumption: N/A
Fan Speed: 35%
Avg Blade Temperature: 54C
Hardware Errors Per Day: 3/day
