Is a 0.5W/GH achievable on the Avalon4, by Undervolting and Underclocking?

Yes you can get 800gh for ~410w. Its the eco mode. Grin

Have you tried mining with the eco mode? What was your Power consumption at the wall?

The specs on the Avalon4 site claims 570W / 1THASH and this review reports 694Watts.

I was on 8125 for the voltage. I changed it to 8000. Need to recheck the meter.
Doing it right now. Will post the new pic in 30 min. Grin

Edit: I click on ECO mode and bring me to 500gh for 250 w
Im on the firmware 4.1. Will need to check with Avalon for the specs.

Many thanks for your effort man!

If yes, I would be interested in the final GH/s value at 0.5W/GH, to find out how it compared with the S5 and SP20.

Yep! This is a real home miners. Grin

If someone want a Avalon4 PM me I can manage something.

bumping this as the avalon4 may be nice if quiet mining is your biggest goal

I read this can do 820gh and 400 watts. Or maybe it was 800gh and 420watts.

An underclock would be nice to test.
The evga 1300 g2 should do 90 or 91% at 690 watt level.

see review below

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story3&reid=349

K-watt meters can be + or - 5%

I have 2 meters 1 of them reads 20 or 30 watts higher at 1000 watts then the other .

Thanks philipma1957 for the clarification on the meter.

I will also try the underclock. Grin

I am too lazy to find the photos I took with the same gear running and the two meters. but somewhere. I posted I have a high meter and a low one. In fact I ordered a third meter to test and run a thread showing that the kwatts are only so good.

It comes on thursday .

I think I will run a short thread about it.

I changed the voltage of the chip to 8000. It gave me better hashrate and lower watt. I will post a picture of the wattmeter tonight. Grin

If you leave auto voltage on I'm not actually sure what will happen to the final voltage, or if the 8000 will just act as a starting voltage.

Thanks for the review.

What PSU was used? Would like to know how efficient it is.

Its a EVGA 1300

0,7 watt/Gh is not good unless you had free power. I wonder if you able to downclock the miner & see the efficiency.

He's on an EVGA 1300 (helped him set it up). Its probably losing some efficiency being down at 40% loading as he's getting the same power draw on his 4.1 as I am on my 4.0. And 4.0 comes with slightly better DC/DC and automatic voltage control. Its not as advanced as Spondoolies' which varies speed and voltage, but it does keep minimising the voltage to find what is the absolute minimum you can get away with while remaining stable, for a given speed.

This is my first official review. I have not been paid for it. I made it to help people make a better choice.

Chips = 40x 28nm Avalon 4 A2322
Hashrate = 1000GH
Power Consumption = ~690W

- This is after 1h

There is a nice thick foam to protect each side.

All parts are wrapped.

They send 2 connectors. To be able to connect multiple Avalon together.

Avalon 4 VS S5 Size

And now the web platform!

Clean and easy to use. I got a steady 1Th without any problem.

The sound is awesome. One thing that I really didn't like on the S5 was the sound. The Avalon4 do almost no sound. The fan run between 1600 to 4000 but even at 4000 the sound is not a problem. I guess for a home miner, the Avalon4 could be a better miner for the sound.

With the S5 you needed 2 fans to drop the sound. With the Avalon 4, you need a raspberry pi if you dont want to connect it to your computer directly.

The quality of the enclosure is really good. The metal is thick and the part seems perfectly assembled.

This is the raspberry pi image for 4.1 firmware.

I hope this would help you to choice the best miner.

I got a S5 and Avalon4. I do believe each one got is + and -

Price on 27-01-2015 : Avalon 4 = 1.87 BTC + 25$ of border = 1.97 BTC
S5 = 1.427 BTC + 90$ of border = 1.77 BTC

If you have any problem, do not hesitate.

EDIT: If you are running on 4.1 firmware, be sure to be at 8000 on chip voltage.
