Topic: Review of Avalon-4.1 - page 4. (Read 11124 times)
Avalon still making acis miners. Wasn't aware they where still making asics any more. Looking at their cost of equipment and hashing speed and power use is stupidly expensive. 1300watt for 1.3TH can go grab me an antminer s5 that is 1.1TH and using 500w at most. 1/3rd of the energy use don an avalon machine. If avalon got their act together from being the first to release asic technology and asic miners to reducing theri energy used and then having a good miner they would again have a good miner. Right now their way over priced and way under energy effective
any news on this new review?
I got tracking for the new miner. I will look to do a long followup on this as a 2 miner setup very soon.
I went to order more today had trouble doing so about 1 hour later
valkir I got your pm explaining the issue.
I got an email from ehash saying 1st order was paid for. I am hoping this is a good order. as I do want to show a 2x machine setup.
It was 3% and now should be 5%
Im waiting for the new coupons.
PM me for one! Its free!

I have to say once again this is really quiet gear.
Yes, and while there is winter it makes a great leg heater
https://bitcointalksearch.org/topic/--7216
Mine already is, max clocks and still silent (with a fan RPM cap). Quieter than any PSU I can put it with other than an RM1000.
I am going to shift to these over the next month. run them at 850gh using 480 watts each. and when the summer comes set them to eco mode at 500gh 244watts each.
I will try to see if they are stable with 2 then 3 then 4 units on the rasp pi.

I decided to order today. So I purchased a second avalon 4.1
valkir helped me get the demo one and was helpful in ordering a second one today.
I will post how 2 run on my rasp pi. I hope to get it some time next week and do a series of photos and tests with 2 running vs 1.
I may order a third one and do a 3 machine set of tests.
I have to say once again this is really quiet gear.
I may end up selling off my sp20s and my s-5 and just keeping 3 or 4 of these for the summer.

Can anybody post what are the settings for "Chip Frequency" and "Chip Voltage" when running in ECO mode?
Furthermore, can "Chip Frequency" be modified at any interval? Is "Chip Frequency" directly related to "Chip Voltage", is there any table for all possible combinations of "Chip Frequency" and "Chip Voltage" (combined)?

chip frequency is directly related to
chip frequency setting on the custom page
I use 370:360:340
Default is 450:390:370
use custom
Set your volts to 7750
use auto voltage =true.
and then tinker with chip frequency setting you will get lots of results for frequency. auto volts will find the best volts for that freq.
volts can be set at:
8250
8125
8000
7875
7750
7625
7500
7375
7250
7125
7000
6875
6750
6625
6500
I do all custom settings. I don't ssh.
I found with volts on auto the software does the work. my current custom setting is :
I get this result and use 480 watts to do it. this is 480/854 = .562 watts a gh
if I go to custom I get 244 watts and 500gh that is .488 watts a gh . diff and price does not require me to do eco right now.

Are these setting accurate:
wall power reference(W) hashrate(GHS) comment
400 800 echo mode
570 1000 normal mode
950 1300 turbo mode
Assuming they are. I can run 2 Avalon 4.1s using my Corsair ax1200i power supply at normal mode. Is that right?
On Normal mode what is the dB at default settings?
Also for reference, what is the dB on turbo mode?
I will be putting these in my office so i want to make sure they are quiet

db should be under 45db. you will be borderline to do the corsair AX1200i using custom settings, the stock settings you have are not accurate.
Now I have the older firmware as I go with if it works with old firmware don't ever do new firmware until 3 or 4 others show it works.
The firmware I have does eco mode :
244 watts and 500 gh
My custom setting does 840gh at 470 watts
so you can do 2 at 1680gh using 940 watts
settings page
picked custom
my results have been very stable using a rasp pi older model B

There are no settings to achieve those numbers in the real world with the factory firmware which is:
250W 500GHs eco mode
~650W 1000GHS normal mode
there are some in between frequency and voltage settings for 450W and 500W (not defaults) which give 850-900GHS more info on that in this thread and my review thread
450W 850GHS
500W 900GHS
I have not gotten around to turbo yet will tackle that tomorrow
As for quiet, using either of phils or my settings for 850-900 range you will have guaranteed quiet and even on stock speed its quiet just not as efficient

the results below fan is 1100 rpm quiet but if you ssh in and set it slower the unit is still cool enough.
Alternatively you can just set the max fan RPM to 30 [or around there for 1200rpm] if you know ambient is going to remain sensible. Ie don't cap the RPm off then put it in a 50C farm
Either way, 1100rpm is quieter than a Cube. I've missed this.
I am running my s-5 and the avalon-4.1 In a spare bedroom. The window is open ½ to ¾ inches.
This gear would really clean up if it could be sold at a lower price point. It is truly quiet the fan at 15% is under 1000 rpm
The settings I have finished with:
Mining Mode(Default: Customs)--------------------------------------------------------- Customs
Chip Frequency(Default: 450:390:370)------------------------------------------------ 360:355:340
Chip Voltage(Default for 4.0: 8125, for 4.1: 8000)----------------------------------- 7250
Automatic Voltage(Default: True)------------------------------------------------------- True
Fan%(Default: 20%)---------------------------------------------------------------------- 15
gave me this over night watts are 460-470 at kwatt meter that is about 0.56 watts
sound meter was 38db to 42 db
This miner actually is a true home miner the sound levels are wife friendly so when all is said and done I can keep these custom settings for now and then keep this miner on stock eco mode for the summer. Use it to mine solo to keep in the game.
that is 500 gh and 244 watts = .488 watts a gh

yeah with the custom settings of
Chip Frequency(Default: 450:390:370) 360:355:340
Chip Voltage(Default for 4.0: 8125, for 4.1: 8000) 7250
Automatic Voltage(Default: True) True
the results below fan is 1100 rpm quiet but if you ssh in and set it slower the unit is still cool enough.
I get 840gh use 460 watts about 0.55 watts a gh and 38-45db with stock fan. I am done with custom setting tests for efficiency 0.55 watts and 840gh is good enough for me. Tomorrow I tweak fan settings.
