Topic: [Review] Avalon 4.1 Miner- Summer Mining - Notlist3d - page 7. (Read 14480 times)

Well done @Notlist3d.  Appreciate the review.  Youtube videos are always a plus.  Enjoy your new miner.  Now if we could find one that doesn't generate heat!

I run 3 avalon 4.1's  on my rasp pi model b  the one that uses the sdcard not the mini sdcard. I use a good 8gb sdcard like this
I run them at 850gh each and use 1400 watts .  I use a evga 1600 p2 psu

total 2550gh using 1400 watts.  very happy with this gear it is quiet.

when summer comes round I will drop to 1500gh and 700 watts

Thanks I appreciate the nice words.   I am running a old RaspberryPI Version B. Looking at CPU usage it is sitting around 97-95 percent idle it appears most of the time.  Cgminer is using the most CPU power I have seen it jump to 7 percent only a few times it's pretty solid at 2-3 percent.  This is running with one miner, looking at stats it has a lot more power to do multiple for sure.

With it being summer temps here I did not do much much on the 1.3 TH.  It did get louder where I would not want it in my bedroom at that speed.  I personally am amazed at how quiet it is.  I'm running at around 950GHs.   You could go down even more to ECO and do with even less fan.  But the speed I'm at seems to work great at a ambient temp in mid 70's so far.

Thanks for the review notlist3d

Can you tell what the cpu usage on the Pi is while mining?

Also what is the noise/temp like at 1.3TH?

Thanks

• How do you get in the case? There are 4 screws on the side of the fan compartment after the fan compartment will slide out, then 2 more screws on the sliding panel.  After all 6 screws are out you can easily slide the panel
• If you are completely stuck who do you talk to? Canaan-Creative has a great support team and are very helpful.  They helped me when I could not detect my miner.
• Is the Raspberry PI reliable? So far it's been great.  I am using a Raspberry Pi V1 B, and with one miner it's always has had over 90 percent of cpu on idle.
• What if you want to use a TP-Link? Make sure to get the newer model of: TP-LINK TL-WR703N the older model of TP-LINK TL-WR702N lacks the usb port needed

In this review we have went over most of the technical spec's already.   In this section we will hook up multiple Avalon 4.1's.  They will be running the same under clock mentioned in first part off the review. Below are parts needed in addition to parts in first review.

• Standard power supply with 4 PCI-E 6 Pin adapters.  Power depends on what speed  you will be running the miners at (In my under clock each extra miner you need to add a PSU with over 550 watt's also at underclocked you only need 2 PCI-e cables(One on each blade).)
• USB Hub to connect 3 to Raspberry Pi

1) The Miners
Below are images to showcase the miners.




2) Install
Adding a miner is extremely easy.  You have already done the setup in the first review.   It was literally as simple as plugging a hub into the Raspberry PI, and plugging the Avalon miners into it. Below is a picture of Raspberry Pi with a hub and 3 miners plugged into it:

The Avalon 4.1 miner is a solid miner from it's metal case to it's performance with under clocking capabilities.  In the worlds of Avalon "Avalon4.1 – 1.3T consists of 40 A3222 chips, with improved heat dissipation, which can be controlled by Raspberry Pi or TP-Link TL-WR703N."  Below is list of items you need to buy in addition to miner.  Ofcourse some of you might have these in your parts pile and already be a step ahead.

• Standard power supply with 4 PCI-E 6 Pin adapters (up to 1000 watts depending on setting, also at underclocked you only need 2 PCI-e cables(One on each blade).)
• Raspberry Pi or TP-Link TL-WR703N
• Network cable

1) Unpacking
The miner had a decent sized trip from from EHash to my door in middle of US.  It was shipped via DHL and made it to my door in 5 day's. First thing you will notice is a box.  Mine made the journey without any problems as you can see below.   And in the second picture you can see it was well protected with styrofoam around the miner.

3) Install
The install is not hard at all with the guides posted on EHash: http://downloads.canaan-creative.com/people/lili/doc/controller/

First you will need to flash either a Raspberry Pi or the TPlink.  I personally chose raspberry pi as I had one laying around.   The main guides I used were:

1) The Raspberry PI SD flash guide: http://downloads.canaan-creative.com/people/lili/doc/controller/Raspberryreflash.doc
2) The Raspberry PI settings guide: http://downloads.canaan-creative.com/people/lili/doc/controller/Raspberrysetting.doc

As far as a general guide you will reflash your Raspberry PI with a pre-made image of a custom DDWRT install for the Avalon hardware.  After flashing you need to connect to the Raspberry PI.  In my case I had to log in and change the IP address to 192.168.1.X IP.   I would say it's a 15 minute install if you don't have any trouble.  I did run into some trouble and Canaan-Creative does have a great support team and they helped me though it.

4) Running
For these results I am running at a under clock

Avalon 4.1 running with settings shown below:
MM Ver   Chip Freq      Voltage      Hashrate          Power usage
4.1       420:390:360    7625         980G              542Watt        *A special thanks to philipma1957 for finding these settings Link to more settingss

• Below is the advanced GUI showing the miner running:

• A Kill-A-Watt showing watts used:

• The air temperature before and after being sent through exhaust:

• Sound:  This miner is crazy quiet with a underclock and fan at default of 20 percent.  I went to take a YouTube video to show off how quiet it is.  I had to turn off my overhead fan, my projector, and close my window.   And still could barley hear it.  Link to video: https://www.youtube.com/watch?v=d7UTdo_4AaQ

5) Conclusion
This was a perfect fit for me getting ready for summer mining.  I was able to run it at a under clock making it a very efficient miner. The heat exhaust is manageable even though winter is over for me. The install was easy with use of the guides, no big surprises during my install.  And only problem I had the support was great and nice to work with.  It seems to be built with a solid metal case, and solid performance.  The biggest surprise was how quiet this miner can be.  It is the first miner I actually put in my bedroom and cannot hear it across the room.   I have other miners from big and small, water cooled, and nothing is comparable on so little sound.  I will keep it running and post how it goes overtime but it is a very good miner from my experience so far.
