Sorry for newbee question but do I need to buy and additional controller to manage avalon 7 or this is similar construction like antminer?
Groupbuy will be good idea, anyone?

good. next question do you still work with Yang of block_c in San Francisco ? Or must we order direct from China? Lastly if I buy 2 or 3 or 4 and something breaks will I need to do warranty with China? I am in NJ and shipping to China is costly. I had bad luck with the S9 and would like to load up with your gear. I just do not want to have same issues of breakdowns and have to send gear to China for warranty service.

My hosting provider told me there was MOQ of 100 units. I sure hope that information is incorrect!

100 units! ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif) If that is true, I hope that they still have some eye for the game to support home miners and take a community group buy with a smaller quantity (like for example 10 units MOQ). edit, found this:https://github.com/Canaan-Creative/cgminer/blob/master/driver-avalon7.h#define AVA7_MM741_ASIC_CNT 22 ...
#define AVA7_DEFAULT_MINER_CNT 4
See this code. There is also a 88x A3212 chip version of the Avalon7. ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) Canaan Creative AvalonMiner 741.

I hope there is no MOQ. I may do a group buy if anyone is interested in having them hosted with me at CryptoBoreas (Labrador). But if not and there is someone trustworthy that will do a group buy, I'd be interested.
Alan, I'll have to tumble the numbers. If they're ok, I'd join in your group buy if there's a MOQ.

I don't know about blockC But A7 is much more reliable than the S9

I am not happy with these numbers at all. 6TH at 900W for $888. At this point, the only good point is that it should be of much higher quality than offerings from BMT.

I wonder if AvalonMiner 741 with more chips could be a little more efficient with efficiency friendly settings. Maybe 7Th/s / 900W ?

Yep, that also raises the question if undervolting and downclocking could lead for a better efficiency. For example if you could run one A7 5000Gh/s, 600W. That would bring us to 0.12Gh/s per watt efficiency.

72 chips across 2 boards means 36 chips per board. Based off what I've seen, 14/16 likes the 0.4-0.5V range, and there's no good way to stack 36 chips into 12V to get this. I wouldn't be surprised if it was a regulated string of 2x18 chips per board with a dual-phase buck in the 8V 25A-per-phase neighborhood. If that's the case, undervolting might be possible - either directly through the config like the Avalon4, or by a hack like S7.

I know downclocking makes your rig last longer because there is less heat. If you do not downclock too much, it will have no effect on the efficiency.

Downclocking by itself has almost no effect on efficiency.
Undervolting (where it works) is where the efficiency gains happen, but usually requires downclocking for the item to work at all when undervolted quite a bit.

This may be a question for a different string but with the Avalon 7 using under 1KW do you need to connect the PSU to every available connection? I assume yes but I have a bunch of 1300w power supplies with only 6 PCIe cables.

well my guess is take 4 of your six cables and plug them in to separate corners then find quality splitters for the other 2 cables turning them into 4 plugs then every board has 1.5 cables like this which maybe good ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FCD4V1B5.png&t=665&c=WWAgW9DGVe6JMw)
