Re: My Impression of Avalon Machine

I'm a first batch Avalon buyer in China, purchased RMB via taobao / alipay.
Avalon sent the machine on Feb 18 & I got my first machine (*: my order is 3 machines) on Feb 20 and it hashes well on HHTT.
The first buyer in China got his machine afternoon or evening on Feb 18 (+0800) I think. Mine delayed for 2 days.

Currently even someone in China get their Avalon (5 is confirmed including mine, no more than 10) in their hands, they each has only ONE machine delivered no matter how many are ordered. Avalon planned to ship the remaining at the end of Feb.

Here is some unordered summaries & notices that may help you prepare.
You may ask other related questions & I'll try hard to answer.

Tip will be appreciated: 1HFhtvzNEiy9eooLSJRMyZ1XB2FXgYGvCH

About the system:
1 the embedded wr703n is MEM modded.
original 703n is 32M mem, it has been modded to 64M. but no flash mod. flash size is 4M, the same as original.
those who would like to have ipv6 may become disappointed. may have to use another machine & connect via USB.
(if you prepare to do so, longer USB A-to-B type cable & teardown is required)

2 the miner is cgminer 2.10.5, should be the same as the git tree. it should have no memory leak bug (for stratum).

3 fan control is a little buggy, should be fixed by xiangfu soon (already in tree).

4 the jffs2 partition is so small (320k) & can only hold config files.
that means cant upgrade cgminer via jffs2 unless done firmware repackaging. cgminer is installed in squashfs.

5 default IP is 192.168.0.100/24, gateway 192.168.0.1 (you may have known)

About the packaging & machine:
1 package include a power cable, an wifi antenna (SMA connector, gain is 5dBi I think) and the machine it self.

2 no instruction included (hopefully yours may include one).

3 to teardown the box, use Hex Key of size M4.0. your fingers may get hurt, put on gloves first.

4 the USB cable may get dropped from the board during shipping, make sure there is a blue light on the 703n board when powered on, or you will be in trouble...

5 there is an USB hub included, unopened 3M double-sided tape pasted on the back of the hub.

6 the PSU is Antec EA-650 Green (80P Bronze, not the Platinum one)

About running:
1 you may wish to move all the 3 modules to the left, can lower the temperature about 3 degree.
aware: this may increase the difficulty of installing the 4th module (if released in the future).

2 64300-64500 MHash/s measured by work units, 67000 MHash/s displayed by default.

3 HW Error about 0.55% ~ 0.65% @ 282. ~0.75% @ overclocking to 300. hashrate increase by 5% if overclocked.
I recommend not touch the last 45 in the options.

when do overclocking, there are some duplicated shares appeared, not sure it is cgminer or HW's fault.

4 please DO preconfigure the diff of ALL the pools (including the backup ones), var diff may slow down the machine at first until the diff is adjusted.

5 fans must remain 2000 RPM/min to keep the heat out.
with optimized fan control, fan2 is 2640, fan3 is 2280 while temp is 46 deg (incoming air is 28 deg measured by temp1).
the noise level is comparable to a multi GPU cluster with 60-70% fan. I dont have a measure device to get the exact number.

6 there is no thermal grease between the bottom of the heat sink (of the modules) and the upside of bottom aluminium board (& it is a little hot).
you may wish to mod them and do some work outside the machine to cool down the downside of bottom board.

Note: I may update the main thread for updates.

Doesn't that negate the following?: (in yellow)

................ and everything will be clear then.
This includes also, that the other customers will know when they get their units?
Currently you would have sent about 108 units!

Ah actually, this is probably something I should update, the original plan is to assemble one and send one, of course this isn't working out, we currently have sent a batch of 53 to a different route, as it currently stands, this 53 has the biggest chance to make it out of the country, then we can attempt again if the news make it back to us before Feb 2. which is the deadline for getting things out of the country before CNY.

Honestly, this is probably something we underestimated and I'd like to personally apologize for having similarity with BFL, it is so pathetic. Then again though, since we did originally promise to ship everything out before Feb ends I don't really see a problem with this.

As for new information, we are still dealing with the custom issues I've previously mentioned, but Jeff should receive his units within this week, and everything will be clear then.

You seriously believe that shipping one unit to one customer will make you earn 750k$ in preorders? During the weekend, maybe?

Dude,
It is up to us. He has nothing to believe in. We are the ones to decide if he will get 750K or zero. From what i see here the answer is yes he will sell 500 batch in 20 mins max if the site does not hang:) Let me refresh your memory first batch 300 units was sold for less than 20 minutes or so even though Avalon was about three mounts behind from shipping compared to BTCFPGA and BFL promises


Couldn't have said it better myself, I'm writing up the batch #2 pre-sale thread right now.
