I got lucky and received my miner in advance.
What I can tell you it rocks! As you can see it works stable with almost zero HW errors and low reject rate. I am sure I can push it little bit forward. More details + pictures power at the wall later.
The screen shot is from my i386 PC. I will move it to my tplink farm and give you some shots of it with a short details about options.

Nice, you got a picture of it?

Sorry, Dude,
I just had the chance to do it :

glad you already run it
You can push it a little bit i think:

Gratz loshia  :)
I like the heatsink. Did it come with 4800 rpm SUNON?

Yup I did not pay attention to brand but it is about 5000 rpm ;)
Did you happen to order one too?

Nice, i love that SUNON  :D
Yes, but less chip board  ;D

Nice sandwich!

Keep us all updated on it.

Some more speed updates as promised ;D

I got it 250GH stable!!! Some things to note:

cgminer clock is set to 250. To find out actual ASIC clock you have to multiply by 4x250 = 1000. In theory I have 8 chips , 32 cores each 1000 clock which equals to 8*32*1000=256000 or 256 GH. You will ask where are my 6 GH. So bad news I got 5 dead cores/engines which does not bother me much. That are the chips received from the factory and I can not do much about it.
./cgminer-api stats | grep engines
   [Chip1 Engines] => 32
   [Chip2 Engines] => 29
   [Chip3 Engines] => 32
   [Chip4 Engines] => 32
   [Chip5 Engines] => 31
   [Chip6 Engines] => 32
   [Chip7 Engines] => 31
   [Chip8 Engines] => 32
 
So I should be getting in theory 251 GH so basically I am there!!

More good news – the max clock rate should be 275*4 = 1100. I am not feeling like I will push it to the limits but I can tell you that all of you shall be getting around 260 GH. Have in mind cooling is very important. I am lucky because it is winter now and my room temp is around 10C. I know that up to 20-22 C is ok.
More Updates to come tplink and cgminer options

Nice.

Are you going to push the chips harder to get more per chip? Get some oil or immersion cooling?

No i am not going to. Next step will be 255 to reach 260 GH and i will leave it there. That would be it. About immersion cooling i have good experience with it. It does not worth booth the effort and expenses. Besides i wana make some profit ;) so extreme OC and immersion just does not pay off

Thanks. Just wondering who might be testing the limits of these chips. Definitely profit possible I bet with this board hashing right now.  Will be following GREAT JOB! And Good Luck!

nice brick ! happy mining  ;)

As promised some cgminer stuff explained here:

Morning fellows,
My board PIC FW and heat sink and fans were upgraded yesterday. What I can tell you it rocks. Here are my results after 14+ hours nonstop mining

http://s30.postimg.org/l908iqo5t/image.jpg (http://postimage.org/)

Some things to point out:
1.   My stats are not settled yet, because I am mining at 512 diif + filtering out nonces inside ASIC chips  which do not meet it. The board is making 270GH stable and there is some room for overclocking. BUT I do not feel brave enough to do it and I suggest to all of you not to push it too much.  We are hiiting the limits of hardware especially voltage regulators so overdriving them for a long period is not good idea at all. This is my personal opinion.  I do hope that there will be precise measurement of power consumption very soon. I am using single rail psu rated 55A/12V. I think the bottom line is at lest 45A, to be on a safe side
2.   Tplink+cgminer worked rock stable without an issue. My pool reject rate is 0.12% only which is golden! I am not commenting my HW error rate at all ;) Technobit team did their job just perfect :D
3.   What I can tell you that all of you should be able to get the 260Gh advertised at clock around 260 and voltage around 1000 mv. You have to experiment a little bit to find your sweet spot though.  
More updates to come  

New photo of new heatsink/fans please!

45A = 540W is high for 28nm though! 0.5GH/1W is like an AntMiner but that has a huge heatsink to dissipate that heat.

I'm not a fan of the Sunon 4500rpm leaf blowers. Can't wait to get my hands on the Hex8A1 and see if I can make it quiet. I like a challenge!

I guess you can always throw more chips at the GH problem like AntMiner did if you can make them cheap enough.

It's a shame it wasn't a 16x chip board then it would really have rocked.  8)

Gator
I am the kind who like to be insured. So 45a is at least 20% on top
If you want 1w/GH you can always have it undervolting/clocking the board no problem

Yeah, if I can get 200GH out of them with quiet fans somewhere around 0.7GH/1W (like the Bitfury) I'll be very happy.  ;D

I'll post in "hands on" with the results when I get mine.

A friendly advise start looking for two quiet fans for every board you have ordered. ;)

loshia what are the temps being reported back?

No temp sensor on the board dude.
But it is getting hard to touch if not cooled right ;)
I would say up to 25 maybe 30 celsius you will be ok with stock fans an heatsink. My room temp is not more than 15 because of the winter so cooler is always better

Good to hear. We keep our "mining room/datacenter" at about 18c but I heard these things need some space to themselves.

how much you want for the miner? 1,4btc

First batch (only 30x units) cost €1,500
BTC right now = €511

I don't think anyone will part with one for 1.4BTC = instant loss.

I know you're hinting we could have bought an AntMiner, but AntMiner was 1.95BTC and BTC was €615 when these orders were taken.
Back then it looked the same $/GH, but with better GH/W, but sadly not now, such is the risk of buying on specs.

I was curious what kind of heatsink upgrade  ;D

New image for TL-MR3020 + cgminer 3.12.3 patch 0.2.0 Milestone release (http://www.megafileupload.com/en/file/497695/0-2-0-rar.html)

Do I need to reset the TL-MR3020 back to factory settings for it to install?
If so how, do I do that?

Thanks.

Hey,
Read the change long :)
Use *sysupgrade.bin for openwrt preflashed router or *facory.bin for factory FW router. As i call it a virgin one ;D
Short answer no, but after you install it go to web interface cgminer configuration andfeel all blanks with default values quoted and Save+Apply  

No need to reset, just browse the new image & hit flash  ;D
But i usually use factory bin, i am prefer "fresh install"  :D

nice toaster! =) *where can i get one?

Got mine today, working perfectly, stable 260Ghs on a tl-mr3020 with patched firmware and default settings.
But this thing is incredibly noisy ...

Gratz gcube  ;D
