nice brick ! happy mining
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 Are you going to push the chips harder to get more per chip? Get some oil or immersion cooling?
so extreme OC and immersion just does not pay offThanks. 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!

Some more speed updates as promised 
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 sandwich!
Keep us all updated on it.

Sorry, Dude,

I like the heatsink. Did it come with 4800 rpm SUNON?
Did you happen to order one too?
Nice, i love that SUNON
Yes, but less chip board

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?
