Guy’s 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. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs2.postimg.org%2Fwhob311rt%2Fimage.jpg&t=665&c=4SYd3eTMduoYPw)

Gratz loshia ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I like the heatsink. Did it come with 4800 rpm SUNON?

Some more speed updates as promised ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) 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 ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs29.postimg.org%2F8yf4rjrfb%2Fimage.jpg&t=665&c=gCJTvYS2H_dIVA)

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

Nice.

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 ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) so extreme OC and immersion just does not pay off

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!

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 ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs30.postimg.org%2Fl908iqo5t%2Fimage.jpg&t=665&c=qOrykrT48qy9-A) 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 ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Technobit team did their job just perfect ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) 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

My board PIC FW and heat sink and fans were upgraded yesterday. 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. ![Cool](https://bitcointalk.org/Smileys/default/cool.gif)

So 45a is at least 20% on top If you want 1w/GH you can always have it undervolting/clocking the board no problem
