Im trying to make heatsinks for these boards to cut costs,

the heatsinks are 84 mm high and 80 width and 250 mm long. so you only need 2 of them for each board. they are high power heatsinks.

Here is an example of the heatsink type, only wider.



here is how it should look on the board (its a scetch without the work done on the bottom).


I have done all the measurments last night with a caliper.

Marto any news when batch 2 will be shipped, its been over a month now since you received my chips. ive emailed you on your site, 2 weeks ago and no reply.
would like to know whats happening with those.

you going to be offering any compensation for late deliveries now. awaiting 25 boards  Angry and counting

 No offense Guyver, but he hasn't even shipped batch one out. Hopefully he will not ship out anymore batch 2 like the mistake made last week. I just got my first partial shipment today 6 of 50. I know its been over a month for you and I hate it, but it has been over 10 weeks for some of us.

I think cooling on 1 chip is not very good so it works @ let us say 75+ percent
I would sugest to us 75 in this tab

Can someone provide me with some dimensions (metric system pls)?



A= total width (without heatsink)
B= tatal height (without heatsink)
C= center hole to center hole
D= edge of board to rectifier
E= edge of board to center hole
F= center hole to center hole


Are the tiny capacitors near the minion chip (on 3 of the 4 sides) lower, higher or the same hight as the minion chip. ?


a=250 mm
b=250 mm
e=c=f=80 mm
d= 81-83 mm ( some variation during PnP)
caps: there are 2 models one is lower the other is higher than the minion

Is that normal?


 [2014-09-25 11:16:46] HEXM 1 restarting due to low hash rate (378456.823541 < 3
81173.760000). Uptime 190.023406 secs

I dont think that 378Gh is low hash rate (400+/- is 378 in tolerance).

Now is every 190sec hex rebooting.


You can try to change HexM reset board due to low performance in % setting.
Default is 94, try change to 90 or 85  Smiley

So which board is this? I am looking for your test result  Grin

I have 10 ARCTIC Freezer 7 Pro Rev. 2 CPU fans for sale. I will try to sell them as a full lot. I purchased these for the HEX4M boards. Each board needs 4 fans so I was slowly buying them on sale at Newegg.com. My situation has changed so now I don't need them. Willing to sell the lot including shipping in the USA for .45 BTC. These are new fans that have not been put on a board. One of the fans has a smudge mark on the cpu grease but most people replace the OEM stuff and use better cpu grease such as Arctic silver. If you want to purchase but are outside the USA I will sell but you need to pay for shipping and excise duty.

any idea whats wrong?

after start it is minig about 2min, than its stop and blinking red.

You might aswell have wrong atached coolers to the board, i did have the same problem  at the begining

When I set up my first miner, I was unable to get 400 gh with 1024hz x .820v, (It, in-fact was doing about 1.5gh, dropping and then becoming a zombie) but that is probably because I am using a 520w psu with only 16A + 18A power. I was, however able to get a good 360gh by setting the frequency to 920 and the voltage to .780. The miner has been up and stable now for 3 days. I think it is worth a try.
