BFL ASIC mining board project

Are the sample chips you tested with Rev 2 BFL Chips MrTeal?  Interested to see if these will make any differences as Josh said they are more willing to reach higher mhz in the Singles.

Josh says a lot of things, don't get your hopes up...

Too true, haven't seen him pop his head out anywhere this week either lol

To be fair, he must be having a pretty rough time of it. Cleaning that much egg off of a face must virtually be a full-time job.

   I stand corrected, he's posted on BFL forum so he's not missing anymore

Was it grossly unrealistic promises about the next generation? Or unsolicited rudeness to genuinely concerned and despairing current customers? Or covering his back/arguing about something he was wrong about?

EDIT: I checked - it was option 3.

God, I haven't read those forums in ages, I just follow one or two pages over there. I didn't realise quite how hard they are getting trolled these days. Soooo many posts and threads being deleted all over the place, and so much butt-hurt in general. Some of the posts that have been deleted now did make me laugh though...

I'm not sure if any GPU coolers come with a backplate. I just used some of the ATI HD5xxx style heatsink retention brackets

Anyone know where to source these since I do not have any extras around?

Found some, if anyone's interested. Arctic Cooling makes one

Thanks for that.
I think I am going to try the CPU backplates from FrozenCPU you had linked.

[suprabitz]

did you get the chips?

[nexus99]

Mr. Teal got the chips and the boards should be in production now in Texas. The last word is that the boards would be all finished by early next week with some available Friday-ish.

what thermal tape i must buy 0.5mm or 1.0mm???

[Bargraphics]

what thermal tape i must buy 0.5mm or 1.0mm???

This is what I received from MrTeal

•   A thermal pad is recommended over CPU grease as it cannot be guaranteed that all the dies will be coplanar or at the same height, I recommend this one for reasonable price and good performance

[jelin1984]

You mean we must put first thermal grease
And then put thermal pad and then the CPU cooler??
If put only thermal pad is not ok???

No, I can see how the wording might be confusing.

You only need the Thermal Pad and then whatever cooler you are using on top of that.

Ok thanks under stand


Standard cooling for CPU is ok?

[Bargraphics]

Recommended Cooler #1 – LGA1155 based
Coolermaster Hyper212 Evo
The Hyper 212 Evo is a good cooler to use this with Chili, although the included mounting hardware does make it a little difficult to use. I would recommend using these spacers instead of the supplied ones
http://www.mcmaster.com/#95947a310/=oridfb
and screw them in with some M3x10mm screws
http://www.mcmaster.com/#92005a120/=oribhm

Recommended Cooler #2 – GPU based Arctic Cooling Mono Plus
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7983391&CatId=99
This one is a little simpler to apply as a GPU die is about the same height off the motherboard as the Chili ASICs. It’s nice because it comes with a bunch of little heatsinks you can use on the VRMs if you want, too. I still recommend a backplate, similar to what you would use for a GPU.

Also, I would assume you’re going to be mounting them vertically if you’re doing this, so you’ll probably want to pick up a PCIe bracket.

You can not use most CPU coolers.  There are only a few that work correctly.  This is because of 2 factors:
1) A CPU is higher (taller) than our chips are on the board
2) Some CPU coolers are too small to cover all of the ASIC chips.

Please choose one of the recommended coolers. 
If you do not, you could damage or destroy your ASIC chips.

which is the correct cooler
any model to tell me
thanks
