You'd have to take that up with bobsag, but it's possible we could work something out. How long do you expect it'd take for you guys to do their entire batch? How many boards is that? I'm not going to make any guarantees about large quantity anything at all without a) more information about the problems and fixes, and b) consent from owners or otherwise responsible agents.

Haven't heard anything back yet. Not terribly surprised about that given the state of things, but we're definitely interested in helping solve the problem.

sorry did not have time to shoot pictures.
Any way tomorrow we are finishing sendings to end customers and Monday will prepare what is left to minersource.
I suppose I can send these without wire /pic fix and you'll do it for them ?

That's fine.

PM sent. We could reflow BGA ASICs but don't have the X-ray equipment to check 'em without turning 'em on. Finagling 0805 components is a regular occurrence around here, and installing, replacing and flashing microcontrollers is also pretty standard fare.

From what I gather, most of the problem is bad microcontrollers - appear to be about a TQFP-64. We could probably swap and test 50 boards here in a couple days, if we had 'em to work on and a bit more info from you on the specific issues. It would get my hosting customers up to speed a bit quicker, which I'm sure they're in favor of. Power supplies, coolers, TPlinks and cables have been standing by for between 2 and 3 months.

We don't have BGA equipment to do anything with the ASICs themselves, but anything pinned surface-mount we can probably handle.

Feel free to PM if you want to discuss anything.

ASICs are other part of the story.
So you'll need to make some small fix diconect of one end of 0805 Cap solder a wire to this end and solder the other end of the wire to other Cap's end.
I'll send you photos .
PM me with e-mail

I mentioned on here a bit ago, and messaged Vesi last week, about potentially doing some of the stateside repairs - specifically for the fifty-odd boards which will end up in our hosting facility. Marto, since you're around at talking, is that something you might consider?

What do you need

I still waiting for technobit to shipped 67 more boards to me. I would really like to transfer ownership to someone else. I'm asking $12,000 for 67 HEX4M boards, that's 26,800GH. Or make an offer I can't refuse. BTC preferred, your choice of escrow. Thank you..

30 pcs went you to you today.
So you can sell them directly

I hooked up my 3e miner today and im having some issue's with it..

it can not run on the default clock and voltage settings. it preforming 20 to 50% less than my other 2 and it cant run on lower clock setting like my other 2 miners can.. ?

Technobit.

I still did not recieve an answer to my problem.
Send you an email a week ago, no reply.. !!

Hi I believe we did write it already.
The diference are minion chips they vary in behavior.
If @ about 400 it is hashing less than 365-370 place a RMA and ship it back we'll exchange it for you

I appreciate Marto's and technobit's intention to provide an open, transparent process. This question should be easy to answer. Could you answer it please?

Hello? How far behind are you guys, exactly? Is there any way to get specific information on our orders?

I was able to fix the issues with my boards. Instead of just thermal paste I used:

Fujipoly / ModRight Ultra Extreme System Builder Thermal Pad Blister Pack - 1/2 Sheet - 200 x 150 x 0.5 - Thermal Conductivity 17.0 W/mK

I cut small squares of the thermal pad, cleaned the paste off the cooler and the chip, and applied the pad material. This made a huge difference in the cooling ability of the fans.

Just an FYI if you are having issues...

Is there a diagnostic procedure for the HEX4M running on the TP-Link devices?

I have several HEX4M boards which are running around 4Gh and I was hoping there was a process for figuring out what is wrong with them.

I remounted the coolers with fresh paste and tried different settings but they still don't behave properly.

what do you mean with huge diffrence?
What changed?

Got my 2HEX4M miners today. Had a problem hooking them up with a mr3020. Cgminer kept saying it was unable to connect. Could be the powered hub I was using. The miners are fine however because I connected to a pc and they hash great. Thanks Marto for building a great miner and no screw job like blackarrow.

After 4 months you should know the answer is no.
