I'm having zero luck getting this thing to work for longer than 10 minutes. I've followed the thorough setup guide here and the one on technobits site. No matter what changes I make to cgminer's config file the miner goes dead within 10 minutes or so. I've tried other pc's, different usb ports, different cables, powered hubs, non powered hubs, nothing....

Anyone here have one working in cgminer mind posting their config files text?

Thanks!

What is your setting on config file?
Try using TPLINK TL-MR3020 as a host. Check if the heatsink touch the chips correctly.

I'll post the config file's text when I get to the miner later today. I was thinking about using a TPLink device but I dont have one handy. I'd hate to throw money at this thing if its just going to be a PITA.

There are two config file that I'm using. This first one ends up with the "last received nonce 2 seconds ago" lines over and over again and never mines. This is the config file that comes with this modified version of cgminer.

This next config file is created by the same version of cgminer but will only mine for about 10 minutes. It will eventually crap out and say the miner is dead. By created I mean I delete the cgminer.conf file, start cgminer, enter my pool and user info and have cgminer write the config file.

I found a version of cgminer called "dice version" (I think its on technobits website). It seems to be capable of detecting when the miner gets below a gh's threshold and it resets itself.

So far in the last hour or so its reset itself and the miner 18 times.

Heh.. It just reset again.

Try these setting:

Thanks for the pointers! I'll give this a shot tomorrow.

So the miner has had to be reset 202 times today. Fun stuff... :(

That can be reduced from these setting:
"hexminerm-nonce-timeout-secs" : "20", put bigger value
"hexminerm-reset-below-threshold" : "10", ==> put smaller value
"hexminerm-reset-wait" : "600", put bigger value

@Zich.

I tried your suggestions and the same thing happened. Miner worked for about 10 minutes, went sick, went zombie went dead. For now I'm using the config that resets cgminer when the hashing falls below 50ghs so its fine.

I never have any luck with TechnoBit's stuff. I probably should have avoided this miner too.

What is your psu brand & type?

1300 watt EVGA Gold.

I also tried a Corsair HX750 I had sitting around and the miner behaved the same way.

That's all good psu. Maybe you want to check the heatsink. See if the heatsink touch the chips or not.
And give some load on +5V rail. Some psu need load there.

Heatsink seems OK but I'll look at that tomorrow. I've got a 20 watt metal resistor I can put across the +5.

Old cdrom drive will do the trick  :)

Heatsinks were fine and putting a load on the +5 didnt change the operation of the miner. Still failed after 10-15 minutes.

Try to lower the clock

or


If still fail, please pm marto (https://bitcointalk.org/index.php?action=pm;sa=send;u=84195). He will help you using teamviewer.

Thanks. I'm traveling so I dont want to mess with what seems to be working right now. After some fooling around I've had to hard reset the miner and cant do that from where I am at the moment.

Does Marto work for Technobit? I'd hate to bother the guy otherwise.

Marto is the owner  :)
This is as far i can help you since i don't own hex4m  :D
I had hex16a, hex16c & hex8. Software setting is similar, but the led indicator is different. So marto can explain more  :)
