Topic: Avalon2 based miner from Technobit - HEX16A2 - page 2. (Read 33473 times)

Hi, i use always standard configuration, --hexminerc-voltage 1100 --hexminerc-options 16:1500 --set_default_to_c , can I use Arctic F9 with this setting?

Thanks Luca

If you run it at 1400/1040mV - 21GH/s or lower settings lets say 1300/1000 you can put Arctic F9 Standart:

Hi, the fan of my HEX16A2 has some problem, so i need to replace it, can you suggest me what kind of fun i have to buy?

Thanks in advance Luca

There is git checkout command that will make sure you are at right version. if you follow the step by step, there should be no problem.
What is the error message? Maybe one of dependencies is not installed.



New patch already publish by marto but for cgminer-4.0.0

Zich, this consistently fails for me, and it suddenly occured to me that the cgminer git is now at 4.0.1 - Is there a patch for 4.0.1 or should I try to load the 3.12.3 from an archive?

You are welcome 

Thanks Zich 

Don't forget to apply patch before compile  

To compile cgminer-api, on cgminer folder run command:

Then add api allow & api listen to cgminer.conf

You can run it on compiled cgminer foder with command:

Or you can copy cgminer-api to /usr/bin so you can run "cgminer-api stats" anywhere   & without using ./

 I am waiting my new HEX16A2 , now i have assembled a reinforced molex with 2 cables for each pin, i hope that it can deliver all the current necessary for the miner without burning.
Can someone explain how compile cgminer-api, i have compiled with only the options

are requested others options?

Thanks in advance Luca

If you got lower hash rate at 1100/1500, then i suspect that your miner had dead chip
You can check by running ./cgminer-api stats command under cgminer ofc. You need to compile cgminer-api first  

Just picked up one of these miners recently. thanks for this post, and the link to the older tutorial for setting up HEX miner using the proxy. I was having a bit of trouble setting it up.

I got some different results than that of the OP when upping voltage. I noticed better hashrate by keeping voltage generally lower (1.200v-1.35v) and clocking the ship to somewhere around 1540-1580 MH/s. My current settings are 1560 MH/s @ 1.350v. This gives me ~22.3 GH/s, and my voltage never tends to top out over 1.220v. It runs a bit on the warm side, but I'd expect it to do so. Running under 1500 MH/s @ 1.200v-1.300v lefter me with a hashrate under 20 GH/s.

Unfortunately, I don't have the tools or knowhow to test heat, and it seems that these do not have a sensor. Although it was advertised at 24+GH/s, that is indeed misleading. You have to run it pretty hot to get 24-25 GH/s, and I'm not sure it's worth it. My current settings leave me with a warm miner, but it's nothing like a couple BFL 10 GH/s units I own that would reach as high as 82C before I began running them without part of the shell, and even had to take one apart to adjust the tension of heatsink, since the way it was put together had warped the PCB, leaving partial gaps between one of the ships and the sink. Now that one never goes above 72C. I don't think this HEX16A2 is getting near that kind of heat.

For the price I gave (at the time equaled ~$150 USD, and I had no cash, only BTC), I think I got a fine deal. Buying gone new for over 220 Euro seems pricey, but if they push them out the door within 48 hrs, and it may be not so bad of a decision. I'm pleased with my little unit, and if I can find a second one for a similar price, I may well ad another and see if I can figure out enough of Linux to run them on a Raspberry PI or something similar.

As for using CGminer, even with the patch, I couldn't get it to work properly. Not sure what I was doing wrong, and I don't have enough skills to get into the nuts and bolts to try to sort out problems myself. After watching the tutorial on how to use HEX miner, that was good enough for me. I think if you mainly have 55 nm tech, you'll be pleased with the lower power consumption this has compared to any BFL units you might be using. Compared with 28 nm products, well, there isn't really any. My KnC Mercury runs at around 143 GH/s, and pulls ~139W from the wall, so less than 1W per GH/s

I'm not happy with hex miner and would appreciate a hint on how to compile cgminer under windows

Hmm.. maybe it's my miner, then... I get no lights on the bottom, although the fan runs. Hexminer >seems< to detect it as COM PORT 41, but I get no work out of it...

I have a diode (I think) from the 12V molex pin to pin 2 and  pin 3 (if 12v is pin 1)... I don't see that in any of the pictures online. is this a revision, or ...?

EDIT: OK, got the miner to work with hexminer under windows - Kind of sloppy, IMHO. Now I just need to figure out how to get cgminer to compile, and I'll be a happy camper.

There is no cgminer with HEX support for windows, you need linux box.

I believe the stratum proxy is included in the package, there is a link to a video how-to in the OP

Has anyone managed to get a hexminer to work with cgminer 4.0.1? Do I need to compile against 3.8.5?

Also, is there a new proxy for stratum for hexminer? I've got a HEX16A2 that I have not been able to use because I can't get anything to run it and it is killing me!

at higher speeds it can draw over 100W. Molex cables are usually designed for 60W. IMO its not a good idea running these off a cheap/thin cable because it WILL burn through.

I had a chinese 6pin pci extension that was marked 18AWG on all the wires but burst into flames within 5 minutes of being used to carry 180W for an antminer. make sure your wires are thick

It was molex and it melted the second I powered it on. I quick pulled the power. Lots of smoke.  .

Is your board with molex or terminal connection !?

Did it burned right away or after some time, maybe something is shorted ?!

I got one of these today. I plugged in the power and turned on my computer and the power cable going into it melted. Is my PSU the issue?

Form FactorATX
Wattage750W
Modular CablingNo
Fan120 mm
Input Voltage100 ~ 240 VAC

It was the only thing plugged into the cable tree. I do have 4 other drives being powered but from different cables.

Dude, read my post again hexmineru or use stock cgminer it is up to you
