I'm busy with hex8a1 @ the moment
If they refuse insurance I'll ship anyway replacement power in wednesday

I've tried in the past to run cgminer on windows - it actually compiles just fine, but not working. The problem is with the communication with the board and usb interface driver, with bfgminer it might be easier, but I gave up on that. We even had a bounty for windows version but without success.

Thanks but I would like cgminer or bfgminer. If I run this Hexminer I get memory problems... I didn't test it on a HEX8a since it still didn't arrive(don't ask what speedy did but I wasn't worried for nothing when I was asking what is going on) but I do have problems with HEX16a. I do have 4 TP-Link TL-3020 ready for my 11 boards just in case but would also like to have a reliable windows option.

That is why I'm asking...
Mato would you by any chance compile a windows cgminer... I can't figure it out how to do it... Follow the instructions but it looks like I'm missing something...
https://github.com/ckolivas/cgminer/blob/master/windows-build.txt
Step * Install mingw32
I think I do something wrong hire since I'm missing
Start Icon/keyboard key ==> All Programs ==> MinGW ==> MinGW Shell
in next step... I think instructions are too old and MinGW is now different...

Try this old video tutorial... http://www.youtube.com/watch?v=l9SgoVm16Sw You need a proxy for it to work in windows.
Seriously though use a TP-Link TL-3020 it saves you loads of power don't bother running anything on a PC!

Marto is this safe setting? This is what you run your test board on...
Who can say. It depends how hot the environment it's in gets. Give it plenty of cold air.
Temp is not a problem. I put server rack on a balcony and a good fans in it. So it will top at about 15C...

With 200/900 speed/voltage, after 8.7 hours, 11635 nonces @ 128 difficulty, 204.2GH/s average speed, zero hardware errors
Restarting with 210/900
Restarting with 210/900
@900mV you can go upto 240 freq on some boards
14986 nonces @ 128 difficulty
6 hardware errors
216.169 GH/s
And my other WR-703N is playing silly buggers and not starting cgminer by itself, having to resort to putty. Admittedly that specific WR-703N and release 0.1.0 on it which I upgraded to 0.2.0 with the factory bin file, and kept the settings....
That was really nice result, my board can not run stable like that.

Sounds like a good board I get nowhere near 204GH at 200/900, more like 185-195GH!
I'm currently running 220/910 for 220GH 0.3% error, on a good day, with 3x Arctic F9 quiet fans.

Marto did say he was moving to a better way of handling it, instead of poly-fuses, you must have one of the latest boards.
So my question to marto is still opened
I'd be very greatful if you could give us a power/GH reading from your new board. I suspect poly-fuses weren't very power efficiency friendly.
Sure.
Over the past 16 hours, the board hashed at an average of 221.5 Ghs configured with 240@900mV
The power consumption is very stable at 283 W which means 1.28 W/GHs (with a very low 0.12 % hardware error ratio)
I'll probably make some tests with different settings but I'm not at home for the next week and I prefer to be not far from a board while testing new parameters
Let me know if you'd like me to focus on specific clock/power couples.Again and as far as I'm concerned, these boards are just awesome !
Delivered right in time, with a fair & right price, I would have bought more if I had not thousands of $$$ in BlackArrow's bank account, waiting for an again delayed delivery...

Thanks, I was hoping without the poly-fuses they would run better, but it seems about the same as the one I have where all the poly-fuse legs are attached. Of course you won't have to worry about knocking legs off with your board, which does seem to impact performance.

@marto
I was wondering if your A1 based board implements a sort of emergency shutdown ?
The use case might be when the board is going too hot, because of an internal issue or because of a fan running slowly for instance.
If not, that would be a good feature (together with regulated fan speed) to implement in the next generation

If your board has poly-fuses on, it has that, that's what those ugly yellow/orange/brown tags do.
Not sure I have this components onboard (if you're talking about the same yellow things we saw a couple of posts before).
I don't know a lot about electronic but how does that works exactly ?
Here is a picture of my board :
