Excellent! I knew there had to be a further hardware mod 'jumper' to get stable operation at 1.25V without converting over to a different mining program. I'm using cpuminer and am quite satisfied with it since I have a very small farm anyway.
One thing that still bugs me though is having to reset the USB ports every 24+/- hours.
Anyway, I can make the jumper mods easily as I own a professional Weller soldering station with adjustable temp, very fine tip assortment, de-soldering etc. So no problems making the mods.
I wonder though, have either of you chaps tried seeing if any of the existing header's pins correspond to either of those two jumper points? Or is that header simply a serial port connection. I haven't studied the schematic yet so I realize this may be a stupid question.
Anyway, I'm very interested in this mod for my own miners. Having done years of laboratory level R&D in electronics, this stuff is a piece of cake!
Have the two jumpers stabilized the GS units well enough to overclock above 950 yet?
Man, if we can get these little buggers running at 500KH/s, that would be fantastic!
But, 400KH/s ain't nothin to laugh at either
I have all my units fanless now. If necessary, I can simply use 1 or 2 fans to blow air on the fins indirectly which will of course keep them running cooler.
I might be interested in making this mod for others too if the money is right.
They'd be responsible for all shipping costs and insurance etc. etc.
I'll figure out what is a fair price to charge per mod later if anyone shows interest.
Thanks for coming up with this mod. Sure saved me some time and hassle.

If you run Windows, you can use the batch file and information I posted here to avoid unplugging/plugging the USB cable every 24 hours. It basically automates the task for you. I don't know if this can be done with *nix, I have no experience with that.One thing that still bugs me though is having to reset the USB ports every 24+/- hours.

Yo V,
what is "*nix"? You mean Unix?
I'm running cpuminer in Windows 7 32 bit.
Will your bat's work with this config?
I'm not keen at all having to covert over to cgminer until I have 20+ miners running but, hopefully cpuminer will have been upgraded sufficiently to handle this number of units too.
Thanks!

I haven't tested the batch file with cpuminer because I use CGminer. However, it should behave exactly the same. If you have a few spare minutes you could try it out. It's quick and easy to test.
