Hmm, so that could be ok, and the 51219 step down chip could be bad? It's a bit beyond me at this stage anyway 

Thanks a lot, I'll let you know how I get on

Edit: Had a reply from Ernst at bitshopper, they're going to replace it for me. (Danke Schoen Ernst!)

Cool, can't wait to get going again 

Hi Sidehack,

First post on the forum, hey everyone!

I bought one of the Gekkoscience sticks from bitshopper.de via amazon (I'm in UK).. It's been great fun, I love tinkering and overclocking so this is my cup of tea! . I ran it for a while just at 150mhz on usb 2.0, then modded a usb extention cable so i had 22awg silicone wire connected directly to the grnd and 12v and supplied by an adjustable power supply set to 5.1V. Ramping it up a bit at a time I ended up with 366mhz on 0.75V with a strong fan blowing on it (1.92A at usb). Awesome! I was going to drill and tap an old cpu heatsink to run it more quietly at that speed but it's stopped working after plugging it into a mates laptop (with voltage set back down and 150mhz).

It's not being recognised any more, vcore is 5-7mV. I *think* it's the CP2102 usb chip, pin 6 should have 3.3v on it and it's outputting the same as the input voltage so I guess the internal regulator is fooked. Nothing looks burnt so do you think the BM1384 would have survived? Is it saveable? I've only had it a few days 

I'm waiting for an email back from bitshopper, hopefully they'll have a look at it for me.. If not, could I send it to you? I'd be happy to reimburse your for your time as it's not one of yours.

Thanks!
