I've been reading through this thread and I think vapourminer mentioned that there's no cable included with purchase of the Atmel Dragon. He mentioned cutting down a 40 pin IDE cable but I don't even have such a common thing lying around.
nope no cable included. I did use a 40 conductor IDE cable cut down to 10 (2x5). the cable you linked to should be fine. any 2x5 cable with 0.1 inch pin spacing will work. after 7 hours its average is 8285.56 ghs, 81 hardware errors.  |

I finally got it!
Do I have to open it up to change the PSU voltage settings so that it's 220?
Nope, that wont be necessary. But do open it up and check for loose screws, cables ,etc. |

850 W sounds like a lot for 3 hashing modules @ 350 MHz. This is at 120 V? I am at 230 V and my default Batch #2 units with the 850 W power supply (enermax) pulls 765 W and the units I converted to a SilverStone Technology Strider Gold ST1200-G run at 735 W (92% power factor) yes, 120V. There is a chance that my P3killawatt is off. I will verify with my FLUKE DMM. I upgraded the power supply to a Corsair AX850 and now at 350MHz I'm pulling about 720 watts from the wall. The stock power supply is an Enermax 750 watt gold power supply, but it looks like it can't run very efficiently near it's maximum load and is probably very unstable given the number of hardware errors I was seeing with it at 325 MHz. The Season X-650 is a 650watt power supply, so you may be overloading it and that's why you're seeing 870watts. mistyped 650, actually it's 750W PSU  857 Watts by P3  Room/External Temps + Humidity  |
