</div></div>I've tried 4 different sticks of RAM with the same outcome, the first<br>
pair was "Kingston ValueRAM 2GB (1GB x 2) 800MHz DDR2 Non-ECC CL5<br>
Unbuffered DIMM (Kit of 2)", the second is "A-Data DDR2 800 240pin 2GB<br>
Kit (2x1GB) Unbuffered-DIMM Non-ECC Memory (w/ Heatsink)", I can't<br>
believe they are all bad, so it seems the only other issue could be<br>
the power supply or the board itself. I've tried two different power<br>
supplies with the same results as well, I can only point my finger at<br>
the board itself. It's a shame, since I was really excited to try this<br>
thing out!<br>
<br>
Thanks for all the suggestions. I have contacted both the vendor and<br>
the manufacturer, I don't expect to hear anything before EOD Monday<br>
from them, though.<br>
