You see, I've had this problem from day 1. So I never got around to changing my memory settings from defaults. :shadedshu Defaults are 1066 MHz, 1.5x v, 8-8-8-xx. I figured since it can do 1600 MHz 8-8-8-xx at 1.65v, then it can do 1066, same timings at 1.5v. I can try to bump up the voltage... but right now this thing barely lets me in the bios. My ram passed memtest a few months ago. I cant get this thing to boot anything so I can't run it now. So bad ram is a possibility. I took the mobo out of the case and guess what? Found an unused standoff. (no hole in the mobo where the standoff was) Took that out. Booted up. And then it shut down. I figure that if it's a short, it would either not turn on, or turn off immediately. The fact that it runs ok Regarding the weird memory recognition issue, I was able to get this. It shows yet another memory config. The sticks may be in a different order, but they're in the same slots. ?? Computer is being extremely uncooperative. Thing won't even boot anymore. Might need to wait longer when I unplug the PSU in between shutdowns. When it does boot, I can't get more than 3 min out of it. And it's been pretty consistent, which is unusual. Here's what I have so far, will edit if the computer boots. yellow - 12.24v red - 5.11v purple - 3.28v (PSU was plugged in, computer off) No fluxuations outside of a few .01v that I can see with my MM. I should also add that I contacted Silverstone Support a few days ago and told them I'm still having issues. Broken english is vague, but I'm going to assume that my PSU was tested with whatever they test PSUs with. They sent the same unit back to me, confirmed by serial number. So Silverstone is saying the PSU is good.
