Seems like this forum is dead, but I have a problem guys, and I hope someone will surface to help me out. I have this motherboard coupled with an AMD 64 3400+. Ive been running it with 512 MB of Patriot extreme performance DDR400(3200) RAM. However, I decided to upgrade and bought another 512 MB stick of the exact same RAM. Well problems began from there. Both sticks work in each DIMM slot so I know there are no defects on either sticks of RAM nor the slots. Unfortunately, the two sticks do not work together. I get a RAM error beep when I startup, preventing bootup. I reset BIOS to optimal settings and still no bootup with both sticks of RAM. I wonder if this is a known problem and if so, or not, someone here can provide some suggestions. I will greatly appreciate it. Thanks
