Memory problem with GA8IPE1000 rev1.0

Hello, I just bought two pc3200 512MB ram modules, OCZ4001024ELDCTE-K. I
have a gigabyte GA-8IPE1000 rev1 motherboard.

The problem I have is, no matter what BIOS settings I use, when I put the
OCZ memory sticks the system does not boot. Either by themselves or with my
current 2x256 sticks thay seem to fail. When on their own, these OCZ sticks
make power led on case rapidly blink and stay like that. When used along
with my older memory sticks, system boots up to Windows startup screen, then
crashes and restarts.

I have F12 BIOS version. Is there anything you know I can do? Thanks a lot.

Carlos.

P.D.--> Already tried to change voltage and refresh settings at BIOS.
