I have P5RD2VM motherboard and Intel Pentium D CPU 2.80GHz. I am currently using 512MB 533 Mhz ram but whenever I try to use 1 GB 667 Mhz ram there is no display, no beep sound. But fan is spinning.There is no trouble when I use 512MB 533 Mhz ram. My motherboard manual says it supports 667 & 533 both. Now in my local market no one is selling 533 ram. So it will be a great help for me if anyone offer me some solution of this problem.
