Erlik the ram i have are both 512 ddr. now one is pc3200 and the other is ddr 400mhz. I was informed when i bought the pc3200 ram that it was 400mhz as well.. After looking at the sticker on the sencong lot of ram it has NPC N7773 DDR512 PC3200 on it and that is all so i took it to be correct because it was from a shop and the tech guy told me it was 400mhz.

I have opinions of my own -- strong opinions -- but I don't always agree with them.
