So... I'm not really a hardware guru or something... Anyway, I have this rather old PC and I want to make some use out of it.
Its motherboard is a GIgabyte GA-8IPE1000 Pro2. The FSB is 800MHz and it can accept 4GB of DDR2-400 RAM (unless Dual Channel is something else?). It already has 512MB of RAM, and I want to buy an additional 2GB. Now... DDR2-400 is supposed to work at 200MHz, but everywhere they sell them it says 400MHz - why is that? If I buy 2GB of DDR2, can I leave this 512 stick inside so the total will be 2560? I don't know the specifications of the 512 stick because I'm running Linux and lshw doesn't list the memory info for some reason - maybe CPU-Z will show when I try Windows later. I guess if they're not the same type (DDR, DDR2) or have the same clock, it wouldn't work? What about if they're the same type and have the same clock, but one is a 2GB stick and the other a 512MB? Also, DDR2-800 wouldn't work either, because my motherboard doesn't support it, right? Thank you!
Edit:
Here is the CPU-Z output
So I guess it's a DDR-333 (160MHz)?
