I'm finding I need to upgrade my RAM soon, I've currently got 2 512mb modules and 4 slots to fill up, each can take 1gb, and pentium 4 with ht. However I've had difficulty identifying what I need to get, I've used the Crucial System Scan and it told me I needed DDR, PC3200 and DIMM module (here). To be honest I dont know a lot about what I need, or what I could use.
I also used CPU-Z and I've taken a few screenshots of what it has said;
After checking that out, It said that my RAM was 200mhz, so I was wondering if I could use something with 400mhz like this? It also said it was unbuffered, what does this mean and could I use a module which is buffered? Also would I notice the difference with a 400mhz module, assuming it will fit.
Another thing which I have realised after researching the motherboard on intel, it said the computer could take DDR2 modules, but I thought that DDR2 was a different size to DDR, so how can it take DDR2?
I would really appreciate it if someone could explain this and point me in the right direction.
