RAM? Is it just a male sheep or is there more to it?

    Hi again all,

    Well I have my first machine up and running and all is well-ish.

    I currently have 2gig of ram in it, and I'm gonna upgrade to 8Gig (I'm a heavy VMWare user, and the prices I'm seeing aren't too bad). However, my "haven't built a machine since college, back in the dark ages" n00bishness is showing in this case. So I need some advice on RAM compatibility. So here's the layout.

    CPU: http://www.komplett.ie/k/ki.asp?sku=331906
    Mobo: http://www.komplett.ie/k/ki.asp?sku=322111
    Current RAM: http://www.komplett.ie/k/ki.asp?sku=324460

    Now... I obviously need to go with DDR2 for my new ram. No problem there. I also want 4 * 2G, probably OCZ as from what I've been reading they are pretty decent.

    My question is around the whole PCxxxx and latency side of things. I guess higher numbers are better so DDR2 PC9600 would be best? But does my current mobo support that etc etc. Also, what's the story with the whole CL4-4-4-15 etc etc?

    Any guidance would be greatly appreciated. I'm having fun with this build so far :p

    Cheers,
    B

    That board and CPU don't support RAM speeds past 800MHz, so DDR2-6400 is the highest you should go, unless you intend to overclock it.

    CLX-X-X-X is the timings for the ram you're looking at. The only number you need to worry about is the first one (CL4 in your case). this refers to the number of clock cycles the processor will go through before the ram has the first array of data ready. In your case the processor will do 3clock cycles and on the 4th cycle the ram will have the data ready. The lower the number in this case the better but looking at the latest ram timings, the clock cycles seem to be getting higher, especially with DDR3. But CL4 is a pretty good time.
