    Which AMD cpu to work with this new mobo and old ram?

    Hi guy,

    I’m *trying * to buy and build a computer for a friend. I have the ‘Abit NF7-S’ mobo and he already has about a gig of DDR 2100 ram. So I want the best CPU to fit in with mobo, but I’m a little confused on weather the RAM will will work with the cpu. So looking for a AMD 3000 chip… which one from aria.co.uk ? where I’m about to order some other stuff from

    Well if you order a non mobile chip you are limited to tbreds as bartons use 166fsb, you could order a 2500m from cpucity and use 133fsb (go crazy with multi and you will probably get 3200+ speeds).

    ok sorry guys, please bare with me, i have limited knowledge!

    So the maxim cpu i can get in there with that current ram is an XP 2500 mobile running at no more that 133 fsb?

    Would i be correct in that statement?

    You can get any CPU you want, and run it at it's full speed. But to get maximum performance you should really run the CPU and RAM at the same speed (1:1 ratio).

    Go for a 3000+ (333FSB) if he really wants it, it'll run at 13*166MHz or the 3000+ (400FSB) will run at 10.5*200MHz. But his memory will only run at 133MHz, perhaps a little more with a bit more juice and a little overclock.

    Actually, it will be better going for the more powerful chip, as later he'll only have to upgrade his RAM (to PC3200 at least) to get a massive increase in performance.

    I'd go for the 400FSB version. It's actually CHEAPER! That's supply and demand for you!

    :edit: Have to add though, personally, I would get a mobile chip... oh, I did!

    No, he can run the CPU at 200MHz, and the RAM at 133MHz, it just won't be as fast as running them both at 200MHz.

    If you run the XP3000+ at 133MHz, it'll only run at 1.4GHz.

    Depending on motherboard bios options of course, not all amd mobo's have the ability to run fsb/ram out of sync.

    The NF7-S can, that's the board he's getting.

    Go with the best cpu - 200fsb - you can always upgrade the ram later. In bios just set the cpu/ram ratio to 6/4. You'll obviously get less bandwidth due to them not being in sync but at least you're in a better position to upgrade one stage at a time.

    Don't know if youre still looking at buying from Aria but their generic ram isn't bad at all. Decent stuff and even worked dual channel in my NF7S. Theres not a huge difference between the price he can sell the gb of 2100 for on fleabay and the price of a gb of 3200 on aria.

    Edit: bugger, should have read your other thread.
