New ram chips, what settings to use?

I've just installed two new 512MB (Crucial) DDR pc3200 ram chips to one
of my pc's. They are working fine at the moment.

This pc used to have 2 x 256mb DDR pc2700 ram chips before this.

The pc in question is an AMD Barton 2500+ cpu on an Asus A7n8x DELUXE
M/B (Rev2).

With the old 256mb ram chips installed the pc was being run using 175FSB
and a muliptlier of 12 giving a cpu speed of 2.1Ghz (175 x 12 == 2100).

Now that I have the higher (pc3200) rated ram chips can I change the FSB
to 200?

NB:Apparently this motherboard does support 200 (eg: DDR @ 400) if it is
the Rev2 version (which mine is).

If I change the FSB to 200 I will have to reduce the multiplier
presumably or else the cpu will be running too fast (200 x 12 = 2400) I
therefore presume running at 10.5 x 200 (= 2.1Ghz) should work ok?

FSB 200 should work with no problems
and yes, use 10.5 X 200

if for any reason the machine does not post...
all you'd have to do is reset the bios
(there is usually a jumper to do so)
but it's not likely there will be any trouble

Thanx for the info...
