Athlon XP 1800... PC2100?

I have an XP1800 system running on a Abit KR7a-133. I'm looking to upgrade the RAM, and I see that crucial says my board supports up to PC3200. There is currently a 512mb stick of PC2100 in there, and I'm planning on doubling it. Will I get any performance benefit from getting memory faster than PC2100, or will it be no difference with my processor?
 
there'll be no difference

but buy PC3200 anyway as u can use it indefinately when you do your next major upgrade. all that will happen, by putting another stick of 512 PC3200 iin your rig, is it will run the same speed as the pc2100

if it doesnt make sure it does, it makes sense to buy 3200 now and just run it at 2100 speeds so it matches your current memory. but you will see a difference in performance....not so much speed increase, just that everything will be smoother in operation, as you'll be swapping files off the HD less

Yeah I'm upgrading to get rid of the HD load lag in WOW. So putting 3200 in there next to a 2100 wont cause any problems?
 
what you will want to do is go into bios and lower the PC3200 ram to PC2100 speeds, then make the latencies match that of your PC2100 ram - usually possible.

PC3200 can increase your performance greatly if you are willing to overclock your 1800+ assuming it is a tbred not palomino, to 200fsb. You will have to increase Core voltage, and lower the multiplier a little bit.

Right now I have my 1800+ running at 200mhz fsb with 11 multiplier @ 1.75V (up from 1.5V)

yeah he's right

just get a stick of 3200, value ram, try hit for a CAS of 2.5 rather than 3, but when u get it in your system jus go in to the bios and go to something like advance chipset features or something, just make sure that both sticks are running at the same speed and have the same timings.

then once in windows you can check that you did it right with programs such as CPU-Z and Everest.

as for Overclocking, if you have a palomino core'd XP (CPU-Z will tell u this) then you'll be lucky to get 1.8Ghz from it.
