I have an Abit NF7-S motherboard that I bought when it first came out and have been running an Athlon 1GHz and DDR266 memory on it. I am upgrading it to an Athlon XP 3000+ 400FSB and upgrading the memory with two Kingston HyperX PC3500 256MB chips for dual DDR.
My question is what do I run everything at to get that 1:1 ratio that is recommended? Do I overclock the FSB to 217MHz which at x2 will match the memory? Or do I run the memory at PC3200 speeds, which I have no idea how to do that? Or do I have no idea what I am saying.
 
Run the memory at PC3200 for best stability. If you're overclocking.....it's up to you.

So how do I do that? I just found out that my motherboard only supports up to 333MHz FSB (NF7-S v1.0). So am I better off replacing the memory with PC2700 memory to get that 1:1 ratio or can I run my PC3500 memory at DDR333 speed? If I should keep my PC3500 memory, how do I run it at the correct speed?

Keep in mind that the rated speed of the memory module is how fast it can be ran. If you put some 3200 memory on a motherboard with DDr333(2700), the memory will run at 2700. In that case it would be underclock...So you can pump your front side bus to 200mhz. Like this your memory and processor will do fine, only the motherboard will be overclocked.
 
Two plusses of running PC3500 at PC3200 speeds will be the heat will be less and the stability will be excellent.

less heat...i doubt it...since the memory modules used in 3500 are most likely the same as those used in 3200 there will be a very small diffrence in the heat generated between pc3200 and 3500 running at 3200 speeds...they all use the same chips just some run better than others...just like with cpus...they all have the same core...just some run better

stability...i will let that one go...but really your ram should be super stable at stock speeds...but then again there is alot of $hitty ram out there...

There is no smell better than fried silicon :evil:

I think you should buy a new board with FSB400, both your CPU and your new memory support an FSB of 400, just your board doesn't and since it's usualy the cheapest component of all three you should replace it.

Coppermine, Banias, Opteron, Prescott, Barton... How 'bout investing less in the CPU and more in its name?
