CPU and Memory Speeds Relationship

[zstopa]

Greetings,

Ok, I have a A7N8X Asus mobo with an Athlon XP 2200 processor (1.8ghz).

In my bios, I have the options to change the cpu external frequency to 100, 133, 166, or 200 mhz.

I also have a 512 stick of pc 2100 (266) and a 512 stick of pc 2700 (333).

Should my bios be changed to a particular setting to get the best results? When I added the second stick (2700), my computer seemed to lag hard.

This stuff is prolly basic to you guys but I don't know what my settings should be for best performance...thank you dearly.

Set your external frequentcy to 133 to match your memory speed.

thx

U might also be able to overclock it, though I am not sure you will get better per4mance.

Yeah the reason you got that lag is more than likely because you had an extreme bottleneck in your system from having a CPU with a certain FSB mixed with two different rates of RAM, I just got my PC2700 RAM up from 166 last night to 200 so yeah....got my PC2700 running at PC3200 speeds at 2.5-3-3-6 and it's just samsung generic RAM lol, but it's holding out like a freakin champ...the other stick I have in there is PC3200 but it's rated at 3-3-3-8 so it's pretty crazy it's holding 2.5-3-3-6

hey, thanks for the reply, but what exactly is your recomendation?

Well what kind of stick of RAM is it and do you know it's stock timings? That'll give us a better idea of the quality of stick you're working with

u have 2 put ur CPU ext Freq on 133 ..it is the standard 4 this cpu cos the 2200 AMD freq is 266..
when u put 2 RAM sticks with differant freq ... they will work with the lower 1 ...& u can run the 333 if the 2 sticks r 333 ...
