need help with benchmark answers .......................

I did some benchmark tests and I got back some things I dont understand very well...... and they say (sisiandra) to fix them.

My computer first off is a AMD 4800 64x2 dual-core
processor chip. Memory is 2 gigs corsair.

First off it says something about APIC?

It says no APIC found? "all modern mp systems should contain an APIC"?
What is APIC? And how do I fix that? Says check bios settings but not sure.

Also it came up with this below

"The benchmark has tested the primary cpu only" says "You need to turn on multiprocessor option" it says "use windows xp and turn on the multiprocessor kernal"?
what the hell does that mean lol ........

Also says for the chipset I am using that I should use the maximum power for the chip in the bios or something?

ALSO what is the best benchmark program to use is SISIANDRIA THE BEST OR NO? I ALSO USE PCPITSTOP TOO..... And if I did want to overclock my cpu how do i do it? I do have the zalman heatsink on top of my chip ..Is there step by step guide to do this (overclock) or no?

 

Please do not double post.
