Overclocking ratios in the bios

I was just wondering when I am overclocking and in my bios

I always leave my AGP voltage alone----Is this correct...should I change it...if so would it hurt...increase performance...etc.

Next the n/b strap ratio...I have pc 3200 ram...so do i leave it on default of change it to psb 400?...what does the n/b strap ratio control.

Next the DRAM ratio...I run pc 3200 RAM with a cpu with a 133mhz fsb...I have it overclocked where my RAM frequency is about 195mhz using a 4:5 ratio....Now...can i use a different ratio and try things out....like 1:1 or 2:3...how would this affect things.

Lastly, my AGP ratio is always fixed at 33/66....why...and what happens if i would change that.
 
i'm too lazy to answer the other ?'s, but if you mess with the agp/pci lock settings, you risk frying your video cards and any cards you have in the PCI slots

there is no need to adjust the AGP voltage, it won't make it any more stable on an OC. Unless you have high quality low latency PC3200 you should run your divider at 5:4 (320mHz) for the best possible OC with a 800FSB proc. Always keep your AGP/PCI locked to the native 66/33 due to the buses don't like being OC'd...especially finiky sound cards...

:edit:: your 2.4's native bus runs @ 533, then you should be in a divider of 1:1(133mhz) cause your RAM wont ever be maxed out past 200FSB...that will help you find your CPU's max OC w/o having your ram's limitations in the picture. Once eyou find your CPU's max OC, then go back to 4:5 and see how high you can get, with the faster RAM bus. Post the results for us...:cool:
