Need Advanced Advice

[forgettythatty]

I have an Athalon xp1800
+ and a super koolance case, pc2100 crucial ram, and a k7t266 pro-ru mobo (http://msicomputer.com/product/detail_spec/K7T266_Pro.htm).

Now here is where I need advice:

I want to overclock, but I read here:

http://accelenation.com/?doc=86

if you overclock and you have pci/agp cards they won't work because your motherboard doesn't have the right dividers. Anybody know about this?

Also would it be worth it to sell the motherboard I have (it is still in box) and get a K7T266 Pro2? would the performance really be that different? and would that have the overclocking problem too? Will nforce be able to be overclocked? It seems there is no overclocking solution until this board comes out:

And does anybody know of a good site tellin you how to overclock the athlonxp, because its bridges are laser cut.

depends, what fsb are you running? at 100 the pci will be running at 1/3 (33) at 133 the pci will still be at 33 (1/4) any higher than 133, unless your mobo has a 1/5 multilier then the pci/agp busses will be running out of spec, sometimes a prob, sometimes not..

MOst cards will handle up to 166MHz FSB as long as your processor and memory can. You only need 156MHz to get past 1800MHz, roughly the limmit for that processor. You may need to lower your memory timing to get that high, or use PC2400 or PC2700.

Back to you Tom...

well, any overclocking streses other components in the system that arent directly related.

all you should keep in mind is that the PCI bus should not go above 40, it works fine at 37 but may be doddgy above it, so the best bet is PCI = 37 MHz, that gives 148 MHz of max FSB with a common divider of 4. If you go past it you might need a divider of 5 which is available only in some recent boards. AGP uses twice the PCI clock.

another thing to watch out for is the core voltages.
