ASUS P4B266 Mobo BIOS CPU frequency and multiple settings question

[Peabody]

I have an ASUS P4B266 mobo in a system that just decided to reboot itself to the CPU BIOS setup. The CPU is a P4 1800 MHz. I want to make sure that it is set correctly before saving and exiting BIOS. It is currently set for 1800 MHz with a multiple of 18 and the bus speed of 100. I read the mobo manual but it was not clear to me. Could someone please tell me what to set the CPU settings on for normal running at 1800 MHz? Thanks

Well, you won't be able to change the multiplier ("18") anyway. The FSB ("100") is now set at it's default speed. Works like this: 18 x 100 = 1800Mhz.

So if you're OCing it goes like this (for instance) 18 x 120 = 2160Mhz, 18 x 133 = 2394Mhz, etc.

Thanks for your post. Isn't 100 fsb speed low for the P4 mobo? I thought it should be 133 or 266 even, but can not figure out what multiplier to use. I don't want to OC, I just want to set it to its normal settings. Thanks again

You are fine, The P4's have a quad pumped fsb which is 400mhz (4X100).
In spec you should be 18X100.
