Help with P4 bus and memory speed

[jameswenn]

I have a p4 2.26 533 FSB processor. The processor is only running at 1.7Ghz since the motherboard, intel 850, that it is on will only support 400mhz FSB.

If I place the switch to a board with 533 FSB support, will the processor run at 2.26 or will the fact that the RDRAM runs at 400, bring the processor back to 1.7Ghz?

Thanks

This page indicates it can use either 400 or 533 with the PC800 memory:

But which board of the Intel 850 bunch do you have? There's 5 listed here:

Here's a tidbit about USB on 3 of the 850 boards:

The CPU clock multiplier will likely have to be adjusted in the BIOS.

On a 133MHz FSB (133 x 4 = 533), the Intel CPU you have is expecting a multiplier of 17 (133 x 17 = 2260).

However since your FSB is only at 100MHz (100 x 4 = 400), you'll need a multiplier of at least 22 to get close to the rated speed.
