Okay a Bunch of really ugly quoting occurred so I've re-formatted for
clarity.
I am currently running a P4 1.6GHz and would like to upgrade to the
3.2GHz.
I also have 4GB PC2100DDR, which I am not interested in changing. Can
I replace the 1.6 with the 3.2 without changing anything else?
Yes, the P4C800-E will handle both all 3 incarnations of the P4 3.2
(C, EE and E)
And you can install all 4 1GB Modules of PC2100/DDR266

As far as I know, the P4 3.2GHz CPUs run on a 200 MHz FSB only....That
would require PC3200 DDR. Your motherboard would have to support
Northwood/Prescott CPUs as well.
Running a 800FSB to the best of my experience doesnt REQUIRE you to run
DDR400/PC3200 RAM, It is just recommended to get a stock 1:1 FSB:RAM ratio.
There are two other FSB-to-RAM-speed ratios available - 5:4 and 3:2. At
stock speed, 5:4 means the FSB will be 200MHz and the RAM speed will be
160MHz; 3:2 gives a RAM speed of 133MHz.
Although when using a 800 FSB processor, PC2700 (DDR333 memory) is
actually adressed at 320Mhz, this is normal for the chipset.
As for motherboard support, yes the P4C800-E was built to the
specifications required for Prescott CPU's so he's got a upgrade path as
well.
