With your 845E chipset you can support PC1600 (200) or PC 2100 (266).
PC2100 is a better match for your chipset out of the 2 because it's in step
with your true front side bus. You will not be able to use the higher bandwidth
of the pc2700 (333) and it is not in step with your board which means latency(lag).
The pc2700 will simply function as a pc2100 on your board.
Intel claims a 533/400 front side but it is only possible on this chipset between
the cpu & chipset. Between cpu & ram it's only 266/200 depending on the ram you
choose. Between ram & chipset we're still at 266/200. True front side bus speed is
the speed between your cpu-ram-chipset.
The rambus or rimm based boards are the only ones that can utilize the full
533/400 front side bus. The 850e is an example chipset for that. P4's & Rimms
both implement 4 data transfers/clock cycle to yield (133 x 4=533 or 100x4=400)

This is my situation. I'm trying to build my own computer. The motherboard
I have selected is ASUS P4B533-E.
This is some of the info I've taken from the spec sheet;
CPU-Socket 478 for Intel Pentium 4, 512/256KB L2
Cache.
Chipset-Intel 82845E MCH, 82801 DB ICH4
Enhanced 533MHz Front-Side-Bus
Front Side Bus--533/400 MHz
Memory--3 x 184-pin DIMM Sockets support max 2GB PC2100/PC1600
ECC/non-ECC DDR SDRAM memory.
The reason I am asking these questions is because Crucial's price sheet
says that the PC2100 & PC2700 are compatible with this mobo (ASUS P4B533-E).
The PC2700 may be compatible, but does it improve anything. I certainly
don't want the PC2700 if it doesn't.
