Intel's New DDR Chipsets - 845E & 845G

DDR333 - Only for the 845G
Although Intel still hasn't officially embraced DDR333 as a memory standard, motherboards based on the 845G chipset do support the proper multiplier in order to run the memory bus asynchronously at 166MHz for use with DDR333 memory. Obviously Intel's own 845G board won't allow it but the third party solutions out of Taiwan seem to have no problem with enabling DDR333 support. This gives the 845G the ability to compete with VIA's P4X333 on a performance level.
Unfortunately the same cannot be said about the 845E which only adds support for the 533MHz FSB without offering the proper multiplier for DDR333 memory.
We've included this table to help compare the latest Pentium 4 chipsets:
