“why only 800Mhz? I believe it’s a chipset limitation when all memory slots are filled”

With Nehalem EP you can only have 1 DIMM per slot at 1333, 2 clocks down to 1066 and 3 down to 800. Westmere EP support 2 DIMMs at 1333 as well as low-voltage DIMS.

“why only 800Mhz? I believe it’s a chipset limitation when all memory slots are filled”

It’s a CPU thing (since memory controller is located on the CPU uncore, not the chipset) which depends on how many modules you have per channel. More than 2 modules per channel will put you at 800 if you follow Intel’s spec.
