Yes it can as that mb is ddr2 compatible with any 240pin module motherboards. YOu cannot use any motherboards that utilize ddr or ddr3 as they have a different RAM connector/PIN. DDR2 motherboards are still common and are the norm, they were introduced in late 2004 - early 2005.
so i thought i would update my update. so yep 800 mhz ram works no problem with the 955 BE processor, but the even cooler thing is i was able to boost my ram to 1066 mhz in my motherboards bios...
