Uhm. Well, the motherboard specs state it's designed for 800Mhz and 667Mhz memory. The memory you propose is 533Mhz, so there's a chance it won't be compatible.
However, it's often the case that slower memory will work even when it's not specifically supported. It all depends on your BIOS settings, and also on what kind of memory is already present.
: I reviewed your motherboard's manual, and this came out:
So it seems 533Mhz is
supported after all. The RAM stick you proposed should work.
Do keep in mind that if you install RAM modules rated at different speeds, they will run at the speed of the slowest one.
