Looks Like I am the First one

So here's my Query
Can My MoBo support DDR2?
I have a p4 515
Socket (SKT) 775.
ASUS PTGD1-LA Mobo
HP/Compaq name: Grouper-UL8E
Used in many Compaq & HP Desktop Systems
Chipset : Intel 915p/915g
Max FSB speed 4x200Mhz(800MHz)
I ran SiSoft SAndra and It showed me in Max Installable memory ad 4GB and I currently have 512x2Mb DDR1
and In Supported Memory types it shoed DIMM DDR DDR2
What does this mean?? can I put DDR2 RAM too?
If yes than I can throw away my DDR and get 4 as many..
I wait for your replys
