You're completely confused about computers. Go buy a new computer, that thing needs DDR2 ram, which is hard to find and very expensive now. On top of that, it's maximum supported memory amount is 2x2GB, so you already maxed it out
I find it different that your more confused at my post then I am at computers... I clearly meant that I wanted to upgrade the ram to a faster version even (1330mhz is it?) is fast enough. I just want a speed upgrade and replace the 4 gigs with another 4 gigs that's faster. This is a yes or no question.
No:
1) It's pointless, since you get zero benefit from increasing memory speed if the CPU can't handle it
2) Your manual clearly states 800MHz is the limit
3) The absolute fastest DDR2 memory is 1200MHz, only DDR3 had 1333MHz and up (and both shared 1066MHz speeds even if the memory was completely different)
Basically, you're seriously confused about computers and think DDR2 and DDR3 are compatible. They are not the same thing and cannot be interchanged!
