Does DDR2 PC2-6400 Kingston ValueRAM RAM work fine on PB G4 15"(PB 5,8)?

I have a Powerbook G4 1.67Ghz dual layer hi-res (PowerBook5,8") and I want to upgrade memory.
Can I use DDR2 PC2-6400 800 Mhz instead of PC2-4200 DDR2 533 MHz?
In details I can get 2 KVR800D2S6/1G ( here are the specifications http://www.valueram.com/datasheets/KVR800D2S6_1G.pdf)
Will it the work?

Thanks for your help
