Memory Upgrade in my Vaio FE21s

[Nox2]

Hi there. I have Vaio FE21s with this memoty type:
Storage capacity: 1 GB
DDR2 667 SDRAM
So-Dimm
533 MHz
HYS64T64020HDL-3.7-A
2x512 2Rx16
PC2-4200S-444-11-A0

And my question is can I put into this laptop this memory:

SAMSUNG
Specifications/Features
1GB
200-Pin SODIMM
Sixteen components (64M x 8-bit)
--->>****DDR2-667 / PC2-5300 ****<<--- in my is PC2-4200

Off-Chip Driver(OCD) Impedance Adjustment

Refresh and Self Refresh
DDR2 SDRAM Package: 60ball FBGA -64Mx8
All of Lead-free products are compliant for RoHS

I want to remove both 512 and put in 2x1GB of above memory type.

Or maybe if it will be ok with thi better to buy this one:

Kingston New 1GB DDR2-667

PC2-5300 CL5 200-Pin SODIMM
