Is this memory compatible with my Sony VAIO VGN-FS415E?
Yes, this 2GB DDR2-667 SODIMM kit is designed for the VGN-FS415E and compatible VAIO FS series notebooks. Verify your system supports 2GB total capacity before upgrade.
What is the speed difference between DDR2-667 and DDR2-533?
DDR2-667 (PC2-5300) runs at 667MHz versus 533MHz for DDR2-533 (PC2-4200). The 667MHz variant offers approximately 25% higher bandwidth, improving system responsiveness.
Can I mix this with existing RAM?
Yes, you can mix DDR2-667 with same-speed modules. Avoid mixing different speeds (667 and 533MHz) as the system will downclock to the slower module's speed.
What is the voltage requirement?
DDR2-667 modules operate at 1.8V, which is standard for DDR2. This matches the VAIO VGN-FS415E specifications.
How do I install this memory?
Power off the laptop, remove the battery, locate the SODIMM slots, insert modules at a 45-degree angle, then press down firmly until retention clips lock on both sides.
Is this ECC memory?
No, this is standard non-registered DDR2 memory. ECC is not required for the VAIO VGN-FS415E.
