What type of memory does the HP DV9788EG support?
The HP DV9788EG supports DDR2 667 MHz memory.
Is this RAM compatible with other HP models?
This RAM is specifically designed for the HP DV9788EG and may not be compatible with other HP notebook models.
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.
