2 GB DDR2 FBD DIMM for desktop systems

This Simmtec module provides 2 GB of DDR2-667 fully buffered memory in a DIMM form factor. It carries the Hynix part number HYMP525F72CP4D3-Y5 and the HP service part 398707-051. The unit is supplied in new condition and is intended for desktop platforms that accept FBDIMM modules.

FBDIMM interface requirement

This module uses the fully buffered DIMM interface and will only operate in motherboards designed for FBDIMM memory. Standard DDR2 slots cannot accept it. Buyers who need conventional unbuffered DDR2 DIMMs must select a different part.

Questions about this item

What does the 667 MHz rating mean once this DDR2 module is installed in a real machine?

The 667 MHz rating indicates the module's maximum data transfer rate of 667 MT/s. Actual operating speed depends on the motherboard's memory controller and BIOS settings, which may run the module at a lower supported frequency.

What does the FBD interface cap in practice for this DDR2 DIMM?

The Fully Buffered DIMM interface uses an advanced memory buffer to reduce electrical load on the memory bus. This allows higher capacities and speeds than standard unbuffered DDR2, but requires a compatible FBDIMM motherboard chipset to function.
