4GB DDR2 667 Fully Buffered ECC Module

This 240-pin DDR2 667 (PC2 5300) module provides 4GB of server memory with ECC and fully buffered architecture. It runs at CL5 5-5-5-18 timings and 1.80V. The quad-rank design targets legacy platforms that require registered ECC DIMMs.

Not for non-ECC or unbuffered slots

Systems that accept only unbuffered non-ECC DDR2 cannot use this module. Buyers who need higher capacity per slot or a faster DDR2 speed grade should look elsewhere. Workstations without registered memory support will not post with these DIMMs.

Fully buffered ECC requirement

The fully buffered ECC design is the single specification that determines compatibility; the motherboard chipset must explicitly support FB-DIMM DDR2 667 registered memory for the module to function.

Questions about this item

Should I pick this 4 GB module or look for a different capacity?

This module is a single 4 GB stick. Add more identical sticks to reach the total memory your server board supports.

What does the PC2 5300 rating mean once the module is installed?

PC2 5300 indicates a maximum transfer rate of 5 300 MB/s at the rated DDR2 667 speed.

What does the fully buffered DDR2 interface cap in practice?

The 240-pin fully buffered DDR2 interface runs at 1.80 V with CL5 timing and tops out at the DDR2 667 data rate.
