System-specific DDR2 upgrade

This 8 GB kit delivers two 4 GB fully buffered DIMMs built for IBM System x3650 1914 and 7979‑xxx servers. Each module runs at DDR2‑667 (PC2‑5300) with CL5 timing and ECC protection for data integrity.

Suits maintainers of listed IBM servers.

The kit is validated only for the specified System x3650 models and will not function in desktops, workstations or servers that require unbuffered or registered DDR2 memory. Buyers needing larger per‑socket capacities or different form factors should look elsewhere.

Fully buffered ECC DDR2‑667 interface

The 240‑pin fully buffered design with ECC and 1.8 V operation is the single specification that determines compatibility; only systems accepting this exact memory type can use the kit.

Perguntas sobre este artigo

How much power do the two 4 GB DDR2-667 modules draw when the server runs continuously?

Each stick operates at 1.8 V; total draw depends on the IBM System x3650 1914 memory controller and workload.

What must the server already have for this 240-pin fully buffered kit to function?

The IBM System x3650 1914 or 7979-xxx must provide eight DDR2 FB-DIMM sockets arranged in four banks of two.

Will these CL5 2Rx4 modules work in the same bank as older PC2-5300 sticks I keep?

Yes, they match the DDR2-667 speed and ECC fully buffered specification used across all eight sockets of the 1914 and 7979-xxx platforms.
