Server-grade memory kit

The Computer Memory Solutions CM512725300FBDIMM kit delivers 16GB across four 4GB fully buffered DDR2 modules. It targets administrators maintaining Intel MFS5000SI or S5000VSA/S5000VSAR servers that require ECC protection. Each stick uses a 240-pin interface and operates at 1.8V.

Sustained operation

Fully buffered architecture moves the memory controller onto the module, reducing electrical load on the system board during continuous workloads. ECC circuitry corrects single-bit errors in real time, preventing data corruption during long compute runs. CL5 timing at 667 MHz provides deterministic latency for multi-threaded server tasks.

Upgrade path

The kit fills four of the eight available sockets, taking the system from a lower capacity toward the 32GB maximum supported by the platform. It suits environments that must retain DDR2 infrastructure and cannot migrate to newer memory generations. Buyers needing larger single-module densities or non-ECC memory should look elsewhere.

Questions about this item

How much power do these 1.8 V fully buffered modules draw when the server runs continuously?

Each module operates at 1.8 V; fully buffered DDR2 DIMMs typically draw more power than standard registered DIMMs, so ensure the server's power budget accounts for four sticks running at DDR2 667 speed.

What motherboard slot type is required to install these 240-pin FB-DIMMs?

The kit uses 240-pin DDR2 fully buffered DIMMs, which only fit motherboards with FB-DIMM slots — standard DDR2 registered DIMM sockets will not accept them.

Will these CL5 667 MHz modules run at their rated speed in an Intel S5000VSA server that currently uses slower DDR2 memory?

The server's memory controller sets the bus speed; if the board supports DDR2 667, the kit will run at 667 MHz, otherwise it will downclock to the highest speed the platform allows.
