Server-specific DDR3 ECC kit

This 16 GB kit contains two 8 GB DDR3-1333 ECC unregistered DIMMs built for the IBM System x3250 M4 2583-xxx series. Each module runs at 1.5 V with CL9 9-9-9 timings on a 240-pin interface. The memory is validated only for that server platform.

Straightforward DIMM installation

Power down the server, open the chassis and insert each module into the four available ECC UDIMM slots until the retention clips lock. No driver or BIOS update is required. The kit will not work in systems that demand registered or load-reduced DIMMs, nor in consumer boards that lack ECC support.

16 GB dual-channel capacity

The server supports a maximum of 32 GB across its four sockets, so this 16 GB kit fills half the capacity. Builders needing the full 32 GB limit must add a second identical kit. Workstations or PCs that cannot use ECC unregistered DDR3 cannot use these modules.

Questions about this item

How can I confirm the 1333 MHz DDR3 kit is running at the correct speed after installation?

Enter the system BIOS or UEFI and check the reported memory frequency; it should read 1333 MHz (PC3-10600) for each of the two 8 GB modules.

What exactly ships in the box and is anything else required to install it in an IBM System x3250 M4 2583-xxx?

The package contains two 240-pin DDR3 ECC unregistered DIMMs totalling 16 GB; no additional parts are needed for the supported server.

Which capacity option should I choose if the server has four ECC UDIMM sockets and a 32 GB maximum?

This 16 GB (2 x 8 GB) kit fills half the sockets and leaves room to add another identical kit later to reach the 32 GB limit.
