Server memory kit for DDR3 platforms

This 64 GB kit contains four 16 GB registered DIMMs built for servers and workstations that require DDR3 1333 ECC memory. The modules operate at 1.5 V with a CAS latency of CL9 and use a dual-rank x4 organisation. They are not compatible with desktop or laptop computers.

Registered 240-pin DIMMs with ECC

Each module uses the 240-pin DDR3 form factor and includes error-correcting code plus registered buffering to reduce electrical load on the memory controller. The quad-channel kit layout supports multi-channel architectures common in server mainboards. Major-brand chips are used throughout and every module is tested before shipment.

Standard-voltage DDR3 thermals and power

Running at the standard 1.5 V DDR3 voltage, the modules draw typical power for registered DDR3 1333 memory under normal server workloads. Registered buffering and ECC add minimal overhead while maintaining signal integrity. No additional cooling beyond standard server airflow is required for rated operation.

Questions about this item

What speed does DDR3 1333 (PC3-10600) actually run at in a quad-channel server?

The modules operate at 1333 MHz with CL9 latency; the registered buffer adds one cycle of address/command delay, so sustained throughput is limited by the DDR3 1333 data rate.

Will these 240-pin RDIMMs fit a standard server DIMM slot?

Yes, each 16 GB module uses the 240-pin DDR3 DIMM form factor and the registered design matches server and workstation sockets that require RDIMMs.

How do I install the 4-module kit correctly, and what step is often missed?

Populate all four slots per the motherboard’s quad-channel guide, press each RDIMM until both ejector clips click, and verify in BIOS that all 64 GB are detected at 1333 MHz.
