Server ECC RDIMM for Workstation Upgrades

This 8 GB DDR3 module runs at 1866 MHz with CL13 latency and 1.50 V operation. It is built as a registered DIMM with ECC for data integrity in server and workstation environments. The single-rank 1Rx4 organisation uses major-brand chips on a 240-pin form factor.

DDR3 Platform Voltage and Speed Ceiling

DDR3 memory tops out at 1.5 V standard voltage and 1866 MHz speed for this module class. Registered DIMMs add a clock cycle of latency compared to unbuffered types, which can limit peak bandwidth in latency-sensitive tasks. The PC3-14900 rating reflects the maximum theoretical throughput of this generation.

Keyed 240-Pin Installation and Compatibility Checks

The 240-pin keyed connector prevents incorrect insertion, but the module only fits motherboards that support DDR3 RDIMM ECC memory. Mixing registered and unbuffered DIMMs or exceeding the board's maximum rank count per channel will prevent boot. Verify the system manual for supported speeds, voltages and population rules before installing.

Questions about this item

Should I pick the 1Rx4 version or a dual-rank module for my server?

The 1Rx4 organisation places all eight gigabytes on a single rank, so the memory controller sees one logical rank per DIMM; this can allow higher total capacity per channel on platforms that limit the number of ranks.

What does the 1866 MHz speed rating mean once the module is installed?

The module runs at 1866 MT/s with a CAS latency of 13 cycles at the standard 1.5 V, delivering a peak transfer rate of PC3-14900 when the platform supports that data rate.

How does the 240-pin registered DDR3 interface limit performance in practice?

The 240-pin registered DDR3 interface caps the module at 1866 MT/s and 1.5 V operation; the register adds one clock cycle of address/command buffering, which is required for stability in multi-DIMM server configurations.
