Server Memory Kit

This 16 GB kit contains two 8 GB DDR3 registered DIMMs built for enterprise servers. Each module carries ECC and registered buffering to protect data integrity in mission-critical workloads. The 240-pin form factor fits compatible DDR3 slots without modification.

Thermals and Power

DDR3 1866 modules operate at standard JEDEC voltage with no active cooling required. Passive heat spreaders dissipate warmth during normal multi-threaded server tasks. Registered signalling reduces electrical load on the memory controller for stable 24/7 operation.

Sustained Load Behaviour

ECC corrects single-bit errors on the fly during extended compute runs. Registered architecture maintains signal quality across fully populated channels under continuous bandwidth demand. The 2Rx4 organisation supports high-density configurations without timing degradation.

Questions about this item

How do I install the 240-pin DDR3 modules and what step is often missed?

Align the notch on each 240-pin DDR3 module with the slot key, press firmly until both retaining clips click, and confirm the motherboard detects the full 16 GB capacity in BIOS.

What maintenance or replacement will this ECC Registered kit need later?

ECC Registered DDR3 modules have no moving parts and require no scheduled maintenance; replacement is only needed if a module fails or capacity must be increased beyond 16 GB.

What limit appears first under sustained server workloads with this 1866 MT/s kit?

The DDR3 1866 (PC3 14900) speed ceiling is reached before the 2Rx4 registered organisation becomes a bottleneck, so sustained throughput tops out at the rated data rate.
