Kingston Technology Corp. KVR1333D3D4R9S/8GHB 8GB DDR3 1333 ECC Registered server RAM

8 GB DDR3 ECC Registered Module

This 8 GB DDR3 module is built for servers and workstations that require error-correcting registered memory. It suits system integrators and IT departments assembling or repairing platforms that use 240-pin DDR3 slots and mandate ECC for data integrity.

Registered DDR3 1333 bus limits

The registered design adds a clock cycle of buffering, so the memory controller must support registered DIMMs and the DDR3 1333 JEDEC standard. Unbuffered or non-ECC platforms will not accept this module, and faster DDR3 speeds are not guaranteed without matching controller qualification.

Single-rank versus dual-rank x4 organisation

This stick uses a dual-rank x4 layout, which affects how many ranks the memory controller sees per channel. Buyers who need a single-rank module for dense configurations or specific rank-count limits should select a different part.
