4GB DDR3 ECC RDIMM for servers

This 4GB DDR3 ECC registered DIMM runs at 1333 MHz with CL9 latency at 1.50V. It targets administrators maintaining DDR3-era servers or workstations that require registered, error-correcting memory. The single 240-pin module uses a 2Rx8 organisation and major-brand chips.

Fits registered DDR3 slots in compatible systems

The module installs in 240-pin DDR3 DIMM sockets that support registered ECC operation at PC3-10600 speed. It requires a platform that accepts registered memory and will not function in consumer boards limited to unbuffered DIMMs. Verify your system's qualified vendor list before installation.

Replaces specific Kingston part numbers

This unit serves as a direct equivalent for Kingston KVR1333D3D8R9S/4G, KTM-SX313L8/4G and KVR13R9D8/4I. The cross-reference simplifies sourcing when those exact part numbers are specified in maintenance documentation or vendor-qualified configurations.

Questions about this item

Will the 1.5 V requirement stay within my server's power budget under sustained load?

The module runs at the standard DDR3 1.50 V, so power draw is predictable and matches typical server DIMM specifications.

Does the registered ECC design add noticeable heat or fan noise during all-day operation?

Registered ECC DIMMs run at the same 1.50 V as standard DDR3 and do not generate extra heat or noise beyond normal server memory.

My motherboard has 240-pin DDR3 slots — is that the only requirement for this module to work?

Yes, it fits 240-pin DDR3 slots, but the board must also support ECC registered (RDIMM) memory and 2Rx8 organisation.
