4GB DDR3 1333 ECC RDIMM Server Memory

This 4GB DDR3 1333 ECC RDIMM module provides registered, error-correcting memory for server and workstation platforms. It operates at PC3-10600 speed with CL9 latency and standard 1.5V voltage. The 2Rx8 dual-rank organisation uses major-brand chips on a 240-pin DIMM. It serves as a direct replacement for HP part numbers 500658-B28 and 654559-888.

Suits servers needing registered ECC DDR3 capacity

This module fits systems that require registered ECC DDR3 DIMMs at 1333 MHz. Builders whose platforms accept only unbuffered non-ECC memory or a different DDR generation cannot use this part. Systems limited to single-rank modules or a lower voltage standard also fall outside its specifications.

Registered ECC with 2Rx8 organisation

The registered buffer and ECC function together with the 2Rx8 rank structure determine whether the memory controller can initialise the module. Verify that your motherboard or server documentation explicitly supports registered ECC DDR3 DIMMs with dual-rank 2Rx8 layout before purchase.

Questions about this item

Does my server need a DDR3 240-pin registered DIMM slot to use this 4GB module?

Yes, this is a DDR3 1333 MHz PC3-10600 ECC RDIMM with a 240-pin form factor, so the motherboard must provide a registered DDR3 DIMM slot.

Can I add this 2Rx8 registered ECC stick alongside older unbuffered non-ECC DDR3 modules I already have?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC UDIMMs; the memory controller requires all installed modules to share the same registered ECC type.

After installing the module, how can I confirm the system sees it running at 1333 MHz with ECC active?

Check the BIOS memory information or run a tool such as dmidecode on Linux to verify the reported speed is 1333 MT/s and the type shows registered ECC.
