4GB DDR3 1600 ECC RDIMM for Servers

This 4GB DDR3 1600 module is a registered ECC DIMM built for server and workstation platforms that require error-correcting memory. It runs at PC3-12800 speed with CL11 latency at the standard 1.5V voltage. The 2Rx8 organisation uses major-brand chips and a 240-pin form factor.

Ideal for Dell part-number matches.

This module suits administrators replacing Dell parts such as A6996786 or SNPD65JJC/4G in compatible PowerEdge or Precision systems. Builders whose motherboards accept only unbuffered non-ECC UDIMMs should look elsewhere, as registered ECC memory will not function in those platforms.

Registered ECC with 2Rx8 organisation

The single specification that determines fit is the registered ECC RDIMM design combined with a 2Rx8 rank structure. Only systems that explicitly support registered ECC DDR3 DIMMs at 1600 MT/s can use this module.

Questions about this item

Will this 240-pin DDR3 RDIMM fit a board that only takes UDIMMs?

No — the module is a registered DIMM (RDIMM) and requires a motherboard that supports registered memory; it will not work in a UDIMM-only slot.

Can I add this ECC RDIMM to a system that already has non-ECC unbuffered DDR3 installed?

No — registered ECC modules cannot be mixed with unbuffered non-ECC memory; the board must support registered ECC and all populated slots should use matching RDIMMs.

How can I confirm the module is running at DDR3 1600 CL11 1.5 V after installation?

Check the BIOS or a tool such as CPU-Z — it should report 1600 MT/s, CL11 timings and 1.5 V for this module.
