Targeted Server Upgrade

This 32GB kit contains four 8GB DDR3-1333 ECC registered DIMMs validated for the Dell PowerEdge R420. It is designed for administrators who need to expand memory capacity on that specific platform without mixing registered and unbuffered modules.

Registered ECC Reliability

Each module uses a 240-pin interface, operates at 1.5V with CL9 9-9-9 timing, and implements 2Rx4 organisation for error correction and signal buffering. The registered design reduces electrical load on the memory controller, allowing the R420 to populate all twelve DIMM sockets across two processors while maintaining data integrity.

Capacity Step for R420

The kit adds 32GB toward the system maximum of 384GB for registered ECC configurations, replacing lower-density modules or filling empty sockets. It is not suitable for workstations or consumer boards that require unbuffered non-ECC memory, nor for any platform outside the validated Dell PowerEdge R420 compatibility list.

Questions about this item

What does the PC3-10600 DDR3-1333 rating mean for real-world bandwidth?

PC3-10600 is the JEDEC designation for DDR3-1333; each module is rated for 10600 MB/s peak transfer.

How many 240-pin DDR3 slots does the Dell PowerEdge R420 provide for this kit?

The R420 has 12 DIMM sockets total, six per processor, so the four-module kit occupies one bank per CPU.

What installation step is most often missed when populating the R420 with registered ECC DIMMs?

The system requires identical ranks within each memory bank; mixing 2Rx4 modules with x8-based parts in the same bank is not supported.
