Server Memory Upgrade

This 32GB DDR3L ECC registered DIMM operates at 1600MHz with CL11 latency and 1.35V. It is built for Dell PowerEdge R815, R820, T320, T420 and T620 servers requiring 240-pin 4Rx4 modules. The single stick adds capacity without mixing registered and unbuffered memory.

Replaces Standard Modules

The upgrade suits administrators replacing lower-density DDR3L sticks or filling empty slots in compatible PowerEdge chassis. It is not for desktop PCs, workstations that require unbuffered memory, or systems that cannot accept registered ECC DIMMs. The jump is worth it when ECC error correction and registered signalling are mandatory.

Sustained Load Behaviour

JEDEC-compliant DDR3L construction maintains rated 1600MHz throughput under continuous server workloads. Registered buffering reduces electrical load on the memory controller during extended operation. ECC corrects single-bit errors in real time, preserving data integrity without performance drops during long-running tasks.

Questions about this item

Will the 240-pin DDR3L form factor fit my Dell PowerEdge T620 memory slots?

Yes, the 240-pin DDR3L RDIMM matches the registered DIMM slots used in the PowerEdge T620 and the other listed Dell servers.

What is the correct way to seat this registered ECC module, and what mistake should I avoid?

Align the notch with the slot key, press firmly until both retention clips click, and do not mix this registered module with any unbuffered memory.

When should I expect to replace this 32GB module, and what indicates it is failing?

ECC registered DDR3L modules typically run for many years; replace if the system logs corrected memory errors or fails to POST during boot.
