Dell PowerEdge T420 server memory kit

This 32 GB kit contains four 8 GB DDR3 registered ECC modules designed specifically for the Dell PowerEdge T420. The modules operate at 1333 MHz with CL9 timing and 1.5 V voltage. They are validated for server workloads that require error correction and signal integrity.

Fits six sockets per processor in three banks

The T420 provides twelve total sockets across two processors with a maximum capacity of 384 GB. Each module is a 2Rx4 registered DIMM using 240-pin DDR3 form factor. Matching x4 DRAM modules within the same bank is required; mixing x4 and x8 parts inside one bank is not supported.

Sustained operation at rated 1333 MHz

Registered buffering and ECC maintain data integrity during continuous server duty. The CL9 9-9-9 timing delivers consistent latency without relying on short burst behaviour. Rated 1.5 V operation keeps power draw stable across all twelve slots when fully populated.

Questions about this item

Does the DDR3 1333 ECC Registered memory generate noticeable heat when running continuously in a Dell PowerEdge T420?

These modules operate at 1.5V without a heat spreader, so they rely on the server's internal airflow to stay cool during sustained workloads.

How many memory slots must be free in my Dell PowerEdge T420 to install this 4 x 8GB kit?

The kit occupies four of the twelve total DIMM slots, so you need at least four available sockets across the supported memory banks.

Will the 2Rx4 rank configuration work in the same memory bank as existing x8 modules?

The x4 and x8 DRAM versions must not be mixed within the same memory bank; use identical modules per bank for stability.
