Dell PowerEdge T640 Memory Upgrade

This 32GB DDR4 2933MHz module is built for Dell PowerEdge T640 tower servers. It delivers ECC registered reliability for workloads that require data integrity and continuous uptime. IT teams choose it to expand memory capacity in compatible Dell enterprise systems.

Registered ECC RDIMM Architecture

The 2Rx4 registered design places a register between the DRAM and the memory controller, reducing electrical load on the server board. ECC circuitry detects and corrects single-bit errors to protect critical applications. The 288-pin DDR4 form factor fits directly into available DIMM slots on the qualified platform.

Standard Voltage Operation

Rated at 1.20V, the module runs at the standard DDR4 voltage without requiring special power configuration. CL21 latency at 2933MHz provides stable timing for typical server workloads. The absence of a heat spreader keeps the profile low for dense memory populations.

Questions about this item

Does the CL21 latency become a bottleneck during sustained server workloads?

CL21 is the rated CAS latency for this DDR4 2933 module; sustained throughput depends on the Dell PowerEdge T640 memory controller and workload mix.

How much heat does the 1.20 V registered DIMM generate when running 24/7?

The module operates at 1.20 V without a heat spreader; registered DDR4 DIMMs typically stay within normal server thermal limits under continuous load.

Must the Dell PowerEdge T640 already have ECC registered memory installed to add this 32 GB stick?

The T640 requires DDR4 ECC RDIMMs; this 288-pin 2Rx4 module is designed for that platform and can be added to compatible existing configurations.
