Dell PowerEdge T640 DDR4 module

This 32 GB DDR4 RDIMM is built for the Dell PowerEdge T640 server. It provides registered ECC memory for workloads that require data integrity and system stability. The single-module design lets administrators add capacity one slot at a time.

DDR4 2933 registered ECC limits

The DDR4 2933 interface caps transfer rates at PC4-23400 while the registered buffer adds one cycle of latency. ECC operation consumes extra bits per word, so usable bandwidth is lower than the raw clock suggests. Systems that do not support registered DIMMs cannot use this module.

32 GB 2Rx4 capacity decision

The 32 GB density delivered in a 2Rx4 organisation determines whether the server reaches its target memory footprint within the available DIMM slots. Buyers who need higher per-slot density or a different rank structure must choose another part.

Questions about this item

Should I pick the single 32 GB module or look for a kit of smaller sticks?

This listing is a single 32 GB RDIMM; add identical modules to fill the Dell PowerEdge T640’s memory channels for best bandwidth.

What does the 2933 MT/s rating actually deliver inside a PowerEdge T640?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency, giving the server its rated throughput when populated per Dell’s memory-configuration rules.

Will the 288-pin ECC RDIMM fit and work in a standard desktop motherboard?

No — the registered buffer and ECC require a server chipset; it is validated for the Dell PowerEdge T640 and similar Dell DDR4 RDIMM platforms.
