32 GB DDR4 ECC RDIMM for Dell PowerEdge

This 32 GB DDR4 2933 MHz module is built for Dell PowerEdge R840, R940, R940xa and T640 servers. It delivers registered ECC reliability for workloads that demand data integrity. The module suits administrators extending existing infrastructure or building new server capacity.

Check your server requires registered ECC RDIMMs

Verify the target system accepts 288-pin DDR4 registered ECC memory before ordering. Standard desktop boards cannot use this module and it must not be mixed with unbuffered DIMMs. The platform must support 1.2 V operation and CL21 timing at 2933 MHz or a compatible lower speed.

No heat spreader simplifies dense slot layouts

The bare green PCB fits tight DIMM arrays without clearance issues common in multi-socket chassis. Gold-edge 288-pin connectors seat firmly in Dell PowerEdge slots for reliable contact over repeated thermal cycles. Registered buffering reduces electrical load on the memory controller for stable operation.

Questions about this item

Does the 32 GB DDR4 2933 MHz ECC RDIMM ship as a single module or a kit, and are any brackets or cables required?

The part number 2R9D42R432GB represents one 32 GB registered DIMM; no brackets, cables or additional hardware are included.

Should I choose this 32 GB CL21 module or a different capacity for my Dell PowerEdge R940?

This module provides 32 GB at 2933 MHz CL21; select the capacity that matches your server's maximum supported memory per slot and total population rules.

What does the 2933 MHz PC4-23400 rating mean once the module is installed in a PowerEdge T640?

The module will run at up to 2933 MHz CL21 at 1.2 V and will down-clock to 2666, 2400 or 2133 MHz if the platform requires a lower speed.
