Server-grade ECC RDIMM upgrade

This 64GB DDR4 3200MHz CL22 registered module is built for Dell PowerEdge R7515, R7525, T550, XR11 and XR12 systems. It delivers ECC error correction and registered buffering required by those platforms. It will not work in standard desktop computers and cannot be mixed with unbuffered memory.

Thermals and power profile

Operating at 1.2V, the module runs without a heat spreader and conforms to JEDEC DDR4 specifications. Typical server airflow keeps temperatures in check during sustained workloads. Power draw remains low for a 64GB registered DIMM.

Build and installation notes

The 288-pin RDIMM fits directly into the compatible Dell PowerEdge slots. No extra cables or brackets are needed. OWC tests every module in-house and backs it with a limited lifetime warranty and free technical support. Replaces Dell part numbers 370AEVP, AA783423, AA799110, AA810828, AB214253, P2MYX, SNPP2MYXC/64G and SNPP2MYXC/64VXR.

Questions sur cet article

How do I install this 288-pin DDR4 RDIMM in a Dell PowerEdge R7515, and what is the common mistake?

Align the notch on the module with the slot key, press firmly until both side clips click, and ensure all installed DIMMs match in capacity, speed, and manufacturer to avoid mismatched-channel errors.

What maintenance or replacement will this ECC Registered memory need over time?

No scheduled maintenance is required; if a module fails, replace it with an identical 64GB DDR4 3200 CL22 1.2V 2Rx4 RDIMM to keep ECC protection and registered signalling consistent.

What limit appears first when this memory runs under sustained server workloads?

The CL22 latency at 3200 MT/s sets the timing boundary, so sustained throughput is capped by the 25600 MB/s data rate and the registered buffer's single-cycle overhead.
