Server ECC registered upgrade

This 32 GB DDR4 ECC registered DIMM is built for Cisco UCS B260 M4 E7 v4 and B460 M4 E7 v4 servers. It delivers error-correcting, registered memory for workloads that demand data integrity and uptime. It will not work in standard desktop PCs or with unbuffered and load-reduced modules.

Thermals noise and power draw

The module runs at 1.2 V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering and ECC logic add minimal overhead while maintaining signal integrity at 2400 MT/s. Power draw stays within JEDEC DDR4 limits for high-density server configurations.

Replacement part numbers and support

The DIMM replaces Cisco part numbers HXMR1X322RVA, HXSPM32RVA, UCSMR1X322RVA, UCSMR1X322RVARF and UCSMR1X322RVAS. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme. Buyers needing unbuffered ECC or consumer desktop memory should choose a different product.

Questions about this item

How do I install the 288-pin DDR4 ECC Registered DIMM in a Cisco UCS B260 M4, and which step is most often missed?

Power down the server, open the chassis, align the module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all 32GB are detected at 2400 MHz; the step most often missed is confirming the registered DIMM population order required by the B260 M4 memory riser guide.

What maintenance or replacement will this 32GB 2Rx4 module need during its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts. Replacement is only necessary if a memory diagnostic reports correctable ECC errors that exceed the platform threshold, at which point the single DIMM can be swapped without tools.

What limit appears first when this CL17 1.2V registered DIMM runs sustained workloads in a Cisco UCS B460 M4?

The memory controller’s maximum supported frequency of 2400 MHz is the first ceiling; the module cannot exceed its rated PC4-19200 speed, and the registered buffer adds one cycle of latency that becomes the bottleneck before voltage or thermal limits are reached.
