OWC 32GB DDR4 2933MHz CL21 ECC Registered RDIMM 2Rx4 memory upgrade

SKU CH-B0X8-W3BX4

32 GB DDR4 2933 MHz ECC registered RDIMM for Lenovo ThinkAgile VX servers

  • Capacity32GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 32GB

  • 32GB capacity expands server memory for larger workloads
  • DDR4 2933MHz speed delivers PC4-23400 bandwidth for Xeon SP Gen 2 platforms
  • ECC Registered design detects and corrects data errors in critical applications
  • 2V operation reduces power draw across 288-pin RDIMM modules
  • Validated for Lenovo ThinkAgile VX3320 VX3520-G VX5520 VX7320-N VX7520 systems

Targeted Server Upgrade

This 32 GB DDR4 2933 MHz CL21 ECC Registered RDIMM is built for Lenovo ThinkAgile VX3320, VX3520-G, VX5520, VX7320-N and VX7520 systems. It operates at 1.2 V on a 288-pin interface with a 2Rx4 rank structure. The module adds capacity to Xeon SP Gen 2 platforms that require registered memory with error correction.

Replaces Specific Lenovo Parts

This unit replaces Lenovo part numbers 01AG632, 4ZC7A08709 and 4ZC7A08742. The upgrade is worth it when those original modules are exhausted or when expanding total memory beyond the factory configuration. Backward compatibility with 2133 MHz, 2400 MHz and 2666 MHz buses allows deployment in mixed-speed channels without changing existing DIMMs.

Build Integration Constraints

The registered ECC design means this DIMM will not work in standard desktop boards or alongside unbuffered memory. It fits server, workstation and NAS platforms that accept 288-pin DDR4 RDIMMs. No heat spreader is fitted, so airflow in the chassis must be sufficient for passive cooling. Populating all slots with matched ranks keeps the memory subsystem stable.

Questions sur cet article

Does the 288-pin RDIMM fit the Lenovo ThinkAgile VX3320 server slots?

Yes, the 288-pin DDR4 RDIMM is designed for the ThinkAgile VX3320, VX3520-G, VX5520, VX7320-N and VX7520 systems.

What is the correct way to seat the registered ECC module so the server recognises all 32GB?

Align the notch with the slot key, press firmly until both retention clips click, and populate slots per the server manual to enable quad-channel operation.

When should the ECC registered DIMM be replaced in a ThinkAgile VX5520 running 24/7?

Replace if the system logs correctable ECC errors that exceed the platform threshold or if memory diagnostics report uncorrectable failures on this module.
