Axiom

Axiom 805351-B21-AX 32GB DDR4 ECC Registered DIMM 2400MHz CL17 288-pin memory card

SKU CH-Z1YM-48P3B MPN 805351-B21-AX

32 GB DDR4 ECC registered DIMM running at 2400 MHz with CL17 latency and 1.20 V operation

  • 32 GB capacity supports large server workloads
  • DDR4 2400 MHz speed delivers 19200 MT/s bandwidth
  • ECC registered design detects and corrects data errors
  • CL17 latency at 1.20 V balances response and efficiency
  • 288-pin DIMM fits standard server memory slots

Server-grade capacity

This Axiom DIMM delivers 32 GB of DDR4 memory for servers and workstations that require error-correcting code protection. The registered signal processing and ECC support help maintain data integrity in multi-module configurations. It operates at 1.20 V and carries a RoHS environmental certification.

Upgrade from non-ECC or lower density

Replacing unbuffered non-ECC modules with this registered ECC DIMM adds error detection and correction for critical workloads. The jump is worth it when system stability outweighs the slight latency increase from registered buffering. CL17 timing at 2400 MHz provides consistent throughput for supported platforms.

Verify motherboard and CPU support

Confirm the platform accepts 288-pin DDR4 registered ECC DIMMs and can run at the PC4-19200 data rate. Mixed populations of registered and unbuffered modules are not supported on the same channel. Check the qualified vendor list for 32 GB single-rank or dual-rank compatibility before ordering.

Questions about this item

Does the 288-pin DIMM fit my server motherboard?

The module uses the standard 288-pin DDR4 DIMM form factor and requires a compatible DDR4 registered DIMM slot.

How do I install the 32GB ECC registered module correctly?

Align the notch with the slot key, press firmly until both retention clips click, and ensure the registered buffer is supported by the platform.

Will the ECC registered 2400MHz memory need replacement or firmware updates?

ECC registered DIMMs have no moving parts or firmware; they operate for the system life unless a correctable error rate exceeds platform thresholds.
