  • 128 GB capacity lets servers handle larger workloads
  • ECC load-reduced design maintains data integrity under heavy use
  • DDR4 3200 speed with CL22 latency delivers responsive performance
  • 2 V operation reduces power draw in dense configurations
  • Validated for Gigabyte MZ72-HB2 and R152-P30 through P33 systems

Target System Compatibility

This 128GB DDR4 3200 ECC LRDIMM is built for the Gigabyte MZ72-HB2 and R152-P30 through R152-P33 platforms. It serves workstations, servers and NAS appliances that require load-reduced registered memory with error correction. The module will not function in standard desktop computers and cannot be mixed with unbuffered or registered ECC DIMMs.

Installation Notes

The 288-pin form factor seats in the server board's DDR4 slots like any DIMM, but the platform must explicitly support load-reduced ECC at 1.2V. Common issues arise when the module is paired with registered or unbuffered memory, or when the BIOS is not updated for 4Rx4 density. Verify the system's qualified-vendor list before fitting.

Sustained Load Behaviour

Rated at CL22 and PC4-25600, the module runs at 3200MHz and drops to 2933, 2666, 2400 or 2133MHz when the platform dictates. Load-reduced buffering lowers electrical load on the memory controller during continuous throughput, while ECC corrects single-bit errors in real time. The JEDEC-standard design maintains stability across extended server workloads.

Perguntas sobre este artigo

How do I verify the 128GB DDR4 3200 ECC LRDIMM is recognised at full speed after installation?

Enter the system BIOS or UEFI and confirm the memory shows 128GB capacity, 3200MHz speed, CL22 latency and ECC Load Reduced status.

What comes in the box and do I need any extra parts to install the module?

The box contains the single 288-pin DDR4 ECC LRDIMM module; no additional cables, brackets or tools are required for installation in a compatible server slot.

Which capacity and rank should I choose for a Gigabyte MZ72-HB2 or R152-P30 through P33 server?

Select the 128GB 4Rx4 LRDIMM to match the validated part number 3L2D44R4128G for those Gigabyte models.
