128 GB DDR4 ECC LRDIMM for Gigabyte Servers

This 128 GB DDR4 3200 ECC Load Reduced DIMM is built for Gigabyte R152-Z30, R152-Z31, R152-Z32, R152-Z33 and R162-Z10 systems. It targets server and workstation operators who need maximum registered capacity per slot. Standard desktop boards cannot use this module type.

Check slot type and memory population rules

Verify that your platform accepts 288-pin LRDIMM modules and that the BIOS supports 4Rx4 organisation at 1.2 V. This memory must not be mixed with unbuffered or standard registered DIMMs. Confirm the qualified vendor list for your specific Gigabyte model before installation.

Steady throughput under continuous load

Rated at 3200 MT/s with CL22 timing, the module maintains JEDEC-standard bandwidth during extended compute jobs. Backward compatibility with 2133, 2400, 2666 and 2933 MT/s allows stable operation if the platform downclocks. ECC correction protects data integrity throughout sustained workloads.

Questions about this item

Does the module come with any accessories or does it ship as a bare stick?

The module ships as a single 288-pin DDR4 ECC LRDIMM without additional accessories; no cables or brackets are included.

Which capacity and rank option should I select for a Gigabyte R152-Z30 server?

This is a single 128 GB 4Rx4 module; choose it when your server requires one 128 GB load-reduced DIMM per slot.

What does the 3200 MHz CL22 rating mean when the module is installed in a compatible server?

The module runs at DDR4 3200 (PC4-25600) with CAS latency 22 and will down-clock to 2133, 2400, 2666 or 2933 MHz if the platform requires it.
