128GB DDR4 3200 ECC LRDIMM for Gigabyte servers

This 128GB module targets administrators upgrading Gigabyte MZ32-AR0, MZ32-AR1, MZ71-CE0, MZ71-CE1 or MZ72-HB0 platforms. It delivers registered ECC load-reduced memory for multi-socket servers and workstations that require high capacity per slot. The module will not function in standard desktop boards or consumer laptops. Buyers needing unbuffered or standard registered DIMMs cannot use this product.

DDR4 3200 with backward speed steps

The JEDEC-standard PC4-25600 interface runs at 3200 MT/s with CL22 latency at 1.2V. The same module also operates at 2133, 2400, 2666 and 2933 MT/s when the platform demands a lower data rate. Load-reduced architecture reduces electrical load on the memory controller, enabling the 4Rx4 organisation at this density. Mixing with unbuffered or standard registered ECC DIMMs is not supported by the memory controller.

288-pin LRDIMM without heat spreader

The bare 288-pin PCB fits dense server DIMM arrays where tall heat spreaders would block adjacent slots or airflow ducts. Gold-edge contacts meet RoHS and JEDEC mechanical specs for reliable insertion cycles during maintenance. ECC load-reduced circuitry provides single-bit correction and multi-bit detection for data integrity in 24/7 workloads. Builders populating every channel should verify the platform's maximum rank count per channel before installing four-rank modules.

この商品に関する質問

Should I choose the 128GB 4Rx4 LRDIMM or a smaller capacity for my Gigabyte MZ32-AR0?

The 128GB 4Rx4 LRDIMM maximises density per slot, letting you reach higher total memory on the MZ32-AR0 without filling every DIMM socket.

What does the 3200MHz PC4-25600 rating deliver once installed in a Gigabyte MZ71-CE1 server?

The module runs at 3200MHz CL22 when the platform supports it, and will down-clock to 2933MHz, 2666MHz, 2400MHz or 2133MHz if the CPU or BIOS requires a lower speed.

How does the 288-pin DDR4 LRDIMM interface affect maximum capacity on a Gigabyte MZ72-HB0?

The 288-pin LRDIMM interface reduces electrical load on the memory bus, allowing the MZ72-HB0 to populate more slots with 128GB modules than standard registered DIMMs would permit.
