128 GB DDR4 ECC RDIMM for Servers

This 128 GB DDR4 3200 ECC registered RDIMM targets workstation and server administrators who need high-density error-correcting memory. It suits infrastructure upgrades where data integrity and maximum capacity per slot are priorities. Standard desktop PCs cannot use this module.

Registered ECC Limits and Compatibility

Registered ECC memory requires a motherboard chipset and CPU that support registered DIMMs and ECC functionality. Mixing this 4Rx4 module with unbuffered DIMMs will prevent the system from booting. JEDEC DDR4 3200 operation at 1.2 V is the specified electrical envelope.

Installation Notes and Common Issues

The 288-pin DDR4 keying fits only DDR4 server slots; forcing it into a different generation damages the socket. All installed DIMMs should match capacity, speed and rank for stable operation. A missing heat spreader means airflow across the module must be adequate.

Questions sur cet article

Is the 128GB 4Rx4 module the right choice, or should I pick a lower-capacity or dual-rank option?

This part is a single 128GB 4Rx4 RDIMM. Choose it when your server board supports 4Rx4 registered DIMMs and you need maximum capacity per slot; otherwise select a lower-capacity or dual-rank module that matches your platform's qualified-vendor list.

What does DDR4 3200 (PC4-25600) CL22 deliver once installed in a compatible server?

The module operates at 3200 MT/s with CL22 timing at 1.2V, giving the rated JEDEC throughput for registered ECC memory when the memory controller runs at that speed.

Does the 288-pin registered ECC DDR4 interface limit mixing with other memory types?

Yes. The 288-pin registered ECC DDR4 RDIMM cannot be mixed with unbuffered or non-ECC DIMMs, and all populated slots should use identical registered ECC modules for stable operation.
