512 GB DDR4 3200 ECC LRDIMM kit

This 512 GB kit contains two 256 GB DDR4 3200 modules built as load-reduced DIMMs with ECC. The 288-pin DIMMs run at 1.20 V with CL22 latency and use 2S4Rx4 octal-rank 3DS/TSV organisation. They are designed for servers and workstations that require registered ECC memory.

Server and workstation upgrades only

This memory suits administrators expanding capacity in DDR4 platforms that support 256 GB LRDIMMs per slot. It is not for desktop or laptop systems, which cannot use load-reduced ECC modules. Builders needing unbuffered UDIMMs or standard RDIMMs should look elsewhere.

256 GB per module density

Each module provides 256 GB in a single 288-pin LRDIMM using 2S4Rx4 3DS/TSV rank structure. Verify that your server or workstation chipset and BIOS support this density and rank configuration before purchase.

Pitanja o ovom artiklu

How does the 512GB capacity of this kit translate to usable memory in a server?

The kit provides two 256GB LRDIMM modules, giving 512GB total DDR4 ECC memory that the operating system can address directly for large datasets and virtualization workloads.

What does the PC4-25600 rating mean for real-world bandwidth?

PC4-25600 indicates a peak transfer rate of 25,600 MB/s per module at DDR4 3200 MT/s; actual throughput depends on the server's memory controller and channel configuration.

Will these 288-pin LRDIMMs fit in a standard server DIMM slot?

Yes, they use the standard 288-pin DDR4 DIMM form factor and require a server or workstation motherboard with LRDIMM support and 2S4Rx4 rank compatibility.
