64GB DDR4 Load Reduced DIMM
This 64GB DDR4 2666 Load Reduced DIMM from SK hynix is built for Intel S7200AP servers that require ECC memory. It targets administrators expanding virtualization hosts, in-memory databases or high-performance computing clusters. The module uses a 288-pin DDR4 SDRAM form factor and operates at 1.20V with CL19 latency. It is not for standard desktops or workstations that accept only unbuffered UDIMMs.
DDR4 2666 speed and LRDIMM architecture
The DDR4 2666 interface caps transfer rates at PC4 21300, limiting peak bandwidth compared to faster DDR4 grades. Load Reduced technology removes the rank-per-channel ceiling found on standard RDIMMs, allowing more modules per channel for higher total capacity. Systems not designed for LRDIMMs cannot use this module, and mixing it with registered or unbuffered ECC DIMMs is unsupported. The 4Rx4 organisation helps density but does not overcome the bus speed limit.
288-pin installation and compatibility checks
Installation follows the standard 288-pin DDR4 slot procedure, but the server must explicitly support Load Reduced DIMMs in its memory controller and BIOS. A common error is inserting these modules into platforms qualified only for RDIMMs or UDIMMs, which prevents boot. Verify the Intel S7200AP memory population rules for 4Rx4 LRDIMMs before purchasing. No heat spreader is fitted, so airflow across the modules must be maintained by the chassis design.

商品問答
Should I choose the 64GB LRDIMM or a smaller RDIMM for my Intel S7200AP server?
The 64GB Load Reduced DIMM removes channel ranking limits, letting you install more modules per channel for higher total capacity than standard RDIMMs allow.
What does the DDR4 2666 speed deliver inside a running server?
It provides PC4 21300 bandwidth at CL19 latency, giving virtualization and in-memory databases the throughput they need for heavy workloads.
How does the Load Reduced interface affect memory density limits?
LRDIMM buffering eliminates the rank restrictions of standard RDIMMs, so you can populate more DIMM slots per channel and reach densities up to 128GB per module.
