HPE 128GB 4Rx4 DDR5-5600 Registered 3DS SmartMemory Kit

The HPE P64709-B21 is a 3DS registered DIMM: 128GB built with stacked chips in a 4Rx4 layout, with ECC and a 5600 MT/s data rate. The CAS latency is 52.

The latency figure is higher than on smaller modules, which is a typical result of stacking. For workloads that care about capacity more than the last bit of access time, such as large in-memory databases and virtualization hosts, that trade-off is acceptable.

Four ranks per module means the server's rank limits per channel apply, so read the population guide for your model. Avoid mixing 3DS modules with standard RDIMMs unless the platform documentation allows it.

Choose this kit when your processors support 5600 MT/s and your memory plan calls for 128GB modules.

The kit is available in all three conditions. New and refurbished carry a choice of 1 year or 3 years of warranty, and used carries 90 days. Add P64709-B21 to your RFQ list with the count you want.
