HP 4GB DDR3L-1333 ECC Registered Low Voltage DIMM — 647647-371

The HP 647647-371 is a 4GB DDR3L-1333 (PC3-10600) ECC Registered DIMM operating at 1.35V, built for HP ProLiant Gen7 and Gen8 servers. Its low-voltage design reduces power consumption while the registered architecture ensures signal integrity in multi-DIMM server configurations requiring ECC reliability.

Frequently Asked Questions

What does the -371 suffix mean on HP part number 647647-371?

The -371 suffix denotes an HP factory/regional configuration variant. It is functionally equivalent to the standard option kit version of the same module.

Is 647647-371 backward compatible with 1.5V DDR3 RDIMM slots?

Yes — DDR3L modules are designed to operate at both 1.35V and 1.5V. In platforms that only support 1.5V DDR3, this module will run at 1.5V, foregoing the low-voltage power savings.

Can 647647-371 be installed in HP ProLiant Gen9 servers?

Gen9 servers use DDR4 memory and do not support DDR3 modules. This module is compatible with Gen7 and Gen8 DDR3 platforms only.
