Upgrade the memory in your HP Z440, Z640, and Z840 workstations using the 4GB DDR4 2400 MHz RDIMM Memory Module from HP. This single RAM module features a 4GB capacity, a clock speed of 2400 MHz, a bus speed of PC4-19200, a 288-pin RDIMM form factor, and operates using 1.2V. Adding more RAM to your workstation lets you experience faster start-up times, run more programs at the same time, and easily toggle between several open programs. By offering Error Checking and Correcting technology, this RAM will help your workstation encounter fewer errors that can corrupt data sets and introduce system issues. As this RAM is also buffered, or registered, it places less electrical loads on the memory controller and allows single systems to remain stable with more memory modules than they would have otherwise. This RAM is protected by a limited 1-year parts replacement warranty.
Flexible & Fast Scalability
Improve start-up times with fewer delays during routine operations, run more programs simultaneously, and easily toggle between them with fast memory that you can scale to meet your requirements.
Ensure that all of your memory characteristics match by upgrading with HP-branded memory that's been tested for system-level integration with HP Workstations.
Benefit from Integrated ECC
Help avoid errors that can corrupt data sets and introduce system issues with Error Checking and Correcting technology that corrects single-bit memory errors.
Compatible with the Z440, Z640, and Z840 workstations
