Memory modules The computer comes with at least one small outline, dual in-line memory module (SODIMM). To achieve maximum memory support, you can populate the system board with up to 32 GB of memory. Memory module specifications For proper system operation, the memory modules must meet the following qualifications: Component Memory modules Compliance Pins Support Slots Maximum memory Supported Note Specification 1.2 volt DDR4-SDRAM memory modules unbuffered non-ECC PC4-19200 DDR4-2400 MHz-compliant industry-standard 260-pin containing the mandatory Joint Electronic Device Engineering Council (JEDEC) specification support CAS latency 17 DDR4 2400 MHz (17-17-17 timing) 2 32 2 Gbit, 4 Gbit, 8 Gbit, and 16 Gbit non-ECC memory technologies single-sided and doublesided memory modules The system will not operate properly if you install unsupported memory modules. Memory modules constructed with x8 and x16 DDR devices are supported; memory modules constructed with x4 SDRAM are not supported. HP offers upgrade memory for this computer and advises that the consumer purchase it to avoid compatibility issues with unsupported third-party memory. Removing memory modules For a list of available memory modules, see Computer major components on page 3. There are two memory module slots on the system board, with one slot per channel. The slots are labeled DIMM1 and DIMM3. The DIMM1 slot operates in memory channel B. The DIMM3 slot operates in memory channel A. 30 Chapter 4 Removal and replacement procedures
