HP 13L78AT 4GB DDR4 3200 Desktop RAM

4GB DDR4 3200 Desktop Memory

This HP 13L78AT module adds 4GB of DDR4 3200 memory to a desktop system. It uses the standard 288-pin DIMM form factor and runs at PC4 25600 speed with a CAS latency of CL1.5. The black module has no LED lighting and carries RoHS environmental certification.

Upgrade from lower-capacity or slower DDR4 modules

Replacing a smaller or slower DDR4 stick with this 4GB 3200 MHz module increases total memory bandwidth for everyday multitasking. The jump is worth it when the motherboard has a free 288-pin slot and supports the DDR4 3200 standard without requiring a voltage change.

Limited by the DDR4 3200 standard

The DDR4 3200 interface caps transfer rates at PC4 25600, so total throughput cannot exceed this ceiling even with tighter timings. A single 4GB module also restricts total system capacity unless additional identical sticks are installed in matched channels.
