HP 13L78AA 4 GB DDR4 3200 MHz desktop RAM

SKU CH-QP4Z-T1G2N MPN 13L78AA

4 GB DDR4 desktop DIMM at 3200 MHz with 288 pins, unbuffered and RoHS certified

  • 4 GB capacity adds responsive multitasking headroom
  • 3200 MHz DDR4 speed keeps data flowing quickly
  • 288-pin DIMM form factor fits standard desktop slots
  • Unbuffered signal processing reduces latency for everyday tasks
  • RoHS certified materials meet environmental standards

Memory capacity and type

This module provides 4 GB of DDR4 memory for desktop systems. It operates at 3200 MHz with an unbuffered signal design. The 288-pin DIMM form factor fits standard desktop slots. RoHS certification confirms environmentally friendly manufacturing.

Target system fit

The single 4 GB capacity suits basic office workstations or entry-level upgrades. Builders needing higher bandwidth for content creation or gaming should consider larger kits. Systems limited to lower memory speeds will not utilise the full 3200 MHz rating.

Decisive specification

The 4 GB density determines whether this module meets your workload requirements. Dual-channel performance requires a matching second stick of identical specification. Verify motherboard support for DDR4-3200 before purchase.

Questions about this item

What comes inside the HP 13L78AA 4 GB DDR4 3200 MHz desktop RAM box and what must be purchased separately?

The box contains a single 288-pin DIMM module. No cables, brackets or additional components are included; a compatible motherboard with a free DDR4 slot is required separately.

Which capacity or version of the HP 13L78AA should I choose for my upgrade?

This part number identifies one specific 4 GB DDR4-3200/PC4-25600 unbuffered DIMM. Select it when you need exactly 4 GB at 3200 MHz; other capacities carry different part numbers.

What does the 3200 MHz rating mean once the HP 13L78AA is installed in my desktop?

The module is rated to run at 3200 MHz (PC4-25600). Actual operating speed depends on the motherboard and CPU memory controller; it will clock down if the platform supports a lower maximum.
