HP Compatible DDR4 Upgrade
This A-Tech module provides 8GB of DDR4 memory at 2400MHz with CL17 latency. It matches HP part numbers 860399-800 and 934800-001 as a direct replacement. The unbuffered DIMM operates at the standard 1.20V DDR4 voltage.
Office Systems Not ECC Servers
The module suits HP desktops that specify these part numbers for everyday workloads. Systems requiring ECC registered memory or a different DDR generation should use a different module. Verify the exact part number before ordering.
Steady 2400MHz Operation
Under sustained load the memory maintains its rated 2400MHz frequency and CL17 timing at 1.20V. The major-brand chipset and quality-assurance testing support consistent throughput. No heat spreader is fitted, so airflow in the chassis handles thermal management.

Questions about this item
My motherboard has 288-pin DDR4 slots — will this 262-pin DIMM fit?
The module is a 288-pin DDR4 DIMM; the 262-pin figure in the listing is a typo. It installs in any standard desktop DDR4 slot.
If I keep my current DDR4 2400 CL17 modules, will this stick run at the same speed and latency?
Yes — it is rated DDR4 2400 (PC4-19200) at CL17 and 1.20 V, so it will match the frequency, timing and voltage of identical modules.
After installation, how can I confirm the system sees the full 8 GB at 2400 MHz?
Open Task Manager → Performance → Memory or run CPU-Z; both will show 8 GB running at 2400 MHz with CL17 timings.
