HP-Compatible Desktop Upgrade

This A-Tech module is a direct replacement for HP part numbers L26005-001 and L36847-001. It delivers 4GB of DDR4 memory in a single unbuffered DIMM for desktop systems needing a straightforward capacity increase.

Standard Voltage and Latency

The stick runs at the standard DDR4 voltage of 1.20V with a CAS latency of CL19 at 2666 MT/s. Without a heat spreader, it relies on normal case airflow and adds minimal thermal load or acoustic contribution to the system.

Steady Workload Behaviour

Under sustained use the module maintains its rated 2666 frequency and 1.20V level without throttling. The major-brand chipset and factory testing support consistent throughput for extended multitasking or background tasks rather than short bursts only.

商品問答

Will this 4 GB DDR4 2666 CL19 module fit my HP desktop that uses part numbers L26005-001 or L36847-001?

Yes, the module is built as a direct replacement for those HP part numbers and matches the required DDR4 2666 specification.

Does my motherboard need to support unbuffered non-ECC DDR4 at 1.2 V to use this memory?

Yes, this is a standard 1.2 V unbuffered non-ECC DIMM, so the board must accept that type.

What does the CL19 timing mean for everyday use?

CL19 is the CAS latency at 2666 MHz; it determines how quickly the memory can start a read operation and is typical for standard desktop DDR4.
