4GB DDR4 2666MHz Desktop Memory

This A-Tech module provides 4GB of DDR4 memory at 2666MHz with CL19 latency. It uses the standard 288-pin DIMM form factor and operates at 1.20V. The unbuffered, non-ECC design suits everyday desktop workloads and general multitasking.

Suits owners of compatible Dell systems

The module is listed as a direct replacement for Dell part numbers AA086414 and SNPCND02C/4G. Builders needing ECC error correction or registered memory should select a different part, as this stick is non-ECC and unbuffered.

2666MHz DDR4 speed with CL19 timing

The tested frequency is 2666MHz (PC4-21300) and the CAS latency is CL19. Verify that your motherboard and CPU support this data rate before purchase, as the module will only run at speeds the platform allows.

Questions sur cet article

Should I choose the 4GB module or look for a different capacity?

This listing is a single 4GB DDR4 2666MHz CL19 DIMM; select it if your system needs exactly one 4GB stick or if you are adding to an existing 4GB module to reach 8GB total.

What does the 2666MHz speed actually deliver inside a desktop?

The module runs at DDR4 2666MHz (PC4-21300) with CL19 latency at 1.20V, giving standard JEDEC bandwidth for everyday multitasking and office workloads.

Does the 288-pin DDR4 DIMM interface limit the speed to 2666MHz in practice?

Yes, the 288-pin unbuffered DIMM is rated for DDR4 2666MHz (PC4-21300) and will operate at that frequency when the motherboard supports it.
