Capacity and compatibility

This 4GB DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It is built as a non-ECC unbuffered DIMM for desktop systems and uses major-brand chips. The stick is listed as a compatible equivalent for Dell part numbers AB371020 and SNP36FTXC/4G.

Build quality and connectors

The memory uses a standard 288-pin DIMM form factor that fits regular desktop slots. All modules undergo quality-assurance testing before shipping to ensure dependable performance. Verification of your system's supported memory specifications is recommended prior to installation.

Thermals and power

Operating at the standard DDR4 voltage of 1.20V keeps power draw low during normal workloads. The unbuffered design adds no active components that would increase heat output. With no onboard ECC or registered circuitry the module runs quietly within typical desktop thermal limits.

Questions about this item

Will this module fit my Dell desktop that uses part number AB371020?

Yes — the module is listed as a compatible equivalent for Dell part numbers AB371020 and SNP36FTXC/4G, and it uses the standard 288-pin DDR4 DIMM form factor.

Can I add this 4GB stick to an existing 8GB DDR4 3200 kit?

It will work if your motherboard supports mixed capacities; both modules will run at 3200 MHz with CL22 timings at 1.20 V, but for dual-channel performance a matched pair is recommended.

Does this RAM require any special BIOS setting or voltage adjustment?

No — it operates at the standard DDR4 voltage of 1.20 V and uses the JEDEC-standard CL22 timing, so it should run automatically without manual configuration.
