32GB DDR5 4800MHz DIMM

This A-Tech module delivers 32GB of DDR5 memory at 4800MHz with CL40 latency and 1.10V operation. The 288-pin unbuffered DIMM uses major-brand chips and is validated as a replacement for Dell part numbers SNPWMMC0C/32G and AB883075. It targets desktop systems that require non-ECC UDIMM memory.

Suits standard desktop upgrades

The module fits AMD and Intel platforms that support DDR5 4800MHz unbuffered DIMMs. It is not intended for systems that require ECC or registered memory, nor for laptops or servers using SO-DIMM or RDIMM form factors. Verify your motherboard's qualified vendor list before purchasing.

Handles everyday multitasking

The 32GB capacity provides ample headroom for office suites, web browsing with many tabs, and light content creation. Workloads such as virtualisation, large dataset processing, or high-end gaming with heavy texture streaming may exceed the single-module bandwidth and capacity headroom.

Questions about this item

Does my desktop motherboard need a DDR5-compatible 288-pin DIMM slot for this module?

Yes, this is a DDR5 4800MHz PC5-38400 DIMM with 288 pins and requires a motherboard that supports DDR5 memory.

Can I run this 32GB CL40 stick alongside my existing DDR5 4800MHz memory?

It will operate at 4800MHz 1.10V CL40; mixing modules of the same speed and voltage usually works, but the system will run all sticks at the slowest common timings.

How do I confirm the module is running at 4800MHz CL40 after installation?

Check the memory speed and latency in BIOS or with a tool such as CPU-Z; it should report 4800MHz and CL40 at 1.10V.
