What this module is and who it suits

This 8GB DDR4 3200MHz CL22 DIMM replaces Samsung M378A1G44BB0-CWE and M378A1G44CB0-CWE modules in desktop systems. It delivers 3200MT/s speed at standard 1.20V without ECC or buffering. Builders upgrading compatible Samsung platforms or adding capacity to a DDR4 board will find a direct-fit replacement.

How it fits into a desktop build

The unbuffered 288-pin DIMM slots into any standard DDR4 desktop motherboard slot that accepts 1Rx16 organisation. No heat spreader means low-profile clearance for compact coolers or small-form-factor cases. Single-rank layout leaves additional slots free for future expansion up to the board’s supported maximum.

What the bundled assurance changes

Every module undergoes A-Tech quality-assurance testing before shipment so it meets the specified 3200MHz CL22 timing out of the box. Lifetime warranty coverage and US-based technical support provide long-term replacement protection and troubleshooting help if compatibility questions arise after installation.

Questions about this item

Will the CL22 latency become the bottleneck during long rendering jobs?

CL22 is the rated CAS latency at 3200 MHz; sustained workloads run at this timing.

Does the module run hot or draw extra power during all-day operation?

Rated at 1.20 V with no heat spreader; power draw stays at standard DDR4 levels.

My motherboard has 288-pin DDR4 slots — is that the only requirement?

Yes, it needs a 288-pin DDR4 DIMM slot and a board that accepts non-ECC unbuffered memory.
