A-Tech 8GB DDR4 3200MHz Desktop Memory

This A-Tech module provides 8GB of DDR4 memory for desktop computers. It operates at 3200MHz with a PC4-25600 rating and runs at the standard 1.20V voltage. The unbuffered, non-ECC DIMM is designed as a compatible replacement for the Samsung M378A1G44AB0-CWE part.

DDR4 288-Pin DIMM Interface Limits

The module uses the standard 288-pin DDR4 DIMM form factor, so it only fits motherboards with matching slots. Systems that require registered or ECC memory cannot use this unbuffered stick. Maximum speed is set by the platform's memory controller and may run below the tested 3200MHz frequency.

Single-Rank 1Rx16 Organisation

The memory is organised as a single-rank 1Rx16 configuration, which determines how the memory controller addresses the chips. Builders populating multiple slots should check their motherboard's qualified vendor list for rank limits. This specification decides whether the module works in a specific multi-channel setup.

Questions about this item

Should I pick the 8GB 1Rx16 module or look for a different capacity?

This listing is a single 8 GB DDR4 3200 MHz DIMM in a 1Rx16 layout. If your board has free slots you can add more identical modules later to reach the capacity you need.

What does the 3200 MHz rating actually deliver in my desktop?

The module runs at 3200 MT/s at the standard 1.2 V DDR4 voltage, giving a peak bandwidth of PC4-25600. Real-world throughput depends on your CPU memory controller and whether the board can run the XMP or JEDEC profile at that speed.

Will the 288-pin DDR4 DIMM fit and run at 3200 MHz on my motherboard?

The stick uses the standard 288-pin DDR4 DIMM form factor and is rated for 3200 MHz (PC4-25600) at 1.2 V. Your motherboard must support DDR4 and the 3200 MT/s data rate; otherwise it will down-clock to the highest speed the board allows.
