APACER DDR4-3200 CL22 UDIMM 32GB RAM module (1x32GB) AU32GGB32CSBBGH

APACER DDR4-3200 CL22 UDIMM 32GB RAM module (1x32GB) is a single unbuffered DIMM designed for desktop systems that support DDR4 memory. Operating at 3200 MT/s with CAS latency CL22, this 32GB stick delivers a large single-module capacity intended for memory upgrades, multitasking, content creation and heavier applications where increased RAM reduces swapping and improves responsiveness. The module follows standard UDIMM form factor for consumer motherboards and is suitable for systems that accept non-ECC DDR4 modules.

Advantages

The 32GB capacity provides ample space for running multiple applications, virtual machines or large datasets without frequent memory bottlenecks. Running at DDR4-3200 frequency improves data throughput compared with lower-speed DDR4 modules, while the CL22 latency specification balances speed and stability across a wide range of consumer platforms. As a single-module upgrade, it enables simple installation and leaves additional memory slots free for future expansion.

Suitable for

• Desktop upgrades to increase available RAM for multitasking and productivity
• Content creation workflows such as photo editing, video editing and 3D modeling
• Running virtual machines or containerized development environments on a single workstation
• Gaming systems where high memory capacity improves background application handling

When it may not be suitable

This UDIMM module is not suitable for motherboards that require ECC or registered/buffered memory, such as some server or workstation platforms. Systems limited to DDR3 or other memory generations will not be compatible. Additionally, dual-channel performance benefits require a matched pair in some configurations, so a single-module installation may not achieve maximum theoretical bandwidth compared with matched dual modules.

Key specifications

• Memory type: DDR4 UDIMM (unbuffered)
• Capacity: 32 GB (single module)
• Speed: 3200 MT/s (DDR4-3200)
• CAS latency: CL22
• Form factor: 288-pin DIMM for standard desktop motherboards
• Error correction: non-ECC

How to use

Power down the desktop and disconnect the power cable before installing the RAM module. Open the case to access the DIMM slots and refer to the motherboard manual to identify the recommended slot for single-module installations. Align the module with the 288-pin slot notch and press firmly and evenly until the retaining clips snap into place. After installation, reconnect power and boot the system; check BIOS/UEFI to confirm the module is detected and that the memory frequency and timing settings match the DDR4-3200 specification or are configured via XMP/DOCP if supported by the motherboard.

What to consider before purchase

• Check motherboard compatibility for DDR4 UDIMM and support for 32 GB single-module capacity
• Verify whether your system requires ECC or registered memory (this module is non-ECC, unbuffered)
• Confirm available DIMM slots and whether you plan to use single- or dual-module configurations for optimal performance
• Ensure your CPU and motherboard support DDR4-3200 speeds or be prepared to run at a lower supported frequency

Usage recommendations

For balanced performance, pair identical modules if you need dual-channel operation. When installing a single 32GB module, set BIOS/UEFI memory profiles if available to enable the intended 3200 MT/s speed and review system stability after changing memory settings.
