8GB DDR4 2400MHz module for desktop upgrades

This single 8GB DIMM adds memory to desktops using DDR4 slots. It runs at 2400MHz with CL17 latency and 1.2V power draw. The unbuffered, non-ECC design suits standard consumer motherboards and OEM systems.

DDR4 2400 interface limits

The DDR4-2400 standard caps transfer rates at 2400 MT/s and peak bandwidth at PC4-19200. Speeds start at 2133 MT/s, so this module operates at the upper JEDEC rate for this generation. Intel XMP 2.0 profiles are supported where the platform allows.

Capacity headroom for everyday workloads

Eight gigabytes handles web browsing, office suites and light multitasking without paging. Heavier tasks such as video editing, large datasets or modern gaming with high texture settings will exceed this capacity and require additional modules.

Questions about this item

Should I pick a single 8GB stick or two 4GB sticks for dual channel?

This module is a single 8GB DIMM. Adding a second identical stick will enable dual-channel operation on supported motherboards.

What does the 2400MHz rating mean for actual system speed?

The module runs at 2400 MT/s with CL17 latency at 1.2V. Real-world throughput depends on the memory controller and whether XMP 2.0 is enabled in BIOS.

Is this DDR4 stick limited to 2133MHz on older chipsets?

The DIMM is rated for DDR4-2400 (PC4-19200). If the platform only supports 2133 MT/s, the module will down-clock automatically to that speed.
