Redline is Mushkin's long-running DDR4 desktop line, sold here as a straightforward two-capacity family at one speed and timing. It's the kind of kit aimed at filling out a dual-channel pair without variants to sort through.
This kit is 2×16GB, 32GB total, rated 3200 MT/s CL22. Since both capacities in this family share the same 3200 MT/s and CL22, comparing listings is mostly a question of how much DDR4 the build needs rather than weighing different timing bins against each other.
Sold as UDIMM for standard desktop boards, it reaches its rated 3200 MT/s only with the XMP profile enabled in BIOS — the default JEDEC speed on any DDR4 module is lower than the number on the box.
