Corsair Vengeance DDR5 4800MT/s CL40 - 16GB (1x16GB)

The Corsair Vengeance DDR5 4800MT/s CL40 is the baseline DDR5 kit in Corsair's Vengeance line, running at the DDR5 JEDEC standard speed of 4800MT/s. It fits platforms that need DDR5 but where you aren't planning to run XMP profiles or push the memory controller.

Specs and Performance

Timings are 40-40-40-77 at 1.10V, which is the JEDEC specification voltage. There's no overclocked XMP profile needed to hit 4800MT/s; this is the native DDR5 operating point. The kit uses a 288-pin UDIMM form factor with an aluminum heatspreader.

Available kit sizes include 16GB (1x16GB), 32GB (2x16GB), 48GB (2x24GB), 64GB (2x32GB), and up to 128GB configurations. That covers most desktop builds, including mini-ITX systems with dual-channel setups.

The real-world latency at CL40 / 4800MT/s works out to roughly 16.7ns, which is noticeably worse than higher-speed DDR5 kits running tighter timings. For latency-sensitive workloads, that gap is measurable.

Limitations

This kit has no XMP profile to push beyond 4800MT/s, and that's the point of it. If your board supports DDR5 and you want to run stock with no BIOS tuning, this works. But most Z690, Z790, and Z890 boards can easily run faster DDR5 kits with XMP enabled, so you're leaving bandwidth on the table.

Non-ECC and unbuffered, so it's not usable in platforms that require registered DIMMs or ECC, such as TrueNAS builds on server-class motherboards.

Best for: Systems where DDR5 is required by the platform but you want the simplest, lowest-voltage configuration with no BIOS profile tuning.

Avoid if: You're building for performance or have an AMD Ryzen AM5 platform. Spend slightly more for a 6000MT/s kit and you'll get meaningfully better performance.
