Overview
Corsair's Vengeance LPX kit pairs two 8GB DDR4 modules for 16GB total, rated up to 3200MHz, with a low-profile 34mm heatspreader for tight builds.
The rated 3200MHz speed depends on enabling XMP or manually overclocking in BIOS; at stock JEDEC settings without that step, the modules run slower. The low 34mm height is the practical selling point for anyone using a large CPU air cooler that would otherwise overhang taller memory modules.
- 16GB (2x8GB) DDR4 kit
- Up to 3200MHz via XMP
- CL16-20-20-38 timings at 1.35V
- 34mm low-profile heatspreader
Who it's for
Fits a desktop builder on an Intel or AMD DDR4 platform who wants matched, tested memory rather than piecing together mismatched sticks. Less relevant for anyone already on DDR5, since this kit is DDR4 only.
Pros and cons
- 16GB (2x8GB) matched kit avoids mixing mismatched memory
- 34mm low-profile height clears large CPU coolers
- XMP profile included for one-step overclocking
- Broad compatibility with current Intel and AMD DDR4 boards
- Rated 3200MHz speed requires enabling XMP or manual BIOS tuning
- DDR4 only, not usable on DDR5 platforms
Performance notes
Rated speed and CL16-20-20-38 timings at 1.35V are reached via the included XMP profile; Corsair notes actual speed depends on the motherboard and CPU, and requires overclocking or BIOS adjustment to hit the rated 3200MHz. The aluminum heatspreader dissipates heat during that overclocked operation, helping the modules stay stable at higher clocks.

Frequently asked questions
Do I need to do anything to reach 3200MHz on this Corsair kit?
Yes, Corsair states the rated speed requires enabling the included XMP profile or manual BIOS overclocking; it will not run at 3200MHz on default JEDEC settings.
Will this low-profile kit clear a tall CPU air cooler?
Yes, the 34mm heatspreader height is specifically meant to fit under large air coolers in small-form-factor builds.
Is this kit compatible with DDR5 motherboards?
No, this is a DDR4 kit and will not work in a DDR5-only motherboard.
