Corsair Vengeance LPX CMK32GX4M2E3200C16

CL16 at 3200MHz works out to 10ns of true latency, the standard mainstream DDR4 configuration. This is the E revision, which ships with 16-20-20-38 secondary timings, looser than the B and Z revisions of the same advertised DDR4-3200 CL16 kit, which run 16-18-18-36 instead.

The bigger practical constraint on this kit is capacity, not timing. 32GB is a comfortable, future-proof amount for gaming, multitasking, and light content work on a DDR4 platform, well beyond what a 16GB kit offers for the same core timings.

This is a DDR4 kit and fits DDR4 motherboards only; it will not install in an AM5 or DDR5 Intel board. On Intel boards, enable XMP 2.0 in BIOS to reach 3200MHz. On AMD boards the same profile is normally labelled DOCP or AMP, since XMP is an Intel standard AMD boards read through their own implementation. AMD EXPO does not apply here, as EXPO is a DDR5-only standard.

DDR4-3200 is the recommended speed for Ryzen 3000 and 5000 series, keeping the memory controller running 1:1 with the infinity fabric at 1600MHz. Check your motherboard's memory QVL before buying, particularly if running all four DIMM slots at full 32GB-per-kit capacity.

This is a two-module kit filling two slots, leaving two free on a standard four-slot ATX board for future expansion. Two sticks is the configuration DDR4 memory controllers handle most reliably, and a two-stick kit holds its rated speed more consistently than the same total capacity spread across four modules.

16GB DDR4 modules at this speed are commonly dual-rank. Corsair has changed IC suppliers across revisions of the Vengeance LPX line, so rank and die source are not guaranteed from the model number alone. Do not plan to buy a second identical kit later to reach 64GB; even two kits sharing the same part number bought at different times can be built on different dies, and mixing them is a common cause of boot failures and instability. Buy the full capacity needed in one matched kit.

The Vengeance LPX heat spreader is low-profile by design, standing 33.5mm tall specifically to clear large tower air coolers and fit small form factor builds where standard-height memory would not. There is no RGB lighting on this line; the heat spreader is a plain anodized aluminum finish, available here in black alongside white, blue, and red options elsewhere in the range.

Underneath the heat spreader the build is standard Corsair: an eight-layer PCB for signal integrity and hand-screened memory ICs, 288-pin construction, and a limited lifetime warranty.

Out of the box this kit boots at a JEDEC baseline of 2133MHz. It does not run at 3200MHz until the XMP profile is enabled. Enter BIOS, select XMP on Intel or DOCP on AMD, choose Profile 1, save and reboot. Confirm in CPU-Z that the reported frequency is 1600MHz, which is DDR4-3200 shown as its base clock.

Beyond XMP, manual tuning on this kit is a gamble. Corsair does not disclose the memory ICs used, and they vary between production runs, so overclocking headroom is not predictable from the part number. Buyers who specifically want to tune timings manually should choose a kit binned and sold for a known die instead.

The closest sibling is this same kit at 16GB (2x8GB) instead of 32GB, at the same 3200MHz CL16 E-revision timings, the right choice for a build that does not need the extra capacity. The Vengeance RGB PRO line at the same speed and capacity adds per-module RGB lighting in a taller, roughly 51mm heat spreader, at a real price premium and a real clearance trade-off under large air coolers.

Within the LPX line itself, some 3200MHz CL16 listings ship on the tighter B or Z revision at 16-18-18-36 instead of this E revision's 16-20-20-38; the difference is small enough that it should not drive the purchase on its own, but it is worth comparing prices between listings if both revisions are available.

DDR4 builds needing a genuine 32GB upgrade without RGB. This is the low-profile, cooler-friendly capacity step up from the 16GB LPX kit.

Ryzen AM4 builds running 3200 at 1:1 fabric. The platform-recommended DDR4 speed for this generation.

Small form factor and large air-cooler builds. The low-profile heat spreader clears hardware that taller RGB modules cannot.

Not for new 2026 builds, which should be DDR5.

Not for memory tuners and manual timing overclockers, given the undisclosed and variable ICs behind this part number.

Not for anyone planning to mix this kit with RAM they already own.
