CORSAIR VENGEANCE DDR5 RAM 64GB (2x32GB) 5200MHz CL40-40-40-77 1.25V Intel XMP Desktop Computer Memory - Black (CMK64GX5M2B5200C40)
Bottom line: The CORSAIR VENGEANCE DDR5 RAM 64GB ($994.99 on Amazon as of 2026-10-21 10:15 UTC, orderable but not in stock): 64GB in just two DIMMs, leaving two slots free for a later upgrade; main trade-off: CL40-40-40-77 is loose timing; faster CL36 kits exist at 5200MHz.

Pros & Cons
Pros
- ✓ 64GB in just two DIMMs, leaving two slots free for a later upgrade
- ✓ Onboard PMIC voltage regulation for finer overclock control than DDR4
- ✓ Intel XMP 3.0 with per-app profiles saved through CORSAIR iCUE
- ✓ Compact heatspreader height clears most tall air coolers
Cons
- ✗ CL40-40-40-77 is loose timing; faster CL36 kits exist at 5200MHz
- ✗ 5200MHz is entry-level DDR5, below 6000-7200MHz enthusiast kits
- ✗ Tuned for Intel XMP, so AMD EXPO boards may need manual timing
- ✗ No RGB lighting, unlike the VENGEANCE RGB DDR5 line
Manufacturer description
CORSAIR VENGEANCE DDR5 64GB (2x32GB) gives you serious headroom for multi-core workloads without stepping up to a four-DIMM configuration. The two 32GB modules use 288-pin DDR5 DIMMs with onboard voltage regulation, which moves power management off the motherboard and onto the module itself for finer, more stable overclocking than DDR4 kits allowed. Intel XMP 3.0 support lets you save custom profiles through CORSAIR iCUE and switch them per application, so a rendering profile and a gaming profile can live on the same sticks. iCUE also surfaces real-time frequency readings and voltage control…
SpecPicks Verdict
SpecPicks scored CORSAIR VENGEANCE DDR5 RAM 64GB (2x32GB) 5200MHz CL40-40-40-77 1.25V… using a rating × review-volume × price-fit model applied to published specs and reviews across the memory (ram) category. Compare with similarly-priced alternatives in the memory (ram) category before committing. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for memory (ram) of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Will this 64GB kit work in an AMD Ryzen build?
It is optimized for Intel motherboards and ships with Intel XMP 3.0 profiles rather than AMD EXPO. It can run on AMD boards, but you may need to set the 5200MHz CL40-40-40-77 timings and 1.25V manually. Check your motherboard's memory QVL first.
Is 5200MHz fast enough, or should I get a higher-speed kit?
5200MHz is the DDR5 baseline speed tier. For gaming and general productivity the difference against 6000MHz kits is small; for memory-bandwidth-heavy work like rendering or local AI inference, a faster kit helps more. Timings here are CL40-40-40-77.
Do I need CORSAIR iCUE software to use this memory?
No. The XMP 3.0 profile is enabled in BIOS and works without software. iCUE is optional and adds real-time frequency readings, onboard voltage regulation, and the ability to create and save custom XMP profiles per application.
Will the heatspreader fit under a large CPU air cooler?
CORSAIR lists this VENGEANCE DDR5 module as a compact form factor with a low-profile solid aluminum heatspreader, so clearance is better than tall RGB kits. Confirm the exact module height against your cooler's specification before buying.
Why is it 2x32GB instead of 4x16GB?
Two 32GB modules put less load on the memory controller than four sticks, which makes hitting rated speed easier on DDR5. It also leaves your other two DIMM slots open, though mixing kits later can affect stability.
