Vengeance DDR5 5200 Dual-Channel Kit

This Corsair Vengeance kit provides 16GB of DDR5 memory as two 8GB modules running at 5200 MT/s with CL40 timings. The modules operate at 1.25V and include both AMD EXPO and Intel XMP 3.0 profiles for automatic configuration. A grey aluminium heatspreader covers each 288-pin DIMM.

AMD 600-series and Intel 600-series platforms

The kit targets AMD 600-series and 800-series chipsets plus Intel 600-series platforms for gaming or high-performance desktop builds. Systems that require lower voltage, tighter latency or higher frequency kits should evaluate alternative modules. Compatibility depends on the motherboard Qualified Vendor List.

DDR5 5200 CL40 at 1.25V

The decisive specification is the 5200 MT/s data rate combined with CL40 latency at 1.25V. This balance of speed, timing and voltage determines whether the memory matches the CPU memory-controller capabilities and the motherboard trace topology for stable operation.

Questions about this item

Will this kit run at 5200 MT/s on my AMD B650 motherboard?

Yes, the kit carries an AMD EXPO profile validated for AMD 600- and 800-series chipsets including B650, so enabling EXPO in the BIOS sets the rated speed and CL40 timings automatically.

Does the 1.25 V operating voltage require manual BIOS changes on an Intel Z790 board?

No, the modules also include an Intel XMP 3.0 profile; activating XMP in the BIOS applies the 5200 MT/s speed, CL40 timings and 1.25 V voltage without manual adjustment.

Will the aluminum heatspreader clear a large CPU air cooler?

The low-profile heatspreader is designed for wide compatibility with popular air coolers, but you should verify the cooler’s specified RAM clearance against the module height before purchasing.
