Frequently Asked Questions

What motherboards are compatible with this memory?

The Corsair Vengeance RGB DDR5 32GB (2x16GB) 6400MT/s DIMM AMD EXPO — CMH32GX5M2B6400Z32 requires a DDR5-compatible motherboard. This kit uses AMD EXPO profiles, optimized for AMD AM5 platforms (X870E, X870, X670E, X670, B850, B650 chipsets). While physically compatible with Intel DDR5 boards, the EXPO profile may not activate on Intel — look for Intel XMP variants for Intel platforms. The memory will still work at JEDEC default speeds on any DDR5 board.

Do I need to enable AMD EXPO in BIOS?

Yes. Out of the box, DDR5 memory runs at JEDEC default speed (typically 4800 MT/s). To achieve the rated 6,400 MT/s with CL32-40-40-84 timings, enable AMD EXPO in your motherboard BIOS. This is a one-click setting in the memory overclocking section.

Does this kit run in dual-channel mode?

Yes, the Corsair Vengeance RGB DDR5 32GB (2x16GB) 6400MT/s DIMM AMD EXPO — CMH32GX5M2B6400Z32 includes 2 modules which enable dual-channel mode when installed in the correct DIMM slots (typically A2+B2 or slots 2+4). Dual-channel doubles memory bandwidth compared to single-channel configuration. Check your motherboard manual for optimal slot placement.

Does this memory have a heatspreader?

Yes, the Corsair Vengeance RGB DDR5 32GB (2x16GB) 6400MT/s DIMM AMD EXPO — CMH32GX5M2B6400Z32 features a Aluminum heatspreader with RGB lighting. The module height is 44.2 mm. Check clearance with your CPU cooler — tall heatspreaders may interfere with large tower coolers.

What warranty does this memory come with?

The Corsair Vengeance RGB DDR5 32GB (2x16GB) 6400MT/s DIMM AMD EXPO — CMH32GX5M2B6400Z32 comes with a Limited Lifetime warranty from Corsair.
