Frequently Asked Questions

What motherboards are compatible with this memory?

The Corsair Dominator Titanium RGB DDR5 64GB (2x32GB) 6600MT/s DIMM Intel XMP — CMP64GX5M2X6600C32 requires a DDR5-compatible motherboard. This kit uses Intel XMP profiles, optimized for Intel LGA 1851 (Z890, B860) and LGA 1700 (Z790, B760) platforms. It is also physically compatible with AMD AM5 DDR5 boards. Enable XMP in BIOS to run at rated speed.

Do I need to enable Intel XMP in BIOS?

Yes. Out of the box, DDR5 memory runs at JEDEC default speed (typically 4800 MT/s). To achieve the rated 6,600 MT/s with CL32-40-40-84 timings, enable Intel XMP 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 Dominator Titanium RGB DDR5 64GB (2x32GB) 6600MT/s DIMM Intel XMP — CMP64GX5M2X6600C32 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 Dominator Titanium RGB DDR5 64GB (2x32GB) 6600MT/s DIMM Intel XMP — CMP64GX5M2X6600C32 features a DHX heatspreader with RGB lighting. The module height is 56.0 mm. Check clearance with your CPU cooler — tall heatspreaders may interfere with large tower coolers.

What warranty does this memory come with?

The Corsair Dominator Titanium RGB DDR5 64GB (2x32GB) 6600MT/s DIMM Intel XMP — CMP64GX5M2X6600C32 comes with a Limited Lifetime warranty from Corsair.
