Corsair CMT64GX5M2B6000Z30 64GB Review

The Corsair CMT64GX5M2B6000Z30 is a 64GB (2x32GB) DDR5-6000 CL30 kit from Corsair's Dominator Platinum RGB line.

This is one of the better-balanced 64GB Dominator Platinum RGB kits: 6000MT/s CL30 hits AM5's 1:1 fabric sweet spot with a tight 10.0ns true latency, better than the CL36-CL40 versions of this same 64GB kit that Corsair also sells.

Performance

6000MT/s CL30 computes to 10.0ns true latency, the tightest timing available in Corsair's 64GB (2x32GB) Dominator Platinum RGB lineup at this speed, alongside a full 64GB of capacity.

Compatibility

6000MT/s CL30 is the AM5 sweet spot and also runs cleanly on Intel Z-series boards.

Comparison to Alternatives

Corsair also sells this same 64GB (2x32GB) 6000MT/s kit at CL40 (CMT64GX5M2B6000C40) for less money, worth comparing the price gap against the roughly 3ns of latency this CL30 version saves.
