Corsair CMK64GX5M2B6000C30 64GB Review

Want 64GB of DDR5 with genuinely tight timings instead of a loose CL40 kit? The Corsair CMK64GX5M2B6000C30 is a matched 2x32GB Vengeance kit at DDR5-6000 CL30.

Performance

10.0ns true latency is one of the best results in this catalog at any capacity, and it's a clear step up from Corsair's own CMK64GX5M2B6000C40 kit (13.3ns) at the identical 6000MT/s speed and 64GB capacity, same speed, tighter timing, better real-world latency.

Comparison to Alternatives

This trades blows with Kingston FURY Renegade-tier 64GB DDR5-6000 CL30 kits on paper spec; the practical difference usually comes down to price and which brand's warranty terms you prefer.
