Corsair CMH64GX5M2B6000Z28 64GB Review
Looking for a 64GB DDR5-6000 RGB kit with genuinely tight CL28 timings? The Corsair CMH64GX5M2B6000Z28 is a matched 2x32GB Vengeance RGB kit at exactly that spec.
CL28 at 6000MT/s is about as tight as timings get at this speed, and true latency of 9.3ns beats most 64GB kits in this catalog, RGB or not, you're not giving up performance for the lighting here.
Performance
9.3ns true latency is excellent, beating Corsair's own non-RGB CMK64GX5M2B6000C30 kit (10.0ns) at the same 6000MT/s and 64GB capacity despite the RGB lighting hardware. AMD EXPO is confirmed by Corsair for this kit, so Ryzen builds get one-click tuning.
Comparison to Alternatives
Against Corsair's own non-RGB CMK64GX5M2B6000C30 (also CL30, not CL28), this Z28 RGB kit actually wins on raw latency in addition to offering the lighting, a rare case where the RGB kit isn't a pure premium-for-looks purchase.
