Corsair CMK48GX5M2B6000Z30 48GB (2x24GB) DDR5 Desktop RAM Kit Review
Want more than 32GB but don't need a full 64GB kit? The Corsair CMK48GX5M2B6000Z30 is a 48GB (2x24GB) DDR5-6000 CL30 Vengeance kit that splits the difference.
24GB modules are Corsair's newer odd-capacity DIMMs built around higher-density dies, letting you land on 48GB total instead of jumping straight from 32GB to 64GB. CL30 at 6000MT/s is also a genuinely tight timing for this speed.
Performance
10.0ns true latency is excellent — CL30 at 6000MT/s is one of the tightest true-latency results in Corsair's DDR5 desktop lineup, on par with the CMK96GX5M2E6000C36 and CMK96GX5M4B6000C30 kits also using 6000/CL30-class timings in this catalog. Running as a 2-module kit at 6000MT/s also sits right at the AM5 1:1 fabric ratio.
Compatibility and Buying Advice
48GB is a sweet spot for buyers who've outgrown 32GB but don't want to pay for 64GB they won't use — heavy multitasking, large browser sessions, or light content work. If you specifically need 64GB, look at CMK64GX5M2B6000C40 instead.
