¹ Densities are defined by JEDEC for the life of the DDR5 generation of memory.
² Testing was conducted using a hardware configuration featuring an AMD X870 chipset motherboard, and a Ryzen 9 9800X3D processor. Performance comparisons based on Crucial DDR5 5600 memory modules versus Crucial DDR5 Pro Overclocking 6400MT/s CL32 with AMD Expo enabled. Actual results may vary.
³ Crucial DDR5 Pro OC Gaming memory modules (UDIMMs) can reach rated speeds with Intel XMP 3.0 or most AMD EXPO^TM turned on in the UEFI/BIOS settings. Altering clock frequency or voltage beyond rated speeds of 6,400MT/s and timing of 32-40-40-103 at 1.35V may result in damage to computer components and will void your Crucial warranty. Micron disclaims all liability for such damage. 
⁴ Comparing the true memory latency of Crucial Pro DRAM: OC Gaming Edition of 10ns for 6,400MT/s CL32 to the true memory latency of Crucial Pro DRAM Plug-and-Play edition of 16ns for 6,000MT/s CL48. 10ns is 37.5% lower than 16ns of true memory latency. 
⁵ Crucial DDR5 Pro Memory modules (UDIMMs) can only be installed in desktops/workstations built to support DDR5 DRAM, such as 13th and 14th Gen Intel® Core™ and AMD Ryzen™ 9000 Series desktop processors. 
⁶ Limited lifetime warranty valid everywhere except Austria, Belgium, France and Germany, where warranty is valid for ten years from the date of purchase. DRAM components and modules are rated for 6,400MT/s 32-40-40-103 at 1.35V. Altering the module’s clock frequency, speed, timings or voltage beyond its specifications may damage system components and will void its warranty. Micron disclaims all liability for damage caused by overclocked beyond 6,400MT/s 32-40-40-103 at 1.35V. Please check your CPU and motherboard manuals for their warranty information when overclocked. 
⁷ Under memory-intensive workloads, DDR5 can deliver up to two times the bandwidth of DDR4, per an internal simulation of dual-ranked x8 modules in client platforms.
