  • Key Specs
    • Type of Memory (RAM): DDR5
    • Form Factor: Desktop (The type of computer the memory is configured to fit in.)
    • Speed: 5600 megahertz
    • Latency: 46-45-45 (Refers to the amount of time between the moment a memory request is initiated and the moment the request is retrieved by a processor, commonly written as a series of 4 numbers, or timings. Each timing measures the performance of the module according to a specific parameter. Generally, the lower the numbers, the faster the RAM can respond to requests.)
    • CAS Latency: 46 (Column Address Strobe (CAS) Latency refers to the number of clock cycles (for synchronous DRAM) or nanoseconds (for asynchronous DRAM) between the moment an instruction or command is initiated and the moment the data result is available. Generally, the lower the numbers, the better.)

  • Speed
    • Memory Speed Rating: PC5-44800, PC5-44800 (The RAM's bandwidth rating. The numbers refer to generation and transfer speed and are typically separated with a hyphen. For example, PC3-12800 would indicate that the module is 3rd generation and has a theoretical bandwidth of 12,800 megabytes per second (MBs). The higher the second number, the faster the speed.)
    • Speed: 5600 megahertz
    • Latency: 46-45-45 (Refers to the amount of time between the moment a memory request is initiated and the moment the request is retrieved by a processor, commonly written as a series of 4 numbers, or timings. Each timing measures the performance of the module according to a specific parameter. Generally, the lower the numbers, the faster the RAM can respond to requests.)
    • CAS Latency: 46 (Column Address Strobe (CAS) Latency refers to the number of clock cycles (for synchronous DRAM) or nanoseconds (for asynchronous DRAM) between the moment an instruction or command is initiated and the moment the data result is available. Generally, the lower the numbers, the better.)
  • Features
    • Buffered or Registered: Unbuffered (Registered (buffered) memory modules are classified by the addition of a register between the memory controller and DRAM modules. When compared to conventional unbuffered (unregistered) memory, this type provides more stability with less electrical load on the controller, making it a common choice for use in robust applications, such as servers.)
    • Data Integrity Check: Non-ECC (Error-correcting code (ECC) memory helps to maintain data integrity within a computer system, protecting it from potential crashes as well as losses or changes to data due to undetected errors. Systems that use ECC have an additional chip on the RAM that acts as the error check.)
    • Memory Channels: Single (Multi-channel memory increases the rate of data transfer between the DRAM memory and memory controller by adding more channels of communication. The more channels, the more memory bandwidth.)
    • Lighting Type: None
    • Fan Included: false
    • Performance Profile(s): Intel XMP 3.0, AMD EXPO
  • Power
    • Voltage: 1.1 volts (Amount of power needed to support an electrical current.)

Disclaimers
  • Only DDR5-enabled CPUs/motherboards support DDR5 memory. Not compatible with DDR4 motherboards.
  • Crucial DDR5 desktop memory modules (UDIMMs) can reach rated speeds with Intel XMP 3.0 or AMD EXPOTM turned on in the UEFI/BIOS settings. Applicable for all Crucial DDR5 desktop memory (UDIMM) modules except Crucial DDR5-4800 desktop memory, which supports only Intel XMP 3.0. Based on published competitor specs for DDR5 memory as of August 2023.
  • Altering clock frequency or voltage beyond advertised speeds and timing (overclocking) may result in damage to computer components and will void your Crucial warranty. Micron disclaims any and all liability for such damage.
  • DDR5 speeds are comparable to extreme-performance DDR4 memory speeds and, at 4,800MT/s, at least 1.5x faster than maximum standard DDR4 speeds of 3,200MT/s.
  • Crucial DDR5 Pro Memory modules (UDIMMs) can only be installed in desktops/workstations built to support DDR5 DRAM, such as 12th and 13th Gen Intel Core and AMD Ryzen 7000 Series desktop processors.
  • DDR5 data rate of 6,000MT/s transfers 1.88x the DDR4 data rate of 3,200MT/s.
  • Under memory-intensive workloads, DDR5 can deliver up to 2x the bandwidth, per an internal simulation of dual ranked x8 modules in client platforms.
  • DDR5 modules (DIMMs) introduce voltage regulation on the module through a power management integrated circuit (PMIC), which enables better power regulation and reduces the scope of DRAM power delivery network (PDN) management on the motherboard for increased efficiency.
  • On-die ECC (ODECC) is a feature of the DDR5 component specification and should not be confused with the module-level ECC features on server and workstation RDIMMs, LRDIMMs, ECC UDIMMs and ECC. Crucial DDR5 Memory includes ODECC but does not include the additional components necessary for system level ECC.
  • Densities are defined by JEDEC for the life of the DDR5 generation of memory.
  • Limited lifetime warranty valid everywhere except Germany and France, where warranty is valid for ten years from the date of purchase.
  • Only DDR5-enabled CPUs/motherboards support DDR5 memory. Not compatible with DDR4 motherboards.
  • Crucial DDR5 desktop memory modules (UDIMMs) can reach rated speeds with Intel XMP 3.0 or AMD EXPOTM turned on in the UEFI/BIOS settings.

  • Rated 5 out of 5 stars

    Compatibility issue with the system maybe

    Listed Speed and Actual speed are different Actual speed was showing 4400MHz RAM is installed in the system

    Great deal. Great Quality.

    I bought two of these, for 256 gb of ram, they work great with the I9-14900k. Must have Windows 11 Pro to use all 256gb.
