Memory Generation Supported by the 7950X
The Ryzen 9 7950X CPU only supports DDR5 memory. Other generations of memory are incompatible.
The generation of memory (e.g., DDR3, DDR4, or DDR5) must match what is supported by your motherboard. Motherboards only support a single generation of memory.
Maximum Memory Speeds Supported by the 7950X
The maximum speed at which you can run PC memory depends on your CPU, motherboard, and the memory itself.
When using DDR5 memory, the Ryzen 9 7950X CPU officially supports effective memory speeds up to 5200 MHz (5200 MT/s). This maximum speed means that stock DDR5 performance will be maximized using DDR5-5200 memory.
When overclocking memory, you can exceed these stock speeds officially supported by CPUs. Motherboard specifications will indicate their supported overclocked-memory speeds.
RAM can also be underclocked to achieve compatibility. Underclocking can be used when you purchase memory that is faster than the maximum speed supported by the CPU or motherboard. However, precise underclocking also requires a motherboard that supports memory overclocking. Without this support, the memory may fall back to a slower speed than the maximum supported memory speed. To achieve the maximum memory speed without overclocking support, use the maximum speed supported by the motherboard and CPU.
By looking up a motherboard's specifications, you can verify whether it supports a particular speed. Additionally, the motherboard manufacturer's website will typically indicate which memory kits have been confirmed to be compatible.
Compare DDR5 speeds to the previous generation DDR4 speeds in the following table:
|Max UDIMM (Unbuffered) Capacity||32 GB||128 GB|
|Bandwidth||12800–25600 MB/s||38400–57600 MB/s|
|Transfer Rate||1600–3200 MT/s||4800–7200 MT/s|
|Base Frequency||800–1600 MHz||2400–3600 MHz|
|Effective Frequency||1600–3200 MHz||4800–7200 MHz|
|Voltage||1.2 V||1.1 V|
7950X ECC Memory Support
Most gaming and general-purpose desktop setups do not use ECC memory.
Error correction code (ECC) memory is a more expensive form of memory typically used for critical server and workstation use cases. The purpose of ECC memory is to detect and correct when a single bit in memory gets flipped unintentionally.
ECC memory will not work unless the motherboard and CPU support ECC.
AMD Ryzen 7000 series CPUs, including the 7950X, support ECC memory.
When desktop motherboards support ECC memory, it's typically limited to "unbuffered ECC" memory. Server motherboards may support "registered ECC" memory, which allows for additional memory modules.
Before Buying RAM
Before purchasing memory, review your motherboard specification to verify which speeds are supported. For example, if a DDR4 motherboard stated that it supports "DDR4 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200 / 3000," that would mean that it could support DDR4-3400, DDR4-3333, and DDR4-3300 with memory overclocking, and DDR4-3200 and DDR4-3000 at stock speeds. Motherboard specifications also indicate the maximum capacity per stick of RAM (DIMM) and across all slots.
