CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
DDR4 and DDR5 are different generations of double data rate synchronous dynamic RAM. DDR5 offers higher data rates (up to 6400 MT/s) and lower operating voltage (1.1 V) compared to DDR4 (up to 3200 MT/s and 1.2 V). They are not interchangeable; the motherboard and CPU must support the specific generation.
The required capacity depends on the operating system, applications, and workload. For general desktop use, 8–16 GB is common; for servers or heavy multitasking, 32–64 GB may be needed. Check the motherboard's maximum supported capacity and the CPU's memory controller limits.
CAS (Column Address Strobe) latency is the delay in clock cycles between the memory controller requesting data and the data being available. Lower latency means faster response. It is one of several timing parameters that affect performance, but it must be compatible with the system's supported timings.
Mixing modules may work, but the system will typically run at the speed of the slowest module and may not support dual-channel operation optimally. For best performance and stability, use identical modules from the same manufacturer and part number. Always verify compatibility with the motherboard.
