WebJun 22, 2024 · Generally speaking, CPU SA, CPU IO, and memory voltage all affect memory overclocking. If it's not stable with the Memory Try It! profiles, you can try to increase CPU SA, CPU IO, or memory voltage gradually to see if it's helpful or try with loose main timings. The Memory Force of DDR4-4600. It's stable with DDR4-4500 CL19-21-21. Memory timings or RAM timings describe the timing information of a memory module. Due to the inherent qualities of VLSI and microelectronics, memory chips require time to fully execute commands. Executing commands too quickly will result in data corruption and results in system instability.
