您可以在内存模块背面看到一系列四个数字表示的内存时序: 尝试将tCL、tRCD、tRP和tRAS各降低1。重新启动您的PC并检查其性能是否稳定。确保不要将时序降低过多,否则会遇到性能问题。 增加电压以获得更稳定性 在超频时,您可能希望增加DRAM电压以提高内存的稳定性,特别是在进行相对高的超频时。 我们建议在增加DRAM电压...
Precharge: Used to activate/deactivate a row in the selected bank before it can be used for read/write operation. These timings are specified are in the following order :tCL-tRCD-tRP-tRASand as you have guessed‘t’stands for time. NOTE:All latencies are in terms of clock cycles and act...
tRAS is the minimum number of cycles between a row being opened and the precharge command being issued to close it again. This has historically been around the value of tRCD + tCL. For current DDR5 modules, however, it appears to be set nearer tRCD +(2x tCL). It’s unclear if this ...
Row Address to Column Address Delay (tRCD) – The second number denotes the minimum number of clock cycles it will take to open a row (again, on that giant spreadsheet) and access the required column. Remember, unlike tCL, tRCD isn’t an exact number but is the maximum delay. ...
occasionally there can be issues with memory stability scaling inversely with voltage, so it's best to start low and work your way up), set the SOC voltage to 1.15V, and set the memory timings to 20-30-30-50 for tCL-tRCD-tRP-tRAS respectively (set tRCDRD and tRCDWR to the tRCD ...

For example, the amount of time it takes to access a new memory cell (after accessing a previous one) is tRAS (for a successful retrieval of data in the previous cell) + tRP (to switch to a different row) + tRCD (delay to access a column) + tCL (result from the cell itself). ...
