DRAM PreChrg to Act CMD
Common Options : 2T, 3T, 4T
Like SDRAM Trp Timing Value, this BIOS feature controls the RAS precharge time (tRP). This constitutes the time it takes for the Precharge command to complete and the row to be available for activation. Hence, the name DRAM PreChrg to Act CMD, which is short for DRAM Precharge Command to Activate Command.
If the RAS precharge time is too long, it will reduce performance by delaying all row activations. Reducing the precharge time to 2T improves performance by allowing a new row to be activated earlier.
However, the short precharge time of 2T may be insufficient for some memory modules. In such cases, the active row may lose its contents before they can be returned to the memory bank and the row deactivated. This may cause data loss or corruption when the memory controller attempts to read from the active row or write to it.
Therefore, it is recommended that you reduce the RAS precharge time to 2T for better performance but increase it to 3T or 4T if you experience system stability issues after reducing the precharge time.
