Read-Around-Write

Common Options : Enabled, Disabled

Quick Review

This BIOS feature allows the processor to execute read commands out of order, as if they are independent from the write commands. It does this by using a Read-Around-Write buffer.

If this BIOS feature is enabled, all processor writes to memory are first accumulated in that buffer. This allows the processor to execute read commands without waiting for the write commands to be completed.

The buffer will then combine the writes and write them to memory as burst transfers. This reduces the number of writes to memory and boosts the processor's write performance.

If this BIOS feature is disabled, the processor writes directly to the memory controller. This reduces the processor's read performance.

Therefore, it is highly recommended that you enable this feature for better processor read and write performance.
