SDRAM Burst Len

Common Options : 4, 8

Quick Review

This BIOS feature allows you to control the length of a burst transaction.

When this feature is set to 4, a burst transaction can only comprise of up to four reads or four writes.

When this feature is set to 8, a burst transaction can only comprise of up to eight reads or eight writes.

As the initial CAS latency is fixed for each burst transaction, a longer burst transaction will allow more data to be read or written for less delay than a shorter burst transaction. Therefore, a burst length of 8 will be faster than a burst length of 4.

Therefore, it is recommended that you select the longer burst length of 8 for better performance.
