This week TechARP reveals the functions of the Digital Locked Loop (DLL) BIOS function, you can read about it
over here.
The Digital Locked Loop (DLL) aligns the data strobe signal (DQS) with the data signal (DQ) to ensure proper data transfer of DDR, DDR2 and DDR3 memory. However, it can be disabled to allow the memory chips to run beyond a fixed frequency range.
When enabled, the digital locked loop circuit (DLL) will operate normally, aligning the DQS signal with the DQ signal to ensure proper data transfer. However, the memory chips should operate within the fixed frequency range supported by the DLL.
When disabled, the digital locked loop circuit (DLL) will not align the DQS signal with the DQ signal. However, this allows you to run the memory chips beyond the fixed frequency range supported by the DLL.
