Embodiment Construction

[0032] Generally, a computer system designer will design a memory training codes in the basic input output system (hereinafter referred to as BIOS). During the initialization process of the computer system, the CPU will execute the memory adjustment program in the BIOS, and after the memory adjustment program is executed, the memory module can be successfully written and read.

[0033] The so-called memory adjustment procedure is to use the memory controller to control the respective time delays of the DQ signal and the DQS signal to achieve the alignment of the DQ signal and the DQS signal on the receiving end. Therefore, the memory adjustment program can write DQ signal adjustment program (write DQ), write DQS signal adjustment program (write DQS), read DQ signal adjustment program (read DQ), read DQS signal adjustment program (read DQS) .

[0034] Since the DQS signal and the DQ signal are aligned when the DRAM chip outputs them, the DQS signal and the DQ signal are not al...

Abstract

The invention discloses a memory adjustment result detection method and the computer system thereof. The method includes the steps: the computer system is started; the memory adjustment program of the BIOS in the computer system is executed; after the memory adjustment program is executed, the acquired a plurality of read time parameters and write time parameters are written into a non-volatile memory. The memory adjustment result detection method has the advantages that the acquired a plurality of read time parameters and write time parameters are written into the non-volatile memory during the startup process of the computer and the execution process of the BIOS.

Description

technical field [0001] The invention relates to a memory control method in a computer system, and in particular to a memory adjustment (training) result detection method and a computer system thereof. Background technique [0002] Generally, there is a memory controller on the motherboard of the computer system, and the memory controller can be designed in a north-bridge chip or a central processing unit (CPU). A memory module, such as a dual in-line memory module (DIMM for short), can be plugged into a memory module slot, such as a DIMM slot, on the motherboard. Therefore, the memory controller can transmit data with the memory module. [0003] Furthermore, the memory controller and the memory slots are soldered on the motherboard, and there are metal traces connecting the memory controller and the memory slots. In addition, the memory module also has a daughter board, and one side of the daughter board has gold fingers that can be inserted into the memory module slot. A...
