Detection system and method for memory bank installation failure

Abstract

The invention provides a detection system and method for a memory bank installation failure. The system comprises a memory bank and a corresponding memory slot, wherein the memory slot is welded on a motherboard; a ground signal pin I and a ground signal pin II at the two ends of the memory slot are connected with the anode end of a power supply respectively through a signal lamp and a resistance wire which are connected in series; other ground signal pins of the memory slot are connected together, and are connected with the cathode end of the power supply; the ground signal pins at the two ends of the memory slot are connected with a monitoring chip respectively. The system and the method are used for judging the fitting tightness of the memory bank and the memory slot. In case of a connection failure, the failure can be located qualitatively, quantitatively and vividly, and remote alarming can be performed.

Description

technical field [0001] The invention relates to a detection method and device in the field of computers, in particular to a detection system and method for installation faults of memory sticks. Background technique [0002] The memory stick is one of the most important basic components in the computer system, and it is a bridge to communicate with the CPU. All programs in the computer run in the memory, so whether the memory works normally or not, and the performance has a great impact on the computer. How to ensure the stability and high performance of the memory stick is a long-lasting research topic in the computer field. [0003] The tightness of the memory stick and the memory slot is the first step to ensure the normal operation of the memory stick, but in actual use, it often happens that the memory stick is not in good contact with the memory slot, or even the memory stick falls off. There are many factors that cause this situation. For example, the size of the mem...

Problems solved by technology

There are several defects in this method: for the subsequent use of memory sticks and memory slots, although the model remains the same, there will be differences between different batches of products, which will cause problems with the matching of memory sticks and memory slots; The vibration loosens the memory stick; it cannot avoid the poor contact caused by the aging of the gold finger or dust during the operation of the computer

The disadvantage of this method is that it is impossible to detect the lack of memory sticks. For example, two sticks of memory were inserted into the computer system, but one stick of memory was vibrated and separated from the memory slot during transportation, or it happened due to long-term use. One memory stick is isolated from the memory slot due to aging or too much dust. In this case, the BIOS can only detect one memory stick, and can only perform self-test on this one memory stick.

[0007] The above is the inspection method of conventional memory sticks used by motherboards developed by foreign X86CPUs. method
