Riser Card with Adjustable Time Delay Parameters

Abstract

The invention provides a time delay parameter adjustable adapter card. The time delay parameter adjustable adapter card comprises an adapter card body. A first contact, a second contact, a third contact, a fourth contact, a fifth contact, a sixth contact, a control unit, a data signal delay unit and a data alignment signal delay unit are arranged on the adapter card body. The first contact is connected with the second contact. The second contact is connected with the control unit. The control unit is connected with the data signal delay unit and the data alignment signal delay unit. The data signal delay unit is connected with the third contact and the fourth contact. The data alignment signal delay unit is connected with the fifth contact and the sixth contact. The first contact, the third contact and the fifth contact are correspondingly connected with an address command pin, a data pin and a data alignment pin of an internal storage module. The second contact, the fourth contact and the sixth contact are correspondingly connected with an address command pin, a data pin and a data alignment pin of a main board. According to the time delay parameter adjustable adapter card, problems can be located by adjusting delay time when the method for changing configurations of the main board lacks.

Description

[0001] 【Technical field】 [0002] The invention relates to an adapter card, in particular to an adapter card with adjustable time delay parameters for testing memory modules on a computer main board. [0003] 【Background technique】 [0004] see figure 1 with figure 2 As shown, the application test of the memory module is generally carried out on the computer motherboard. If the computer motherboard cannot be started when a certain memory module is applied, it is characterized as a "compatibility problem" of the memory module or the motherboard. . "Compatibility problems" are generally caused by the mismatch of time parameters when the computer motherboard is operating the memory module. Since the computer motherboard cannot be started, it is not possible to find out the cause of the problem by measuring the signal. The existing method is to apply a problematic memory module on a computer motherboard to other computer motherboards of different models and manufacturers. If ...

AI Technical Summary

Problems solved by technology

If it can be started on some computer motherboards, it is considered that the memory module has a compatibility problem on the computer motherboard that cannot be started; if it cannot be started on all computer motherboards, it is considered that the memory module itself has a problem

Because there is no method to change the time parameters of the memory controller on the computer motherboard, the reason why the system cannot be started cannot be determined by adjusting the time parameters of the memory controller
