All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flowchart of a method for setting a memory parameter according to an embodiment of the application.
The method for setting the memory parameter is applied to a server system comprising a memory, and comprises the following steps:
step S1: and in the system starting stage, storing the preset initialization parameter value of the memory into a system parameter structure.
Specifically, the application presets the initialization parameter value of the memory. And in the system starting stage, acquiring a preset initialization parameter value of the memory, and then storing the preset initialization parameter value of the memory into a system parameter structure.
Step S2: and determining a target parameter setting strategy which is matched with the total error times in the last operation process of the internal memory system according to the preset error times and parameter setting strategy matching relation.
Specifically, the application presets the adaptation relation between the error times and the parameter setting strategies, namely, the parameter setting strategies which are respectively adapted are configured for different error times, so as to determine the target parameter setting strategy which is adapted to the total error times (which can be obtained by reporting errors according to the statistical memory ECC (Error Correcting Code, error checking and correcting)) in the last operation process of the system according to the preset adaptation relation between the error times and the parameter setting strategies in the current starting stage of the system.
Step S3: and updating the memory parameter values stored in the system parameter structure according to the target parameter setting strategy.
Specifically, after the target parameter setting strategy is determined, the memory parameter values stored in the system parameter structure are updated according to the target parameter setting strategy, and it can be understood that the updated memory parameter values in the system parameter structure can further ensure that the capacitance in the memory particles maintains the charge, so that the correctness of the memory storage data is ensured.
Step S4: and acquiring updated memory parameter values from the system parameter structure, and writing the updated memory parameter values into a register used for storing memory parameters in the system so as to enable the parameter setting of the memory to be effective.
Specifically, after the memory parameter value stored in the system parameter structure is updated, the updated memory parameter value is acquired from the system parameter structure, and then the updated memory parameter value is written into a register used for storing the memory parameter in the system, so that the parameter setting of the memory is enabled to be effective, and the occurrence of memory errors caused by insufficient charge of the internal capacitor of the memory is reduced.
The application provides a method for setting memory parameters, which comprises the steps of storing preset initialization parameter values of a memory into a system parameter structure in the starting stage of a system; determining a target parameter setting strategy which is matched with the total error times in the last operation process of the memory system according to a preset error times and parameter setting strategy matching relation; updating the memory parameter values stored in the system parameter structure according to the target parameter setting strategy; and acquiring updated memory parameter values from the system parameter structure, and writing the updated memory parameter values into a register used for storing memory parameters in the system so as to enable the parameter setting of the memory to be effective. Therefore, the application configures the respective adaptive parameter setting strategies for different error times so as to select the adaptive parameter setting strategies to set the memory parameters according to the total error times in the last operation process of the memory system when the system is started, thereby being beneficial to improving the error condition of the memory.
Based on the above embodiments:
as an optional embodiment, the preset process of the adapting relation between the error times and the parameter setting policy includes:
a first parameter setting strategy is configured for a preset first error frequency range; the first parameter setting strategy is used for setting the parameters of the memory according to the user-defined memory parameter values.
Specifically, the first adaptation condition of the adaptation relationship between the error times and the parameter setting policy of the present application is: presetting a first error frequency range, and configuring a first parameter setting strategy for the preset first error frequency range, wherein the parameter setting principle of the first parameter setting strategy is as follows: setting the parameters of the memory according to the user-defined memory parameter values, namely, the user can set the memory parameter values according to the actual application scene by himself, and taking the memory parameter values set by the user as the parameter values actually set by the memory.
As an optional embodiment, the preset process of the adapting relation between the error times and the parameter setting policy further includes:
configuring a second parameter setting strategy for a preset second error frequency range; the second parameter setting strategy is used for increasing the preset initialization parameter value of the memory and setting the parameters of the memory according to the increased memory parameter value; the first error count range is greater than the second error count range.
Further, the second adaptation condition of the adaptation relationship between the error times and the parameter setting policy of the present application is: presetting a second error frequency range, and configuring a second parameter setting strategy for the preset second error frequency range, wherein the parameter setting principle of the second parameter setting strategy is as follows: the preset initialization parameter value of the memory is increased, and the parameters of the memory are set according to the increased memory parameter value (because the increased memory parameter value can ensure that the capacitance in the memory particle maintains the charge more than the preset initialization parameter value of the memory).

a third parameter setting strategy is configured for a preset third error frequency range; the third parameter setting strategy is used for reserving preset initialization parameter values of the memory; the second error count range is greater than the third error count range.
Further, the third adaptation condition of the adaptation relationship between the error times and the parameter setting policy of the present application is: presetting a third error frequency range, and configuring a third parameter setting strategy for the preset third error frequency range, wherein the parameter setting principle of the third parameter setting strategy is as follows: the preset initialization parameter value of the memory is reserved, that is, the parameters of the memory are still set according to the preset initialization parameter value of the memory (which indicates that the memory error is not much, and the preset initialization parameter value of the memory still can meet the requirement).
It should be noted that, the first error frequency range > the second error frequency range > the third error frequency range, and the effectiveness of the parameter setting policy for improving the memory error condition is as follows: the first parameter setting policy > the second parameter setting policy > the third parameter setting policy. It can be appreciated that the more memory errors, the more efficient parameter setting strategy is needed to reduce the occurrence of memory errors due to insufficient charge of the internal capacitor.
As an optional embodiment, before determining the target parameter setting policy adapted to the total number of errors in the previous running process of the memory system according to the preset matching relationship between the number of errors and the parameter setting policy, the memory parameter setting method further includes:

Furthermore, the application also presets the adapting relation between the strategy options and the parameter setting strategies, namely, the parameter setting strategies which are respectively adapted are configured for different memory strategy options on the BIOS (Basic Input Output System ) interface of the system. The present application provides two ways of determining the target parameter setting policy: 1) Determining according to a preset strategy option and parameter setting strategy adaptation relation; 2) And determining according to the preset error times and parameter setting strategy adaptation relation. The application preferably selects a first mode for determining the target parameter setting strategy:
judging whether a memory strategy option on a BIOS interface of the system is selected; if the target parameter setting strategy is selected, the step of determining the target parameter setting strategy matched with the total error times in the last operation process of the internal memory system according to the preset error times and parameter setting strategy matching relation is not carried out, but the target parameter setting strategy matched with the currently selected target strategy option on the BIOS interface is determined according to the preset strategy option and parameter setting strategy matching relation, and then the internal memory parameter value stored in the system parameter structure is updated according to the target parameter setting strategy matched with the target strategy option. If not, entering a step of determining a target parameter setting strategy which is matched with the total error times in the last operation process of the system according to the preset error times and parameter setting strategy adaptation relation so as to update the memory parameter value stored in the system parameter structure according to the target parameter setting strategy which is matched with the total error times.
As an optional embodiment, the memory policy options include a custom option, an on option, and an off option;

Specifically, the memory policy options of the present application include a custom option, an open option, and a close option, and a user can select according to an application scenario. When the user selects the custom option, the memory parameter option is displayed on the BIOS interface of the system, the user can set the memory parameter value according to the application scene, and since the memory parameter value cannot greatly affect the performance, the maximum value and the minimum value of each memory parameter need to be limited, so that the user selects the parameter value from the maximum value and the minimum value of each memory parameter (the limited parameter adjustment range can be set based on the memory bank parameter percentage of the current server, and the width adjustment parameter proportion range is 100% -130%). Judging whether a memory strategy option on a BIOS interface of the system is selected or not in the system starting stage; if the custom option is selected, the memory parameter values stored in the system parameter structure are updated according to the memory parameter values custom by the user.
When the user selects the on option, the memory parameter options on the BIOS interface of the system are hidden. Judging whether a memory strategy option on a BIOS interface of the system is selected or not in the system starting stage; if the opening option is selected, the preset initialization parameter value of the memory is increased, and the memory parameter value stored in the system parameter structure is updated according to the increased memory parameter value.
When the user selects the shutdown option, the memory parameter options on the BIOS interface of the system are hidden. Judging whether a memory strategy option on a BIOS interface of the system is selected or not in the system starting stage; if the close option is selected, the memory parameter values stored in the system parameter structure are retained.
