Setting device program and method for setting a memory control

An apparatus, comprising:

• a memory that includes instructions for:
• acquiring first memory attribute information for a first memory module from an attribute memory in the first memory module;
• acquiring second memory attribute information for a second memory module from an attribute memory in the second memory module, wherein the acquired first memory attribute information and the acquired second memory attribute information include Serial Presence Detect information;
• accessing a setting value candidate database;
• determining a first data transfer rate setting value for the first memory module based at least in part upon the acquired first memory attribute information using at least a portion of the first memory attribute information as an index with respect to contents of the setting value candidate database to determine the first data transfer rate setting value;
• determining a second data transfer rate setting value for the second memory module based at least in part upon the acquired second memory attribute information using at least a portion of the second memory attribute information as an index with respect to contents of the setting value candidate database to determine the second data transfer rate setting value;
• analyzing the first data transfer rate setting value and the second data transfer rate setting value;
• determining a data transfer rate setting value that is to be applied to the first memory module and the second memory module based at least in part upon the analysis of the first data transfer setting value and the second data transfer rate setting value;
• and
• storing the data transfer rate setting value that is to be applied to the first memory module and the second memory module;
• and
• a processor that is configured to execute the instructions in memory.

A computer-readable medium comprising computer-executable instructions for:

• acquiring memory attribute information for each memory module in a plurality of memory modules, wherein each of the memory modules include an attribute memory that retains the memory attribute information;
• accessing a setting value candidate database;
• locating candidate data transfer rate setting values for each memory module in the plurality of memory modules in the setting value candidate database, wherein the candidate data transfer rate setting values correspond to the acquired memory attribute information in the setting value candidate database;
• obtaining current data transfer rates for the each of the memory modules in the plurality of memory modules, wherein the current data transfer rate is the data transfer rate currently being used to transfer data;
• comparing the current and the candidate data transfer rates;
• and
• determining a data transfer rate setting value that is to be applied with respect to each memory module in the plurality of memory modules based at least in part upon the comparison;
• and
• outputting the selected data transfer rate setting value to a host controller that controls data transfer with respect to the plurality of memory modules.
