System and method for providing per channel frequency optimization in a double data rate memory system

1. An information handling system, comprising:

a first Dual In-Line Memory Module (DIMM) on a first memory channel of the information handling system;

a second DIMM on a second memory channel of the information handling system; and

a processor configured to:

train the first memory channel to a first speed based upon a first performance level of the first DIMM;

train the second memory channel to a second speed based upon a second performance level of the second DIMM, the first speed different from the second speed;

launch a first application;

allocate a first portion of the first DIMM to the first application based upon the first speed;

receive first speed information for the first memory channel;

receive second speed information for the second memory channel;

store the first and second speed information to an Advanced Configuration and Power Interface (ACPI) table; and

ascribe a first priority level to the first DIMM and a second priority level to the second DIMM based upon the first and second speed information in the ACPI table, wherein the first priority level is higher than the second priority level.

2. The information handling system of claim 1 , the processor further configured to:

receive a memory allocation request from the first application, the memory allocation request including a request to allocate memory that is ascribed the first priority level.

3. The information handling system of claim 2 , wherein the processor allocates the first portion of the first DIMM to the first application based upon the request.

4. The information handling system of claim 1 , the processor further configured to:

launch a second application; and

allocate a second portion of the second DIMM to the second application based upon second speed.

5. The information handling system of claim 1 , further comprising:

a memory controller including the first and second memory channels, wherein in training the first and second memory channels, the processor is configured to direct the memory controller to train the first and second memory channels.

6. The information handling system of claim 1 , wherein the first and second DIMMs are Double-Data Rate (DDR) DIMMs.

7. A method of allocating a first memory channel of an information handling system and a second memory channel of the information handling system, the method comprising:

training, by a processor of the information handling system, the first memory channel to a first speed based upon a first performance level of a first Dual In-Line Memory Module (DIMM) on the first memory channel;

training, by the processor, the second memory channel to a second speed based upon a second performance level of a second DIMM on the second memory channel, the first speed different from the second speed;

launching, by the processor, a first application;

allocating a first portion of the first DIMM to the first application based upon the first speed;

receiving, by the processor, first speed information for the first memory channel;

receiving, by the processor, second speed information for the second memory channel;

storing, by the processor, the first and second speed information to an Advanced Configuration and Power Interface (ACPI) table; and

ascribing, by the processor, a first priority level to the first DIMM and a second priority level to the second DIMM based upon the first and second speed information in the ACPI table, wherein the first priority level is higher than the second priority level.

8. The method of claim 7 , further comprising:

receiving, by the processor, a memory allocation request from the first application, the memory allocation request including a request to allocate memory that is ascribed the first priority level.

9. The method of claim 8 , wherein the processor allocates the first portion of the first DIMM to the first application based upon the request.

10. The method of claim 7 , further comprising:

launching, by the processor, a second application; and

allocating, by the processor, a second portion of the second DIMM to the second application based upon second speed.

11. An information handling system, comprising:

a first Dual In-Line Memory Module (DIMM) on a first memory channel of the information handling system;

a second DIMM on a second memory channel of the information handling system; and

a first processor configured to train the first memory channel to a first speed based upon a first performance level of the first DIMM; and

a second processor configured to:

train the second memory channel to a second speed based upon a second performance level of the second DIMM, the first speed different from the second speed;

launch a first application;

allocate a first portion of the first DIMM to the first application based upon the first speed;

receive first speed information for the first memory channel;

receive second speed information for the second memory channel;

store the first and second speed information to an Advanced Configuration and Power Interface (ACPI) table; and

ascribe a first priority level to the first DIMM and a second priority level to the second DIMM based upon the first and second speed information in the ACPI table, wherein the first priority level is higher than the second priority level.

12. The information handling system of claim 11 , the second processor further configured to:

receive a memory allocation request from the first application, the memory allocation request including a request to allocate memory that is ascribed the first priority level.

13. The information handling system of claim 12 , wherein the second processor allocates the first portion of the first DIMM to the first application based upon the request.

14. The information handling system of claim 11 , the second processor further configured to:

launch a second application; and

allocate a second portion of the second DIMM to the second application based upon second speed.
