1. A method of selectively enabling error checking in an information handling system (IHS) that includes a memory controller and a system memory, comprising: receiving, at the memory controller, information indicating that data associated with a first memory portion in the system memory should be subject to error checking during transmission between the memory controller and the system memory and indicating that data associated with a second memory portion in the system memory should be free of error checking during transmission between the memory controller and the system memory; receiving, at the memory controller, a memory access request directed to one of the first and second memory portions; transmitting data between the memory controller and the system memory in response to the memory access request; and selectively performing an error checking technique on the transmitted data based on the information, the selectively performing including performing the error checking technique if the memory access request is directed to the first memory portion and including transmitting the data without performing the error checking technique if the memory access request is directed to the second memory portion.
