The time can be less than one hour, with low capacity and/or high speed, or can take an incredibly long time with high capacity and/or low speed (eg. 2 GB of SDRAM at 133 MHz can take nearly 24 hours).

RAM (Memory) Testing
SVANDUSEN 19:13, 26 May 2010 (UTC)
RAM is a deceptively simple device to test. It appears to be simply a matter of gathering, sorting,loading,removing, labeling, and storing; repeated over and over again. In actuality, there are a multitude of details and issues involved that would take far more space to cover than is alloted here. This is a very basic overview of the essentials that are necessary to get through the process. For more information please consult other experienced volunteers, instructors, or research such sources as Wikipedia or forums on Google.
