Summary:A method for increasing a capacity of a memory is provided in the illustrative embodiments. Using an application executing using a processor wherein the memory includes a set of ranks, the memory is configured to form a cold tier and a hot tier, the cold tier including a first subset of ranks from the set of ranks in the memory, and the hot tier including a second subset of ranks from the set of ranks in the memory. A determination is made whether a page to which a memory access request is directed is located in the cold tier in the memory. In response to the page being located in the cold tier of the memory, the processing of the memory access request is throttled by processing the memory access request with a delay.
