Abstract

Computer memory subsystems are increasing in density and speed while computer enclosure sizes keep getting smaller for the same number of components; everything contributing to an increasing thermal challenge. Previously, a system with multiple DIMMS hardly needed any direct cooling but, recently, designs have been challenged in the ability to sufficiently cool the memory subsystem. Current solutions to this problem include increasing the air flow with more fans or more expensive fans or limiting the number of DIMMS in the system. Modern chipsets help distribute this heat load among the populated DIMMS such that they all run cooler. However, a problem occurs when not all of the DIMMS are populated. In fact, the thermal problem at the memory level gets worse with fewer DIMMS, not better even though at the system level there is less total heat. Invention is the method to utilizes an empty memory socket and the volume above the empty memory socket for the addition of a cooling solution that is attached to a memory DIMM that occupies the memory socket directly adjacent the empty memory socket.

Method of Cooling Single Memory DiMM in 2 DiMM Per Channel Configuration When One DiMM Is Populated

    Figure 1 below is a scan that shows how the invention will work in a 2 channel, 2 DIMMs/channel configuration. The empty sockets are populated with a cooling solution that increases the efficiency of memory cooling, increasing the amount of allowed power dissipation per DIMM. The method of volume utilization can be done in many ways, with various heatsink designs (one heatsink design is seen in the disclosure entitled "Heatsink For Cooling Single Memory DiMM in 2 DIMM/Channel Configuration When One DIMM Is Populated"). With this, an off-the-shelf cooling solution can be purchased to increase the bandwidth of memory in a given system.
