Step 1. DIMM modules have connections with different widths, preventing the module from being inserted backwards. Step 2. Verify that the locking tabs on the socket are swiveled to the outside open position. Some motherboards use a locking tab on only one side of the socket. Step 3. After verifying that the module is lined up correctly with the socket, push the module straight down into the socket until the swivel locks on each end of the socket snap into place at the top corners of the module see Figure A fair amount of force is required to engage the locks.

Do not touch the metal-plated connectors on the bottom of the module; this can cause corrosion or ESD. The memory module must be pressed firmly into place before the locking tab left will engage. For clarity, the memory module installation pictured in Figure was photographed with the motherboard out of the case.

However, the tangle of cables and components around and over the DIMM sockets in Figure provides a much more realistic view of the challenges you face when you install memory in a working system. Figure DIMM sockets in a typical system are often surrounded and covered up by power and data cables or aftermarket CPU fans and heat sinks, making it difficult to properly install additional memory.

When you install memory on a motherboard inside a working system, use the following tips to help your upgrade go smoothly and the module to work properly:. If the system is a tower system, consider placing the system on its side to make the upgrade easier. Doing this also helps to prevent tipping the system over by accident when you push on the memory to lock it into the socket. Move the locking tab on the DIMM sockets to the open position before you try to insert the module refer to Figure The sockets shown in Figure have closed tabs.

If an aftermarket heat sink blocks access to memory sockets, try to remove its fan by unscrewing it from the radiator fin assembly. This is normally easier to do than removing the heat sink from the CPU. Move power and drive cables away from the memory sockets so you can access the sockets. Disconnect cables if necessary. Use a flashlight to double-check your memory installation to make sure the module is completely inserted into the slot and locked into place.

Replace any cables you moved or disconnected during the process before you close the case and restart the system.

Note the positions of any cables before you remove them to perform an internal upgrade. I like to use self-stick colored dots on a drive and its matching data and power cables. You can purchase sheets of colored dots at most office-supply and discount stores.

Alan Sguigna. August 3, pm. And rightfully so. In general, most PC buyers are careful in selecting a processor, RAM, motherboard, storage and operating system. I feel that the main focus should be on selecting these hardware and that too which are compatible to each other.
