Before we go ahead and see the way to check and change the memory timing we should understand what it is, because if we over clock the time or under clock the time it could result in non-functioning of the computer. We know that computer is a digital device and works on the presence and non-presence of the charge which is represented by 1 and 0 in binary language. All the processing power and speed of memory etc depends upon the number of times the chip can turn from 1 to 0 or 0 to 1. This change in the phase is called a one cycle and transfers and processing happens only during the rising of the cycle. The more cycles per second, more would be the speed of your computer. In this article we are discussing about the timing of the memory (RAM) so we will restrict our discussion only to it. The timing can be seen as the frequency of completing one cycle or completing some number of cycles in one second. The more the per second number the more would be the speed of your computers memory.

Every memory chip has its own defined speed limits and it works efficiently only if used within that range. You would have noticed that with advanced processors we need advances memory chips as well. People often over clock the speed of the memory and this results failure of the chip or crashes of the system. One should always be aware of the memory clock range before changing the same. Since all this is taken care by the BIOS of the computer so the settings related to the speed of the computer can only be viewed and changed from the BIOS. BIOS is the Basic Input/output System present on every mother-board of computer which manages and controls every hardware or chip connected to it. To enter the BIOS you need to start the computer and start tapping the key which is predefined by the manufacturer to enter the BIOS. Generally it is the Esc key or the F1, F2, F10 or Del key. Press the correct key and enter the BIOS. The interface of the BIOS would depend upon the make and version of the BIOS but generally you would find an option called “Advanced Chipset Options” in every BIOS on the very first screen.

Use the arrow keys to highlight the Advanced Chipset Options and press enter to see the further options. In the Advanced Chipset Options you would find DRAM Configuration option. Highlight this option using the memory keys and press enter. Now you will find the values like CAS Latency, RAS to CAS delay, Pre-charge, and Cycle time in the DRAM Configuration screen. The cycle time would be showing you the timing of your memory and if you wish you can change the same from here, but let me iterate that this should only be done if you know the correct configuration of the computer and cycle range of the memory.
