When you purchase new RAM modules, installing them into your computer's motherboard is the first but not necessarily the last step. The addition of new memory components sometimes requires a little more involvement. Although most motherboards detect your memory timings automatically, tweaking the settings yourself will ensure that your system is taking full advantage of your modules.
Instructions
1. Access your computer's BIOS menu during the boot sequence when your computer powers on. The exact access key will vary with your motherboard, but some of the more common keys are DEL, F1 or F2. If none of those keys work, watch the boot-up screen for any information. Hitting "PAUSE" during the boot process will allow you to read any instructions about accessing the BIOS before the operating system begins to load. Consult your instruction manual if you have further difficulties.
2. Look for the DRAM configuration menu once you have accessed the BIOS. Again, the location of memory settings is highly dependent on your computer. Use the arrow keys to navigate the various menu items. Pressing "ESC" will return you to the main menu. Submenus you should check include "Advanced Chipset Features" or "MB Intelligent Tweaker" to name a few.
3. Switch the DRAM configuration option from "Auto" to "Manual." This option may be found under different names, such as "DRAM Timing Selectable." Toggling to "Manual" mode will allow you to access more in-depth options.
4. Update your memory settings. After the configuration mode is set to "Manual," you will be able to adjust a variety of latency and timing settings. If you are not sure of your settings, pressing ESC will return you to the main menu without saving any changes.
5. Press F10 to save and exit. Reboot your computer for the new memory timings to take effect.
