How do I allow more RAM to BIOS?

Poke around in the BIOS and look for an option named “XMP”. This option may be right on the main settings screen, or it may be buried in an advanced screen about your RAM. It may be in an “overclocking” options section, although it isn’t technically overclocking. Activate the XMP option and select a profile.

Can your computer boot without BIOS Why?

EXPLANATION: Because, without the BIOS, the computer will not start. BIOS is like the ‘basic OS’ which interconnects the basic components of the computer and allows it to boot up. Even after the main OS is loaded, it may still use the BIOS to talk to the main components.

What does BIOS do in a computer?

BIOS, in fullBasic Input/Output System, Computer program that is typically stored in EPROM and used by the CPU to perform start-up procedures when the computer is turned on. Its two major procedures are determining what peripheral devices (keyboard, mouse, disk drives, printers, video cards, etc.)

Realistically there’s no reason not to turn on XMP. You paid extra for memory capable of running at a higher speed and/or tighter timings, and not using it just means you paid more for nothing. Leaving it off won’t have a meaningful impact on the stability of the system or the longevity.

Should you enable XMP?

All high-performance RAM uses XMP profiles, because they all run above standard DDR industry specifications. If you don’t enable XMP, they will run at your system’s standard specifications that are dependent on the CPU you have. That is to say, you won’t take advantage of the higher clock speeds that your RAM may have.
