Based on experience, I think it will do one of the following two things: - Not boot up while the out of specification RAM was installed. - Boot up, but only recognize the maximum ram the mother board specifies
You cannot do so. The basic reason is Ram acts as a temporary storage device to store your operating system and other essentials. Where as hard disk is slower and cannot be used for same to process.
When you try to boot the system, you will get a POST error message and will not be able to boot.
Since the computer won't work without both of them installed it doesn't matter which is installed first.
The amount of RAM installed can affect boot time because during boot-up, the operating system and applications are loaded into RAM. If there is not enough RAM to accommodate all the necessary files, the system may need to rely on slower storage devices, such as a hard drive, which can increase boot time significantly. More RAM allows for faster loading of files during boot-up, reducing the overall time it takes for the system to become fully functional.
In RAM Slots.
there is not enough ram installed
first the booting files are loaded in the RAM and these files are in the boot sector where operating system is installed . after loading these file then these files load the operating system in the RAM , some portion of RAM is Allocated by the OS. after that window is ready to perform tasks.
if you have installed two 512 MB of ram, then it could be due to ram slot. may be your one ram slot is faulty.
The computer detects the amount of RAM accessible during boot. On some systems the amount of RAM is printed on the screen during boot.
A computer will not accept a new RAM that has a different voltage than the factory installed RAM cards.
