Note that the Intel® graphics controllers uses shared memory that is taken from the RAM memory installed on your computer.
The feature that sets the amount of memory that is used for video is called Intel® Dynamic Video Memory Technology and this will make the graphics controller only to use the amount of RAM memory that it requires to run the different applications or software’s.
I am afraid to say that there is no way to preset this to a specific value; however, you can limit the maximum memory that it can take only. You will see this option usually in BIOS and you will have 3 options, 128MB, 256MB and maximum DVMT. Other values can be found as 512MB, etc but this depends on the motherboard manufacturer and the amount of RAM memory installed on your computer.
Hello Kevin M
i understand that my graphic card will use as much RAM as he need. but the
thing is that after changing my HDD games that worked before like Farming
simulator 2013 that required 512 MB now will not work because the game see
it like 128 MB and other games to.
sorry for my bad English
The Video memory is set on the BIOS as mentioned before but if you are experiencing issues after changing the HDD I would say the problem is not related to the dedicated memory but the new hardware on the system.
