Hi HBilal , 

 

Welcome to the Community Forums.

 

With an updated BIOS , it is already preset by manufacturers as they predict that the machines other onboard devices may need for functional performance (no option to change on BIOS).

 

There are even cases that takes more of the RAM that cannot be changed (OEM presets) and even more with an onboard graphics chip as set by the BIOS. Try to check more on your other computers to compare. 

Related reference here that can further explain why exact 4 GB is not possible.

 

Hope this help answer your query.

 

Regards

yes , but how come there are solutions for the same cases with this , and it works for other computers !?

For example the configruation method works with many devices and it makes it exact with the installed RAM . I dont know , its been more than a week searching for solution and haven't found . Anyway, thanks for replying .

Hi HBilal , 

 

It would work for those machines that manufacturer's BIOS would allow.

Take time to review on highlighted links and consult your IT department if needed.
