RAM showing 2.57 GB instead of 4 GB

[sahil1033]

I own Lenovo E49 with Windows 8.1 and 4 GB RAM but in My Computer it shows only 2.57 GB and even my system is running slow. Opening more than 5 tabs in Google Chrome even slows down the system. Help.

Do you have a 32 bit OS or a 64 bit OS?

 

[sahil1033]

64-bit

Make this clear" does it say "4 GB (2.57 GB usable)" or something else?

 

[sahil1033]

Earlier (a month back) it used to show "Installed memory: 4 GB (2.57 GB usable)" but when i checked it yesterday, it said "Installed memory: 2.57 GB"

Run MemText64+ to confirm whether it's a faulty RAM. Also, do you have 2 GB x2 or a single 4 GB stick?

Try a system restore or a system repair using the installation disk.
