CMX4GX3M2A1600C9 : < 4GB Usable


Recommended Posts

Good Afternoon.


I slight dilema !! Hope you can help....


My System config is


O/S : Win 7 64 Bit

Memory : CMX4GX3M2A1600C9

MoBo : Gigabyte GA-H55M-UD2H

CPU : Intel Core i5 650


Having built and installed the operating system, when entering control panel and looking at the system it states that 4GB RAM installed but something like 3.74GB RAM usable. I was just wondering why there is some 0.26GB of RAM not available. I did not know if the additional RAM was dedicated to the On-Die GPU


Regards, Paul
