Intel HD i5 Problem

[K2 Khan]

Hi, i have an HP EliteBook 8440p
It Has Intel Core i5 M520 2.4GHz That Can Go Upto 2.93Ghz
Intel HD i5 520M That Has 756MB of Shared Memory.....
2GB of RAM, Will Upgrade It To 4GB......
Now The Problem is that according GPU-Z Shows That the core clock is 372MHz and default clock is 0Mhz + memory clock is 541MHZ while default clock 533Mhz.....

it Also show that it has 64bit bus width but gaame debate shows it has 128bit bus width.......

Game debate show that i can play batman arkham knights on Medium-High settings But I am Playing Crysis on Low-Medium settings.....
Whats The Problem????

Crysis is a much bigger game, which requires more ram to run! Thats all there is to it.. Once you upgrade your ram, you should be able to get atleast Medium settings

I Am Asking About The Core Clock i.e why it is 0Ghz while The Default Clock is 372Mhz?

Maybe because the GPU needs a little bit more ram to boost
