Can't unlock memory limit RAM

Now, I've changed the msconfig to boot with the maximum memory output and also ticked 2 cores, yet it still shows that I have only 3.45 GB usable. How can I unlock my whole RAM?

Have you tried clearing the CMOS? Tried the other 2 memory slots (if using 2x4 GB)?

Did you try GPU settings in the BIOS ?
Se how many RAM you`v have set to the GPU
And also you must have 4 cores and 4 threats ..... you have 2 that`s fishy here .......
Can you try testing install Win 7 ?

@dextermat

I do see the full 8GB besides the 3.45GB usable.

@alexoiu

How do I clear the CMOS?

@nikolai

I don't want to downgrade to Win7 since I just got this laptop yet.

I should tick the 4 cores? Nothing would happen?

 

[alexoiu]

Now I see it's a laptop.

I just optimized the BIOS and it got unlocked. Well that was easy.

F2 on boot and optimize boot.

Done.

Thank you all for your help.
