Laptop reserving 4.3gb/6gb of ram

[team flex]

Ok, so recently i decided to swap my ram because it seemed my laptop had a broken stick. However, now it seems system is reserving a lot. For some reason, it has reserved 4.3gb out of 6gb. No idea why. has never been like this. No option in the bios to change system reserved, bios is very limited.... need help asap, thanks a lot

Laptop is a sony vaio 2010

Sounds like your DRAM isn't compatible with each other or with the laptop, since you have a locked BIOS, not much you can do other than try different DRAM
