Well then. That eliminates the use of that ram. If you really need the performance boost but not a new laptop then the only things you can do are
A: Upgrade ram to the max which is 8GB DDR3 1333 MHz
B: Upgrade to windows 10 for free
C: (To get rid of the heat.) Get compressed air/gas
And if you want to get a HIGH performance mid priced laptop than these are some decent choices for 600-800 Dollars. Tell me your budget and I can catter to your needs and I will look for some top notch high performance pc's within your budget but these are some decent choises if you have a medium sized budget.
