In Registry editor navigate to following key:

HKEY_LOCAL_MACHINE > SOFTWARE > BlueStacks > Guests > Android

You will see a Memory DWORD on right side. Double-click on the Memory DWORD to see the details of Memory currently used by BlueStacks.

You will see the details of Memory. You will see Value data 300 (Hexadecimal) by default, which mean 768 MB in decimal. This means your BlueStacks is using 768 MB of RAM, it is dependent on your PC’s RAM. If you have enough RAM in your computer and want to increase the RAM for BlueStacks, you can change this value data.

Step 4

Change the Base to Decimal so that you can type size of RAM in normal mode. Now, fill the size of RAM in Value data field. You can assign as much RAM to BlueStacks as you wish. Here, I am giving 1GB RAM to BlueStacks, so, I have filled 1024 in Value data field.

Click OK to apply changes. You can now close the Registry Editor. 
Now, start BlueStacks and see, it’s running faster and better than before.

You are advised not to assign more than 50% of your Computer’s RAM if you have 4GB or less RAM as it will lead your System to unstable and hanging state.

For example, if you have 8GB RAM in your PC, you can easily assign 4GB RAM to BlueStacks and it is more than enough. Anyway, enjoy fast BlueStacks! Feel free to comment if you face any trouble.
