I have a ram (Kingston KVR16N11S84 4GB 1600MHz DDR3 CL11) and i want to buy another stick. But i can't find the same model on Amazon. So my question is if i used different Rams(like only model change). So how much performance difference there will be if i used same frequency ram?
 
Don't buy another stick like that. Buy a 2x4GB 1600MHz RAM KIT and remove that 4GB you have right now. It's the only way to be 100% sure that both sticks will work fine together.

Even buying the same brand and model of RAM can give you issues when you buy both stick separately.

I don't have enough money to buy a kit. I have money to buy just a single stick so that's why I'm asking how much difference there will be in the performance between those two settings.

If you buy another 4GB stick of another brand and model or the same but 1600MHz here is what can happen.

  1. You put that stick in your system and everything goes fine. This rarely happen.
  2. You put that stick in your system and you have all sorts of issues. Mostly to happen.
  3. You put that stick in your system and it doesn't boot. Could happen.
So do you want to take the risk?

No the brand will be same and the timing will aslo be same. If 2 or 3 happens well i guess i have sell that stick then.
If i used same timing,brand and frequency module. Then is it possible those problems might occur?

Yes. You could buy same brand, same timing same everything and still have issues. The reason is that the RAM sticks were not produced in the same batch and not tested to work together. So the timing might be the same on the sticker but deep down it's not the same.

So yes. Problems could still occur. It's up to you :)

The point Nemesia was making is even mixing the exact same make and model RAM bought separately can have issues. RAM is sold in matched kits for a reason. I cannot say what that chances of issues are but it can happen, it’s happened to me once using 2 sets of the same model RAM.
