Windows 7: I now have 6GB of RAM, but mathematically it should only be 5GB

I now have 6GB of RAM, but mathematically it should only be 5GB

So this might seem like a silly question, but this laptop came with 2GB of Ram (2x1GB sticks) I replaced one of them with a 4GB stick and then did the reinstall. Under the system information window it says that I now have 6GB of RAM, but mathematically it should only be 5GB.

Do I need to configure this at all?

Type resmon into the Start Search, open the Memory tab and post a snip of it.
Having such lopsided RAM sticks will likely cause some problems, they always should be a matched set.

I have a 4b Gskill and I am waiting for the other 2Gb Gskill to arrive in the mail so they will match. The 2GB and 4Gb shouldn't be a huge difference if they are the same company correct?

And the same capacity.

In theory any combination of compatible modules should work. But that isn't always the case in the real world. Any difference in size, specifications, or manufacturer can have unpredictable results. For best results it is always best to use matched modules.

Gotcha. I can swap the 2 for another 4 then and have a total of 8GB of Ram, which wouldn't bother me at all

Thanks for the information everyone

They will work but not at their best. Matched means same maker, model, size etc bought in a kit of 2 or more modules.
An 8 cylinder car will run on 7, but not at its best.
