Macbook 1.83ghz intel core duo ram limitations?

I have one of the first produced macbooks.

Total Number Of Cores: 2
L2 Cache: 2 MB

I installed new leopard and it runs super slow. I was wondering if it is harmful to install 2x2gb owc5300 sticks. I run Reason 3.0 and its a huge task for this computer. As well as running photoshop by itself, its just too slow! Please help and let me know if it's possible. My brother purchased me these ram sticks as a gift and I want to put them to use.

I was wondering about the same thing, for my MacBook CD 2.0: https://forums.macrumors.com/threads/442967/

Apparently 2GB is the limit, so you need to get 2 x 1GB (which I have).

The upside is that is will be cheaper than the 2 x 2GB.

I've read and it will only use 2gb. So could I use just one stick of 2gb? Leave the other slot empty? Or could I use both and It will only recognize 2gb? OR have it recognize 4 gb and only use 3.3 to 3.3 gb? Im so confused!

Also I dont want my system to crash and end up with a non working macbook C1D.

Core duo machines can only support up to 2GB,for optimum results it's recommended you install 2 x 1 modules ( matched pair ) if you tried installing 2 x 2 it wont boot

I have the same MB with 1GB then I upgraded to 2GB since that was the limit and the harddrive to 160 GB.
