Wanting to add new RAM with old ones

Hey guys,

I built a computer and salvaged 3 X 2GB 1333mhz DDR3 sticks from my previous HP desktop. This is the model type:

So I want to upgrade my RAM since 6gb is not enough and found a great deal from ripjaws 2 X 4GB 1600mhz DDR3:

I know that by mixing, all of them will run on 1333mhz but I want to know if they are compatible with each other. I also know that both have CAS of 9. With 2 x 2gb and 2 x 4gbs, I can get 12gb of ram

Also its totally fine if I have to end up running the two ripjaws by themselves. I'll just be a little sad.

Thanks.

Mixing and matchig ram can be preatty fickle, you cant really know if it will work unless someone with your specs already tried the same conbination

I guess I should just check through trial and error then? I'm going for the 8gb ram anyways.

Yeah, and even if it dosent work 8gb still a nice amount of ram

Depending on your workload a 1600MHz 8 GB might give you more performance that a 12GB 1333MHz 12GB RAM. cause going from 1333 to 1600 has a noticeable difference. So go for that 8GB if it works, try it for yourself about the 1333 and 1600.

And even if someone with the same specs tried it, it would have different results on your PC.
