Thread Starter 
Brain lapse here.
So i need to upgrade some ram in my I7, It has six slots i already have 3x2GB i want to add a 3x4GB and have 18GB total with no issues right? Basically different size chips in the other triple channel slots, with no adverse effects.

Just make sure matched slots all have the same amount in them, but if there's different size sticks between the 2 sets of 3 slots it doesn't matter.

You'll need to increase your voltage on your memory controller. Especially for 6 DIMMs of 2000mHz RAM, with one set being 3x4.

Not sure how cool your cpu is running? But with added QPI voltage will cause a bit of extra heat. Probably not to much, but you might notice your cpu running a bit warmer.
