Having a Lenovo N200 notebook I decided to upgrade my memory from 2×1 Gb to at least 4 gigs.
Due to an advice from a friend of mine I almost picked up 2×2 Gb memory for like a hundred bucks, and I'd be good to go.
But, after visiting some webshops I came to the conclusion it'd be a better idea to purchase one 4 Gb memory and replace only one of the old ones.
So I'd end up with 25% more memory for a little less money.
Is this combination safe? Is there anything I should consider? (Already running x64, no need to remind me about that.)
