Hi I recently bought a ddr2 (4x2) two sticks of ram 400mhz I was wondering if I can add it up to 8gb because I bought it from amazon and I can’t cancel the shipping I was stupid enough to not check the specs and sorry I’m not that good in computer stuff I’m still trying to learn how will it break my motherboard if I just put it in? Also my desktop model is an Emachine ET1831 win 7 but upgraded to win 10
Originally had 3gb of ram

It doesn't have enough RAM slots for that and most it can use is 8GB in total. Only Xeons of that era could use more.
