Hello,

the machine im adding to says iut can max out at 8gb ram. it has 4 in it. i bought 4 more...but the new ram was pc3 10500....will these not work together?

its just an acer quad core desktop....can pc2 and pc3 work together or not cuz for some reason it wasnt booting correctly when i tried mixing the two

pc2 is ddr2
pc3 is ddr3
they are incompatible and I dont believe they will even fit in the same socket. whats the model number of your acer comp?
