i have four ram slots

[kuyawis]

i have four slots of ram how would i know if it is all ddr2 or if its ddr2 and ddr3, it doesnt have any label and my pc is lg xpion

just google your motherboard name and number and see if it came with ddr2 or 3

if your system is more than 10years old it is likely to be dd2, if its more than 4-5years old is likely to be dd3, less than 4years it is likely to be ddr4

LG made/make several XPion models so you'll need to post the model number if you want help with RAM type.
