Hi all experience master outside, just wanna ask, i had a 512MB Apacer PC3200 CL3 ram in my Abit nf7-sl board, can i upgrade it with another Kingston 512MB ram? cause some of my fren claimed that Apacer only compatible with Apacer, mean both slot of ram also need to be Apacher, cannot mix with Kingston or other brand. is it true?
