query on dell laptop RAM make

[iinfi]

my roommate has a dell inspiron 1525.
it came with 3gb RAM. now he has some issues with the laptop (display gone) and a local laptop repair fellow opened it and found 2gb RAM from samsung and 1 gb ram from hynix.
i m gobsmacked. i have never seen dell giving RAM from two diff manufacturers.

jus wondering whether you guys can throw more light on this.!

if dell's doing this it should work. You shouldn't have taken it to your local hardware guy as your warranty becomes void. Contact dell for any problems with your laptop.

its a 4 year old laptop ...its not in warranty..
i dont know whether dell has given it this way or whether some other local laptop repair fellow to whom my room-mate mite v given has replaced the original ones with these ones... my room mate has no clue
