i just purchased a dell inspiron 3646 that has a pentium j2900 quad core and intel hd graphics. However it is only running 32mb of dedicated video ram! i need at least 64mb! first i checked dell's specification PDF and their claiming it comes with 64-256mb stock! then i checked my bios, (because dell's website was no help) and there is no option to set video ram. I am an experienced computer dude and have not ran into this issue before. Please help because this is my favorite pc.
