Hi, i would need your help. I wanna upgrade my cpu from core 2 duo e7500 to any core 2 quad of Q9 series. However, my mobo has Q965 chipset, that officially doesn't support core 2 quad, but it shouldn't support 45nm cpu as well and i'm using E7500. I've downloaded SiSandra Lite and it tells me my mobo could support 333Mhz FSB. My mobo is HP 0A50h with the newest bios revision. So, could i upgrade my cpu to core 2 quad or couldn't I? Thanks for any answers.
