I have a dell XPS720 originally it had 2 GB of DDR2 1066 PC2-8500 RAM that ran at 1066MHZ and than I bought 2 more gigs and installed them, and I have to use third party programs like Rivatuner to tweak my system becuase I have no bios support, and I noticed my 4 GB's of Corsair Dominator PC2-8500 C5 10066 MHZ are running at 800 MHZ. So I know my computers only recognizing them as DDR2 800. Is there any kind of program that would let me change the timings and mess around with its voltages?
