I have a DFI Lanparty NF4 Ultra board and a 8800GTS 512 graphics card. The Graphics card is PCI Express 2.0 but the motherboard isn't. The bios indicates clocks possible from 100 to 145 mhz. I have upped my setting there from 100 to 120. I know that overclocking the PCI-X becare standardized from the NForce 590 series and up, but what should I expect from my DFI board? At 120, I noticed the PWMIC and NF4 chipset is about 2 degrees hotter than before, standing at 56 and 54 respectively. Any ideas and comments welcome.
