I have a problem in overclocking a QDI BrillianX V (440BX) motherboard from 100MHz to 133MHz FSB using SoftFSB. The system seems to work stable if I turn off the DMA feature under the Device Manager. When this feature is turned on, the system runs very slow when performing a disk access, even though the PCI bus is running at 33MHz due to the 1/4 devider.
Does anyone has experience in overclocking this motherboard ? Is this motherboard stable at 133MHz for long periods of time?
I'll apreciate any help because those guys at QDI support won't answer my questions.
