    So I guess I'm safe with my 7600gt.?.

    I wonder if the problem would turn up if I got an 8800gt.:think:

    you can download & use CPU-Z (CPUID) or GPU-Z (GPU-Z Video card GPU Information Utility) to check,
    here are some sample screenshots from my original article:

    Hello everyone...first post :wave:

    Just want to let everyone know that the ASUS P5K-E WiFi series boards also suffer from this PCI-e 1x bug. How do I know...I have one and I have this problem.

    I just noticed the article discussing the problem so I thought I would check my system and sure enough I seen my 8800GT running @ 1x in CPU-Z. I rebooted, loaded the BIOS, set all overclocking options back to the AUTO, saved + exited. Now CPU-Z reports 16x.

    I have only had the P5K-E WiFi for 2 days so I have not tried to fix this yet. All I have done so far is try running @ stock and it of course fixes the problem.

    When I figure out a fix for the P5K-E WiFi I will post it in this thread.

    CFF.



    My complete system specs:

    MB - ASUS P5K-E WiFi (P35 chipset, BIOS 1004)
    CPU - Core2 Duo e6750 (overclocked to 4.0ghz, 2000mhz FSB)

    Wow. Kinda worried now that I read your article. Hehe. :oops:
    I'll check my settings later.

    Since you said in the article that the bug happens when you overclock the PCI-e, would it still happen if there is no overclock?

    I'm running an 8800GT now on stock clocks. But from my 3D Mark 06 score with it, it seems to be on par with other graphics card out there with similar rig specs as mine. Hopefully all is okay. :pray:
