  1. Hello.

    This is my first post on TECHSPOT and it seems like there is a good community here.

    I have a P7P55D LE from Asus, with an Intel Core i3 530 @ 3.35 GHz or a Bclk of 152. The board has 2xPCI-E with one at 4x. My Graphics card (Nvidia) will only work on the 4x slot. Probably because the board is an ATI CrossFire not an NVIDIA SLI.

    I have decided from looking at task manager's graphs that my Nvidia N9600GT MD512 is slowing the system down because even at 60+ FPS no O.C my CPU uses no more than 50-60%. I have to make the computer use the CPU more.

    The conclusions that I have to make are either
    a) the graphic card is crap
    b) an overclock is crap
    c) or the PCI-E 4x that I am using is crap

    I myself prefer C. So I have to move the card. Why won't it work in the primary slot that is closer to the CPU? Is there a jumper or something? Is it something to do with the card being biased to ATI Crossfire?

    If anyone can solve this it will be a huge help.

    Thankyou.

    RMA the board.
    The Video card should be auto-detected once it's inserted in the PCIe x16 slot.
    Unfortunately for Asus this seems to be a significant cause of returns for their boards ( a quick example here -note the first two reviews)
    Sorry to be the bearer of bad news.
    I presume you have disabled (or the boards BIOS has disabled) the IGP for the CPU.
