  1. I have decide to get a gtx 750ti lp for my pc which is a bit old, I used CPUZ to find the version of my pcie slot but there was no version stated there and I read somewhere that pcie without a version is usually 2.0, I dont want to use a powerful gpu on a v1 slot so please help me identify it.
    this is the report

    Please note all chipsets based on the P45 have PCIe 2.0. The P35 based boards are PCIe 1.1.

    Hello sorry for the late reply but I checked the wiki and my chipset is supposed to have pcie 2.0 but I checked using two different softwares (hwinfo, gpi-z) and it shows pcie 1.1.

    Thanks for the quick reply, but iam still a bit confused why is my card running at x4, my pcie x16 I know because x4 is alot smaller and x16 is longer like mine.

    A PCIe 16x slot can run at 1x, 4x, 8x, or 16x depending on hardware support and BIOS settings. Unfortunately, in your case, it seems to be a limitation of either the Intel chipset or how HP have configured the whole system - I think this is your system:

    If so, then page 75 seems to cover the issue:
    Edit: Just noticed another part of that document:
    Does your motherboard have two long PCI Express slots? If so, try putting the graphics card into the other slot.

    Edit 2: Here's another document (hopefully it's still the right one!)

    http://h10032.www1.hp.com/ctg/Manual/c01563108

    Here you can see the two PCI Express slots - the white one, although it is a full 16x slot only runs at 4x, whereas the black/brown one runs at full 16x rate.
