Question about my set up... Involving Graphics Card, motherboard, i5-3570k, etc.

Okay. So basically the reason I'm here asking this is I want to know if my MSI 460 GTX is being bottlenecked by an 8 lane PCI 3.0 slot or not? Does it need to go up to 16 lanes PCI or is 8 lane fine? The card itself is rated for PCI E 2.0 x 16, but is running at 2.0 @ 8x according to GPU-Z

Here's my setup as verified by CPU-Z\GPU-Z

  1. Better performance in the 16.

    Good sir, replying so fast, are you stalking me? :P
  3. That's weird. Your mobo is 3.0x16 for a single card so why is your GPU reporting 2.0x8? Do you not have it in the "top" slot?
  4. The card down clocks the pcie to 8x it's running 16x
    try running a game and then check gpuz while the game is running.
  5. Wait, better yet...

    I have, it still clocks in at x8. Even while running a benchmark, like OCPT. (sp?)

    No, I don't have it in the top slot, it's in the middle at present. Do I need to disable some settings in the BIOS to get x16 out of my middle slot? :x


    Sorry for all the edits and deletes, being a moderator on other forums, double posting annoys the piss out of me, so I do my best to not double post for the convenience of moderators on other forums. :)

    Update: The main reason I'm asking is I'm wanting to figure out if my PCIe 2.0 card meant for 16 lanes of PCIE 2.0 is saturating my 8 lanes of PCI e 3.0 bandwidth, and as a result needs to be moved up, or is it running fine in PCI x8 in a 3.0 slot?
  6. You can look there but some force the number of lanes based on the slot with the top always being the 16 slot.

    you need to have a PCI-E 3.0 gfx card for it to register, a 460 always will register as a 2.0 card. Also make sure that PCI E Link State Power management is off

  9. I know that my card is a 2.0 card. What I'm wanting to know, is that as it is in a pci e 3.0 slot, are the 8 lanes of PCI 3 bandwidth it IS getting SATURATED from a by the card's 2.0 interface, and as such, should I move it up a slot, and get full pci e 3.0 x16
  10. Ah...

    I run my PC on High Performance power plan, where link state power management is off by default, and yes, I did check and it is off. :) Good suggestion though.
