PCIe 3.0x16 @ x1 1.1

i have been having issues with my GPU since i bought it. HIS hd7970 ref. i have a couple screenshots and i was wondering if this was supposed to read like this or not.

i would assume it should be at least @ 2.0 x16.

am i right or am i just seeing things?

  1. click on the question mark by "PCIe 3.0x16 @ x1 1.1"
    then run the render test.
    watch the pcie 1.1 label.
    it will change to pcie 3.0.

    it changes it based on what your doing in order to save power,and task the power supply less.
  2. oh ok it went from x1 1.1 to x1 2.0
    but i thought it was supposed to run x16? my mobo supports 3.0 but using an i7 2600k i only get 2.0 should i try the GPU in a different pcie slot?
  3. your 2600k doesn't support pcie 3.0

    yeah try a new slot.
  4. well the pcie 2.0 is right since the "Intel Core i" 1st and 2nd generation only support pcie 2.0.
    but it should change to "@ x16 2.0" or "@ x16 2.1"
  5. it doesn't though. i goes to @x1 2.0
    i personally have had nothing but trouble with this pc since i built it.
    so should i try another pcie slot?
  6. theres hardly any difference between 2.0 and 2.1 so you should be fine with either. Whats worrying is that your getting x1 2.0 instead of x16 2.0. Maybe you should try a new slot.
  7. ok i will try a different slot. sometimes my pc is moody and doesnt recognize my card right away so it may take a bit for me to post back on this. will lets you know what i find

    did you even read what I said?
    "but it should change to "@ x16 2.0" or "@ x16 2.1"

    I said @x16 2.0 or @x16 2.1,as in depending on his motherboard.
    but the main point was x16 which he isn't getting.
  9. It may also just need to be cleaned with compressed air, or it may not be seating correctly. Poor contacts can cause that.
  10. are you sure it's in a pcie x16 slot?
    what motherboard do you have?do you know?
    and if you do know, what slot is the gpu in from the top.uppermost,2nd from the top,3rd from the top,etc.
    if you tell us we can check to see if it's in a x16 slot without having to remove that graphics card.

    I'm sure it's not a x1 slot. Those are short and a video card wouldn't fit in it.

    lol.
    I was referring more to something like a pcie x8 slot or something along those lines,where the lanes the slot can provide are limited by the motherboard.

    Ya, or even x4, but the problem is that it is showing x1, even after pushing the ? mark. That is what is concerning. It's most likely a seating issue.

    I think that your seating issue explanation is the best one.
    another theory is that the power supply is unable to power it so it's throttling the 7970.
    and the idea that I had was that the motherboard was limiting the lanes available to the graphics card.
  15. i tried reseating, no avail. i tried a different slot, the pcie 3 slot marked on the mother board and it still says x1.
    i do not know what is the deal.
  16. i have an asrock p67 extreme 4 gen 3. gpu was in the top slot next to the cpu. now its in the next slot under which is a x16 thats supposed to run at least x8
  17. Perhaps you should run 3dmark11 and see what the scores are. It could be a reporting error.
  18. downloading 3dmark11 as we speak
  19. Workload Single init returned error message: DXGI call IDXGISwapChain::SetFullscreenState failed:

    The requested functionality is not supported by the device or the driver.

    DXGI_ERROR_NOT_CURRENTLY_AVAILABLE

    thats what i got
  20. Now we are getting somewhere. Type that error into Google and see what you find.

    thats the scores on 3dmark11. i never got above 40 fps :(
    could this be a mobo BIOS issue?
  22. are your drivers the most recent from the AMD website?
  23. yeah using the 12.9 beta drivers since i am in the planetside 2 beta

    EDIT: probably going to get the 12.8 drivers and try those
  24. According to this, your graphics score is correct, assuming you have a reference clocked card. Look at the red bar on the reference 7970 score.

  25. I checked 3d mark too, turned out I was looking at the tahiti 2 gpu's which are clocked at 1ghz or higher.
    and yea his is stock reference tahiti 1 @925mhz and 5500mhz
  26. well i dont know. i am confused because i can not play League of legends without experiencing fps drops well into the 30's sometimes lower. thanks for all the help guys
  27. what's your full system?
  28. asrock extreme 4 gen 3 i7 2600k @ 4.2 ghz 8gb g.skill 1333 ram ddr3 his hd 7970 corsair gs600 600w psu

    what are the temps of the gpu and cpu while gaming?
  30. cpu 46c gpu 56
  31. I can't think of anything.
    you should be able to max that game out on a 6670,a 7970 should play it without breaking a sweat.
    aside from a defective component I'm out of ideas.
    the power supply is decent,not great but not bad.
    the cpu is great.
    the ram is good,1600mhz is ideal,but the change isn't that large.

    EDIT:try disabling hyperthreading in bios,it can lower your fps in some games.
  32. well after installing the 12.8 drivers and reinstalling my chipset drivers, i got it to say its @ x8 2.0 and i reran the benchmark and got these.

  33. Wow, bit improvement due to drivers.
  34. i had exactly the same problem and I fixed it by reseating the card on the slot and making sure it seats deep.
