03-30-2017, 01:50 PM
Hi since I got this board iam trying to run my gpu on 16x pcie it wont it only run at 8x
done everything reseated the cpu cooler .... bios update ....cleared bios ... clean install .....tried different type of gpus .......
whatever I did it wont post 16x only 8x
mind u its all working good but the pain of seeing 8x instead of 16x when u have asus rog strix 1080 ti oc edition is too much to handle :)
plz advise

Click the ? to run a render test. See if the GPU clocks back up to x16.

And are you using any other pcie cards ? You could try reseating it if Chino's suggestion doesn't help.

My ROG Strix 1070 shows x16 1.1 at idle, under load it ramps to x16 3.0

Test your system outside the case. Use the motherboard cardboard box as a testbench and use the bare minimum. See if the problem persists.

I had something like that on my IX formula. I just returned it for another one

FWIW 8X is still more bandwidth than the card can use. This has been covered multiple times by multiple sources. The results on benchmarks were always well within the margin of error like 0.5FPS difference. When you add a second card its not going to matter anyhow as that slot is going to default to X8 and you will have two at X8 like I do.

Run a few benchmarks and compare them to others. My bet is you will be right there with others with similar hardware.

Try what Chino says, test out of case to verify if the case is not allowing for the card to seat fully into the socket, check the CPU socket for any damaged pins and heatsink mount for over tightening or uneven pressure

Hi -- what utility should I look at to see if My card is running at 16x? I have Maximus IX Hero and ASUS ROG strix GTX 1070. Thanks

I got SLi 970 GtX and i have the same stats with the box showing this outcome 16 x @ 8x like original poster..is this because i have SLI and they both run 8x and 2 x 8 is 16x ?

Hi Psycrow

That's correct, the i7-7700k has 16 pcie lanes and with two gpu's both will run at x8.

Problem solved by replacing the motherboard I returned it and got anew one ...., problem gone

Great to hear a new motherboard fixed you up and thank you for reporting back. :)
