Hello!
I have problem with my PC.
GPU-Z shows PCI-E 1.1 when GPU loads:

With R7 260X shows correctly - PCI-E 2.0:


GTX1060 in other motherboard (Asus FM2+) shows correctly - PCI-E 2.0

My configuration:
Windows 10 x64 pro
Asrock 990fx extreme3 (bios 1.90)
AMD FX-6300 @4,4 Ghz (x22)
MSI GeForce GTX1060 Gaming X 6G
Ram 1600 MHz:
1) Goodram DDR3-1600 4096MB PC3-12800 Play Blue (GYB1600D364L9S/4G)
2) Kingston DDR3-1600 4096MB PC3-12800 HyperX Blu (KHX1600C9D3B1/4G)
3) Kingston DDR3-1600 4096MB PC3-12800 HyperX (KHX1600C9D3/4G) 
Sirtec High Power Element EP-600-BR 600W

So you have any idea what the problem could be?

" rel="nofollow - If you click the question mark next to "Bus interface" then run the test what does it say then?

Most systems will default to PCIe 1.1 when not under load to save power. If running the built in test does not change that then you have some kind of issue but I suspect it will.

" rel="nofollow - That isn't right at all. 

I assume you have the GPU installed in the PCIe 2 slot as per the manual's recommendation. Before we get into anything else: 

Have you cleared CMOS since installing the GPU?
Did you use DDU to uninstall previous drivers then install the latest for your system?

I did not clear CMOS, but I used DDU.
In other motherboard I did not clear cmos and didnt use DDU and Bus interface shows PCI-E 2.0 at once.

It's always a good idea to clear CMOS when installing new major hardware. It can be hit and miss otherwise. It basically just forces the system to reinitialize everything.

In BIOS Processor frequency stood 200 MHz, PCIE Frequency - 100 MHz.
I put these 2 parameters in auto and now PCIE shows 2.0.
But why so?

When you saved and exited it likely reinitialized the components and recognized things correctly. UEFI can be finicky at times but it's the same for all manufacturer's. This is why we always recommend clearing CMOS with new hardware additions. You don't strictly have to and most often things work fine but it does help rule out issues like they one you just experienced in one simple step while you have the PC open anyway. 

You should be good to go now Wink

If again Processor frequency to set 200 MHz and PCIE frequency to set 100 MHz,  then PCIE again shows 1.1...

" rel="nofollow - That should be the default frequencies anyway so why no just leave them at auto? It would appear that altering the PCIe frequency is causing it to default to v1.1. Most likely some kind of safety feature or bug. The stock value is 100mhz anyway so I would just leave that one set to auto. I am curious if setting the CPU frequency to 200 while leaving the PCIe set to auto causes the bug.

If you are not happy with leaving things set to auto you can contact tech support directly on the matter though I don't see the need to set the values manually when they are set to defaults anyway.

Thank you. It will work in auto mode.
I have already written in the technical support :)

Enjoy the GTX 1060, it packs one hell of a punch for it's price and now you are getting the full grunt of it with PCIe 2.0 Thumbs Up

Let us know if Tech Support are able to resolve the issue with manual settings.

Hmm. For a moment it seemed I had the same issue. I hadn't even noticed there might have been an issue before reading this thread. Motherboard 970M Pro3, GPU EVGA GTX 1060 SC 6GB. Newest BIOS for the motherboard, but I'm not sure if the firmware for the GPU is the newest version any longer, since my system doesn't recognize the subvendor of the card, which prevents me from using EVGA's software to update the firmware...

In any case, I'm not sure if running the render test would have helped with the previous version of GPU-Z I had, but with the newest version the PCI-E 1.1 seemed to just be caused by power saving features. Starting the render test switched the PCI-E version to 2.0. I also noticed that unlike my older version of GPU-Z, the newest version also recognized and displayed the technology, die size, release data and transistor count. It still doesn't recognize the subvendor, though...

Holy sheet Xaltar. Looky who's returned from being a Zombie for quite awhile now. Since Oct 15 huh?

It's strange GPU-Z does not recognize your GTX 1060 as being an EVGA card. That latest version of GPU-Z is dated 10/18/2016. Since techPowerUp is video card oriented, you'd think their fan base would be screaming for a fix for that, if it was a common problem. That implies that your problem may be unique to you? An old GTX 760 I have has the Subvendor field populated with EVGA.

That's quite a Catch 22, if you can't update the VBIOS/firmware without an update to the firmware to fix the Subvendor data? Are you sure that is the true issue?

The shift to PCIe 1.1 is caused by power saving features in the card, in your case, and in mine. At idle, my 760 shifts to 1.1 (2.5GT/s), and starting the render test caused it to immediately shift to 3.0 (8GT/s) which my board supports. That is not caused by Windows Power Plan option PCI Express Link State Power Management, since changing that in Win 10 to off does nothing to the PCIe link speed to my video card.

In the case of the OP of this thread, he wrote this:

Processor frequency to set 200 MHz and PCIE frequency to set 100 MHz,  then PCIE again shows 1.1

For AMD systems, I don't know what he means by Processor frequency to set 200 MHz, which I assume is really like the Intel BCLK (wardog, no comment on this??), which is multiplied by the core ratio/multiplier to produce the CPU/core speed/frequency.

On most Intel systems, the CPU's BCLK and PCIe clock are shared (not on Skylake and Kaby Lake), which can lead to failures of PCIe devices if it is changed. As Xaltar said, there might be some safety feature on AMD systems that prevents a bad PCIe clock rate from causing the PCIe devices to fail to operate.

Does the OP's statement make any sense to you?

Sort of. The processor frequency is indeed the base frequency that is multiplied to get the actual CPU frequency. When overclocking the CPU in auto mode (on my 970M Pro3), the CPU frequency is left alone and only the voltage and multiplier are changed. I believe the CPU frequency is also the base speed that is used for the CPU-NB and HT, since the allowed speeds for these start at 200 MHz.

As far as I know, the PCI-E frequency affects the PCI-E lanes directly. The default value is 100 MHz. Increasing it has sometimes been used to squeeze out more performance from the GPU, but from what I've heard, it's not worth the risk. PCI-E speed is not really a bottleneck worth mentioning these days, stable increases can be as low as a few MHz and if one goes overboard, the motheboard can fry. If the overclock is done sensibly (a couple of MHz at a time), the user should see stability issues well before any smoke, though. Since I'm not sure there are any safeguards in place to stop the user from destroying his motherboard with overclocking the PCI-E lanes, going straight from 100 MHz to 200 MHz sounds like a very bad idea.

I have exactly the same problem 970a-g/3.1 + gtx1070. I tried different cards and different processors, and as soon as I try to set the frequency manually get the 1.1 version of the PCIe! And I do not like it, because my motherboard is positioned as the overclocked!
In support of me did not answer, but to clear the CMOS and change cooler CPU :)
