GPU not detected in PCIEX16, but working fine in PCIEX4(new CPU)

[crepper4454]

I swapped my i3 6100 with a i7 7700k. Now I am experiencing a very weird issue. My GPU is 1050Ti 4GB.
PCIEX16+i3= GPU WORKING
PCIEX4+i3= NOT CHECKED(there was no need)
PCIEX16+i7= GPU NOT DETECTED AT ALL
PCIEX4+i7= GPU WORKING
As we know, GPU in a X4 slot can cause performance drop, which I do not want to deal with. I do not know why this happens and I can't find a fix. GTX drivers are up to date(reinstalled them a few times, most recent when I found out that it works in a PCIEX4 slot. Help please.
PS I am pretty sure this is a software issue.

What about CPU drivers? Did you install/update them when you swapped out the CPU? I would go to manufactures website and download CPU and Chipset drivers.

 

[androbourne]

If you are unsure just download the Intel auto detector tool and let it find them for you.

Normally CPU drivers are installed no problem from Windows Updates but they can be outdated or sometimes skipped. If you look in device manager and open CPU section you can see it has drivers for it.

 

[crepper4454]

Windows update is disabled because I do not have Windows 10 and I use a 7th gen CPU. I know there is a fix on that but I do not want to mess with updates before I get the PC up and running.

 

[androbourne]

Well that is most likely your issue then. New CPU but no drivers because Windows Updates is disable.

Try that auto detector tool and see if it can find the drivers for you. If not go to mobo manufacters page and try download chipset and cpu drivers from there. (normally they are included in chipset drivers).

Or just apply that patch fix and download from Windows Updates. I have used that patch before and never ran into any problems. I'm sure if you enable it now, it will be fine.

 

[crepper4454]

Intel tool have not found anything, but Windows Update detected 2 driver updates, one is called system. I'll download them and post the results here.

 

[androbourne]

Ok great.

 

[crepper4454]

- installed 2 driver updates
- pc shutdown (installation complete)
- port swap
- not working
- port swap
- install all remaining(not driver) updates
- reboot (to finish installation)
- shutdown
- port swap
- not working
ffs, what kind of sorcery is this s**t

Is there a way to uninstall chipset drivers? Maybe those from the i3 conflict with something. I would try with device manager uninstall, but idk is it a good idea, what do you think?

Not sure why your problem is manifesting in this fashion, but this right here is your problem. Kaby Lake does not support any Windows OS prior to Windows 10. Period.

If you want to use a Kaby Lake (7th-generation) CPU in your system, you're going to need to update to Windows 10...which you should do, anyway, because your system hasn't been getting any more updates anyway (& especially not any security updates).

 

[crepper4454]

You are wrong. Some people are running kabylake with windows 8.1/7 with no problems(only thing, without installing "wufuc" you wont get updates), "not supporting" is basically Microsoft's "* you" to everyone that did not update to Win10. "Yerr pricks do not want Windows 10? So you won't get any new processors!" I do not like Windows 10 and I won't install it, maybe a new Windows in emm 5-6 years? I think new Microsoft OS will be out then. Okay, end of OS arguing. And if you say "Install Win10 and it'll work" - of course it will. but I have to many files to do a system reinstall and lose them all. If a simple system refresh would be my solution, I would just reinstall it - not looking for overcomplicated solutions on this forum.

So, back to the problem, the problem is that my i3 drivers' (must be the CPU's because I did not change anything else) leftovers are conflicting with my new CPU and it somehow affect the PCIEX16 port. So, my idea is to delete any trace of i3's existence from my PC ESPECIALLY CHIPSET AND CPU DRIVERS, and I assume everything will work fine. Maybe I should just try placing the card in X4 slot and booting with the I3(so I hope it'll remember it and then X4 slot should be fu**** not X16. BTW How could this be an OS-based issue if the card is not detected even before the OS loads? I just tried disabling the IGFX in BIOS and then even the X4 slot was not working. That has to be a driver conflict.

 

[androbourne]

Crepper what he is getting at is that it's not officially supported. Meaning Windows Updates might not even provide drivers for it because it is not supported on that OS. It also means that results may vary depending on the system. You may have to force install drivers in order to get it to work and that's even if you can find drivers for it.

 

[crepper4454]

I've updated chipsed drivers manually(the * intel tool was wrong), and some new "devices" showed up in system section of device manager. I found something called "Intel(R) Xeon(R) E3 - 1200/1500 v5/6th Gen Intel(R) Core(TM) PCIe Controller (x16) - 1901"
Now I know what I need to do - I need this driver for 7th generation. Intel updater is going to install the 6th generation because it is "not supported", so my hope is in you guys. I need 7th gen Intel Chipset driver that can be installed on "unsupported configuration". Thanks to anyone who helps.

 

[crepper4454]

Nope, that is not it. I think I'll take this pc to a repair shop and mayble they'll make this gpu detected. Or maybe i'll just try a PCIe riser to connect it to the 4x slot and 16x slot at the same time

Language, please.
Thanks.

Your only hope is a) rely on the kindness of "hackers" that write the code themselves (with zero guarantee that it won't be chock-full of viruses, backdoors, bots, & other malware), b) write the entire code yourself (with the complete understanding that you will have zero assistance from the motherboard manufacturer, the BIOS provider,& especially Microsoft), or c) realize that it's time to drop an old (9 years old, at this point), past-its-prime (it's two generations behind the current version of Windows) OS that, as time goes on, will not only lose support from Microsoft, but will also continue to lose support from developers (& I mean all developers, not just game devs).

And it's not like this was news. Windows 10 has been out for 3 years now. Kaby Lake has been out for a year, & they announced two years ago that it wouldn't support Windows 7 or 8/8.1 (https://arstechnica.com/information-technology/2016/01/skylake-users-given-18-months-to-upgrade-to-windows-10/). And I sincerely hope that PC isn't the one you use to access the Internet, since you've turned off your access to even the critical security updates that Microsoft is making available through 2020 for Windows 7. That's just going to lead to the same kind of situation as users ran into back when they refused to upgrade from XP to 7...

 

[crepper4454]

Windows 8.1 was released on 18th of october 2013, so how is this 9yo?
The critical security updates are enabled by "wufuc" tool, and why should I buy a 7th gen CPU for a PC without internet access?
I am going to refresh my pc now with an USB with Win8.1 ISO file, maybe this will work.

@USAFRet Sorry, not happening again
