Hello.

I have change my 1060 6go by 1080 G1 Gaming and now i have a big problem.

I play Fortnite with:

- Asus VX279 1080p 60hz (i use 2 monitors)
- Asus X99-A II
- GTX 1080 G1 Gaming
- i7 6800K
- 16 go RAM 3200mhz
- 750 Watts Cooler Master
- Windows 10 64bits

And i have buy that graphic card for stream at 1080p 60fps but ingame i have 40-50 FPS ! And not all to epic.

I have reinstall news drivers, reset Bios and more but nothing change...

Can you help me please ?
Thank you.

The ASUS easy tuner is just overclocking the CPU which wont have much of an impact on the CPU. Even with the overclocked CPU, the GPU is performing in the 7th percentile.

It could be your PSU, I am not ruling that out, but I just think it is more likely that your GPU arrived defective instead of the PSU failing at the exact time you installed the new GPU. Additionally, reinstalling the 1060 should really eliminate the PSU. 750 watts is more than enough...
Your RAM is running at 2133 because it is not overclocked to 3200mhz. Just because RAM says 3200mhz, does not mean it will run at that speed natively. It just means it has been tested to run at that speed. Go into your bios and look for the "XMP" option and it will overclock your RAM to 3200mhz.

With that being said, your RAM speed is not causing the issue. Your GPU is in the 5th percentile of benches. This is why you are getting poor performance. I would start with drivers. Use this DDU tool to remove the old drivers and reinstall the new Nvidia drivers.

Yeah, the GPU will need to be installed on a PCIe x16 slot. The CLim: 1999 and the MLim: 2502 are your clock speed and memory speed. Both of those numbers are where they should be for that bench.

Typically, when I have an issue with hardware, it is not the hardware at all, it is something that I did or overlooked. But in this case, I think it may be a hardware issue. It could be your PSU, I am not a fan of Cooler Master PSUs, but a 750 watt PSU should have no problems pushing a 6800k and a 1080. If you have another PSU, you may want to give it a try. I would tend to think something is wrong with the 1080 though since you just got it. And this is just because of probability. I think it is more probably that you got a defective 1080 than your PSU failing at the exact moment that you installed the 1080.

Do you still have the 1060? If so drop it in and see how it does. At least that will rule out an issue with the PCIe slot on the motherboard.
 


I think your 1080 is defective. Your PSU should not have an issue pushing your rig. It has 744 watts on the 12 volt rail.

As for the bios, those configurations deal with the CPU and the RAM. They do not have an impact on the GPU. Some motherboards will have settings for a iGPU when a CPU has integrated graphics. I would have said to look at that but you have a 6800k and the x99 mobo does not have an integrated graphics component. So there is nothing to check.

I wont guarantee you that there is not another issue somewhere causing the issue, but I don't know what it is. We have tried the drivers, the PSU works with the 1060, since the 1060 works we know that the PCIe slot on the motherboard is working. That kinda removes any possibility of a component hardware failure except for the 1080.

You could try to reset windows, but I don't think that will make a difference, because again, the 1060 was working fine. I am not a big fan of the Overclocking software, maybe you could try uninstalling Asus Easy Tune and any GPU overclocking software you have installed (MSI afterburner/EVGA Precision X). Maybe you changed a setting in one of those applications by accident which is causing the issue.

Other than that, all signs point to the GPU.
