Where is my PC Bottleneck?

Well first of all thank you for comming here to help me.

I recently got a 1080Ti (my old GPU was a GTX 970) and I realized that my FPS results are different from the Benchmarks or videos, even if they had quite similar specs to mine.

my specs are

CPU: I7 4790K
RAM: 16GB DDR 3 1332MHz (Single Channel) (8GB x 2)
Mobo: Asus H97M-E
GPU: 1080 Ti Asus Strix
HDD: 1TB WD Caviar Blue
SSD: Kingston A400 480GB

I personally think that is the RAM in single channel that is pushing the Pc back, I read some posts that said that when they have RAM in Single channel the GPU doesn't reach the limit of usage and mine is kind of similar because most of the time stays at 60-70% and the fps drop over 60 and that's kind of annoying

That's certainly doesn't sound normal; sounds more like a malfunction.

Make sure your RAM modules run on 1.5 V or less. While ASUS's manual seems to specify 1.65 V or less is okay, Intel has never actually stated, and probably never will, that 1.65 V will not degrade the integrated memory controller.

How are the modules configured in BIOS / UEFI? Have you made sure the board is set to auto detect the timings, or have you picked a memory profile, if one exists? Some system configurations can be picky about the RAM modules used, and will only operate them at their rated speed when painstakingly configured. Thankfully this is the exception, not the rule.

Have you ever run RAM diagnostic tests to determine if one or both module is...

The only reasons that come to mind for not running two RAM modules in dual-channel would be mismatched modules or malfunction.

To 2nd what SR-71 said, your system looks fine, except for the nagging question of why would you run that kind of equipment in single-channel mode. Any software that is sensitive to memory bandwidth is going to suffer a noticeable lack of performance.

The reason why I run it in single Channel is that I can't figure out how to make the RAM work in dual channel, i really think that is a malfunction on my Motherboard or something because make the mobo recongnize the 16 GB of Ram was and odyssey, one friend told me that I could put the battery of the Mother away, wait 10 minutes, and then put it back with the RAM in Dual Channel and it would recognize it.
Anyway I'm planning to change de Mother for another one compatible with DDR4 and also change de DDR3 Ram for other new ones running at 2000MHz, do you think that improve would "solve" the "bottleneck"

Change the slots the RAM modules are installed into.

Usually, you install the modules into like-colored slots. The like-colored slots usually alternate, because you want one of each color on each of the CPU's memory channels.

Provided your board matches the pictures and manual at ASUS's website, you want your modules installed in either the two black slots or two gray slots.

Have the two modules right next to each other is not the correct configuration for dual-channel.

No removal of the BIOS battery or any other change is necessary for the system to recognize and boot in dual-channel mode. If the CPU sees matching memory on both channels during the POST, it runs in dual-channel mode. Simple as that. The change is transparent to the operating system as well, although you can see if it's in dual-channel mode through software.

Yesterday I tried to do that, but no matter if I put both in gray or both in black, or i I switch them after that, the system doesn't boot, the first time the mother didn't recognize one stick of 8, after when i Switched to the Gray and boot the monitor just don't display Signal, And when I changed back to the start (A1 and B1) the Pc just went crazy and started to restart and shut down after 4 secs.
It seems that the Ram only work on particular Spots because If i Switch the position of them even if they stay in A1 B1 the computer goes crazy and start doing that, is it a malfunction on the Mother or is it normal?

Have you ever run RAM diagnostic tests to determine if one or both module is defective? Run multiple passes, and run the thorough tests if you use WMD, unless errors are found right away. It's best to let the memory tests run overnight.
