Question PC Drastically Underperforming

(PC Specs Below)

A couple days ago I purchased a Asus ROG Strix RTX 2080 Ti 11GB in order to have better game performance. I upgraded from an EVGA GTX 1060 3GB. However, after I installed the new GPU, I found my games to be running at speeds that were slower than I expected. There was a small improvement compared to when the 1060 was installed, but it was not nearly what a Ryzen 7 + 2080 Ti combo should run at. I tried overclocking both my CPU and GPU, only to receive a boost of only about 5 FPS max in multiple games. I have tried running a few games set at the highest settings, then comparing performance to the same game run on lowest settings, and there was again only about a 5-7 FPS difference (Avg. frames in GTA V - 70FPS on lowest settings, 60 on maxed settings; Escape From Tarkov - 75 fps on lowest, 65 on maxed. Frames often drop below 60 in both games). I'm not 100% sure what's wrong or what would be causing this to happen. The only hint I have is that when I purchased my RAM, it came preset at a clock speed of 2133 MHz. When I tried to overclock/change the frequency to the advertised speed of the RAM, my PC would not boot, and I could only get into the BIOS.
I am only able to get my PC to boot when overclocking my RAM to 2400 MHz or under. I'm pretty new to overclocking, I've only watched a video or two on CPU overclocking. The video I watched also briefly described how to overclock RAM along with CPU, so I'm not sure if I'm just doing something wrong. I might not be giving my RAM enough power when clocking it to 3000 MHz, I'm not sure. I need to do more research on that.
However, I'm not even sure if the RAM is the reason my PC is underperforming. My friend with an i9 9900k and a GTX 1070 was able to get better performance in Escape From Tarkov (a difficult-to-run game) than me, despite having a CPU with pretty similar specs and a worse GPU. So I don't really understand what's happening. Anyone have any ideas what could be wrong? Any suggestions are welcome.

TL;DR: Bought a 2080 Ti, have a very decent CPU, 32GB of RAM, yet games are not performing as well as they should. :/

Specs:
CPU - AMD Ryzen 7 2700x overclocked to 4.1 MHz (cooled with Noctua NH-D15 Single Fan)
GPU - Asus ROG Strix Nvidia RTX 2080 Ti 11GB Vram (overclocked +191 MHz)
RAM - TridentZ DDR4 3000MHz 32GB (4 x 8GB) (each pair of 8GB sticks purchased at different times)
Motherboard - Asus ROG Strix B350-F GAMING
PSU - Corsair RMx Series RM750X 750W

1)Bad move mixing memory. That only serves to increase the odds of instability.

2)Ryzen 2700X will not run 3200mhz on 4 dimms. 2, but not four. You are limited to 2400mhz with 4 dimms.

3)Besides the memory mistake, the combination of 2080Ti + 1920x1080 monitor is a poor one. That's hardly an upgrade over a 2070 Super at that resolution.
Once you've reinstalled the driver, go into Nvidia Control Panel > Manage 3D Settings, and turn DSR to x2.

reading this i will tell you to just use 2 stick of ram and do a clean install of the drivers using DDU

Might be worthwhile running some 2D benchmarks and comparing the results of those to similar systems. If the problem is memory, it would also show in office-type workload benchmarks.

EDIT: and I would go with default clocks for everything until you have the speed issue identified and sorted. Overclock afterwards if you like, but figure out the root cause first.

Removing 2 of the ram sticks worked, my ram can overclock to 3000mhz now. But I'm still getting poor benchmarking scores and low framerates in games. I'm suspecting it might be my motherboard, I got it in 2017 and I'm not sure if it's handling such a powerful GPU very well. Not 100% sure though

What type of FPS are you getting? because as stated previously 2080 Ti on 1080P isn't gonna be super high framerates bc it isn't able to use what it's capable of.

In GTA Online on Ultra settings I get about 60-70 FPS average. I realize that the fact that i’m on 1080p is an issue and i’m hoping to upgrade to a 1440p monitor in the future but for now I’ve turned on DSR to x2 in the nvidia control panel, but it hasn’t made any obvious difference. Is this performance even with DSR on normal for 1080p?

It's not the motherboard:
2x 8 pin connections, 150w each, and only 75w through the motherboard's PCIE slot.
The Strix model has a max power limit of 280w, while the Strix OC model is 325w.

Is the gpu overheating in games/benchmarks - over 85C?

In GTA Online on Ultra settings I get about 60-70 FPS average.
Sounds about right. GTA V would've seen around 100fps avg at the same settings.

No, the GPU never goes above 75c or so in benchmarks or games. When I said " I'm not sure if it's handling such a powerful GPU very well" I meant in the aspect of data travel, not power. Sorry shoulda specified that

A friend of mine with pretty similar specs gets around 80-100 in Online. It just feels like I should be getting more out of a 2080 Ti? idk

A 2080Ti will fully saturate PCIE 3.0 in x8 mode. It's nowhere close to maxing the bandwidth on x16.

Similar is the key word. How similar?
Same cpu? Memory? Gpu? Monitor resolution? Game installed on the same type of storage drive? Internet plans are similar?
Seriously. All of those, and more will affect fps, from minor, to major. Both of you will literally need to have the exact same setups to make an informed comparison.

Same GPU and monitor resolution, installed on an SSD for both of us (not exactly sure which type of SSD), same amount of memory but his is overclocked to 3200mhz while mine is at 3000mhz, the main difference is that he has a 9900k and i have a 2700x. Originally I thought the performance gap between those two processors wasn't that substantial, but as I've been looking into the 3rd-gen Ryzens I'm thinking maybe my CPU just isn't as fast as I originally thought. Would there really be such a big difference in performance between my PC and his with a 2700x vs a 9900k?

At 1080p144Hz a 9900K is well faster than a 2700X.

I have the Strix OC 2080 Ti overclocked to 2085 Core 2000 mem and some GTAV missions lagg at 4K60Hz. Rockstar games are just optimized for consoles, very badely optimized for PC.

I would upgrade to 1440p144Hz as soon as possible to take more advantage of the GPU.

The performance difference between those 2 cpus is more substantial at 1080p, as opposed to 1440p or 4K, where the cpu matters very little.

Passmark Benchmark - 2700X VS 9900K VS 3600:
9900K = 32% faster single core, 19% faster multi core VS 2700X
3600 = 28% faster single core, 17% faster multi core VS 2700X

9900K = 3% faster single core, 2% faster multi core VS 3600... but a 3600 isn't going to cost you some 600USD for the cpu and cooler alone...

2080Ti: 9900K VS 2700X in game at ultra and low graphics settings
9(ultra) - 15%(low) faster on average at 1080p
8-15% at 1440p
7-15% at 4K


Summary: 9900K is faster, but for what it costs, it sure as hell isn't worth the gains.
