3090 Low performance, not sure why, need help

[BringBackGPUMascots]

Hey y'all, ever since I got a 3090 it's been underperforming compared to all the benchmarks, and I've tried many things to fix it but I'm still getting 15%+ performance loss compared to others.
For instance, Baldur's Gate 3 runs at under 120FPS on Ultra, when techpowerup's new bench states 175.
I don't have the best CPU (Ryzen 5700X) but compared to my friend that has a 6900XT and a 5700X, he still gets ~30FPS more than me in some games.
I've got no clue what to do anymore, what am I missing?

This is all on 1080p, so I understand the CPU matters, I don't expect MAX performance.

Things I've tried:
BIOS updates, different GPU drivers, chipset drivers, Windows is fully up to date(WIN 10)
Undervolting the GPU, and leaving it stock, same FPS.
Upgraded CPU from 3600X to 5700X, tried PBO2(works fine, i get 4.6GHz all-core)
My GPU temps are always around 65-70°C when gaming, memory temps are ~75°C
Removing all background programs(MSI AB gave me a few FPS extra after shutting it down)

PC Specs are:
Ryzen 7 5700X @ Stock with PBO2 on Auto
Gigabyte AB350M GAMING 3
MSI RTX 3090 GAMING X TRIO
32GB GSKILL/CORSAIR DDR4 3000MHz CL16
Windows 10 Pro 22H2 build 19045.3208
GPU Drivers: 536.99 Game-Ready


What else can I try? I could settle for 110FPS in all games, but this thing was a bit too expensive to "settle".

Thanks!

With X3D the ram doesn't matter as much.

I'll keep that in mind!

6000CL40 is pretty trash tier, but Europe might not have such good availability of low priced 6000/6200/6400 CL30/CL32/CL34 fare, so I dunno if that's all you can find over there.

It's an unenviable position be stuck in, I guess. Seems like a good idea to wait for new CPUs if you can't find a good deal on a 5800X3D.

Hmmm, I've found some 6400MT/s CL32 16x2 kits that are around 40$ more expensive, can't find any CL30 though. This is all important info cause it won't be long before I upgrade, a few months at max.
I think I should just deal with the performance I have and wait a bit.

In that freq range, the CL30/32 and some of the CL34 is Hynix, which is all that matters. Don't necessarily need CL30.

$40 for the difference between top tier on both AMD and Intel, versus absolute garbage, is undeniably worth it.

Here's a decent video to watch on ram scaling with Ryzen 7000/7000X3D

Yeah I'd definitely be down to avoid a situation like now by paying more upfront. Thanks for the info!

Thanks, 6000 CL32 would be moooore than fine then!
