Hey everyone. Thanks for your support ahead of time.
To start with, my CPU reads around 52°C during the CPU-Z benchmark (up to 63°C during AIDA), whereas HWinfo says my motherboard and VRM are about 50°C.
The Windows power management is set to Ultimate Performance.
I’ve noticed a steady decline in FPS in UE5, initially thinking it was just the game, but last night it became bothersome. I attempted a single-core benchmark.
In CPU-Z, my score jumps to around 4.32GHz.
Six months ago, after purchase, I expected about 512; I think it reached 4.3 with that score too.
Yesterday I made some changes in the BIOS and reduced RAM latency slightly. Now I see ~434.
(No background processes interfering.)
LatencyMon is around 80µs when CPU-Z runs and browser is open.
System details:
CPU: Intel core i5-10500 base 3.1GHz - Turbo 4.5GHz
Motherboard: H410M S2H V2 Gigabyte
RAM: KLLISRE 2x16Gb @ 3200MHz (actually running at 2666MHz due to motherboard, thanks to AliExpress RAM, no BSOD since using it)
Storage: NVMe Kingston KC2500 1TB SSD (has DRAM)
GPU: Eagle RTX 3060ti
Power Supply: EVGA 750W GQ
Case condition: It’s really airflowed and I’m hoping temperatures aren’t the issue.
I’m a bit confused and open to learning something new. Hope we can solve this together. Thanks for reading! 😀

Hello and welcome to the forum. Would you kindly run userbenchmark (https://www.userbenchmark.com/) and share the link to your full results here? Make sure no other applications are running. PD: You didn't mention the type of CPU cooler you have, nor whether you attempted to play the UE5 game with the PC case side panel off?

I believe there might be a problem here.
Here, an I5-10500 should perform around 515 in the CPU-Z benchmark test.
This will differ slightly depending on other systems with better RAM, but not too much.
I can't give a clear reason except that you might have a fake I5-10500 or maybe an I5-10100.
I could also mention that many think UserBenchmark is not very useful.

Before all thanks for the replies now I don't feel like Im insane here
Sorry for further loss of brain cells, as Ive lost all of mine so im kindly asking for someone to spare me some
The cooler I didn't list because Im not sure exact model and its performing great, and I've mentioned that the temps are great. Its a cooler master with 4 pipes and mx-4 thermal paste. Yes I've tried with no glass panel and its 1 degree lower at best, as Ive said the case is really airflowed. Im pretty sure its a real i5 10500, cpu z detects it and I've said that I had score of 512 when I first got it. Here is the userbenchmark even though I don't know how is this info useful:

Hey there,
Start by downloading and launching Throttlestop. Once running, navigate to the 'Limits' section, then execute the built-in TSBench. The limits box will indicate why your CPU is throttling. Record any red flashes you see. TS Bench is helpful because it adds more stress to the CPU compared to CPU-z Bench, though it isn't as thorough. It serves well as a reference point.

H410M S2H V2 Gigabyte features extremely few VRMs and lacks cooling. If your board shows any heat, verify the readings. These models depend on downflow coolers for airflow; swapping to a tower cooler might not provide adequate cooling for the motherboard. A simple test could be directing a fan toward the CPU socket to assess improvement.

Ubm indicates you might be using up disk space quickly; consider freeing up an additional 50-75GB. If the gigabyte site can discuss this, review your system's current settings.

Maybe some things have shifted over the past six months.

Sorry in advance everyone, if this was just a simple mistake, please be patient with me. Thank you all for your time—I hope I don’t waste it.

Hey, here’s the TS Bench.
Yeah, I actually have a tower cooler, but it’s the same since I got the CPU.
I’ll take some time now to free up space and run the bench again. I’ll also try attaching some random heatsinks to the VRM.

Honestly, I’m not sure what might have changed. I haven’t downloaded any programs since then or replaced any parts. I’ll run a malwarebytes scan too?

The CPU can reach up to 4.5ghz with one or two cores. The maximum boost across all cores is 4.3ghz.
