Build Advice Unknown problem is stopping my monster rig from delivering ?

[VeganBattleCat]

I bought a new gaming PC a couple of years ago:
CPU - i910900F
GPU - RTX 3080
RAM - 32GB RAM

And for all that time I have been underwhelmed by it's performance, specifically frame dips. In a bid to fix it I did an upgrade + a memory wipe. I upgraded the Mobo and added a 4090. Performance was undeniably better but I still get frame dips where neither CPU or GPU utilisation are anywhere near 100%.

I have just upgraded again having tried everything I could possibly think of from enabling Resizable BAR to updating the BIOS and so on.

So now I have a new CPU (i9 11900KF) and if anything the problem is slightly worse.

At this point my PC now looks like this:

Motherboard - ASUS ROG Maxiums XII Extreme LGA 1200 Extended ATX Intel Z490
CPU - i911900KF overclocked to 5GHz
GPU - RTX 4090
CPU Cooler - Not sure will check ASAP but it is liquid cooled
RAM - 32GB Corsair DDR4 Vengeance LPX 2666MHz
SSD/HDD - 2 x Samsung 970 Evo PLus 1TB
PSU - MSI MPG A850GF 850w
Chassis - ?
OS - Windows 11
Monitor - Sony BRAVIA OLED
BIOS version - will confirm but it's the very latest one (installed today)

I play on a 60hz TV and have zero interest in anything more than 60fps, I just want a completely locked 60 at max settings on 4K across everything and it seems utterly impossible at this point and I am beyond exasperated. Aside from the obvious expense of all these components it's absurd that I cannot get a consistent frame rate with the specs.

Interesting notes:

- Lowering resolution has little to no impact despite halving or even quartering the load
- DLSS or equivalent similarly seem to do nothing and if anything they add to the dips
- Most games have areas that are buttery smooth and one or two games (RDR2 springs to mind) are essentially immune to this issue but 95% of games I play are unable to hit 60fps at 4K with any consistency.
- I routinely check benchmarks for games to see what I should expect and I always fall short in practice
- The upgrades were all done by a friend who is a head of IT with 20 years of experience and he also cannot figure out why.

Can someone wave a magic wand or something cos I am so fed up with owning a near top of the line PC and having to judder through every game.

brand and model of the psu?
ssd?
cpu/gpu temp and usage during the game?
malware scan the system?
what os?

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Since you performed an upgrade, we'll be seeing a before and after of the build.

I upgraded the Mobo and added a 4090
Did you reinstall the OS in offline mode after the motherboard swap?

+ a memory wipe.
You mean to say you reinstalled the OS?

Sorry and thanks for replying.

Ok so:

PSU - MSI MPG A850GF 850w
SSD - 2 x Samsung 970 Evo PLus 1TB
CPU / GPU temps - never higher than 90 degrees and also the problem happens at any temp
System has been malware scanned several times and the new MOBO was added with a completely clean install of the Windows and formatting of the SSDs
OS - Windows 11
RAM - Corsair 32GB DDR4 Vengeance 2666MHz

Thanks! I will update the post

How big of a FPS drop are you talking about need munbers.
Some drops are normal and nothing you can do about them.

I'll need to speak to my friend who handled the upgrade re the stuff about offline mode but in answer to the second question yes I did a clean reinstall of the OS

I'm reasonable and I get that the odd frame hitch is just par for the course, I'm talking about dips into the low 50's even 40's and consistently in certain area, then in other areas smooth as silk regardless of the resolution regardless of DLSS being enabled just no sense to it

 

[Zerk2012]

I would call 50"s normal and if it's in just certain locations probably the high 40's also.

I disagree especially as it never comes with a maxed out CPU or GPU usage, is totally unaffected by resolution or most settings and hasn't changed one iota from i910900 + RTX 3080 to i911900KF + RTX 4090

Clearly that isn't normal right?

Why did you go with 2666 ram I would think 3200 would be a better fit.

Why would it max it out?
You might not understand how games and a. gaming PC works.

Came as a pre-made build, I doubt that is my issue though.

You don't seem to be responding in good faith so I'm just going to wait for others to respond. If I have that wrong then I apologise, I really do appreciate people taking the time to help me with my problem but this line of questioning / assumptions doesn't seem to be that.

If you run out of things to try you might want to keep the low speed ram in mind.

I am an old school gamer. I turned 60 this year. I have found in my experience with gaming systems that running the correct rated RAM recommended for the motherboard will improve responsiveness and increase the in game FPS and keep it consistent , of course your CPU and GPU and RAM will also auto overclock as needed to help keep the FPS within the game at a playable rate. I run the majority of games I play set at 60FPS with no issues and minimal bottlenecking between the CPU and GPU in my system with XMP turned on. You may want to consider the correct rated RAM speed for your motherboard. 2666 MHz seems a little slow for your rig. You may want to consider 1440p resolution for the TV. It may help keep the FPS consistent as well. Cheers.

Bob you might just have it. I noticed my RAM speed had been reset to some factory default (presumably when the BIOS was updated) so it was about 20% under what it should be - note this happened before and I thought it was going to solve everything but it didn’t. HOWEVER this time it does seem to have made a big difference so my working assumption is that my RAM speed is by and large the issue and I’m going to get something beefier.

Thanks

Thank you for replying, it looks like it is a RAM speed issue so I’m going to upgrade there and see what happens. But I fee confident based on a test I did last night.

@VeganBattleCat

Before upgrading, I suggest that you take a closer look at system performance via Task Manager, Reliability Monitor, and Process Explorer (Microsoft, free) to establish a working performance baseline.

Use all of the tools but only one tool at a time. Keep everything else constant as you check performance.

Key is to discover more about system performance and what all is consuming system resources and to what extent. RAM may or may not be the culprit. No harm in looking and verifying.

May take some trial and error experimenting to get a sense of it all.

Then do what you need to do to improve RAM speed and again observe system performance - hopefully performance will measurably improve.

You may discover other options and configuration settings that will help improve performance.

Some background app or utility running and grabbing system resources. Not needed and can be disabled or uninstalled even.

FYI:

https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer

Having some quantifiable measurements with respect to "before" and "after" will help determine if or if not any given "fix" makes a real difference.

Thank you Ralston18 for your advice. it is important to run some tests before upgrading hardware. I will consider this with my own system before hardware upgrades. Cheers.
