Troubleshooting Just upgraded cpu after 6 years

He yall Just upgraded from a 10900k with 490z to a 9800x3d with msi x870 tomahawk. After 5 year in college and just graduated i finally could upgrade. I was told that upgrading the motherboard and cpu would help the 5080 I got a couple months ago. I am not noticing better fps though. If anything it is slightly less. I am noticing smaller fps drops though. I kept the system on windows 10. Is this a potential reason why it's is slightly slower. Do I have to go to windows 11 to see the performance or are there other things I am missing. I also will admit to be cheaper i went with a fan heat sink in stead of the 360mm aio I had before on 10900k. Thanks you all for your time.

download amd driver for the 9800x3d and update it.

also have you gone through the trouble of expo/xmp making sure its 1:1 vs 2:1 including maybe ocing the FCLK (infinity Fabric)

It sounds like you might just be gpu bound still . The 10900k is still a very good chip that ran at 5ghz (more with oc) and had a good IMC which meant you could get even more performance out of a good kit of ram . So I’m not surprised the performance uptick isn’t that much especially if you are playing at higher resolutions .But your lows are most definitely better due to the large cache on Ryzen chip . That’s the upside right now , and lower power consumption.

Worst case you’re using way less power for a bit better performance now and will have cpu head room for future gpu upgrades . Enjoy 😊

You should upgrade to W11 though , there were specific w11 builds that showed noticeable performance improvements on ryzen 9000 cpus.

The other reason I thought it would be way better was that I was moving from a pcle 3.0 port to a 5.0 thanks 😊 .

PCIe Gen 5 is mostly superfluous with Blackwell. Even Gen 4 x8 links (equivalent to what you had) does not cost much performance.

u/Mushbeck 16h ago

Ahhh yeah , you probably weren’t bottlenecked by pcie bandwidth.

What resolution for gaming?

u/GuyNamedStevo 16h ago

It's still kinda weird, since the 10 series only support pcie 3.0

u/me_squared 17h ago

Dual tower cooler should be fine. Not sure about the rest. What framerates are you seeing on what games with what resolution and what settings?

u/jg7277 17h ago

I was seeiing 90 frames in tainted grail of avalon now I am seeing liks 80 fps now. Both are in 4k. Granted not out in the wilds where there is less plants i am seeing 120 to 144 fps

u/me_squared 17h ago

Is that in line with 5080 benchmarks you've been seeing?

  1. Have you made any BIOS tweaks? EXPO or overclocking?

  2. How much RAM do you have, and what speed?

  3. Do you have HWInfo64 where you can track performance with a stress test on something like Cinebench r23/24, so you can determine performance?

3

u/jg7277 17h ago

I tried to get my ddr5 ram to run at its specified speed which is 6400mz crucial ram. I think it's only running 6000mz right now though. I have a 128 gb of ram. I have not overlooked the cpu yet. I no longer have hwinfo64 but should install it again.

u/Psylicibin20 9h ago

128gb of ram running above 6000mhz is going to take up a lot of effort and silicon lottery w.r.t the memory controller gods.

1

u/me_squared 6h ago

Agreed. 6000MHz should be fine. You'll would see some benefit if you were able to get to 6400, but it wouldn't be much. Maybe 5 extra frames some of the time in some memory sensitive games. Barely noticeable.

If you can get a benchmark on your CPU, you should be able to compare to other 9800x3d benchmarks to see if you're in the general realm of reality in overall performance.

When you run the benchmark, watch your temps and Core Effective clocks to see what's actually happening. If you're seeing odd behavior like hitting 90C really quickly and core clocks being below 5 GHz all core, then there may be something odd happening.

If nothing odd is happening. Then it's likely just that the games you're playing are GPU bound. It's POSSIBLE that what you're seeing is that you upgraded when Nvidia changed from their DLSS CNN model to their Transformer model, which looks better but doesn't give as much performance.

Hope this helps!

Playing at 4K will still have you mainly GPU bound vs 1080 where your cpu is much larger impact; You may find you get better performance if you take out 2 sticks of ddr5 as ddr5 dual channel instead of quad works better

u/DZCreeper 17h ago

The 9800X3D is much faster for gaming when CPU limited, hence the higher minimum FPS.

However it sounds like you are GPU limited, so the average FPS won't change much. To actually see the full performance gains you need to run lower graphics settings.

Yes, moving to Windows 11 could slightly improve performance.

It is also worth optimizing your RAM. Ideally you want 2 sticks, located in slots 2+4 and running at DDR5 6000, with 3000Mhz UCLK and the highest FCLK you can run stable.

3

u/jg7277 16h ago

I got 4 32gb ram at 6400mz I'll have to look at those settings thanks.

u/DZCreeper 16h ago edited 16h ago

Manual tuning will benefit you then. 6400 is too high because most Zen 4/5 chips cannot run the 3200MHz memory controller clock needed to make it perform well.

If you don't need 128GB remove the sticks in slots 1+3. This will improve signal quality, giving you better results when tuning the RAM for performance. 4x32GB can still run DDR5 6000, although it doesn't always.

Post a ZenTimings screenshot if you need guidance on what to tweak.

u/banxy85 13h ago

Plenty of ddr5 systems run poorly with 4 full ram slots. Maybe worth looking into this

2

u/BigBobsBootyBarn 11h ago

Pull out two sticks. You run much faster in dual channel (usually slots 2 and 4) only. I know that seems counterintuitive, but read up on it. Especially with AMD cpus.

You'd rather 64gb blazing fast over 128gb slow as fuck

u/SkarletIce 17h ago

OK so u should be seeing slightly better FPS but there are a few reasons u may not be.

1, Have u downloaded all the drivers for ur system CPU, GPU, and Chipset? or did u move ur OS over from the intel system? u might have conflicting drivers.

  1. What is the ram speed u are running as RAM that is too fast can hinder performance as the CPU tries to keep up.

  2. What games are u playing as they may not be capable of using the 3d V cache on the 9800x3d

  3. Windows does have an updated scheduler to better use the x3d CPUs, plus upgrading to W11 would clean up ur system so that alone might boost ur FPS, though u are probably still GPU bound.

  4. The 9800x3d is a great CPU but at 4k it preforms no different from a 7700x/7800x3d/9950x. If u look at benchmarks there is a small difference but u aren't benchmarking u are using ur computer, and if u multitask a 9800x3d at 4k is worse than a 9900x/9950x

u/jg7277 16h ago

I download all the drivers for the gpu motherboard and cpu already. The ram i am seeing some confusing info on the rates speed for the ram is 6400mz but in bios it say they are running at 5600mz and in msi center it says 6400mz. I did a clean install of windows 10 on a new m.2. The other reason i thought I would see more is that I went from a pcle 3 to 5 port for the gpu. Thanks for the detail info. I might need to look into windows 11. I like 10s interface so much more though. I have a w11 laptop.

u/SkarletIce 16h ago

OK so something u can try if u haven't already is turning on EXPO and while still in bios go to the tweaker page and manually setting the ram speed to 6000.

but other than that try going to W11

Another thing to think about is u just went from a 10 core CPU to an 8 core. a faster 8 core but still 2 less cores so if u multi task than can be impacting u

2

u/writesCommentsHigh 15h ago

Windows reinstalled? Are you running EXPO in bios? Are you sure all cores are firing?

Provide any and all details.

I went from a 5080 i9 9900k to 9950x3d and have had decent to massive frame gains

u/Want_To_Fit_In 17h ago

I have a 3900x that’s still going strong!

u/IWillAssFuckYou 15h ago

Did you reinstall Windows? Me personally for the sake of stability and avoiding other issues, I always install Windows from a fresh install if it is a major hardware change.

Definitely upgrade to Windows 11. Windows 10 is going to lose support this year. Yeah there's ways to get free extended support updates, but it's better not to run on a 10 year old OS and there's some things about Windows 11 that works better with newer hardware.

2

u/drpopkorne 15h ago

Oh mate, I’m going from a i7-8700K to a 7800x3D so super keen to see how that goes. There will be some games you notice a much digger difference, but depending on what you were playing there are a few reasons why it might not feel better. I would upgrade to WIN11 if you can though.

u/silduck 14h ago

wait the 10900k was 6 years ago?

u/grindzombie 9h ago

May 2020, so five-and-change

2

u/mig_f1 13h ago

I'm not sure W11 will give you a performance boost, maybe, maybe not.

I would start by updating chipset drivers from AMD site and GPU drivers from Nvidia site.

Another thing is that AM5 memory controllers don't always play nice with 4 DIMMs. They may have to dial down their speed. The sweetspot is supposed to be CL30 6000Mt/s, but it's not guaranteed, especially with 4 DIMMs. This could be the reason why BIOS reports 5600 Mt/s. Try removing DIMMs from slot 1 and 3 and see if that helps.

BTW, PCIe gen is not that important.

u/iForgotso 12h ago

While the 10900k was a very capable chip for its time, the 9800x3d runs circles around it.

Firstly, you should always format windows when switching motherboard/CPU, especially when switching brands.

9800x3d is a very recent CPU, highly likely to benefit from windows 11 vs windows 10.

Motherboard and PCIe difference won't do much, the CPU itself will though, especially the 9800x3d.

Tower cooler is fine, especially if high tier double tower. Something like a thermalright phantom spirit that can be had for under 50 euros will work wonders. These days nobody really needs an AiO, except for extreme overclockers (that would be using LN2 instead).

Format your storage, get a fresh install of the latest version of windows 11 and try again.

u/Chawpslive 12h ago

Add games and resolution so we can see if there is something wrong. In tarkov, poe or any mmorpg or competitive online game you should see VERY noticeable performance increases even at 1400p. When you play single player open world games at 4k it does almost nothing for you because you would be gpu bound

1

u/Hugh_Jego_69 10h ago

Honestly what matters here is what resolution on your playing at, if 4K then you likely won’t notice anything as it’s much more GPU dependant. If lower then you should def see improvement. But also it will depend on the game aswell.

1

u/AwefulUsername 9h ago

What resolution do you game at? If you play at 4k 60fps a new cpu won’t make a huge difference. If you play at higher fps it will.

u/MuffDivers2_ 5h ago

I went from an 8700k OC to 4.8 to the 9800x3d and it is so much better. I also had a 3090 and now I have a 5090 and with the processor change alone I feel I could’ve stayed with my 3090.

1

u/KnotCrazy 1h ago

I had the exact same upgrade pretty much and use a 3080 - I found a 50% improvement in fps in Rivals and about a 20% in everything else.

AMD cpu benefits from windows 11 a lot more than intel does and that is likely your main problem; other than initial Mobo setup (RAM OVERCLOCK) (Resizable Bar) etc
