Good findings!

I myself searched for PCI Device driver or something similar in device manager with the show hidden devices option selected but so far no luck.

I've tried this on another different PC with a x670e-a asus rog strix and a different GPU and different 7950X3D and it's the same problem.
Other similarities between both PCs are:
The Motherboards are from Asus
We're using Corsair RGB fans
We're using logitech peripherals
Bios is version 1004
RAM is GSkill 6400 MHz Intel (XMP not EXPO)

Don't know what could it be, have you tried enabling Precision boost overdrive with a 200 MHz OC to see if you hit at least 37000 in cinebench? My primary problems are in gaming at 1080p, the CPU is not as fast as what reviewers report.

I didn't touch the boost frequency, I heard it doesn't actually do anything on these chips anyways as it's disabled for some reason, I just followed the skatterbencher guide for now and was going to check out what's up with the boost stuff later. I have an Asus X670E-E so I'm just doing a bclk overclock instead for now, I'm still tweaking and playing around.

I'm on a 7800x3d, my CPU bone stock on fresh install of windows gets 17,200 with a Arctic Freezer II 360mm AIO. Nearly all reviewers including those with worse cooling all get over 18,000, and AMD even told one of the reviewers to expect a score of 18,200. Even with a bclk overclock I still only get about 18,100. My single core scores are on par with reviewers though.

I managed to make it appear!

Go into BIOS, Boot, Boot/Secure Boot and in OS Type change it to Windows UEFI mode.

That finally made it appear in device manager, will reinstall chipset drivers to see if it makes a difference.

All credit is to some guy in reddit from 2 years ago lmao.

VBS should on or not? Cuz I'm still missing that PCI after change to UEFI mode.

Restore bios default settings, change nothing and try again.

This was why I suggested default BIOS settings, however I'm surprised that for @dexterhines UEFI mode is not enabled by default.

 

[yzonker]

Nice. Not sure what difference it would make but you are not using FSR Auto like Nizzen and I.

Apparently none. Slightly better. Min isn't quite as good, but I do have HT off.

I have 3x 7800X3D chips coming this week (don't ask) and I suppose I should bin them to figure out which one to keep. Could anyone tell me the best way to do this? just SP?

No...s

No sp means little.

F clock/imc sustainable clock speed under load and how much voltage you can pull away with CO. That's about it.

 

[zayd]

Folks, i dont know if this may help with some if your issues, but my BIOS kept freezing everytime i tried to adjust a setting on my X670E Carbon. In case this happens to anyone else, I actually found the fix on MSI's support page for BIOS updates and it must've been added recently. For some stupid reason, you have to download the BIOS using Microsoft Edge browser. I had this exact issue with my BIOS constantly freezing and only a hard shutdown was the option to move on and this was with the latest BIOS for my X670E Carbon. I downloaded BIOS again using Edge browser and not Firefox this time and all is fixed.

Oh I thought sp was pretty good indicator from some random comments I've seen. Isn't CO offset not a good indicator? As in, couldn't you get a CPU that only goes to -10 but regardless boosts to higher sustained effective clocks over one that goes to -35? In that case I'm picturing one has a much better VF curve and it just happens that the stock offset is close to the max VF whereas the worse CPU has a bad curve and the stock offset from that bad curve is also large. SP is a proxy for the vf curve so I thought better sp was better curve even when comparing different cpus (presumably the work Asus put into sp was making the number comparable).

So end the end I guess max stable fclk/imc/effective core clocks are the the only real way to know CPU quality right?

 

[chewonthis]

Sp used to mean something to extreme ocing. Seeing as I'm retired from extreme scene can't comment on it's usefulness. What I can tell you is that typically speaking lower leakage chips tend to work better for avg users. Higher leakage chips tend to be beneficial to extreme crowd.

Hello everyone, can anyone confirm what options appear when installing AMD's chipset drivers?

According to techpowerup (AMD Ryzen 9 7950X3D Review - Best of Both Worlds)
there should be 8 items that appear when installing but I'm only getting 7.

Techpowerup:

Could this be a reason as to why some people are seeing less performance in the X3D chips than other reviewers?
I don't know why AMD PCI Device Driver is not showing up on my end.

Things I have tried:

reinstalling windows
uninstalling and installing chipset drivers
reinstall gamebar

My specs:

CPU: 7950X3D
GPU:4090
MB: Asus X670e-e rog strix

When you install the chipset drivers it makes a folder on your boot drive containing installers for every driver mine is:
C:\AMD\Chipset_Software\Packages\IODriver.


This should be the driver you are missing:
C:\AMD\Chipset_Software\Packages\IODriver\PCI\AMD-PCI-Driver

rip didn't see the next page.

Hey, curious about this, how high are most people getting on BCLK OCs? Skatterbencher's dual ccd (x3D) video goes to 104 while the single ccd video goes to 107, what's the peak BCLK people have been reaching?

 

[yzonker]

Ok, gotta set this straight. I went through and reset every CP2077 setting to default because I thought my result was too high. Not sure what it was. I thought it might be the crowd density, but it was showing "high" before. But maybe it wasn't really set? CP is known for being squirrely with settings.

Anyway, this is still with my daily config of 5.9Ghz, 4200CL15 DDR4. Shows DDR4 is still pretty competitive at least.

 

[xSneak]

I can't figure out how to get eCLK on my mobo so i'm using CO instead. Currently at -25 CO. How far have you guys been able to go with your offest ?

 

[Evelyn2023]

VBS should on or not? Cuz I'm still missing that PCI after change to UEFI mode.

61

I turned on SVM mode which enabled virtualization in Windows 10, didn't work for showing hte PCI driver, then I enabled VBS and still didn't see the PCI driver, I also tried that UEFI mode in the Secure Boot options and it still isn't listed. I can't get it to show up as an install option, apparently because the devices that it's a driver for are not present on my system.

@dexterhines would you mind exporting your bios settings to a text file so I can compare to my Asus X670e-e? You would plug in a USB drive, go to bios -> tools -> ez flash, then here at the bottom it should say "press f2 to save file" and also has a ctrl+f2 option, one of them saves a text file of all the bios options, the second one saves a CMO file (the actual bios file you could restore), with the text file I could compare to mine and see if you have some device enabled that's disabled on mine. I attached mine, settings as of yesterday.

 

[wmdieselmc]

I left one of the chips running prime from the "quick bins" just to show the level of accuracy of binning analysis and to get a broader scope on sustained clocks.
Once your familiar with the particular set of memory your using and mother board it's super easy to nail it.

Quick bin analysis

To 24 hours through prime blend. As we can see sustained avg clocks settled roughly 50 mhz lower.

One of the games that was choppy as hell on 7900x.

Chased a boss naked with a club and spammed 360 degree turns as those were what made it choppy. Max settings 1440P RT on. FPS cap so...frame times is what I wanted to see. Smooth now. Couple spikes probably when I hit boss then dodge rolled away.

I manage to install AMD PCI. Here what I did

SVM Mode -> Disable
Integrated Graphics -> Disable
Os Type -> Windows UEFI Mode

Integrated Graphics was the culprit I guess. Turn if on again my AMD PCI missing. Then disable it shows up.

Yes!
That was the culprit, although I don't see any real performance gains with PCI device driver installed tbh

Cheers for the correction dude, I did not even bother trying to beat the last score as it was too far ahead. I know CP is a dog with the settings too.
