If CCD0 is the one with the V-cache then I have issues, as all my games seem to default to running on the 8 cores of CCD1 and according to Ryzen Master all the cores on CCD0 are sleeping. Latest BIOS and all chipset drivers including the 3DVcache optimizer are installed.

Make sure you have Game Mode and Game Bar turned on in Settings and you are on the Balanced power plan (don't think this is strictly required). Mine was doing what yours is doing until I re-enabled Game Mode.

Turns out that despite being set to automatically start, the AMD 3D V-Cache Performance Optimizer Service was not starting. As soon as I started it manually everything started working as it should.

Time to look at why it doesn't start when it should.

with all these 9800X3d Cpus that still seem to be failing, is anyone taking precautions and under volting etc I haven't seen any reported cases with the 9950x3D but has be a wee bity worried especially running the Asrock x870e Nova

I have the Nova but not adjusted anything in the BIOS for the CPU but I have enabled EXPO and have checked SOC and VCore and its seems to be within check.

This is what mine looks like completely stock with EXPO enabled - CL30 6000Mhz

The 9950 X3D with decent ram speeds, more than halved my noise reduction time in lightroom versus my X3900 and slow ram

Very happy... 113 images in 14 minutes, which is a perfect time window to get showered and dressed, then finish the export.

Have there been any major issues with specific motherboards that people have tried this CPU with?

Saw others mention asrock issues.

Think I’m just going with this in new build with 9950x3d and 5080

Looks like setting it to delayed start has sorted this.

AsRock no real issues

Getting windows to install was a PITA, one of those problem is that it needed a LAN driver to continue install. Fortunately I could use my wife's laptop to get the EXE driver and winrar to extract it to a usb stick and continue my windows install..

But a friend with the same board and doing a windows install say he didn't get the same thing, so not really a board thing.

Okay thanks!

I thought I saw somewhere else that asrock had issues.

Maybe I don’t need to change from the asrock 870 rs then, although it’s white so might get a black motherboard instead - the gigabyte one above or the

ASUS ROG STRIX B650E-F GAMING WIFI​

OCUK are building it for me so hopefully they can figure out windows

J2C did a video a few days ago and showed that changing the power plan from balanced can override the new BIOS/firmware leaving all cores functional ( which is what you don't want ).

Yes, I did think it was required or at least highly recommended then some comments elsewhere on the web said it wasn't a requirement and should work the same with either plan. I would stick to balanced then you know it isn't that being a possible cause for parking not working correctly.

What is AMD 3D V-Cache Performance Optimizer Service? I have the latest AMD chipset but don't know how you enable this? I've simply left all 16 cores running with -20 on CCD0 and -25 on CCD1

The E-E is a much better board than the E-F

Edit: Jeez can't believe the E-E is £310 now and £100 more than the E-F. When I got mine last August the E-E was £230 and only £10 more than the E-F.
Supply and demand I guess

The service installs and runs automatically from the chipset driver. You shouldn't need to touch it if core parking is working as it should.

I haven't enabled core parking. My Asus bios has 2 settings - one that disables CCD 1 and another that puts CCD 1 to sleep, I believe.

I simply left all 16 cores enabled. Should I use the sleep option which is what I presume 3D V-Cache Performance Optimizer Service is?

It will automatically take care of it if you have the latest bios and chipset drivers. It requires no interaction from you under normal circumstances.

I treat core parking, apps being assigned to the right CCD like I treat my wife. I ignore it and more often that not I forget about it....

As mentioned, don't touch any settings in the BIOS that disables or sleeps cores. That will all be handled in Windows automatically.

That’s because you installed windows 11 right? And your friend didn’t have any issues as he installed windows 10…
