just out of interest - how many threads and cores are you folks seeing in Windows?

Did you update the BIOS on the new motherboard?

Is this a new Windows install or your old one that had the 8 core CPU? Could be a driver issue if it's the latter.

Run Ryzen Master, that should tell you for sure if the system is seeing 16 cores.

Yep, BIOS updated.

Old windows install that had my 7800X3D
I will update ryzen master - its currently saying it's not a supported CPU when I try to open it.

Edit - so Ryzen Master now wont install... this is going well isn't it !!



Thats what I'm seeing in Windows

Remove and reinstall Ryzen Master. It might have Game Mode turned on or something. Also make sure your power plan in Windows is set to Balanced. I don't think that would affect core count but core parking does rely on it.

I've done that - this is what is now happening when I try to load it...



Power plan is set to balanced again.

Just so I've shown my bios incase I've got it wrong

 
Guess who forgot to update bios before installing Cpu. I downloaded it a couple of days ago but forgot to put it on a USB stick and I don't have any other USB A devices to do it that way.
I could get into the old Bios, but of course it would not boot into windows.

Anyway tried just installing it from the NVME through bios and it flashed fine! Really surprised, so all up and running now

I'm back in the game !

It was my motherboard. I, err, bent the socket pins.

New board working beautifully !

Edit - hang on ....

Anyone else only seeing 8 cores and 16 threads in Windows (Task Manager, Cinebench, HW Monitor, CPUID) ... ? All 32 "processors" are shown in Device Manager, and its showing there as

I've checked the bios and the turbo mode is disabled.... any ideas?

Yes, windows 11, patched to latest, latest chipset drivers, latest bios on my motherboard.

Nope, but you bent the pins...

Cinebench R23

Base = 41444
-20 = 43960
-30 = 44222 (temps 79-81, noctua D15)

So do I just do 85 and -40 and see how it goes from here? anything else I should look at?

(extra)

85 -40 - Crashed as I started Cinebench
75 -30 - 43899 (CPU temp kept to 75)

Its a funny benchmark really as its just the in game for for Tom Clancy the division 2, but its a game I play with friends.

Not a bad jump from a 7800X3D to a 9950X3D ...

All I've done is enable XMP - as you can see from above, I've had plenty of other challenges before any tuning !!

I'm no major over/under clocker but from what I remember, you also have to pay attention to idle as the voltage can go too low and crash the system. When I played with CO on my 7950x, whenever it crashed, it was always at idle, never under load.
