Hello everyone
Windows 10
Ryzen 5900X
RTX 3070 Ti
64 Go RAM G.Skill F4 3600 C16
MSI b550 Tomahawk
Bug or problem, I can’t really define it.
I notice that some models (I see on Gaia and Nyx) use only 1 CCX (core 0>5)
It’s an issue for confort, temp regulation use global temp, only use 1 CCX up global temps for nothing.
It’s a performance issue when i do other task when Topaz video AI is working, the other task who use all CPU core are limited because Topaz Video AI saturated half of my first 6 core.
It’s a bug or a lack of optimisation, but it’s an unfortunate issue.

In our testing we’ve found that spreading to about half of the CPU cores is the optimal setting for most systems. This prevents over-utilization and system unresponsiveness during processing.
Your optimisation is impeccable for single chiplet CPUs.
At the moment my 5900 is being used as a 3600 and personally I use my computer while Topaz Video is running.
When I’m using rendering software, especially 3D, it’s catastrophic in terms of both performance and temperature, where on average I’m 7 degrees warmer because of this truncated CPU usage.
As far as performance is concerned, I simply freeze at every action, which I didn’t have before.
On my side I can’t do any better, it’s already UV at -150Mv with a lower maximum power consumption, I can’t do any more without dropping performance enormously or even losing stability.
As far as possible, I’d like a choice equivalent to the GPU choice we have:
That I could have a “non-recommended” CPU usage choice that uses my processor as a 2 chiplet processor and not 1.
I know that the Ryzen 2 chiplet architecture is no joy to optimise, I’m not dreaming of something perfect, but it would be very much appreciated if a minimum effort could be made to load the CCX 1 a little more (as opposed to very little at present).
The V2 was 2/3-1/3 use CPU CCX and it was so better compare that V4
