Thanks Jussi for the tip. After some Googling it seems that the models I have been looking at (7900X, 7950X, 9900X) are symmetric per your comment. The processors with an X3D suffix (e.g. 7950X3D) seem to have the asymmetric design with the two CCDs not identical. Good to know!
I’m recommending my dad goes for the 7950X.

Any ideas?
I updated here permissions, but still error
Fixed! somehow it was running on background. After closing it, it was able to install it
That 5080 card is really something when overclocked. DSD64-512 doesn’t even make it break a sweat, even with all the bells and whistles on, including convolution. DSD256-512 at least managed to get the GPU temps up to 45°C, but its usage was still only around 10%. 
That will indeed cause errors writing many of the files. In addition, on Windows it is recommended to uninstall the old version before installing a new one. Please note that this won’t touch your settings, library, or license key file!
Many thanks! Actually I rarely use this version, it’s on my dual boot pc, mostly the windows boot is for gaming and the Ubuntu boot for music 
.
Another question, I recently installed NVIDIA-575-Open driver in Ubuntu, it was done using the “.run” installation. ( before installing I removed and purge previous nvidia drivers). It was working fine but, after running some Ubuntu updates using the updating app it was updated to a repository 570 ver and I had to clean and install it again. Any suggestions of what to update and what not to update so is not affected? Like (unchecked any option)
Many thanks for your support 
BTW, Is this a good idea:
I recommend to install the drivers as proper packages from Nvidia’s CUDA repository. Then you know you are in sync. Those .run installers are problematic since they mess with the OS configuration outside of the packaging system, which will in turn cause breakage when the packaging system updates packages and doesn’t know about these changes.
So first add the Nvidia repository:
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2404/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt update
Then if you are on Ubuntu Desktop (IOW, with GUI, which I assume being the case on HQPlayer Desktop thread):
sudo apt install nvidia-open
Then reboot and you should be done. You’ll get driver updates along with the OS updates.
Yes! Many thanks. Also running embedded here.
Will do a
.run — uninstall
Purge Delete all nvidia drivers
sudo apt-get remove --purge ‘^nvidia-.*’
sudo apt-get remove --purge ‘^libnvidia-.*’
sudo apt-get remove --purge ‘^cuda-.*’
sudo apt install build-essential
Then follow your steps
Done! Fully integrated into the Ubuntu Desktop Updater! Many Thanks!
Just wanted to say that I did finally get DSD1024 stable with sincL and asdm7ec-super 512+. Still running same kf-14900 and 4090 on Ubuntu.
It is rather embarrassing - at the end of the day I just asked Claude Code to observe playback for dropouts and design any fixes to configuration apply any tuning it thought reasonable to free up cores 0 and 4. It cooked up a thermal optimization application, some priority stuff, something to do with hugepages - I think 7 distinct changes in total - and this totally gave me stable playback for the first time at this spec.
So to anyone else out there who is stuck and desperate and wants a fresh whack at this - give Claude Code a shot at it. I think some of those adjustments might have helped out with avx handling in particular.
Don’t get me wrong - I still have a tailored overclock and all that. But at the end of the day, it didn’t require any mad stupid GHz or subambient cooling or any such silly business. Though I did try a bit of that.
Running a modest undervolt, 800 vrm, 46 ring ratio, avx offset 2, cores 0 and 4 yoked to 5.9 (down to 5.4 under heavy load). 360 aio cooling running hard.
Oh and the Holo Cyan 2 is like off the charts good compared to Gustard r26 and denafrips Pontus 2. Inky black silences, more detail than I’ve heard from anything else.

Really looking forward to sampling all the modulators and filters again with an open mind.
You really feel smart again when you spend over an hour wondering why DSD playback feels so much heavier, only to finally realize the 20kHz filter was the reason…
