KVR Audio

Hey yall

I just got an Intel i5-14600k, an absolute beast of a CPU, to upgrade from an old Ryzen 5 3600x, and unfortunately it's been terrible for audio production

Loaded up a Bitwig project file containing one instance of a 3-voice Serum patch going into a distortion and reverb (Saturn 2 and Pro-R), a project file my last CPU had no problem handling, and the CPU meter spiked hard with unbearable underruns

Despite Bitwig spiking my cpu meter, my system monitor shows CPU at about 10-20% usage per core.

My CPU governor is set to Performance and my sample rate is at a modest 1024

Anyone more tech-literate than I know what's up with this? It feels like I'm producing on a 2011 macbook, Lol.

Thanks for any help

P.S. running Arch Linux with realtime-privileges. Tested previously on Mint with the same issue.

Try turning off E-cores in the BIOS for a test.

Usually good advice, but that's a Windows utility, and the OP does not run Windows:

Hello,
Make sure your motherboard BIOS is up to date and that your CPU is not overheating.
Updating the BIOS or not, clear the CMOS.

In the BIOS set:
Legacy USB Support = Disabled
XHCI Hand-off = Disabled

Try a different USB port and/or USB cable.
If it is ASRock motherboard, plug the USB DAC/audio interface in one of the yellow/orange ports.

Intel CPU generation 12/13/14(15 too?) have a tendency to bent.
This may lead to higher temperatures and strange problems...
I would try to reseat the CPU, *BETTER* get a Thermalright Contact Frame!

Also make sure the CPU socket does not have bent pins...

Terrible performance after a CPU upgrade
