X3D Turbo mode

[Dustbag1969]

Hi

I am running a AMD 7800X3D and I have read a lot recently about the new X3D turbo mode that has been introduced to some motherboards.
After updating my Bios I have this option but I wondered if anyone has tried this for DCS and if it gives any performance benefits?

Thanks

Anyone tried X3D turbo mode with DCS and any benefit. It seemed to make mine slower but i might have done it wrong

The only thing I heard about Turbo Mode (from Gigabyte motherboards) is that it's pretty much useless: you'd be better off with PBO. That's from someone on YouTube, I don't remember if it was Hardware Unboxed or Gamers Nexus.

7800x3d doesnt do PBO, you need a 9*** series for that mate.

Whoopsie, my bad then...

Anyway, the way I understand it is that Gigabyte's turbo mode basically just turns off SMT (and disables the 2nd CCD if present) and based on what I have seen of DCS's core management, I'm not sure that's a good idea. Over the years there have been forum posts about people who turn off SMT in DCS (either in BIOS or by using Project Lasso) and haven't seen any performance boost.

I think DCS is pretty good at spreading the workflow across available cores, and identifying which cores to use for render tasks and IO and stuff.
