Thank you for joining the Processors community.
Please let review this matter, I will update the thread as soon as possible.
/thread/116311 iBruce, thank you for your patience.
I would like to let you know that this should be possible, and Turbo Boost should work having some cores disabled, but we strongly recommend using all cores to ensure correct functionality.
Turbo Boost 2.0 and 3.0 will still work perfectly with the 7820X with 2cores disabled?
Also, I only need to run the CPU stock with no overclock as long as I can depend on both Turbo Boosts 2.0 and 3.0 working correctly.
So, the thermal difference/delta running the 7820X with 6-cores or all 8-cores may not be enough to even warrant disabling two of the cores, if that is the case, I will happily run "all eight cores".
With my work, I don't benefit from the extra cores, but wanting the 7820X over the 7800X for the Turbo Boost 3.0 4.5GHz feature and the increased memory speed compatibility.
As mentioned before we strongly recommend using all cores to ensure correct functionality, but according to the information mentioned above, yes, Turbo Boost should work having some cores disabled.
