Re: Stuck on E-cores for CPU workload on 12th gen Core i7, W11 22H2

Background and foreground processes shouldn't have anything to do with affinities. It's only based on process priority in Windows scheduler and some black magic that only Microsoft understands. As stated multiple times in threads about big.LITTLE CPUs, the fix is to set the CPU slot to use the numb...

Re: Stuck on E-cores for CPU workload on 12th gen Core i7, W11 22H2

I heard that Windows scheduler is based on process priority to assign to P-cores or E-cores ... try to set FahCore priority to Normal in task manager and see if that helps ... Doesn't work, From what I understand it's a hybrid between white listing and foreground/background switching. FAH CPU worke...

Re: Stuck on E-cores for CPU workload on 11th gen Core i7, W11 22H2

On big.LITTLE CPUs, the first thing to do is to manually set the number of threads of the CPU folding slot to match the number of threads of P-cores. If Windows is still messing around with its scheduler after doing this, you might need a tool like Process Lasso to handle the affinity management au...

Hate to be that guy but intel 11th gen processors don’t have big core, little core architecture. https://www.intel.com/content/www/us/en/products/sku/212047/intel-core-i711700k-processor-16m-cache-up-to-5-00-ghz/specifications.html Only 12th gen and up have that architecture. https://www.intel.com/...

Stuck on E-cores for CPU workload on 12th gen Core i7, W11 22H2

Hi all, Title says it, on a PC with both P-cores and E-cores, such as 12700K, workload always got scheduled to E-cores, wasting at least 70% of available power. Setting fold power or core slot has no effect, the only workaround is to set "processor affinity" for the CPU workload process to...
