Hey all,

 

I am currently using an intel core i9-10900X cpu with 10 cores. In task manager the CPU usage never goes above 60% when I allocate 10 cores to a job. I am just wondering if it is safe to allocate some of the virtual "cores" to my program. I have been staying on the safe side only allocating 10 and leaving the virtual cores to handle background stuff, but if it is safe to do so, I wouldn't mind allocating a few of those to speed up the calculation. 

 

EDIT: It has 10 cores and 20 logical processors - sorry for any confusion. My question remains - is it okay to allocate more than 10 to a job, or should I leave them empty?

 

Also - it appears that the IT department enabled overclocking. During jobs the CPU runs at max capacity until completed, and as such, I am worried that continuously overclocking the CPU will cause issues in the future (the temperature is ALWAYS hovering very close to max temp). The base speed is 3.70 GHz, but it consistently runs at 3.90 - 4.05 GHz. Is this something to be concerned about? 

 

Thanks a bunch 🙂

The extra threads are not "virtual cores", they actually allow the cores to take multiple work at once since each core has multiple compute units. The only reason to not use all threads is that full CPU usage could make the OS unresponsive.

This is just the turbo boost function, part of the default behavior from Intel. Under ideal conditions (i.e. high enough power limit and low enough temperature) the all core turbo is 4.3GHz, while in low thread count work it can go even further.

 

What is the "max temp" you're talking about?

"max temp" was a bad descriptor, my apologies. What I meant is that the CPU temperature is always around 95-97C - I am not sure if this is considered "hot", or if it is normal.

 

As for the processing units - I assume that it is safe to allocate 16 to a single job, leaving 4 to run background OS stuff. 

 

Thank you 🙂

95-97 is rather hot. And yes 4 spare should be more than enough

Yup hot (hard throttle point is 100C), probably why it didnt reach all core turbo
