Setting turbo

[muletopia (Chris)]

Hello,
I have a Lenovo T490s laptop which runs at 1.9 ghtz
I guess that is turbo level 1. The max turbo is 4 for this device. Does anyone know how to set a turbo level?

Hi chris...
This explains the process pretty well for w10 and w11...

Note that this only sets what the maximum is - the CPU 'decides' whether it needs to go into turbo mode, and by how much, taking into account thermal management.
you can't just 'force' it....unless you have a cpu that can be overclocked....

personally - setting my old pc to 'performance' can result in instability - so i just leave it in 'balanced'

I'm not even sure if performance mode actually gives me anything - i dont use my pc for gaming, so FPS on the screen is not important....
my biggest consumers of CPU are deep sky stacker and Siril - and for these apps, it seems to make no difference...

Cheers,

Thanks for your information Sharkbite,
I use Siril occasionally, most often Astropixelprocesser, that program uses all available threads,maybe turbo does not matter for APP.
My main reason for wanting turbo is for mathematical modelling, which may go to multi threading.
All up upping turbo may not be worth while.

Hi Chris,

I think what you're seeing is the CPU being in 'low power' mode when not doing anything. It should ramp up to full speed when doing work.

If you open the Windows Task Manager (hit CTRL-ALT-DEL and select Task Manager from the list of options) and then the second tab along (Performance???) you can see pretty graphs of your machine's activities.

Selecting the CPU option on the left will show raw numbers across the bottom of the window, including the CPU's current speed.

Windows may also be throttling your CPU speed because of any power saving settings that are enabled. You may need to fiddle with these to get your machine running at it's full speed when required.

Cheers,

There's no point in me repeating what everyone else has said here so I'll leave that alone.
As to the multi-threading that is as I'm guessing you'd know dependant on available cores with many processors capable of 2 threads per core. My son has a LOT of server gear with 8 core processors (possibly higher, I lose track of it all) and we've tried utilising the high core/thread count capabilities for many a program only to find they don't work with multi threading applications and at best run on often a single core.
To say this is frustrating is an understatement.


Whenever I use DSS (or Registax I can't remember which astro software it is) I get the option to use multi cores on the processing but it always fails, selecting one core processing is the only way to get it to work. That could be a hardware issue but I do run a 4 core I7 processor with 8 thread capabilities and 32GB of RAM.
