Contrary to popular belief, we are not all-knowing-all-seeing magical beings!

If you want help you're going to have to provide lots of info. Like what is your hardware, what is your operating system, what version of GZDoom/LZDoom/whatever you're using, what mods you're loading, how you're loading it, what you've already tried for fixing the problem, and anything else that is even remotely relevant to the problem.

We can't magically figure out what it is if you're going to be vague, and if we feel like you're just wasting our time with guessing games we will act like that's what you're really doing and won't help you.

Intel turbo boost not maxed out.

Post by zdusr »

Hi

According to my CPU specs https://www.intel.com/content/www/us/en ... tions.html my CPU should go up to 4.7 GHz. However if I run doom on 1 monitor and view task manager on other monitor it seems to stay around 4.2 to 4.3 GHz. When I look at CPU temp then it stays around 50C so it should be far from thermal throttling. Is there something I can do to make it use full 4.7 GHz as advertised? My FPS count sits around 20-30 with ProfanePromiseland.wad (40k monsters) so this turbo boost thing should have plenty of reason to try to push my CPU to 4.7 GHz but it doesn't. Any hints? I am currently not using any graphics intensive mods such as brutal doom or russian overkill so I don't think It's waiting behind my GPU (Intel UHD-630) to finish rendering.

As far as I know (keep in mind that I have no idea how Turbo Boost actually works) - it should be unlocked as long as the operating system is giving the CPU the ability to run at full (100%) speed.

This is one reason why I lock my CPU's often at 99% speed, is to actually prevent Turbo Boost from actually working - because I want to keep the system cool at all times. I always keep a preset available to run at 100% speed if I actually do want/need it, like for an intense gaming session, but that's extremely rare, for me.

With Windows it is managed in the power management (start->run->powercfg.cpl) - using this you can use the "High Performance" preset to force the system to run at full throttle 100% of the time.

With Linux it is controlled by processor governor - and I do not know of what exact GUI power management tools are available here, but here is where a Google Search might turn up handy. This is the first result that came up, for me: https://ubuntuhandbook.org/index.php/20 ... frequency/

You should be able to run the CPU safely well into the 70's and 80's without any issue, though - at 50 C you definitely are not utilizing your full core performance here.

That's actually useful to know. My Ryzen constantly runs noisy and doesn't offer much performance benefit. Changing that has made it noticeably quieter.

Thanks for the info, I did not know that you can control this thing so easily. Thought I needed some intel proprietary software. Is this start->run->powercfg.cpl the only way you you manage this? If I go to Change plan settings > Change advanced power settings > Processor power management > Maximum processor state then it already shows 100% but CPU still maxes out around 4.3 GHz instead 4.7 GHz. I also changed my graphics settings to Maximum performance but it did not seem to have effect. But anyways I confirmed that this Maximum processor state works. I changed to to 30% and task manager actually showed 1.2 GHz so It's a clear proof that this indeed has effect. Was just wondering if I have to unlock something to get full turbo boost to advertised 4.7 GHz?

For the latest intel cpus the stock intel heatsink usually is not good enough, you need something better.

I already have something better. CPU temp doesnt get much above 50C which is well below thermal throttling temperature.


Update ✅: I had to download Intel® Extreme Tuning Utility. It allowed me to go full 4.7Ghz and even 5.

❓ Any ideas if running it 5 GHz will damage it? If the temperature did not go over 61 C then it means running 5GHz is also ok even if it goes beyond advertised turbo frequency (4.7 GHz)?

Update2 ❌: Running it above 4.7 GHz seems to be unstable.
