P3D running but CPU not running at max speed

Recommended Posts

New PC (specs in sig) running P3D v4.3. With the aircraft at cruise I brought up the Task Manager and switched to the Performance tab. I expected to see the CPU running at it's maximum overclocked speed of 5.0Ghz. But it was only around 4.3Ghz. Why?

Is that utility a valid check of CPU speed or should I be using something else?

Hi Ray

I think Task Manager doesn't show the overclocked speed. I use a utility called CPU ID (one of many available), which shows information about the CPU, including the actual overclocked speed.

My new PC confused me initially, as the speed shown in this utility jumped up and down. This was due to a resource saving function - when required - ie under load,  the CPU remains at its maximum overclocked speed.

There are other utilities which will show you CPU and GPU temperatures as well as speed - you can watch these as you fly low over detailed scenery!

Best regards

Mike

Ray,

I have a i5 6600K OC at 4.5GHz (All core) and Windows 10 Task Manager, CPU-Z and Core Temp all report it at 4.5GHz. May be there is something wrong with your overclock. Just a thought.

 The CPU speed shown in the task manager does show the current speed including overclock but keep in mind as well that it's only showing one of the cores as they don't all overclock to the same frequency (common at least with newer Intel CPU's unless specifically set to do so in the bios).

Thanks gents. Mike, I will install CPU-Z and see what it reports.

Normand, this is a professionally  built (and overclocked) PC. I’ll install CPU-Z first and see how it compares to the TM. Maybe they have set something in the BIOS.

More tomorrow.

Ah, thanks. I suspect it’s taking an average of all virtual cores but if I recall correctly only 0 and 1 run at 5.0.

Is the CPU manually overclocked, or is it relying on Turbo to boost the speed?  Also, what are the system specs?

I’m guessing that it’s using Turbo. But I’m no expert which is why I bought from people who are. System specs in my sig.

When you view in task manager, the percentage your CPU is running at is converted to the freq

Perhaps you meant to say, why is P3d not running at 100%?

Fab, Ray. I'll be following in most respects, except the case.

Ray,

Can you be more specific when you say "around" 4.3 please. Is it stable @ 4.3 or fluctuating up and down?

Is it possible to see what % individual processes are running at?

Anyway, I believe Dave has given me the answer. Only the first two cores of the 8086K run at 5Ghz, the others run slower so the net result is something between 4 and 5.

Alex, the figure varied. Not constant.

Going to use my already good case, the Antec Ninehundred Two.

Ray,

Even they OC the system to 5.0 and you show those fluctuations on CPU you still need  to change a few things to have the CPU not fluctuating ( especially if you chose to have higher settings in P3D). Those fluctuatings on CPU at higher settings will give you stutters  :

control panel

power options

select to high performance and click on "change plan settings"

click on change advanced power settings

expand processor power managment

check minimum processor state to 100%

check system cooling policy setting to active

maximum processor state setting to 100 %.

If all the above will give satisfactory results will stop here. If is still fluctuating we need to check what you have in BIOS, not complicating at all.

As you can notice I have almost the same system.

Sorry, I was on the mobile site and it did not show your signature.  It sounds like they are relying on the stock Turbo to dynamically clock your CPU to 5.0 under light or single-threaded workloads.  The 8086k and 8700k both only run at 4.3 when 4 or more cores are heavily loaded.  I could tell you how to OC all cores to 5.0 but you would have to be comfortable going into your motherboards BIOS and changing some settings.

During a flight yesterday I was watching for stutters and there were none. Smooth as a baby's bottom.

I will check those settings but as I said yesterday the CPU fluctuation is almost certainly down to all virtual processors being clumped together and giving an average reading. Chillblast are a company with a high reputation and many awards so I would expect their PCs to be configured optimally.

That is not something I would be comfortable doing. I was told not to update the BIOS too as they have configured things with the current one. Performance is fine so I'm not unduly worried.

Sounds to me like they don’t have sync all cores turned on in the bios. That is step one for overclocking. It also sounds like nothing has been overclocked at all since that cpu defaults to 5ghz on a single core anyway. You sure these guys did any overclocking at all? Seems like a basic default bios config to me.

Looks ace, Ray. Glad I too now got that CPU.

I don't see any "sigs" here. Is that an option somewhere? I assume you have your new PC up and running. But P3D4? So no Concorde at present?

Took me a while to find that option! Your account > account settings > signature.  There you can move the slider to view signatures.

Ah, thanks! But my "account settings" has no entry called "signature" -- I had to also get a drop down called "settings area" viewed.

But there you have the facility to add your own signature (I don't have one), no slider, just a checkbox saying "View signatures?" above and "Show other people's signatures alongside their content" below. the checkbox is already on, but ... no signatures! Very strange.

Never mind. What I've never seen I won't miss.

Hi Pete,

I see the sig option has been answered. I did wonder if it might be adblocker.

Yes, new PC up and running and some very impressive fps but I still have to add an Ai package - probably UT Live. Worst fps were at Schiphol (30fps) but I do have my settings pretty high.

I thought long and hard about when to upgrade but being able to sell my old computer for a decent price was key. I intend to install P3D v3.4 just for Concorde and copy my scenery.cfg over and amend the paths. Some addons will also need copying but I'll leave that for a few days whilst I tweak things and enjoy a few flights.
