Cpu is slower after windows 10.

[Khronotos]

I was running windows 7 on this PC, and I upgraded to windows 10. While I was running on windows 7 my cpu was running at its base speed of 2.67ghz roughly 2.70 at all times and when I upgraded to windows 10 it seems to be thermal throttling itself even though nothing changed within that time period. It has the same cooling and the same fan speed etc. I even tried cleaning it with electronic duster(s) everything is the same. I tried turning off the Intel speedstep to see if maybe for some reason it was malfunctioning from the motherboard being extremely old, but that just made the computer crash when running a game. I tried a bunch of fixes nothing worked I am not sure if the thermal paste somehow died within that time frame or what.

 

I am running a Intel i7 920 2.67GHz and the motherboard is a Phoenix - AwardBIOS v6.00PG

How do you determine that?

[Khronotos]

The CPU is capped at 1.65ghz constantly even under the resource monitor its max'd at 59%

Check your power-settings.

[Khronotos]

I have set my power settings to high performance and set the max at 100% I am on a desktop as well so no battery/charging

Download OCCT and run the occt check also check the voltages and the temperatures and tell us what you see (or put screenshots) 

[Khronotos]

This is what it looks like in my task manager/resource monitor

[papajo]

yea ok download occt and run the test please 

[Khronotos]

[papajo]

well for one your FAN is very slow maybe dying an your temps are very high run the test for more than 10 minutes and take a screenshot (has a camera icon thingy for that on the top right) and have only the frequencies graph so I can better see the core fluctuations. 

[Khronotos]

After 11 minutes this is the frequencies 

[papajo]

As said you get very high temps and low fan speed which indicates that something is wrong with your cooling..

 

Having said that I dont see any frequency fluctuations which makes me believe there is at least something else here at play disable all the power saving options from your bios including C1 state. 

[Khronotos]

Doing that causes my computer to turn off with any stress, I've tried it 3 times

 

[papajo]

well that's it then  a) restore bios to default settings b) change your CPU cooler  (And clean the lid and apply new paste, for a cheaper approach you could just try reapply the cooling paste and reseat the cooler but its probably dead or the port that supplies your cooler wit power is dying because cooler has too low RPM )

Fair enough, Thank you for the help!

Your screenshot shows that your CPU is locked to the lowest speed even when your CPU temperatures are only 60°C, 70°C, 80°C.  Thermal throttling does not start until your CPU reaches a core temperature of 100°C so that eliminates thermal throttling as the cause.

 

Go into the BIOS and make sure SpeedStep and Intel Turbo Boost are enabled.  Boot up and try running CPU-Z.  If your CPU is still stuck, try running ThrottleStop 8.70.6.

Make sure that it shows that SpeedStep is enabled.  Check the Set Multiplier option and set that to the maximum value.  Now push the Turn On button to take ThrottleStop out of Monitoring mode.  Open up the built in TS Bench test, set this to 1 Thread, start the test and post a screenshot of ThrottleStop while this test is running.  A 1 Thread test will confirm your maximum multiplier without the temperatures getting too high.

 

If you want access to the 22 multiplier that this CPU supports when 1 core is active, you need to enable the C3 or C6 C state in the BIOS.  Disabling the C states in the BIOS also disables the 22 multiplier.  ThrottleStop can report what C states your CPU is using when idle.  If you are still having problems, post some screenshots so I can tell you how to get ThrottleStop setup correctly.

CPU is running at 1.6GHz and gets close to 100C while the fan is at 900RPM also says that when he tries to disable thermal/power state controls his system crashes so he has to fix that issue first probably the CPU is locked at that because of this issue.

CPUs do not start thermal throttling before they get to 100°C.  Look at the graphs.  The CPU speed is flat lined at its minimum before the CPU has a chance to warm up.

@papajoIf you look back at the first post, this problem first happened after switching from Windows 7 to Windows 10.  That means that something in the BIOS like SpeedStep is not set right.  This problem might have prevented Windows 10 from setting the CPU up correctly.  It has nothing to do with temperatures.

 

If the CPU is crashing while loaded, it is likely because it is not getting enough voltage.  That needs to be checked in the BIOS.  A CPU-Z screenshot while the CPU is loaded will confirm what voltage the CPU is actually getting.  The 22 multiplier that these CPUs can use will cause instability problems if the BIOS is not setup correctly.

It has everything to do with temperatures... this cpu should not even come close to 50c @ 1,6 Ghz and the fan speed should be more than 900 RPM... <--- this here is a major issue the other issues whatsoever may or may not exist and are secondary...

 

Its like you have a man who says he doesnt feel well and he started sneezing but also bleeds tons of blood through a cut he has and you are like "he says he was sneezing and now with the corona virus outbreak he probably should test if he is positive" nope he should take care first of the bleeding corona virus positive or negative is secondary....

@unclewebb Hey, sorry just saw this thought I was pretty much done here. But I did test what you said in doing that starting up something caused each core to raise to 100c with any stress at all I do believe it's a heat issue, I idle at about 55-60c with only youtube running this processor hasn't been toyed with in a very long time. -Edit. although I was able to use throttle stop to get abit of a enchancement on performance for now whilst I am in progress for getting new fans ect. So thank you for your input aswell!

 

 

This is what seems to be "working" for me, still not maxed out but im not reaching 100c everytime I start a game but this is the usage im getting while idle

Υοu need to take care of the thermal issue asap it could end up frying your chip

 

The first thing you should have done is to apply paste and reseat the cooler then even better to borrow and test an other cooler because maybe your mobo is malfunctioning not running the fans and not running the CPU at the power states it should run. 

 

Have you tried to reset the bios to factory defaults as I said ?  This way we can check if the heat problem is cause by a voltage setting or something similar 

[Khronotos]

@papajo I have factory reset it yes, Does nothing to change it. I am going to fix the thermal issue sometime, but I live in NY not as simple as going to the store right now. my cpu does not reach 100c all the time only when I raised the throttling. it is currently at 72c while playing games while throttled it'll be fine untill I can go out and get what I need. Thank you for the help I will fix this issue once I am able to
