Cpu frequency locked in

[oelholm]

Hi, so as far as i can remember (1+ yr) my cpu has been locked at 4.68 ghz. Whatever i do it never changes its frequency. Im not sure if i have somehow manually locked it or if its some sort of bug/feature. Thanks

Unrelated, but I've move that GPU to the top slot so it cna run at x16 for the best performance.

A couple things:

1. Use HWInfo or CPU-Z to read the CPU frequency, other software (Task Manager specifically) has been known to bug and give false readings. 
2. What motherboard do you have? If it's a B460/B560 board, that will cause your issue as those boards do not support CPU overclocking.
3. Move your GPU to the top x16 slot, that's the slot optimized for PCIe bandwidth, meaning that at best you're losing 1-2% performance, and at worse you're losing 40-50% performance.

i do indeed have a B460 board, and sadly im pretty sure that top slot is basically dead. gpu stopped working some time ago, changed the slot and now its working, dont really wanna mess with it as i havent noticed any significant performance loss.

Specs are: i7 10700KF, B460, rtx 3070, 16 gb ddr4 3200 mhz

We need to know what make and model the board is, not just it's a B460 board.
There are several different makes and models of a B460 and the exact one you have will matter in figuring out a solution.

oh yeah, sorry mb. Its an Asus TUF gaming b460 PLUS

what's that other card in the top slot though? does it work?

That is a wifi card and it works perfectly. its sat in a separate x4 slot

it honestly might be the reason why the GPU can't be in first slot, but don't quote me on that, I'm just assuming based on official Intel stats for 10700KF:

As far as CPU running on constant 4,something Ghz, still better than running locked on 3,8Ghz base, you have performance but you also don't suffer from thermal problems, though that AIO might be able to handle this CPU at it's peak performance

It ran fine with the graphics card in the top slot for almost 3 years, then one day it just said nah. Im pretty sure theres something up with my motherboard as i first had some very, very weird ram issues and then right after the issue with the gpu.

If you are using the Windows High Performance power plan and the C states are all disabled, your CPU will be locked to a fixed frequency whether idle or fully loaded. That is not a bad thing. Use the Windows Balanced power plan if you want to see your CPU slow down when lightly loaded. 

 

For Intel Turbo Boost to work correctly, the core C states need to be enabled in the BIOS. Most monitoring software does not accurately report Intel Turbo Boost on B series motherboards. Try using ThrottleStop 9.6. It uses high performance monitoring timers within the CPU and closely follows the Intel recommended monitoring method.  

 

https://www.techpowerup.com/download/techpowerup-throttlestop/

 

When idle at the desktop, open the C states window to check if the C states are enabled. It should look something like this with idle cores spending close to 99% of their time in core C7. 

 

 

If this window shows all 0.0, Intel Turbo Boost will not fully work. If Intel Turbo Boost is enabled and working correctly, ThrottleStop should show a CPU speed higher than 4.68 GHz during a single thread CPU test. Try running the ThrottleStop TS Bench test. Set it to 1 Thread. You can also run the single core test in Cinebench to create a consistent one core load. Do not use the CPU-Z Single Thread test. It loads two cores, not one. Take a ThrottleStop screenshot while you are running a single thread test. 

 

If you have any problems, post screenshots of ThrottleStop including the FIVR and TPL windows. It will show if the BIOS is setting up your CPU correctly. Turn off all of those other monitoring apps when testing. They are not accurate enough to report Intel Turbo Boost correctly.

So, i went in the bios and the C states option was set to auto, changed it to enabled. Still it never went over 4.7 ghz even in the 1 thread benchmark.

That is usually a sign that the BIOS is not setting your CPU correctly. Are you using the latest BIOS version?

 

In ThrottleStop try checking the MMIO Lock box which is near the top right of the Turbo Power Limits window. Also check the Speed Shift box in this window. 

 

Post a screenshot of the Limit Reasons window while you are running the 1 Thread test.

well i updated my BIOS yesterday so i dont think thats the issue. I tried what you said and ran the bench but still nothing

The BIOS can set the maximum multiplier for the CPU. It is the most likely issue. If the BIOS has set the maximum multiplier to 47, that would limit your CPU to the 47 multiplier. BIOS bugs are common. 

 

There is also a different setting within the Windows power plan that can be used to limit the maximum CPU speed. Here is how to add access to the Maximum processor frequency variable to your Windows power plan.

 

https://www.majorgeeks.com/content/page/how_to_add_or_remove_maximum_processor_frequency.html

 

The default value of 0 should allow the CPU to reach its maximum speed. If the Maximum processor frequency is set to 0 then it is very likely a BIOS issue.

 

In ThrottleStop the PP0 Power Limit does not need to be checked. You can set the PP0 Turbo Time Limit to the minimum, 0.0010 seconds. This does not seem to be causing the problem you are having. 

 

Edit - If you have access to RW Everything, post a screenshot of the Memory tab with the Address set to FED15900

That will show if your motherboard is using this method to limit the CPU speed.

So i changed the PP0 Turbo Time Limit to 0.0010 but like you said didnt change anything.  The power plan thing was already set to 0 andI tried to get RW everything but the newest version seems to be from 2017 and doesnt support my hardware.
