How to properly undervolt i7 77OOHQ HP LAPTOP?

[sparrow1121]

Greetings i have hp pavilion 15-cb076tx. How to undervolt properly using trottlestop?

In the TPL window check the MMIO Lock box. Set Power Limit 4 to a value of 0.

Your laptop looks like it might have poor cooling. When was the last time you opened it up and cleaned it out? Blowing out the dust can help. Consider replacing the thermal paste if blowing out the dust does not help. Maybe your laptop is running hot because your room temperature is over 30°C.

In the FIVR window set IccMax for both the core and the cache to the max, 255.75. You can set the turbo ratios back to their default values; 38, 36, 35, 34. Your CPU does not support any overclocking so setting all of the turbo ratios to 38 will not accomplish anything.

If you have a Nvidia GPU, I would not undervolt the Intel GPU. It is usually not worth the bother and might cause instability if you go too far. If you do want to undervolt the Intel GPU then you also have to undervolt the iGPU Unslice the same amount. If you only undervolt one of these, on most CPUs, this will not actually do anything.

Try running the TS Bench 960M test. Does it report any errors? If you see any errors during this test or if your computer randomly crashes, I would increase the cache voltage. Setting the cache to -140 mV is usually right on the very edge of stability.

When stress testing your CPU seems to be throttling. Exit HWiNFO and post a screenshot while AIDA64 stress testing that includes ThrottleStop with Limit Reasons open.

Thank you for your reply mr unclewebb.
1) i set "power limit 4 " to 0,
2) i turned off Intel GPU because i have nvidia gtx 1050 2gb,
3)IccMax is now 255.75,
4) i tried TS Bench 960M test and everithing is fine,
5) yes i think i need to clean my laptop ,
6)what about long power and short power ? shoud i increase or decrease .
7) what else can i try with my laptop ?

 

[unclewebb]

what about long power and short power ? should I increase or decrease

You can try doing whatever you like to these limits. What are you trying to accomplish? Higher performance or less heat? There is probably no point in increasing the turbo power limits if your cooling cannot manage the extra heat that it will create.

i tried TS Bench 960M test and everithing is fine

I find that is a quick basic test to see if the voltage is more or less stable. If you have any problems with games randomly crashing then try adding 10 mV of voltage to the cache. It is the most important adjustment for stability issues. The rest of your settings look OK.

I'm trying to find best point for high performance and less heat .now i have cpu core -250 and cache -140 and everithing is stable exept some games are crashing,

 

[unclewebb]

cache -140 and everything is stable exept some games are crashing,

If some games are crashing then you are not stable. Set the cache to something more conservative like an offset of -130 mV.

i will do it . thank you sir.

unclewebb i have another question . when im using trottlestop in battery mode laptop is stucking .how to fix that problem?

 

[unclewebb]

What does stucking mean? The screenshot you posted shows that your computer is running OK. Post a screenshot that shows the problem and attach a log file.

The CPU is running too hot. Open your laptop and fix the cooling problem.

 

[sparrow1121]

I tired to fix temperature problem , i changed thermal past and now i think its better. Problem is that ,when im unplugging charger trottlestop is stopping working, after plug in again i must open trottlestop again to start.

If ThrottleStop crashes when you unplug your laptop, it is because you did not set up the Task Manager correctly. It sounds like your Task Manager settings are killing ThrottleStop. Try following this guide.

Effective clock speed

Hi, I have a problem with my CPU (8700K), which is that my effective core clock speeds decrease after a while. I have an all core OC set to 4.7GHz and initially when starting the PC, the effective core clocks are 4.7GHz as well when CPU is under load. These are later (like 10 mins later after...

Now everything is working exept mhz is to high in battery mode, starting with 798 mhz is getting up to 2700 mhz. how to keep in lowest number? sorry for too many questions .
