overclocking limited laptop board

[Hoorow]

i did my setting mostly searching from unclewepp or from forums but i still wonder if i can push it more. i use hp 14-al107nt which locked board with i5-7200u and 940mx board. i upgraded power brick from 65w to 90w for just in case,

i will run prime95 and game with log file and attach it here

31 is the max multiplier for your CPU. Your computer is already running at its maximum speed.

No need to check Clock Mod or BD PROCHOT or Task Bar or SpeedStep or More Data. They do not make your computer run faster.

oh thats sucks i guess then there is no way to prevent red POWER because of,

so i cant prevent this. if use ts bench it goes perfectly for seconds then it drops watt and clock speed and makes red POWER

 

[unclewebb]

prevent red POWER

The TPL window shows that the MSR power limits and the PP0 Power Limits are both locked. Did you lock these or did the BIOS lock these?

The PP0 Power Limit is rarely used. I do not recommend checking or setting anything PP0 related. There is no need to lock the PP0 power limit.

The MSR turbo time limit is set to the max. If the BIOS did this then there is nothing you can do. I have never seen a BIOS do this so I am guessing that you did this. Try unlocking this setting and reboot. Increase the PL1 and PL2 turbo power limit values if you have power limit throttling issues. Set the time limit back to the default 28 seconds. Requesting 3.67 million seconds is usually ignored by the CPU.

 

[Hoorow]

yes sir i locked these thinking cpu will only use this values and wont change it

i will reboot it after posting this. also power balance for igpu wont improve cpu performance right? i only use external gpu

 

[Hoorow]

i guess i have to lower power limits or something or else it will continue giving me red power. attached log file, used prime95 for test and test option was small ffts(L1/L2/L3 Caches) i will use hwinfo sensors to see which one triggers this

 

[unclewebb]

The log file shows PL1 power limit throttling right at 15W. The 7th Gen U series processors have a 15W TDP power rating. Some manufacturers like HP will program an embedded controller EC to enforce this 15W power limit. The EC power limit is separate from the MSR and MMIO power limits so you cannot use ThrottleStop to go beyond 15W during a long term stress test like Prime 95.

i will use hwinfo sensors

There is no need to do that. The ThrottleStop log file shows PL1 power limit throttling at 15W. Your screenshot shows that the MSR PL1 power limit is set to 30W and the MMIO power limits are locked. Those two power limits are not causing the throttling problem. That means it has to be the EC PL1 power limit that is set internally to 15W.

 

[Hoorow]

okay thats good to know so i can either set PL1 to 14-15 or modify bios file to increase EC power limit right?

 

[unclewebb]

I have not heard of anyone modifying the bios file to increase the EC power limit. Some users modify the IMON Slope value in the bios to get around these power limit throttling issues. Setting IMON Slope to 50 tells the CPU to report 50% as much power consumption compared to actual power consumption. If the computer is consuming 30W, it will only report half as much, 15W, so it will be less likely to trigger any power limit throttling.

I am not sure if this is possible to do with your HP computer. I think recent HP laptops are well locked down. For 7th Gen, maybe the IMON Slope trick is still possible.

yeah you are right i remembered it as bios flashing i will search that even if it will take times. thanks unclewebb, i have question again does setting to too high or changing it can it damage board? im using ducted cooler that blows into air intake, i dont have much temp problem except minus 8 thermal pad being too bad.

 

[unclewebb]

does setting to too high or changing it can it damage board?

Buy me 100 similar laptops and give me a few years to do some testing and I will let you know. I might get bored first.

You have a 9 year old laptop that has already lived a long life. It could crap out tomorrow for any reason whether you play around with the power limits or not. You should avoid changing anything if you are worried that doing so might kill your laptop.

 

[Hoorow]

yeah you are right sir, i will try to do it and if i can i will post it thanks for everything unclewebb

 

[Hoorow]

YESS i did it. since i added 25W to stock charger so i didnt go full mode only half which is extra 15w total 30w. with full cooling and L1/L2/L3 Cache test i say maks 92 temp(which terrible but i will buy ptm7950 currently using minus8 pad) and maks wattage is 12.3W x2 24.6 withouth loosing turbo mod thank you for recommending slope mod

 

[Hoorow]

hi unclewebb last questionis there way to lower laptops VR VCC temps? without external cooler like changing component(probably not preferred ) could small heatsinks work? i installed ptm7950 im temps are really good except VR VCC and it disables turbo to cool itself down. CPU is around 70C but VR 95C

 

[unclewebb]

I do not know how to make poorly cooled voltage regulators run cooler. Many laptops with low power U series CPUs have poor airflow and barely adequate cooling. Adding some small heatsinks is about the only option unless you want to hack up your laptop case with a Dremel tool to get some air in there.

 

[Hoorow]

ig i will use that if i can fit it withouth cutting back panel else maybe adding little branch to cooling tube so it can cool vr
