Power Limit Throttling on i5-8265U

Hey, I'm looking for help on power limit throttling on my HP Pavilion cs1063cl with a Whiskey Lake i5-8265U.
I undervolted my CPU with an undervolt of -100mV, which is perfectly stable, and reduced temps quite a bit.
I noticed that under full load, such as Cinebench R20 render, the CPU draws around 45W @ 3.62 GHz, hits the Tjunction and falls to around 15W @ 2.52 Ghz, at 72 degrees. Is there any way that I can increase the frequency under load to around 3 Ghz? There is some thermal headroom, so I'm wondering if I can increase my Cinebench R20 results. Currently, it's at 1168, which is quite low for this chip.

Thanks!

Most HP laptops with low power U series CPUs are locked down to 15W. You can try setting the long term turbo power limit in the TPL window higher than 15 to see if it makes any difference. You should also try using the FIVR Disable and Lock Turbo Power Limits feature. You need to first download, unzip and install the RwDrv.sys driver into your ThrottleStop folder.


If you have tried both of these things and you are still limited to 15W then you are out of luck. Some OEMs leave these power limits unlocked and some lock things down so there is no way around this. Open up Limit Reasons. Does it show a thermal problem or a PL1 or PL2 power limit that is causing the throttling?

I downloaded the file on Mega, unzipped it, added it to the ThrottleStop folder, used the FIVR Disable and Lock Turbo Power Limits, and tried to increase the Power Limit to 20W. For some reason, it still falls down to 15W. The temperatures under load are reasonable at around 74 degrees, and the Power Limit 1 is highlighted in the ThrottleStop in Limit Reasons.
There is something called Power Limit 3 which is locked, though. Could that be the problem?

Here are my settings for ThrottleStop.

PL1 is the long term turbo power limit. That is the reason for throttling. Many HP laptops lock the Intel CPUs down so long term, they do not exceed the TDP which is 15W. When a company does this, your power limit settings in ThrottleStop will be overridden.

Power Limit 3 is not being used. No need for it. PL1 is killing performance enough already.

I think HP should be shot at dawn I have this CPU on a 1030 G4 at £1600 I never expected to get the performance of a £300 laptop in return.
I have several early NUCs that easily match this CPU my daily NUC is the 8259u that's 60% faster than this yet should only be 12% slower!
The weird bit is the previous model G2 had a 7200u that had no such throttling and was just under this crap from 2017 line, forget about installing a new windows 10 it does not work forget about mac or Linux both don't work either, to even get it to run on ultimate power you have to in effect hack it and to get it to run the cpu at 100% another hack and if you tell windows not to throttle in policies that fails to work as well proves we are all being short changed and financially disadvantaged. So either a faulty design or by TOTAL DESIGN in which case is a consumer scandal because there's no mention of it anywhere on the HP sales sites anywhere in the world.
