ASUS GU502GV - constant Current/EDP Limit Throttling / low FPS in VR

[ATLANTICA_NFS]

Now you know what setting controls those EDP alarms. Most desktop boards set the current limit sky high so it does not interfere with CPU performance, ever. If setting the current limit to 160 is going to give you some sleepless nights then leave it at the default setting.

Just curious about the C states. When your computer is idle, open up the C States window in ThrottleStop. Does it show your CPU using the core C7 state or any of the package C states? On locked CPUs like the 9750H, the core C states need to be enabled so the CPU can achieve maximum performance. They also reduce power consumption and help the CPU run cooler. Many manufacturers have decided to limit the package C states. The core C states should always be available.

Thanks for the feedback!
See screenshot attached regarding C-States:

Your CPU is using Core C7 like it should be. It looks like the Package is being limited to C3. That is not ideal for power consumption but is pretty typical. Your CPU supports package C8 but it seems that many manufacturers turn this power saving feature off deliberately or it gets limited to package C2 or package C3 accidentally by a poorly programmed driver. Core C7 is the important one.



When a CPU is idle, cores can spend up to 99% of their time in the C7 state. If your screenshot was when your computer was idle, have a look for any programs running in the background that do not need to be running all of the time. Getting rid of background fluff is an easy way to improve performance.

In ThrottleStop, try raising the PP0 Current Limit as well as the IccMax current limits. Raise all of these sky high and see if it makes a difference. I would also suggest uninstalling Intel XTU.

Throttlestop works great on these machines IF you enable the undervolting in the BIOS and set it to -80. Throttlestops lets all 6 cores boost to 4ghz forever!

Another thing to check, don't use any USB C /Thunderbolt connections that supply power to your laptop. For some reason, your laptop will ignore the 230w brick and use the 65w USB C port instead. When on USB c power, once the CPU hits a certain temperature, the BIOS uses dynamic current limiting (if that's what it's called) to throttle the CPU.

Unplugging the 230w brick from the laptop is not enough to force the laptop over, you need to unplug it from the wall to reset it. Idk why.
