Hi everyone. I have an MSI raider GE78HX 13VI. I'm trying to overclock my gpu with Afterburner. I set the core clock to 2500 and the memory clock to 2500. When I run a benchmark say Time spy the memory clock is stable but the core clock drops to 2150-2275. What am I doing wrong? I see other results on Futuremark with the same specs I have and mostly MSI Raiders, their scores are way over what I get and their core and memory clocks are even a little higher than mine. Any help would be greatly appreciated. Thank you.

you will need to play with the curve and undervolt not only OC
Come join the Lenovo Legion Discord as a lot of people are getting great scores over there Join the Legion Series Discord Server!

You've hit the power limit. Definitely look into what others are doing with undervolting your model. How are your temps under full GPU load?
Thats because you're applying an overall overclock to the entire voltage curve.
You need to individually raise one of the points along the voltage curve so that you're also undervolting, therefore not hitting power limits that fast.
Reset everything and raise only the 900mv point to ~2600-2800Mhz, apply and test. if it works, try for more.
With laptop GPU overclocking its all about finding the sweet spot of how much mhz you can gain with the lowest possible voltage, so that you hit the power limit as late as possible.

You're GPU is individually capped at 175W and your CPU/GPU load also has a cap. Given the Intel chips can peak well over 100W, you need to look into limiting your CPU wattage and balancing that with your GPU wattage if you want the most out of your laptop.
The issue with limiting the CPU watts is you can start dropping clock speed and performance; Intel CPUs scale pretty linearly with wattage.
I have a 13900HX and if I limit my CPU wattage to 80-100W, the GPU tends to boost higher and longer. To keep my clocks from dropping, I disabled 8 e-cores and 2 p-cores in the bios, assuming your bios supports it, I'd experiment with how many cores you can turn off without losing performance.

In old days you could pair two 300w power supplies , mod bios and push gpu to the limit. They ruined everything now
