Maintaining consistent FPS after upgrading to a 115W RTX 2070 on mobile devices
Maintaining consistent FPS after upgrading to a 115W RTX 2070 on mobile devices
Hi everyone,
I own an ASUS ROG GL704GW with an i7 8750H/115W RTX 2070 and 16GB DDR4 at 2666MHz.
I’m aware that laptops aren’t built for overclocking, but I still wanted to give it a shot.
I tried the MSI Afterburner app for overclocking this GPU, but the issue began when I realized my FPS stayed the same regardless of GPU core speed in PUBG.
My FPS consistently ranged between 160-170 on textures and AA ULTRA, while core speeds were around 1650MHz most of the time.
After lowering it to about 1350MHz, I still got the same FPS (160-170), and once I maxed it out to 1995MHz on the core, the performance remained unchanged.
The GPU temperature never exceeded 82°C—throttling was starting at 87°C for the GPU and 95°C for the CPU under full load, so there’s no thermal or power limiting in this setup.
I’m really puzzled by this and would appreciate any advice or help from someone more experienced.

Overclocking laptops doesn't really bring about a significant improvement, I've tried it and wouldn't suggest it. You're shortening your laptop's lifespan for just a few frames of extra speed, the GPU can handle more power but it will also generate more heat, possibly exceeding its limits and reducing its longevity. I've dealt with burnt-out ASUS ROG GPUs and Mobos; their cooling systems couldn't keep up because laptops have very strict temperature controls (unless they support overclocking). This isn't the solution—just sharing my past experiences. If you're planning to keep trying, monitor your heat levels and change the thermal paste regularly. Have a good one!

You're reducing your laptop's lifespan for just a small 2-5 fps boost; the GPU is already handling everything, adding more power will only increase performance by 1-10% but also generate more heat, possibly exceeding its limits and shortening its life.

When fps doesn't change between ultra and the lowest settings, that usually indicates a cpu limitation...
Also, as davissima pointed out, it's not worth overclocking in laptops. Especially so with Nvidia's 10, 16, and 20 series gpus, as they are TEMPERATURE SENSITIVE; gpu boost clock is affected by temps.
If the thermal headroom is already poor, overclocking does nothing for those gpus.
PUBG is also a poorly optimized game. There's likely no further performance to be had when the game engine doesn't know what to do with all that's available to it.
Thank you for your assistance. I will definitely stop overclocking it after receiving these details. I understand that laptops aren't built for this, but I reworked the piece once a week after using the thermal grizzly Kyronaut and achieved really good temperatures during full load. (Competition laptops like Acer, MSI, or Razer with the same CPU reach up to 100-103°C under load, while mine stays around 90°C.) So I thought I had a suitable environment for overclocking the GPU because the temps are around 80 and my laptop can handle up to 87-90°C for the GPU. But thank you again for the advice.
One more question... Do you think the i7 8750H is too weak for this GPU, which is why I don’t see any performance improvements?
Thank you for your question. I’m still trying to understand why the temperatures remain consistent across different GPU settings—whether playing for short or long durations. It’s unusual for the GPU to stay in the same range, like 80-81°C regardless of workload. (CPU temps reaching up to 90°C seems quite odd.)
Some people think 90°C is not enough for that CPU... 85-90°C are perfectly normal, just compare with other laptops from brands like Razer, MSI, Lenovo, etc. They all reach temperatures up to 98-105°C when fully loaded (like gaming). My own temperature stays around 90°C during heavy use if I consider my room is usually between 25-27°C. In my country it’s very cold, so heating the room a lot is necessary... When I first bought the laptop I faced similar issues with thermal throttling – CPU would spike to 100-105°C without any issues. Clock speeds dropped from 3.9 GHz to 3.4 GHz easily because of overheating. Things I tried didn’t help much: cleaning dust, repasting with MX4, repasting with liquid metal – the last one really helped (reduced temperature by 15-20°C). After two months, I had to remove the laptop completely. Metal started leaking onto the motherboard contacts, which I noticed when I cleaned everything inside.
