Is it fine to reduce/cap your GPU clock speed?

I have a Nitro V15-51-541P with an RTX 4050 GPU.

I got this laptop for just a month ago, and it is pestering me with blackouts while I am gaming. I already brought this to acer customer service, and what they did was thermal repasting and burn in for 2 days. Unfortunately, the blackouts still occur at a lesser frequency.

It got me to the point to ran tests myself to figure out what the problem was. I used MSI Afterburner to observe the performance of my laptop while playing. Notably, my GPU ran a constant 2.58GHz while using 40-50W power.

Then, I ran Furmark to test my GPU with 4K/UHD preset in 1980×1080 resolution. The results were as of follows:
1. Stable below 60°C (34°C min; 59°C max) of Temperature

2. Stable 70W draw of power

3. Stable 1.8GHz of clock speed

4. Stable 140 FPS

Also, my friend with an RTX GPU 3050 (6GB VRAM) runs at around 2GHz of clock speed while drawing around 60W of power.

So, before playing, I tried capping my GPU clock speed at around 2GHz using MSI Afterburner. Viola! I played for almost 4 hours non-stop without any blackout!

I am not sure if it resolves my problem. Nonetheless, I want to know if it is safe to do? Also, if it does resolve my problem, how and why? I am really not sure about the explanation, but I do hope to know someday.

Also, I do know that my RTX 4050 Laptop GPU should be able to run more than 2.3GHz without blackouts. However, I will try to run some tests if it works fine as it should be…

If you know a similar case, let me know!

Hi John_Rafael04

– Your Nitro V15 with RTX 4050 may be experiencing blackouts due to aggressive boost behavior—not just from the GPU, but also from the CPU. If MSI Afterburner helped stabilize the GPU, it’s worth optimizing the power settings system-wide.

– Try this sequence:

– Switch to the Balanced power plan in Control Panel > Power Options.– Then go to Settings > System > Power & Battery and select Best Power Efficiency under performance mode.– If blackouts or BSODs persist, open Control Panel > Power Options > Change plan settings > Advanced power settings.– Expand Processor power management > Processor performance boost mode and set it to Disabled.

– If you don’t see the “Processor performance boost mode” option, you’ll need to unhide it via the Registry:

– Press Win+R, type regedit, and navigate to:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7– Double-click Attributes and change the value from 1 to 2.– Restart your system, then check the Advanced Power Settings again.
