Hello, tell me, did I do everything right?
Is it normal that the processor consumes only 60W during gaming?

Temperatures are all normal, I completely re-pasted the entire laptop
GPU + CPU - Thermalright Heilos 2x40x40mm
VRAM - Thermalright Valor Odin 1.5x90x50mm (1 piece)
VRM - Liquid thermal pad FrostMining 10 grams (2 jars). To replace FrostMining, you can take UPSIREN U6 Pro or UX or Fehonda LTP81

You lowered all of the turbo ratios to 47 so it makes sense that the CPU is consuming less power.

Turn on the ThrottleStop Log File option and attach a log file. As long as the CPU is running at the speed that you are asking it to run at then everything is OK.

Too bad Razer did not include a more robust heatsink and fan. When the CPU is reaching 93°C at only 90W, that does not give you much headroom to play with. The cooling needs to be capable of dissipating twice as much heat to get full speed and maximum performance out of a 14900HX.

Your missing logo makes ThrottleStop look a little naked. Here is a Razer logo to help the cause. Right click on the image and save the Logo.png file into your ThrottleStop folder.

Thanks for the logo, that's exactly what I wanted to do, but my options didn't fit in proportion.

"Log" with these settings.

Looks like your laptop has a feature that limits the CPU to only 60W when the Nvidia GPU is active. ThrottleStop cannot be used to fix this limitation. I do not know if any Razer software will allow you to adjust or disable this feature. Probably not.

TVB throttling can be fixed by clearing the Thermal Velocity Boost box in the FIVR window. In your situation, you might as well leave this checked. You do not have enough cooling to run your 14900HX at full speed.

Most likely this is done by synapse, if you enable CPU OC, there will be no PL1 limit

low fps "Rust" game?

gave 90-110 fps for the first 5-10 minutes after entering the server in the game Rust, after that the fps begins to gradually drop, sometimes drops to 40 fps.

- Temperature CPU: 80-96 ℃ | GPU: 65-70 ℃
- Undervolt: CPU: -70 P: -60 E: -60

I also have a Viper v3 PRO mouse, if I select a polling rate of 8000 Hz, then when turning the camera, the FPS drops to 30. If you set the polling rate to 1000 Hz, then there are no problems.

I also noticed that the system works worse with synapse 4, so I went back to synapse 3

P.S. I understand that Rust, namely Unity, is not optimized, but on my previous desktop PC (RTX 3080 and i9 12900k) it gave stable 120-130 FPS in the same screen resolution of 2560x1440 and the same settings.

Check the Log File box on the main screen of ThrottleStop. Attach a log file from a gaming session.

The GPU MHz is way down compared to the GPU-Z screenshot in your first post. Is the GPU being power limited or maybe the GPU MHz is throttling.

You said before that CPU Overclock needs to be enabled to get more performance out of your CPU. That is not checked in your most recent screenshot. Maybe that has something to do with your FPS drops.

Figured it out, for some reason the GPU frequency (RTX 4090) drops on this server, on other servers everything is fine with the frequency and FPS, maybe some plugin.

New question: why does the yellow inscription "EDP OTHER" appear on the GPU? Is this the integrated Intel graphics sensor? And how critical is this?

Hi! I am new to the forum and I recently bought a lenovo legion 5 pro with 14900hx/4070. I would really appreciate some guidance with the undervolting process through Throttlestop because I tried it with no prior experience but it was either not working or the results were worse than stock. Should I start a new post here or...?

Search this sub forum with those words : lenovo legion 5 14900hx. You’ll find plenty of tips to under volt. I own a lenovo legion 5 pro with 13700Hx. This thread helped me:
