Disable iGfx and 2080 on Alienware Area-51 R1?

[2CPU]

I've seen some really great scores from Reddit with the amplifier. I went to check the how-to and post was removed by a filter. Does anyone know the steps? Guessing I hook up the display to the back of my card in the alienware amplifier.

What are trying to accomplish by disabling 2080? It wont increase any fps anyways when you use external GPU. 

 

Infact I would recommend Lossless Scale to utilize both external GPU and the internal GPU

There is a reddit poster that has high 3d mark scores and seems to point to disabling the 2080 from the PCIe with RU.efi also changing speeds of the RAM to 2933mhz

These posts are mine. Unfortunately, Dell reported my posts to protect its own performance interests and profits, so users wouldn’t find out about the capabilities of this masterpiece and upgrade their devices.

با غیرفعال کردن 2080 چه کاری می‌خواهید انجام دهید؟ به هر حال وقتی از پردازنده گرافیکی خارجی استفاده می‌کنید، هیچ فریم بر ثانیه‌ای افزایش نمی‌یابد. 

 

در واقع، من Lossless Scale را برای استفاده از هر دو پردازنده گرافیکی خارجی و داخلی توصیه می‌کنم.

The monitor is now connected directly via DisplayPort to the RTX 3080 Ti.

 

What has actually improved (real benefits):

 

✅ Improved performance and smoother FPS

 

• Every frame is now rendered and displayed directly by the RTX 3080 Ti.
• No iGPU path, no frame copying, no Optimus interference.
• Games feel significantly smoother and more responsive, even if raw FPS hasn’t dramatically increased.
• Stable frame rates and frame times in heavy games.

 

 

✅ Lower CPU and GPU temperatures

 

• With both the iGPU and RTX 2080 disabled, the laptop cooling system no longer needs to handle 2–3 GPUs.
• Internal heat buildup is reduced.
• CPU package temperatures drop by 5–8°C in some scenarios.
• Fans spin less and the system is overall quieter.

 

 

✅ Power efficiency and thermal ceiling

 

• Less power wasted on unused chips = lower CPU and eGPU temps.
• Cleaner power delivery and reduced system bottlenecks.
• Battery lasts longer during idle or light use.

 

 

✅ Driver stability

 

• No more switching between GPUs, unexpected crashes, or application confusion.
• Device Manager shows only the GPU you’re actually using.
• Fewer background services (no Intel GPU services, no unnecessary switching).

 

 

✅ Cleaner boot, no glitches

 

• Faster and smoother boot process.
• No screen flicker, no black-to-white color shift during GPU switching.
• Display output comes solely from the RTX 3080 Ti — exactly as it should.

 

 

Benchmarks and games

 

• 3DMark Fire Strike and Time Spy show more stable and higher CPU+GPU scores.
• Real-world games like STALKER 2, Cyberpunk 2077, and The Witcher 3 run extremely smoothly without any quality loss.
• GPU-Z confirms full GPU load, proper bus usage, and no bottleneck from the iGPU.
