I think… No it can’t support rtx 3080 as you can see the gpu photo you have 3 vram areas not two areas if you use rtx 3060 may be can use this heatsink
Find above 4G decoding in bios and make it enabled then the resizable bar will shown then make it enabled but it works only with rtx 30xx gpu

Special thanks to devolper79, who gave new hope to the P870 laptop with a modified heatsink to support all GTX 10xx - RTX 30xx graphics cards. Thank you very much, and soon when the heatsink arrives, I will do a full review with the RTX 3080.
2 Beeps on Dell Studio 540 indicates Memory or Memory slot failure. I would suggest you to remove and reseat the memory on the system to check if the beep codes disappear. If two or more memory modules are installed, remove the modules, then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.
I don’t know how you can use the spi programming tool cuz i don’t know where is exactly location the EC and BIOS chipset cuz the blind flashing can fix many issues like that
Download the original Alienware unmodded A03 bios from Dellat Drivers and Downloads | Dell [united States] The file is named "M18R2A03WIN"
Extract the contents of M18R2A03WIN to a new folder named "Alienware recovery" anywhere on your useable computer. In there you should have a bunch of files. (9 in total)
Look for the one called QBR10EC.fd
Rename this file to M18R2.hdr
Place the file M18R2.hdr on a formatted fat32 usb stick on its own.
Thats it. Blind created
Recovery process:
To do the recovery process you need to remove your m18x r2 battery.
Unplug the back power cord as well
Plug the usb stick with the file M18R2.hdr in the M18X's e-sata port
Now hold down the END key (located above the numbers key pad) at the same time while your holding the END key plug in the power cord only, you will hear the fans turn on full bolt.
Release the end key and wait
After a few seconds once the file is read from the USB stick you will hear 20 or 30 beeps (sounds like a garbage truck reversing)
After the beeps stop the m18x will shut down and reboot itself. ( 1 or 2 times depending)
Once reboot all will be back to normal A03 bios.
Connect the battery back if you wish after successful boot.. That's all folks, things should work now unless you bricked the EC controller, which is hard to do.
