Note, the supplied Service Tag shows an Area-51 R6 Threadripper. So are you speaking to that Area-51 R6 Threadripper or to a different non-Threadripper Area-51 R4?
It’s May 2023 and I have the exact same computer the Alienware Threadripper edition R6 bought about 3 years ago. Worked fine no issues then about 3 weeks ago got msg from support assist scan showed memory was failing a test. Have 4x 16 gb DDR4 DIMMs. Ran bios 5 hr deep scan. Report stated memory issue resolved. but back in windows support assist scan still shows memory failing tests. Dell had sent one 16g DIMM to replace whichever of the old ram was faulty. However once I opened the case and removed two of the old memory and tried to run pc to see if they were good modules the pc no longer boots no matter what combination of old and new memory I use. With the new dimm in slot 1 I get 4 beeps repeatedly. On site tech could not resolve the issue. So.he recommended a new motherboard but the processor could not be hand unscrewed from the. Old motherboard so now awaiting a new processor. I’m concerned the inability to boot up willl persist with the new system board since only 1 new DIMM is available and someone else is having the same issue.
it turns out this is a known issue called “ No POST Issue” meaning: No Power On Self Test. Browse to FAQs for Alienware desktops. Find topic “PC will not start” Read instruction for resolving No POST issue.
2 methods are described first restart with minimum hardware and remove all peripherals except keyboard and mouse. If it boots properly add other hardware one by one to identify the faulty hardware.
if that fails second approach is to do a hard reset. BIOS maybe corrupted. Power off, disconnect AC cord and hold the power button for 15-20sec to drain residual power. Reconnect AC, power on tapping F2 key repeatedly to enter bios and reset the real time clock. Detailed video and instructions in the FAQ as mentioned earlier. My PC currently is disabled with no processor awaiting new processor. I will report if this fixes my issue. Hope it helps anyone with similar issues.

You could try loading the bios defaults. It's possible some memory settings were inadvertently changed.

Sorry the title is misleading it beeps 4 times, cannot access BIOS setup. I did try the CMOS reset jumper.

"then put each one in slot 1 one at a time,"
Maybe it is a motherboard hardware issue with slot 1. Try putting a stick in slot 2; different channel.
You can also try a CMOS reset using the CR2032 battery removal method before installing in channel B; more efficient than the jumper method.

The video card has RAM too, did you rule out the GPU?
