Question RAM has down clocked from 3466MHz to 2400MT/s ?

[Iman Infinite]

Hello, Kind Community!
I have an Alienware Aurora Ryzen Edition R14 with 16GB of Asgard DDR4 3600MHz 8x2 RAM sticks. At first, it was running at 3466MHz, but then after updating BIOS and Windows 10 to 11... and in BIOS settings > Performance tab > Overclocking tab was locked/greyed out... I proceed to click on Optimized Defaults and rebooted my PC. After this, overclocking tab got enabled, but RAM has actually down clocked to 2400MT/s.

I tried out Alienware Command Center to look up for some tweaks and profiles if there is any XMP profile option is available, but sadly found nothing.

I tried to proceed with overclocking tab located in BIOS with manual customization and selected 3000Mhz to 3600MHz settings step by step with correct 1.35v Plus 18, 22, 22, 42, 64 but when I applied these... the system rebooted 3 times and said:

"Make sure you have qualified XMP supported memory"

But I have 3600MHz sticks installed with XMP supported, and it's not even achieving its base speed, why do I further overclock it..

Then, tried to put some relaxed timings for 3600MHz 20, 24, 24, 44 with 1.37v..... but same again, it reverted to 2400MT/s after rebooting 3 times.
CPU-Z does show it's running on JEDEC profile and not on XMP.

So, what do I do? How can I get that base speed back?

which BIOS version is installed now?
reset the buos by cmos jumper on the motherboard itself and try enabling xmp afterwards again

Welcome to the forums, newcomer!

Since you've stated that you'd updated the BIOS, I would try and see if you can clear the CMOS and that alleviates the issue. Ideally you're advised to disconnect from the wall and display, then remove the CMOS battery, press and hold down the power button for 30secs to drain any residual power, then reseat the battery after 30mins.

Have you checked to see if there are any further BIOS updates pending for your prebuilt? Speaking of Windows 10 to 11, did you perform the upgrade through the internal update system? If so, you're advised to reinstall the OS(Windows 11) after recreating your bootable USB installer for Windows 11.

BIOS version is 2.21.0 (The latest one available, I updated through BIOS Flash Update).
Does Alienware have any reset button on their mobos? (I did not see any) or I need to remove the cell/battery and place it again?

Thanks for the warm welcome.
Is there no any way to fix it without removing cell/battery? And how can I clear CMOS (is there any settings in the BIOS for clearing CMOS)

After updating, I have checked the updates by scanning through Dell Support Assist, and it said "you are up-to-date"
Before updating the BIOS, I downloaded the update file from Dell's website, and it detected my system and showed up recommended files to download and install. (where support assist couldn't be able to install BIOS update.... stuck for hours... so, I ended up updating it through a Flash Drive).

Also, in Alienware Command Center, there is no Fusion Tab. (I have seen that Fusion tab is related to tweak CPU and RAM profile) but IDK why it's not showing up there whereas it is installed properly.
Checked out the destination of Dell Installed services in Program Files > Dell > Fusion.

I watched some videos on YouTube - - - a guy with an Alienware laptop with the BIOS version 2.20 including XMP option in the performance tab where mine one is 2.21 and doesn't have any XMP option.

you might need to ask Dell, eventually a bug in the update file
resetting bios by removing the cmos battery might be the only chance you have

OK then, I should give it a try and will let you know soon if this can fix the issue. : )

Please show screenshots from CPU-Z - memory and spd sections.
