Re: what should we try out first: replacing the mobo or the RAM, or reinstalling Windows
these new crucial ram guaranteed to work for 8920 according to vendor.
try remove all new ram and install old ram. If system is rock stable, one or more of new ram is incompatible. Remove all ram, install only one new ram in DIMM1, test for stability. Chances are 1/4 new ram may be corrupted. By testing individually you isolate the bad apple. It doesn’t sound like you need to replace mobo or reinstall OS at this point.
Memtest is a good idea. Your PC might also have a built-in (streamlined) RAM test similar to memtest if you hit F12 on boot, and look for the ePSA hardware test option.
But yeah, I would definitely test/troubleshoot the RAM new and old, before reinstalling the OS or replacing the mobo, especially since this issue came up right after you installed new RAM.
Thank you all for your replies. Sorry for the late update but testing all 4 RAMs took some time.
Turns out that all the 4 new RAMs behaves totally stable when used singly. However as soon as I put 2 of them in slot 1 & 3, errors show up in Memtest.
Just to make sure it's not some of the slots that are faulty I tried putting only one RAM in slot 3, no error at all.
Anyone had the same experience before? What log / info should I provide here? What can we do to investigate further?
@Vic384 I see your point. The reason I bought the 3200 version is because it's somehow cheaper than the other ones like 2666 version here in Japan. If in someway down tuning the RAM would solve the problem I would love to try out first.
For further update, I just tried out the other pair of the new RAMs and it's a bluescreen again.
In short, my 4 new Crucial 16GB RAMs can all run singly, but they give my random bluescreen when going in dual channel. All 4 RAMs have been tested singly with no issue. The 2 old 8GB RAMs that came with the XPS 8920 machine make no trouble however.

There isn't support for that here.
Rootkits are un detectable. There isn’t a simple, updated virus definition file or all-encompassing antivirus tool to guard against fileless malware attacks.
Fileless malware can remain undetected because it’s memory-based, not file-based. The SPD rom is a rom it doesnt lose data from power loss or removal. The key is that fileless malware isn’t written to disk like traditional malware. Rather, fileless malware is written directly to ROM/RAM/UEFI partition memory — which is not accessable by user and doesn’t leave behind those traditional traces of its existence.
KERNEL_SECURITY_CHECK_FAILURE (139) A kernel component has corrupted a critical data structure. The corruption could potentially allow a malicious user to gain control of this machine.

@lambchie You could try running Memtest86. Memtest86 boots from a USB flash drive and operates independently of the operating system.

@lambchie I don't think there is much more to investigate. I think you need to contact Crucial and tell them your problem. Perhaps you should have purchased this RAM: https://www.crucial.com/memory/ddr4/ct2k16g4dfra266/ct18793863
I don't think you could not use the extra speed of the RAM you purchased in the XPS 8920.

The SPD chip on the ram can have malware
You arent using windows 10 20H2

If there is malware, the malware runs independently of Windows because Memtest 86 does not require Windows to run and the RAM is failing Memtest86.

REPAIR UPGRADE to 20H2 might fix except in the case of non file malware hiding in Rootkit or ROM or SPD or UEFI partition.
