Many different BSODs after RAM upgrade

Hi,
I have a GL 702ZC laptop which comes with 16 GB of DDR4 2400mhz Samsung PC4-19200. I decided to install another 16 GB of RAM: the Ballistix Sport LT DDR4-2666 PC4-21300 listed as compatible with the notebook as You can see here: RAM SSD Upgrades | ASUS ROG Strix GL702ZC | Crucial EU.
After installing the new RAM, i updated the BIOS to the last version and began to test the 32 GB of RAM to be sure that everything was fine.
I did: 16 sessions of HCI-memtest, 32 GB of RAM tested, 400% pass on each session got 0 errors on all the sessions, Windows 10 memory test, got 0 errors, 4 pass on memtest86 got 0 errors, 2 h of Prime95 both blend and small FFT, got 0 problems, Cinbench R15 multiple runs and 0 problems, Heaven and Superposition benchmarks (multiple runs) and got 0 problems. So I was happy with the new RAM. Until 7 days ago, when my laptop began to crash after few minutes in Windows and sometimes at the log in page (so sometimes I can't even log in). After few crashes, the system suddenly stop to have problems and let me work in peace even when I use CAD or FEM softwares with intense workloads. The crashes only occurs on cold boot (the laptop has been off for a night for example).

The BSODs I got are:
APC_INDEX_MISMATCH
SYSTEM_SERVICE_EXCEPTION
KMODE_EXCEPTION_NOT_HANDLED
PAGE_FAULT_IN_NONPAGED_AREA (fastfat.SYS)
PAGE_FAULT_IN_NONPAGED_AREA (Ntfs.sys)
PAGE_FAULT_IN_NONPAGED_AREA
SYSTEM_SERVICE_EXCEPTION (aswbidsdriver.sys)
SYSTEM_SERVICE_EXCEPTION (win32kfull.sys)
MEMORY_MANAGEMENT
PAGE_FAULT_IN_NONPAGED_AREA (atikmdag.sys)

Until now I have tried:
the error check (right click on the C unit->Properties->Instruments) and got 0 errors
the sfc /scannow command in the Command Prompt (run as Admin) and got 0 errors.
Uninstalled the external antivirus, and uninstalled the AMD software with the amdcleanuputility and reinstalled the drivers.

But I still get these BSODs.

Please help.

Thanks.

Please read BSOD Posting Instructions & How to upload files

The Beta version has been developed to ultimately replace the DM Log Collector for different reasons, including that it didn't always, for unknown reasons, created all files it was supposed to. Please download the Beta version and run it a next time if another BSOD occurs.

Could you remove the RAM module that was already present and seat the new module in the slot the old module uses, I would like to ensure the added memory doesn't cause issues by checking the compatibility, used slot and such manually. Manually, because in the end the best test with memory is to do it physically yourself.

Please remove the samsung module.
