    IRQL_NOT_LESS_OR_EQUAL and Kernal Security Error after RAM upgrade


    I have a Dell Inspiron 7577 Windows 10 20H2 Build 19042.928 with a single stick of 16GB RAM stock. I recently purchased a 16GBx2 RAM Kit from Crucial (CT2K16G4SFD832A) which per their compatibility tool should be compatible. I attempted to install the new RAM, both sticks individually would BSOD after POST and fail to boot into Windows. Thinking that the RAM was defective I went through the RMA process and received a replacement RAM kit. However, I run into the same error, with a single stick installed, I get a BSOD prior to the account login screen with a IRQL_NOT_LESS_OR_EQUAL error and with both sticks installed I get a KERNEL_SECURITY_CHECK_FAILURE again prior to the account login screen. As soon as I reinstall the stock RAM stick I can boot into Windows without difficulty and everything functions normally. Prior to installing the new RAM fast startup was disabled and bitlocker encryption was suspended. I can't boot into Windows with the new RAM kit so the logs were collected with the stock RAM stick.

    Have you changed clocks, voltages or RAM timings in the BIOS? Do you use XMP profiles?

    No custom voltages, clocks or timings, and no XMP profiles. Those aren't supported in my BIOS which is the most up to date version, 1.12.1.

    Perhaps the RAM is incompatible with your computer? Have you checked any other RAM model compatible with your computer?

    I've considered that there may me compatibility issues with the RAM, Crucial guarantees compatibility based on their tool, but the alternative is that they sent me four consecutive dead sticks of RAM. Even under heavy load my laptop is stable without issues with the stock RAM in place.
    I have not trialed other sticks of RAM. The only thing is that stock I have DDR4-2400T but the new RAM is DDR4-3200 but that should automatically downclock itself.
