[Solved] IRQL Driver Not Less Or Equal Issue: Windows 7, Ryzen 5 1600, MSI B350, Crucial DDR4 RAM, GTS450

Hello.
About three weeks ago, I replaced components on my computer. Since then, I have seen the blue screen four times with the message IRQL Driver Not Less Or Eqaul. Then the computer restarts and works normally. It happened on various occasions: starting the game, browsing the internet, watching a movie. Memtest showed no errors in seven tests. Drivers are up to date. The system put on fresh after replacing the equipment.

Equipment specification:
Ryzen 5 1600 processor
MSI B350 Mate motherboard
RAM Crucial DDR4 Ballistix Sport 2x4GB
Graphics NVidia GTS450 1GB
Windows 7 Home Premium 64-Bit

On the previous configuration (AMD Athlon 6000+, GA-MA770-DS3, DDR2 4x1GB RAM) and under the same system everything worked without a problem.
Attached memory dumps. I will be grateful for your help.

I know that everyone recommends memtest, but my experience with this program is that it is useless, I wanted to use it when I turned up the RAM, I tried it both from the Widnows level and from a bootable flash drive, it came after a few hours, without errors, but the computer in particular he crashed at random anyway. I even have exactly the same board and processor, by the way, and the code you see is seen dozens of times while playing with RAM.

Make sure that the modules sit in the appropriate slots according to what you have written in the instructions.

See how the situation looks with only one bone inserted (check both in this way).

Update the BIOS to the latest version from MSI, significantly improves memory compatibility.

Specify exactly what RAM model it is and upload the screenshots from the BIOS with the settings (basic settings, i.e. timing and voltage as well as timings), preferably all tabs expand and take screenshots).

Ok thanks for the info. I'll figure it out ... RAM sits in the 2nd and 4th slot. I will translate into 1 and 3 and upload BIOS screenshots tomorrow.

Changing slots did not help. After removing one bone, a blue screen also appeared, now I'm checking the other. The memory is Crucial DDR4 Ballistix Sport LT 2400 CL16. BIOS screenshots:

This error message indicates that there is a problem with interrupts between the bridge and the frame memory or peripheral device connected to the motherboard.

Why didn't you do it: /

You have advanced settings on the disc and that was not what I meant most. And why do you take pictures with a camera instead of screenshots.

For now I'm testing the second bone. I will be updating the BIOS as a last resort, as nothing else will help ...

^ Why as a last resort? This is one of the simplest and fastest steps you can do.

I am not so fluent in the subject and for me it is not the easiest thing. And I'm just afraid of damaging the motherboard.

Ehh, it all comes down to the fact that in the bios you click on a very large button, then choose the file downloaded from the manufacturer's website and that's it. Unless you have sudden power outages and unless you use a damaged flash drive, nothing bad will happen.

I don't know, I've never done that.
Meanwhile, there was a problem on one bone. This time, besides the familiar error, I saw the file name "pci.sys" before the system rebooted.
Below are screenshots from the BIOS. I don't know how it was before, but now RAM works at different frequencies ...

Dude, did you even deign to look at the instructions or enter in Google the name of the disc with the note "bios"?

We'll do a BIOS update. We'll see ...

BIOS update did not help. The blue screen has appeared again.

It wasn't until the system changed to Win10.
