Question I added 2 8GB DDR4 RAM sticks (properly) and now my CPU repeatedly crashes

[Jimby]

I have a MSI Gaming Plus X470 motherboard, AMD Ryzen 7 2700x processor and GTX 1080.

At the moment I had 16GB of DDR4 RAM and wanted to upgrade to 32GB.

I turned off the cpu, flicked the switch and unplugged the power cable. I properly placed the RAM sticks in the 1st & 3rd slots, they clicked in place and correctly plugged everything back in and turned on my pc. That’s when the crap show started.

Repeated BSOD’s, barely getting past the log in and to the desktop screen for a few mins before crashing. My PC recognizes the RAM sticks in “About My PC” as 32 GB but it would not stop crashing.

So, I removed the suspicious RAM sticks and booted up my PC with the previous 16GB RAM sticks. Still, it crashes and crashes.

I tried booting from F1, I tried booting from my Windows 10 CD. It just won’t stop crashing.

Please help me. Thank you.

Do you have the X470 motherboard User Guide/Manual?

If not here is the link that I found:

https://www.msi.com/Motherboard/support/X470-GAMING-PLUS#down-manual

Do verify that I did find the correct manual.

Double check the supported RAM configurations: slots and memory module specs. Page 17.

And on Page 27, under "Important" note the requirement to insert DIMMA2 first.

Kindly define "crashes" (reboots, fully powers off etc), also, provide the full models of all RAM sticks involved.

Have you tried fully clearing CMOS?

Turn-off power supply, remove the CMOS battery, short the CMOS clear jumper for about 10 seconds.

I have a DDR4 RAM stick in the 2nd and 4th slot previous to inserting the new RAM sticks in the 1st and 3rd slots.

Pull the RAM and start with DIMMA2 per the manual.

Again, do verify that the manual I found is correct.

That was already installed ( the DIMMA2 slots). I am having problems after having place an additional 2 DDR4 RAM sticks in the DIMMA1 and DIMMB1 slots

Did you have an XMP profile going when you installed the new RAM?

If you can, boot to BIOS and restore the default. Try again, and or, as suggested above, reset CMOS.

Memory is guaranteed in the form sold. Other combinations you decide to make have no guarantee to be compatible together.

Scroll down to Memory Configurations to see official supported speeds when populating 4 of 4 memory slots compared to using just 2 modules.
