Also, Windows 10 Home 64-Bit

Describe your problem. List any error messages and symptoms. Be descriptive.

To preface, I just built this system yesterday, and there's no real software on it except Windows updates and web browsers.

First problem is I cannot use all four of my RAM DIMMs while utilizing the XMP profile for their advertised 3733 speeds. When attempting to do so, the EZ Debug LED for CPU is a solid red and the system never posts, it just runs the fans and LEDs.

If I run all four DIMMs at 2133 mhz it boots just fine, or if I use two DIMMs at the 3733 it also boots just fine.

Once it boots to the OS, with the aforementioned RAM settings, I'm experiencing 5-20 second freezes while using the OS, relatively consistently, I'd say at least once per five minutes, more often at times. Running Open Hardware Monitor shows that my CPU is not getting close to maxing out.

Also, several times, while in the OS, the PC freezes indefinitely requiring a hard power cycle. There doesn't seem to be any specific thing that triggers this, but I have noticed that doesn't seem to happen while it's idle. I've also been copying files from one HDD to a second HDD and so far it hasn't froze during that.

List anything you've done in attempt to diagnose or fix the problem.

I've tried using a new B450 MSI Gaming Pro Carbon AC I had lying around and experienced the exact same issues with not being able to boot with the ideal RAM configuration. I didn't run the OS using the b450 long enough to specify whether the freezing issues occurred.

I've installed the latest bios on my x570 motherboard and it didn't resolve any of the issues either.

Post relevant photos of build/parts here.

I'll take photos upon request.

Provide any additional details you wish below.

This isn't even close to my first PC build, I've done at least 20 over the last ten years or so. I'm not exactly a professional or anything (though I do have my A+ certification), but I wouldn't consider myself a novice.
 
To run your RAM at the advertised 3733 speed have you enabled "A-XMP" in the motherboards BIOS?

What is your EXACT Model RAM kit ?
Is your EXACT Model RAM kit listed on the MSI Memory QVL ?
https://www.msi.com/Motherboard/support/MPG-X570-GAMING-PRO-CARBON-WIFI#support-mem-19

If not it may not run at it's rated speeds.
https://www.newegg.com/corsair-32gb-288-pin-ddr4-sdram/p/N82E16820236484

CMW32GX4M4K3733C17

And it is on their QVL listed under the Memory by RX-3X00 section.

Also, it runs at advertised speeds when there are only 2 DIMMs at a time. I tested all four DIMMs in a 2x8 configuration and it works. I've even tested channels slots 2/4 and 1/3 on the mobo, and it works. It's only when I have all four in at 3733 mhz that it doesn't boot. Still, even if it boots with two DIMMs at any speed, I have massive freezes while attempting to do anything on the PC.

Actually, nvm, it's only on their QVL for 1|2 DIMMs, not 4...

That's quite upsetting. Well if we're going to chalk it up to that being the booting problem, there's still the massive freezes during OS. Any ideas?

Have you checked to make sure that your cooler isn't overly tight?
That can cause issues with RAM.
Also have you checked to make sure that your CPU doesn't have any bent pins?
You should also install 1 stick of RAM in the second slot from the CPU and then run Memtest86 and repeat the process with all four sticks to ensure that one or more of them isn't faulty.

Yes, there was an XMP profile for the advertised speeds that I used to set the speed. Apparently my RAM isn't on the QVL for 4 DIMMs, but even with just 2 DIMMs in, I am still experiencing massive freezes during the OS whenever I do anything on it. Any idea?

I haven't checked to make sure that the cooler isn't overly tight. I honestly didn't know that was a thing. I did check the CPU for bent pins. Could having faulty memory be what's causing the massive freezes during computing?

Since they are not guaranteed to run at their rated speeds with four sticks installed I would try them at a lower speed like 3200 MHz.
If they work at 3200, then try them at 3333 MHz and so on until they fail to pass Memtest86.
And yes having faulty RAM or RAM running at to high a a speed which makes them unstable will cause freezing and BSODs.


How long ago did you purchase that RAM?
If possible I would return it and buy a 2x16 GB kit that is listed on your MB QVL.
Four sticks of RAM stress the Memory Controller a lot more than two sticks which is why they tend to run at much lower speeds.

Check this thread out, another member just figured out that having his cooler too tight was the cause of his RAM issues:

Running 2 DIMMs at 2133 seems to have greatly lessened or eliminated the freezing. This is a pretty big bummer, 3733 is supposed to be a pretty big sweetspot for Zen2, not to mention I paid $500 for this RAM :/.

I seem to be running into other, perhaps unrelated, issues. Like not being able to install my RTX 2080 drivers. I'm going to do an OS reinstall, as the OS that's installed on this hard drive was actually done on my test motherboard (the b450), and though I don't know if that's having issues, something is definitely going on, and may as well try a reformat while there isn't really anything on the OS drive.

As a habit, I remove all additional hard drives from the system when I do a reinstall (pull the sata cables) in your experience is this necessary? I've found in the past that sometimes during the install process it'll spread out, various files to different hard drives, like the clean reinstall backup, for example. Am I being paranoid, or is this considered best practice?

Yes a clean install with only the HD/SSD you want Win 10 installed on is definitely the best way to go.
And the fact that your Windows installation was done on a different motherboard could definitely cause issues with your current build.

I did a fresh install on the x570 and everything was working fine except I couldn't update my RTX 2080 drivers, I found out it was due to windows installing the universal driver and then not letting it be replaced. So I forcibly removed it with DDU (Display Driver Unistaller) in safe mode and installed the latest drivers via executable. Then all the problems started again, this time worse. I'm starting to think this motherboard is kind of shit. I'm in the process of reformatting again from scratch and letting the universal display driver install and seeing how the OS runs with that (it seemed relatively fine before, but I didn't do a whole lot with it)

I've been continuously looking into this and it seems others are having the same issue due to an AMD Zen2 problem indicated here: https://www.reddit.com/r/Amd/comments/cbls9g View: https://www.reddit.com/r/Amd/comments/cbls9g/the_final_word_on_idle_voltages_for_3rd_gen_ryzen/


Do you think this could be the cause?
