Kernel Panic and system freezes with 4x16 DDR5

I recently added an additional two sticks of ddr5 ram to my system, and it has been a complete nightmare.

I initially figured out it was the ram since this never happened when I was running two. My motherboard simply rejects either AMD EXPO profile both 6000 and 5600 and freezes, in which I need to reset CMOS to gain access.

After disabling expo the system does run for a while, but it will crash at random times, kernel panic error statements vary slightly as it failed to end a specific service. Sometimes there is no kernel panic and just a system freeze, which I suspected was the GPU but ended up dismissing it after appending amdgpu.ppfeaturemask=0xffff7fff or its variants to systemd-boot kernel entries (not silencing the issue). The default non-EXPO speeds for 2 sticks is 4800 and 3600 for 4, which my computer crashes even at base speeds. 'Memory Try It!" still causes crashes but boot at the lowest 5600 preset even though EXPO 5600 preset doesn't. I proceeded to manually change the dram speeds to 5400, 5200, 5000, 4800, respectively and they all still crash within 30min-2hrs of uptime. I have not messed with the dram voltage or timings for these tests (outside of 'Memory Try It!' presets) just the dram speeds.

I switched between Hyprland and KDE Plasma, and the crashes still persisted between the two.

I also test both the current zen kernel and cachyos kernel and they both still crash

I ran memtest86+ for 1-2hrs and had no errors. (could have been too short of a test to verify)

I guess I just need help figuring out how to go about this, or if it is better off to stick to 32 gigs in my situation. I game but also utilize local LLMs and VMs, hence the ram upgrade.

Thank you in advance for the help!

[UPDATE]:

Just after writing this post, I received another kernel panic while just running two sticks of ram:

KERNEL PANIC!

stack-protector: Kernel stack is corrupted in: __schedule +0x15d9/0x1650

[UPDATE 2]

Almost 2 hours of using my computer with the ram configuration (per-channel serial number) for 4 sticks, My KDE Plasma instance froze and I had to hard reboot.

Hardware:

Motherboard: MSI PRO B650-S WIFI
CPU: AMD Ryzen 7 7700X
GPU: Radeon RX 7800XT
MEMORY: 4x16 TEAMGROUP EXPERT DDR5 6000 (1Rx8) CL30-36-36-76 1.35V

Re: Kernel Panic and system freezes with 4x16 DDR5

are the two kits EXACTLY the same? as in: do they share the same model EXACTLY (usually reflect in parts of the serial)? could be you have two unmatched kits - these usually only work with base jedec speed

Yes, they are both identical. I'm confused why this is also happening while running my regular 32 gigs as well. Anyways, it still crashes on base JEDEC speeds.

I just updated bios and double checked the ram, you were right about the serial numbers being slightly off between the kits. I put the modules ending in 207 and 208 in slots 2 and 4, the 508 and 509 in 1 and 3.

Here is my motherboard manual for reference:

Re: Kernel Panic and system freezes with 4x16 DDR5

as for the serial: it's not about what differs but what's the same
usually the serial somehow encode the modeltype (i remember back in ddr3 days a corsair kit hat the model as the first part of the serial, then i guess the batch and last the actual serial - and was quite long therefor) - but doing like you: one kit in 2 and 4, the other in 1 and 3, that's exactly how it should be done correctly
so - from that point - given these are matched kits and roughly within the same area of serial (which hints same model, maybe even same batch) they should work - at least at base jedec speed

but as you mentioned it's not even stable at jedec speeds ... give re-seating your cpu a try - am5 has changed to lga same as intel long time ago - maybe it's a bad contact of one of the memory pins

Thanks for insight, just re-seated the CPU, I noticed right away that booting was faster. I was also able to enable CPU Game-mode and EXPO Profile 2 (5600) with no issues, booting back from BIOS after those changes took half the time as well.

Re: Kernel Panic and system freezes with 4x16 DDR5

so at least 5600 stable then? how about 6000?

Apparently not, my system froze and crashed again. I get a dbus error on boot now and my screen goes blank, regardless of what kernel I pick in the systemd boot screen.

It seems this is just waterfalling into more issues.

Re: Kernel Panic and system freezes with 4x16 DDR5

CPU or other component voltage is too low or unstable? Additional memory sticks may just increase disturbance in entire power bus.

I cannot even mount my root and boot parts in live iso. Cannot lookup blockdev.

This is super frustrating, I'm getting so many issues back to back, and I am not even sure a fresh arch install will help at this point.

Re: Kernel Panic and system freezes with 4x16 DDR5

Sanity check:

I initially figured out it was the ram since this never happened when I was running two.
I ran memtest86+ for 1-2hrs and had no errors. (could have been too short of a test to verify)

The system is stable w/ only the two old or two new DIMMs?

Edit, F5

I cannot even mount my root and boot parts in live iso. Cannot lookup blockdev.

Why not?
The usual suspect is https://wiki.archlinux.org/title/Ryzen#Troubleshooting

while true; do
for ((i=0; i < $(nproc); ++i)); do
    taskset -c $i stress -c 1 -t 360
    sleep 15
done
done

  emulates corecycler which is reported to be able to reliably trigger those problems on windows

I will try adding the cpu kernel parameter for the softlock section of the troubleshooting, the cpu might be the culprit for some of the freezes.

The the stability was about the same for base speeds for running just the two old dimms and all four, system freezes (and/or pixely blue distortion on my second monitor) happen with the system being up for over an hour. Sometimes audio loops if music or a video is playing, and sometimes it simply freezes.

None of the CPU freeze, PSU idle settings, or GPU kernel params have worked thus far.

My main monitor uses display port and my secondary has that HDMI address. I am back to troubleshooting the GPU (and iGPU) to see why HDMI-A-1 indicates a DRM error.

Please use [code][/code] tags.
Nothing there is directly indicating a problem to the degree of a kernel panic.

could however be symptom of a wider problem.
https://bbs.archlinux.org/viewtopic.php?id=309798

Do you not have any issues w/o the HDMI output attached?

But also check

for OUT in /sys/class/drm/card*; do echo $OUT; edid-decode $OUT/edid; echo "================="; done

You'll need https://archlinux.org/packages/extra/x86_64/v4l-utils/

Journal logs dont show for when the computer crashes, at this point I am aimlessly trying to find a solution.

Re: Kernel Panic and system freezes with 4x16 DDR5

just as with the cpu: have you tried to reseat the gpu?
it's been years but back in about 2011 i already tinkered a lot with hardware and just by a tip from friend we figured the pins inside a pci slots have suffered from corrosion and hence made bad contact with the pads on the inserted card - which lead to all kind of issues
these days slot contacts are usually more robust even in more harsh clinates - and anyone remember back in 90s when we use to blow into our cardridges? often it wasn't the blow but just the actual reinsertion what made better contact

Re: Kernel Panic and system freezes with 4x16 DDR5

with or without my dGPu […] the screen freezes

The tail of the journal will be lost when rebooting w/ the power button, if you can use https://wiki.archlinux.org/title/Keyboa … el_(SysRq) + REISUB (bn. that you'll have to explicitly enable that first)
Which of the parameters suggested in https://wiki.archlinux.org/title/Ryzen#Troubleshooting do you currently apply? Do they show up in

cat /proc/cmdline

?
Can you control the CPU voltage or PBO offset in the UEFI?
