What did you think @JaxJiang ; is this Memory supported with maximum MTS? 2Rx8 KVR56S46BD8K2-96 (Kingston 96GB Kit)This problem is hard to traking. Currently we recommand using kingston RAM if you want to run 5200Mhz.
There is no any report of memory issue from kingston RAM.
In your case I would return your crucial memory directly and buy the Kingston from my latest posts. You don’t have to lose anything.I would also like to know which Kingston DIMMs are recommended. I have 2 days to return these crucial DIMMs.
I have two units, same HW-setup in both, no changes to BIOS settings except secure boot off (13900H CPU / 1x NVMe / 64GB RAM)I still get random hangs while using Bios v1.24, micocode 0x4121, and crucial DIMM.
The most recent was this morning after 5 days. Memory speed has been lowered to 4400.
The last thing I did was disable ASPM for the 2.5G network ports.
Usually, when the random hangs happen, the fans run at full speed and the computer becomes unresponsive, and I have to unplug the electricity and restart again.
For those people running Bios v1.24, do you disable ASPM for the 2.5G network ports? Also, do your fans also run at full speed when you get random hangs or reboots?
I would also like to know which Kingston DIMMs are recommended. I have 2 days to return these crucial DIMMs.
Can you try to remove one dimm for test ? I have stable work for month after this on 5200 memory speed, slot closer to cpu is stable, far from cpu have random hangs.I still get random hangs while using Bios v1.24, micocode 0x4121, and crucial DIMM.

Hi. Thanks for your report.I still get random hangs while using Bios v1.24, micocode 0x4121, and crucial DIMM.

Thanks for your report.We will keep an eye on thisI have two units, same HW-setup in both, no changes to BIOS settings except secure boot off (13900H CPU / 1x NVMe / 64GB RAM)
Still running BIOS v1.17 + microcode, changed grub settings:
GRUB_CMDLINE_LINUX_DEFAULT="quiet pcie_port_pm=off pcie_aspm.policy=performance"
I also had lockups, with fans speed ramp up, but looking at the logs in the running VM's they would log the crash at the same time that I powered off the host. Did the GRUB mod to see if it was some sort of power saving that made the 2.5 nics go to sleep and not be able to wake up again. So far so good. No issues the last 13 days..
Unfortunately I can't try this anymore with the 48GB DIMM. I've just returned it. I'm using the crucial 2x16GB DIMM back at 5200 now that comes with MS-01. I wanted to test if the issue persist.Can you try to remove one dimm for test ? I have stable work for month after this on 5200 memory speed, slot closer to cpu is stable, far from cpu have random hangs.
Thanks. I'll try the following then:Hi. Thanks for your report.
Our BIOS enable ASPM on I226-V/LM default.
If downgrade memory speed and problem still. I strongly suggest you contact after-sales service to exchange or return the product.
Our tested kingston ram part number is: CBD56S46BD8HA-32. I am sorry currently there is no any kingston 48G RAM data.
Your Crucial 48G RAM part. We are investigating the issue.

Update from my end: Running since 5 days + 19 hours without crashing. Def a new record, will update again soonJust flashed the BIOS 1.24 and lowered the RAM frequency to 4400. Now its time to go past 1 week uptime. Fingers crossed!
Could you help try 1.24 TEST BIOS for RAM SPEED downgrade?Have had a couple of failure events now...
Node 2 gets fenced - VMs move to another node and all works as expected so not major.
All three have good resources and not overloaded -
do see a CPU sustained load overnight into AM hours - possibly its just CPU hitting a no go point....

96g ram - issue is I don't have a Switched UPS... and couldn't get the RMM working on the MS01s before I deployed them
so 1000+ miles away physically - have to reboot the UPS and take the network down to get the failed host back online.
Seems to be the same node every month now.
Pretty sure I have the microcode installed on all three nodes
humm... used the promox helper scripts when I setup but possibly during upgrades it got modified again.
Affected nodes before update:
# journalctl -k | grep -E "microcode" | head -n 1
Jul 20 15:13:21 pve02 kernel: microcode: Current revision: 0x00004121
Ran their script:
✓ GenuineIntel was detected
✓ Intel iucode-tool is already installed
- Downloading the Intel Processor Microcode Package intel-microcode_3.20240514.1~deb12u1_amd64.
✓ Downloaded the Intel Processor Microcode Package intel-microcode_3.20240514.1~deb12u1_amd64.deb
✓ Installed intel-microcode_3.20240514.1~deb12u1_amd64.deb
✓ Cleaned
In order to apply the changes, a system reboot will be necessary.
# reboot
# journalctl -k | grep -E "microcode" | head -n 1
Jul 20 16:13:33 pve03 kernel: microcode: Current revision: 0x00004121
same result so expect thats not the issue I'm hitting.
lots of these - I'm betting my thunderbolt mesh is jacked up...

Not fully related but could confirm for the Kingston.This problem is hard to traking. Currently we recommand using kingston RAM if you want to run 5200Mhz.
