Dear all, I’ve been noticing random spontaneous reboots of my TrueNAS (SCALE Dragonfish-24.04.2) but nothing really relevant visible on journalctl when checking what happened just before the reboot… normal stuff like dhcpoffers or containers starting etc. The only thing I could spot is after the r…

Based on a google search of the Record Identifier: 8f87f311-c998-4d9e-a0c4-6065518c4f6d it appears the mostly likely culprit is a memory issue. You may want to run memtest or swap out the ram for known good modules and see if the problem persists.

Just a quick confirmation: memtest found a lot of errors on the 32Gb DDR5- 4800 SODIMM from Crucial… will file an RMA… hope this things do not happen often…

This is why ECC memory exists… Also check RAM cooling in your N305 system. There was a theread about that recently.

well… if the memory would have been ECC it would just have “masked” that it was defective even more… no? And about the cooling: do you mean that when temperature rises it might create memory errors? that would be even worse no?

[image] tent: if the memory would have been ECC it would just have “masked” that it was defective even more It would detect and log errors, but not crash the system.

well yes fair… anyways from my understanding if I buy ECC DDR5 it would not be supported by my system cause it’s i3 alder lake, correct? I’d need to have a i5 (but that one would be even hotter… also since noise should not be a big deal I could put a nice fan on top of the fans of the system if tha…

another kind of curious question about DDR5 SODIMMS: is it normal I don’t find/see 64Gb ones? Maximum seems to be 48Gb? (I have only one memory slot, so maybe an upgrade to 64Gb would be sweet…)

Intel states that the max memory size for the N305 is 16GB. While that doesn’t necessarily mean bigger won’t work, you’re off the reservation and relying your motherboard dealing with it well.

really? the vendor of the full system states 32Gb and they work… actually my question was more like: is it normal that amazon nor others list 64Gb DDR5 SODIMMS? They are still not on the market I guess? Back to the heat topic, I could not spot the thread that was talking about alder lake i3 and he…

As reported in the thread @Okedokey references, I was having similar issues with random reboots and escalating instability. When running DDR5 RAM at 4800MHz the system would fail memtest. I replaced the RAM and the replacement RAM also failed memtest. I returned the original N100 motherboard and …

The thread was about confined DDR5 memory modules getting hot and causing errors. When cooled sufficiently or downclocked the errors went away.
