full RAM size is not showing on DSM #214

aarpro · 2023-09-12T20:15:33Z

Advantech ASMB-260I-21A1
Atom C3558
RAM 4x16

Arpl version: 23.9.1
DSM model: DS3622
DSM version: DSM 7.2-64570 Update 3

DSM not showing full RAM size (64GB)

When viewing from the terminal - 64GB

When viewing from DSM - only 32GB

and incomprehensible size of reserved memory

I tried changing in the settings file /etc/synoinfo.conf & /etc.defaults/synoinfo.conf
my old values

mem_max_mb="49152"
mem_min_mb="16384"

my new values

mem_max_mb="65536"
mem_min_mb="16384"

The result is negative

I didn't think it might be a loaders problem, but to me gave advice to change loader to ARC. xpenology.com/forum
I have no physical access to my server now, and I can't try another loader

I also found advice to add to cmdline menu, parameter disable_mtrr_trim with null value.
but I not sure that this will not break loading of the NAS

The text was updated successfully, but these errors were encountered:

aarpro · 2023-09-12T21:34:30Z

i add in cmdline menu, disable_mtrr_trim with null value.
and direct boot set to true

result is negative - nothing has changed :(

我没有做任何修改，但似乎不能复现你的问题.

wjz304 · 2023-09-13T20:19:19Z

物理机？

aarpro · 2023-09-13T21:25:28Z

物理机？

yes
But I no have physical access yet.
A few days later I can check RAM and check BIOS settings

aarpro · 2023-09-13T22:22:35Z

物理机？

When loading, I see 64GB RAM, I think this is no problem of memory modules, its soft problems

wjz304 · 2023-09-15T20:11:33Z

Have you made any progress?

aarpro · 2023-09-15T20:20:29Z

Have you made any progress?

no - I no have physical access to the server yet
but i see BIOS 64GB RAM, loaders 64GB RAM - DCM detected only 32GB, and reserved -32GB RAM
so i thunk its is soft problems

In what direction I need to look for?

wjz304 · 2023-09-15T20:34:54Z

I don't know, just a little skeptical. Is it a swap?

aarpro · 2023-09-15T20:43:23Z

swap

What settings can I change to change swap size or over swap parameters ?

zak-forsyth · 2023-09-19T19:43:04Z

What does dmesg say about your memory?

dmesg | grep -i memory

Does it look something similar to this?...

dmesg | grep -i memory [ 0.000000] WARNING: BIOS bug: CPU MTRRs don't cover all of memory, losing 29440MB of RAM. [ 0.000000] WARNING: CPU: 0 PID: 0 at arch/x86/kernel/cpu/mtrr/cleanup.c:972 mtrr_trim_uncached_memory+0x458/0x47f() [ 0.000000] [<ffffffff8190368c>] mtrr_trim_uncached_memory+0x458/0x47f

If so disable_mtrr_trim will fix it.

try to add a fake mac2 to enable netif_num is 2

I have a valid sn/mac and this is added, I see my server on account.synology.com and QuickConnect is work...
on my mb is one GbE Lan

or I have to add the second MAC in any case ? Does this have any relation with the quantity RAM?

I'm not sure,

It's just that I just found someone on a Chinese forum with a similar situation, and after adding a PCIe network card, this situation disappeared

wjz304 · 2023-10-11T07:43:15Z

The data in dmesg and /proc/meminfo are all 64g, so theoretically four slots are recognized,
but dmidecode only recognizes DIMM0 and DIMM1 slots,
This is strange because even if the memory slot is empty, the dmicode should still be displayed.

wjz304 · 2023-10-11T07:49:05Z

This is my machine with two slots, when one slot is inserted.

Win PE AIDA64 detected full (64GB) RAM / 4 slots

take a look at the differences in the details of the 4 slots.

wjz304 · 2023-10-11T08:43:27Z

PS: I don’t know much about these, but I also want to know the root cause. Maybe it can’t be solved in the end, so tests depend on your convenience.

It's the same in arpl as in ubuntu. They do not read the memory-related data of dmidecode.

The same is true in DSM, except that part of the data in the DSM calculation process is read from dmidecode
