full RAM size is not showing on DSM

[aarpro]

• 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

[aarpro]

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.

物理机？

[aarpro]

物理机？

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

[aarpro]

物理机？

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

[wjz304]

Have you made any progress?

[aarpro]

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]

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

[aarpro]

swap

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

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.

I can't understand how to do it :(

'value' does not need to be filled in

[zak-forsyth]

What they said. No value for mtrr trim.

I understand correctly that displayed Reserved -32325344KB (minus!) This is only a display in DSM

I just don't pay attention to 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

[aarpro]

I'm not sure...

no, It did not help, all the same

[wjz304]

Okay, if it doesn't affect usage, don't attention to it first
