Not using > 1TB Ram

Post by splat-man » 2022/06/09 19:36:38

I have a System Centos 7 has been running with 768GB of Ram for a couple of years now . added 512 GB ram to bring itthe 1.25 TB of ram.
Installed it no problem , the Mother sees it , lshw sees it , However the OS is only reporting using 1TB of ram

I'm sure it is something simple I'm missing. But I can't figure it out

Code: Select all

[root@xtc kernel]# lshw

Post the output from dmesg -T | grep -iE "mem|ram"
CentOS 8 died a premature death at the end of 2021 - migrate to Rocky/Alma/OEL/Springdale ASAP.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are dead, do not use them.

[Tue Jun 7 15:48:20 2022] BIOS-e820: [mem 0x0000000100000000-0x000000ffffffffff] usable
This appears to be the highest number reported by the BIOS e820 call and I make that 1TB give or take a byte or few. I'd look at BIOS updates and/or reporting the problem to the motherboard manufacturer. You could also try appending mem= to the kernel command line and see if that works though I would do that from the grub menu at boot time as a one-shot to make sure it works before you edit grub.cfg and make it permanent just in case it does not work at all.

OK, I'll see what I can do .

what wouldthe Syntax of the appending memory be ? I want to make sure I do it right


also The Bios see the 1.25 TB of mem

when I do an lshw it shows the memory

Linux relies on e820, other tools may resort to other means.

Did you follow the memory population rules from the manual? My guess is that you now have 20 DIMMs @64GB each. There is only one correct way to install them.

See /usr/share/doc/kernel-doc-3.10.0/Documentation/kernel-parameters.txt (part of kernel-doc) and search for mem=
mem=nn[KMG] [KNL,BOOT] Force usage of a specific amount of memory
Amount of memory to be used when the kernel is not able
to see the whole system memory or for test.
[X86] Work as limiting max address. Use together
with memmap= to avoid physical address space collisions.
Without memmap= PCI devices could be placed at addresses
belonging to unused RAM.
