RAM

Hi all, how can I resolve ram modes?
I have mobo MSI x99 sli plus, intel I7 processor with 32 GB of ram (corsair vengeance 8GB X4 modules), please help with this treat


Thank you

No idea what you mean by "resolve ram modes"...what are you trying to do?? What do you mean, and on what version/distro of Linux??

the operating system is Ubuntu 22.04 lst, I recently add two more RAM modules to my PC, searched over the UEFI and cant see the mode of RAM, it is working in quad channel or not ....

Unless you're running server-class hardware, no..probably not. A vast majority of systems are dual-channel only...and the way you can find out if your MOBO support this is to read the manual on it. This isn't a Linux issue, but one of your MOBO hardware.

Yes, MOBO supports dual, triple and quad channels .....

sudo lshw -short -C memory

Thanks for your replay, but it shows only slots where dimms are installed in there, more detailed view of this point is this command, sudo dmidecode --type memory.
my question is different, is alternative software like CPU-Z on WINDOWS for Ubuntu??
CPU-X does not show information what I need.

AGAIN: you can find this out by looking at the manual for your motherboard. Amazingly, if you tried to put "MSI x99 sli plus" into a search engine, you'd find the MSI website with specs for your motherboard...and you can read the answer there yourself.

Do basic research first

On my system it shows quite a lot e.g. memory frequency which you won't learn by reading your mobo manual, and memory type too of course. Perhaps you hardware is not yet supported by your distribution and you need to upgrade. And you can run it without --short and see even more.

Depends on what do you mean by that - GUI? I hope not.

Thanks a lot, as I guess only solution is to run memtest86+, it is really slow process but.....

there are at least 10 different tests (in memtest), most of them are fast, a few of them are really slow. You do not need to run all of them.

You must purchase RAM hardware that is exactly compatible with your board. It sounds to me like you didn't. Probably, you can exchange it with whoever you bought it from.

Hit up in terminal

inxi -h

Lots of options in that command

example only

inxi -zv7

above command will show some memory info.

Your probably running into this issue because it is quite normal for motherboard manufacturers to require matched ram modules I know that on my HP Z420Work Station for instance.

You have to start with dims in slots 1&3 and end with slats 5&7 which means that for my machine you would fill odd numbered slots first and then do slats 2&4 and slots 6&8 and I can't put anything above 64GB of ram in my machine so its either eight eight gigabyte dims modules or ecc or non ECC unbuffered/buffered ram or 4 16GB modules.

Which is what sundialcvs said previously. And telling them which slots to use may not work since (unless you read the manual for THEIR motherboard), they may have a different population method.
