RouterOS x86 Max Memory

Hi All,

What is the maximum memory that you can have with RouterOS V6 on an x86 Platform?

Regards

I can’t speak specifically to RouterOS, but all x86 platforms are limited to a max of 4GB RAM if they don’t support PAE. Since ROS is Linux-based, and Linux has had PAE for a LONG time, it may support more than 4GB, but there aren’t too many applications that would require that much.

2GB

That settles that!

Probably not the case for the original poster, but I just wanted to mention that CHR uses 64-bit instruction sets and can utilize much more than 2GB:

“Minimum 32MB of RAM (maximum supported 2GB, except on Cloud Core devices and CHR installations, where there is no maximum)”

I wonder why CHR (IMG) version support x64 but original ISO version not.

x64 hardware was not very common (especially with regard to network infrastructure devices) when the original x86 ROS was developed. MT developed for the more common platform. Now that almost everything manufactured is x64-capable, and it’s more common to see open systems (x86_64) running a variety of routing platforms, combined with the prevalence of private and public cloud infrastructure, they built the new CHR to work in what’s now the new norm. I honestly would expect that within a few years, they’ll probably stop all work on the standard x86 version.

apparently CHR become major MT platform for x86 ROS. just marketing priority i guess(and balancing of worktinme/expenses in lesser scale).
but MT instead can “extra charge” for extended features of x86 versions. that may had 64-bit version, newer stuff in or other unusual(yet) improvements inside it. just in case if only money - cause for original concern.

There were several years since last post.

I have a GOOD SERVER to use as BGP peer gateway (lot of Intel cores and about 32-64GB RAM).My problem is I use a CCR1072 and my customers spend more the 6 GB de traffic and CCR hat 10GB Interfaces.

I read old posts.
I read there is a restriction un x86_64 virtialize server with 2GB RAM.

Is it true?

there’s a way to enable support for more ram.
i have an installation with 24GB RAM, and ROS sees it all.
there was a 6.3x version rc that enabled switching on 64bit support, and afterwards all subsequent upgrades retained this setting.
i am however sure that this is not supported at all.
it does run a bunch of kvm based servers: routeros guests, linux and freebsd guests.
