Did the limits for RAM on Home edition get changed with SFOS 16.05.2 MR2? I'm only seeing 4GB after update. Still only showing 4GB after rolling back to SFOS 16.05.1 MR-1. I was seeing 6GB usable before upgrade.
Let's dig in and see if we can find something.
Post output by running two commands in the console.
console> system diagnostics show memory
console> system diagnostics show cpu
I see JD MaC has a point here, are you guys experiencing this on a hardware appliance? The above command will fetch the hardware information for us.
Finally, a memory test. Refer: https://community.sophos.com/kb/en-us/125025. Note: It may take 1-2 hour time to complete a full scan of 6 GB. Post the output.
Thanks

System has 8GB installed (2 x 4GB).
Was using 6GB before upgrade from 16.05.1 MR-1 to 16.05.2 MR-2

Memory diagnostics in Sophos Firewall (SFOS)
Sorry, but that is not going to be possible anytime soon.
Was using 6GB before upgrade from 16.05.1 MR-1 to 16.05.2 MR-2. Nothing wrong with my hardware, unless XG whacked my BIOS!
=====================
Hi David,
The limit is 6GB RAM and not 8 GB. Use a 4GB RAM and another 2GB of RAM instead of 2x4GB and let us know if that makes a difference.
Thanks

Wow!!!! Read your own documentation.
"Home Edition is limited to 4 cores and 6 GB of RAM. The computer can have more than this, but XG Firewall Home Edition will not be able to utilize it."
https://www.sophos.com/en-us/products/free-tools/sophos-xg-firewall-home-edition.aspx
After running a over a year with 8GB physical and utilizing 6GB all of a sudden this is not supported!!!
Please clarify.
Hi David,
I just wanted to verify if 2x4GB RAM caused the issue and we are on the same page. Only 6 GB of RAM is supported by the XG home edition.
Patience will be appreciated.

Ok, thanks. I don't have a 2GB stick laying around, just to test.
Note that another poster has a single 8GB stick and is seeing the same 4GB limitation all of a sudden.
Just to put it out there ...
This has all the symptoms of a licensing issue.
Given that the problem remains after rolling back to MR-1. It doesn't appear to be in the OS. It smells like the licenses were modified, 'downgraded', upon applying the MR-2 update.

Ok, is this really necessary? This test the physical memory by running a test pattern. I feel pretty comfortable saying that everybody's memory didn't go bad at exactly the same time.
Mine's brand new and i ran clean across 2 full passes in memtest. I always run memory/stability tests before relying on a new system.
And as i mentioned booting the system to any other linux distro shows 8G of ram. Bios shows 8 G of ram. dmidecode shows 2 x 4G.
My only guess would be something in the kernel changed how it deals with memory. it's basically like i don't even have a second stick of memory.
Was there a kernel update between 16.05-MR1 and MR2? Does it fall back to a previous kernel if you tell it to use MR1 again or is that only switch the userland OS
Maybe the kernel can't map the second dimm due to the ram=6G, but that's only a guess.
Has anyone using a single 8G dimm reported the same issue?
Just in case it's CI323 related mine's brand new barebones from newegg, I installed memory and SSD.

The bios version is below

Yes ... see previous post here.
Single 8GB and seeing same issue.
