So im not sure what the issue is but htop and neofetch are both showing I have 27.11GiB of available ram. That would come out to about 29.1 GB but I have a total of 32 GB of ram and I double checked in my bios and it says 32.1. Is there a reason why this might be?

[Bro]

Self-explanatory.

Don’t Panic!

Your ram is fine!
https://www.linuxatemyram.com/

[Alkaizer]

Im aware of this and again this doesnt explain the problem. Even when I run free -m this is the output I get

               total        used        free      shared  buff/cache   available
Mem:           27765        3154       22883          76        2180       24610
Swap:          58290           0       58290

im still missing a few GiB of ram

[Bro]

You don’t know how to convert.

GB to MB Conversion Gigabytes to Megabytes Calculator

Either that or you got royally screwed. Which do you suppose it is?

[Bro]

Manufacturers use a different measurement standard in order to puff-up their feature lists. They always use the highest number. Always.

I got 2 1TB SSDs, right? Not so!

True size is 931.5 GB ea.

[Alkaizer]

I understand the conversion and I did them correct. I also know when buying an SSD that you dont actually get the full amount. Its always less thats why im not talking about my 1.8 TB SSD thats supposed to be 2 TB or my 1 TB SSD that is actually 915 GB. This strictly the RAM im having the issue with and something seems off. Again in my bios is specifically reads as 32,xxx memory. I know that GB is different frim GiB but the conversion isnt adding up and even when running free -m you can see the total isnt what it should be.

I have garuda running on my other machine with 32GB or ram and it isnt having this issue

[Bro]

Again, either Linux Ate Your RAM (fanciful thinking), or you got screwed.

Go complain to whomever you bought it from!

I’ve been running Linux for more than a day–more than 9,125 days–and this I know about.

[Bro]

Thank you for such a charming appellation. I’m also known around the Arch flora & fauna as @c00ter.

But–hey–I can add, subtract, multiply, etc.

A great skillset you should think hard on acquiring!

[Alkaizer]

Please tell me more about yourself. You seem like the kinda guy that just loves to talk about himself all the time. I bet you do wonders at birthday parties.

[Bro]

Sorry, Mr. Boring. I only tell “And then I ate the bear” Alaskan stories to non-boring friends.

Ever had one in your living room? I had Mama & 2 cubs.

They’re scary.

[Alkaizer]

You know what you call a Bear with no ears?

[Alkaizer]

I booted up a live USB of Manjaro just to see if it would spit out something different…it didnt. Gonna go with the case of manufacturer skimped on the RAM. Honestly it threw me off cause this was the first time ive experienced this with RAM. Might just swap it out in the future but I dont think 2-3 GB will be an issue for me.

[Bro]

Truly, it’s a manufacturers gambit. Here’s an example from way back…

Manufacturers use 1,000,000 bytes to represent 1 MB. So, say my old IBM Mod. 30-286 had 1 MB of RAM, and I added another to make it 2 MB, right? 'Cause 2 x 1,000,000 equals 2,000,000 bytes or 2 MB. And this is the manufacturing standard all computer & peripheral manufacturers use for RAM, HDD, SDD, NvME, you name it.

But not so because a true MB is 1,048,756 bytes. And a true 2 MB would equal 1,0488,756 x 2 or 2,097, 512 bytes.

So, from a user-standard, it looks like I got screwed. But from a manufacturer’s standpoint, I got exactly what I paid for.

So that was the real world for @Bro in 1988.

Same for the 2 IBM Blue 1 TB SSDs I bought this year. They’re actually only 931.5 GB SSDs.

Oh… and “B.”.

[Alkaizer]

Yeah I understand this and know how manufacturers like to use different metrics. Honestly I know you deal with a lot of people that probably dont know this and so it came off a little condisending. My issue was that on my rig at home ive got 31020 MiB of memory but my laptop with supposedly the same amount of ram has significantly less. 27.11GiB. I was thinking either my ram might be bad or it wasnt reading it correctly. In the end I think the manufactuer just skimped out on the ram even more so than youd expect. Ive got 4x8GB corsair vengence in my rig, not sure what brand is used in the laptop im having the issue with but im gonna take it apart and find out so I avoid it in the future.

[Alkaizer]

Lmfao yeah its “B”. Heard that joke this past Friday during Primus, APC, and Puscifer. Maynard had all the dad jokes, idk why but that one tickled me

[Bro]

I may have invented dad jokes. I have a great grandchild.

The cornier the better. If they don’t elicit a groan, they’re not real.

It took me years to figure out why my dad loved Professional Wrestling.

@Alkaizer

Hey Bro, idk if you remember our lovely conversation about how my RAM wasnt showing the correct amount but just so you know im an idiot and just had a lightbulb moment last night. I found the manufacturer serial number and dug deeper and found the technical specs for the ram and everything looked good. I was still scratching my head why 4 GB or RAM was short because it just seemed like way to much for your typically manufacturing cutting corners.

Then while looking at my fastfetch I realized just how oblivious I was. I have an igpu and a dgpu…the igpu had 4GB of VRAM dedicated to it. Anyways hope you get a good laugh from that. Idk why I didnt think about that but I guess we were both wrong on why it was showing less than it should.

Either good research or a great late night brain fart. Either way, @Alkaizer self-solved.
