WHAT IS USEING 80GB OF RAM 2017 IMAC!!!!!!!!!

[pianojoe]

Are you running out of RAM in any way?

The thing is: If there is unused RAM available, and the system can be sped up by using said RAM for caching, this is exactly what will happen. The moment the RAM is needed by another process, it is freed and made available.

From the images, memory pressure is all green. I wouldn't worry about it...

But I'd still pull 64GB out.

I know there’s some Apple executive reading this thread thinking “Why did we make the RAM user accessible” 🤦‍♂️😂

Edit: Apple’s spec sheet on the 2017 iMac says 64 GB of RAM was available for BTO. So it was available day 1 as I remember.

I have a 2017 iMac bought day 1. I paid to upgrade the RAM myself to 32 GB within the first week or so.

I remember there being 64 GB available as well as I wanted to max everything out but couldn’t justify the insane price even from 3rd party RAM.

I have no proof to back this up unfortunately so all I can say is trust me and that I feel 90% right on this.

Idk if I'm tired and misunderstanding something but 64 was definitely available? 128, no

OP doesn’t even understand the difference between 2017 and 2019 iMac. Why are people going to extreme lengths to try and make OP realize they’re confused?

People here are trying to be helpful. Some people need more effort to be helped than others.

One thing that I discovered is the 'weight' on your system depends on what software you use to virtualize the Windows you are using. Some systems sit heavier than others. And even without using the VM, the 'weight' can still be there to a point.

Also the memory figures you are seeing could also include swapped bits Into the swap file on disc. The whole idea of swapping memory is to have more memory than you actually have because most of the crap isn't used on a continuous basis. It's amazing, the actions of little programs running to insure the survival of the system. Pretty cool, when it works... When it doesn't, it all falls down.

Basic summary of thread: OP can't do proper research, buys something that will never work, complains that it doesn't work. Everyone else does proper research, many of them share links to the research, and are told "nuh uh!" by OP. OP shares more incorrect research (2019 instead of 2017) to support original position, keeps complaining about how they've seen 40-50 people running 128GB ram in their 2017 iMacs (no evidence provided).

Even shorter version:

OP asks question. Gets answer he doesn't like. Gets upset at those giving him facts that back up that answer.

I knew by the title that this thread would never end well...

I'm more vested into what caused that sudden jump in memory consumption (consuming all 64GB) versus the 128GB he incorrectly installed.

 

[johnsc3]

That doesn't seem to be true, given that Windows won't use more than 64GB either.

He doesn’t wanna let it go-lol.

64gb is the limitations imposed by the cpu/chipset you whatever. mac windows linux would still be limited to 64gb. It’s a hardware limitation. macos/win are only showing 128gb available based on dimma1/a2/b1/b2 and ram reported config.

Why is this conversation still going on? Intel themselves says max memory supported is 64GB. Unless Intel. Apple and others are lying according to the OP? This should be the answer and be done with the conversation. If the CPU cannot support it, it cannot support it.

you are right it was only advertised for 64

 

[Kpjoslee]

you are right it was only advertised for 64

and totally hardware limited. you can't get 7700k to utilize more than 64GB on any OS. It is a processor limitation.

Just as an FYI, here is the Intel i7-7700K Tech Specs

 

[profcutter]

Yeah, an activity monitor screenshot is suspiciously absent.

 

[Shirasaki]

Well, guess until OP figures out the actual reason this thread might go a bit longer.

Actually reminded me to check similar stuff on my PC.

Hope we can see an activity monitor screenshot after removing 64GB of unsupported RAM soon.
