What can I actually do with 64 GB or RAM?

Run a local LLM

700 Chrome tabs, a very bloated IDE, an Android emulator, a VM, another Android emulator, a bunch of node.js processes (and their accompanying chrome processes)

Here's what you can do with your impressive 64 GB of RAM:

Store approximately 8.1 quintillion (that's 8,100,000,000,000,000) zeros! Yes, that's right, an endless ocean of nothingness that will surely bring balance to the universe.

The best thing about having a lot of RAM is that you can have a ton of apps open with a ton of windows without closing them or slowing down. I have an unreasonable number of browser windows and tabs open because that's my equivalent to bookmarking something to come back and read it later. It's similar to if you're the type of person for whom stuff accumulates on flat surfaces cause you just set stuff down intending to deal with it later. My desk is similarly cluttered with books, bills, accessories, etc.

Be in virtual machine heaven

Keep it and wait for the applications to bloat up. You won't feel like you have an excessive amount of RAM in a few years.

I used to have a batch file to create a ram disk and mirror my Diablo3 install to it. The game took a bit longer to start up but map load times were significantly shorter.

I don't know if any modern games would fit and have enough loads to really care..but you could

Depends.. If it's DDR5 it might not work with the other stick.. I was unable to add on another 64GB to my desktop a last year and had to eventually just buy a whole new 128GB set.

You could build another computer/server and self host things..

You can run AI Models in it. Probably ones with 70b or up to 60b of you want to do other stuff while running them.

I built my PC recently and splurged to get about 100gb of ddr5, thinking it was going to be a waste of money.

I couldn't have been more wrong, there are occasionally times when I'm almost running out of memory. How? Multiple desktops, each with tons of programs and stuff open, including probably like several hundred Firefox tabs open at the worst of times.

Basically, extra ram has allowed me to kinda postpone the responsibility of having the close programs, maintain cleanliness, etc. I still have to stay organised using desktops so I don't go crazy with the number of things I have open, but I'm the limiting factor here, not my computer. And that's a super liberating feeling.

TL;DR: you can NEVER have too much ram.

Does it have RGB? If not just bin it. It is worthless anyway.

Unused RAM is wasted RAM.

Open 10 extra tabs in chrome

Sell it to somebody at a medium, medium cost who needs it

I used it for virtual machines and Docker containers.

You could run a Java program, but you'd quickly run out of ram.

• Compressed swap (zram)

• Compiling large C++ programs with many threads

• Virtual machines

• Video encoding

• Many Firefox tabs

• Games

I have 16 GB of RAM and recently tried running local LLM models. Turns out my RAM is a bigger limiting factor than my GPU.

And, yeah, docker's always taking up 3-4 GB.

Run a fairly large LLM on your CPU so you can get the finest of questionable problem solving at a speed fast enough to be workable but slow enough to be highly annoying.

This has the added benefit of filling dozens of gigabytes of storage that you probably didn't know what to do with anyway.

Keep (checks math) 3 more tabs open in chrome.

You could make /tmp a ramdisk which probably has some speed benefits.

If you are on Linux and I guess windows but nor sure. You already use it for cache. So you can never have enough ram. As long as it's the same speed of your existing ram or you will screw yourself in preformence.

Qubes OS

You never have to close a browser tab again. If a window is full just minimize it and start a new one!

Open 1000 instances of vim

Store your Firefox profile and all tabs in RAM for snappier browsing: https://wiki.archlinux.org/title/Firefox/Profile_on_RAM

I can take 'em off your hands. Three fiddy.

im sorry but you can't do anything with it i guess you're fucked

Photogrammetry (with Meshroom) or 3D scanning (point cloud alignments and processing has some beast requirements).

Meshroom would gladly use any resources it can find within a 20 mile radius.

Run a LOT of VMs

Same thing you can do with half a hole. Fix it to keep your mind from wandering.

Run the Adobe suite, crackled of course.

Run Minecraft and YouTube twice over.

Figure once over is why I moved to 32, so twice over might need more.

Depends a lot. If you are going from 2 ram slots in use to 4 ram slots in use, usually the max clock speeds go down a lot. So the performance will decrease for just about everything you do, whilst the use case for such a setup is very limited.

I have a couple of extra ram sticks to get from 32 to 64gb when I need it. I bought them because I was debugging a rather memory intensive tool. Not only did the tool run in debug mode, which added a lot of overhead. The memory profiler needed to be able to make memory snapshots and analyze them. This just about doubled the memory requirement. So with 32GB I often ran out of memory.

However my Ryzen 5950X does not like 4 sticks of ram one bit. Timings need to be loosened, clocks need to be reduced and even then the system would get unstable every now and again for no reason. So I pulled out the 2 sticks going back to 32GB as soon as the debugging job was done. They are in a drawer in an anti static bag, should I need them. But for day to day 32GB with 2 sticks is a much better experience.
