    How much RAM does your PC really need?


    Is there a case for more than 8GB of RAM? Sure there is, but the bang for the buck trails off.

    Here is a definitive guide to how much RAM your PCs needs.

    Note that how much RAM, along with the type and speed, that your system supports will depend on your motherboard. Consult your PC/motherboard manual, or, if your PC was manufactured by an OEM, use a system checker such as the one found on Crucial.com to find out what RAM is compatible with your system...

    I always felt that for most users 4gb was the sweet spot and for users that did a lot of multitasking and need a bit more performance then 8gb is the sweet spot. I have 8gb and I'm happy with it.

    For graphic work or CAD work.. I would get 32Gb.

    As a PC gamer I would put 8GB as the minimum and 16GB as safe. I have seen plenty of games recently pushing and even surpassing 6GB of RAM usage.

    I have an odd case where using more RAM on an x64 system actually benefits my audio editor (even though it's and x86 application)

    I first noticed this when I switched from XP over to XP x64. When I opened a large wave file in RAM, I originally could only open about 1:30 (hh/mm) in length, but on an x64 system, I could manage to open a two hour file. All I can muster as a guess is that the application gets access to an entire four-gigabyte memory block on an x64, whereas on a 32-bit system, that address space is shared with the OS and hardware region just below the 4 GB boundary. But whatever the reason, the benefit has been real.

    What about CAD design software takes 32 GB? I was actually curious (I really didn't know why it consumes so much)

    From what I read the min is 8Gb but I would go for as much as possible. 16-32Gb would be best.

    Modern CAD software is generally 2D drawings from which you can create 3D models. Rendering these can use a hell of a lot of RAM to do this in a short timespan.

    CAD/CAM both can use up enormous resources, particularly when rendering

    Because I run up to three VMs at a time it is nice having 32 gigs of memory. . .

    I think 8GB RAM should be standard for all computers. Operating systems and programs today use more resources than ever.

    I ordered a workstation with 32GB RAM. I need it for CAD/CAM. It probably is enough but I may bump it to 64GB because why not?

    Having a bit extra ram never hurts. In 2013, i got 16GB of ram to help "future proof" it. With games edging up on 6+GB of ram usage I may have to double up to 32 or even 64GB of ram in 2-3 years lol, in that time they'll probably eat up 12GB or more of my ram.
