64gb vs 32gb RAM

Featured Replies

I don't regret having 64 of ram. It makes my flight sim more study. With all my side programs running, my usage climb to 60% at times. 32 is okay but you will it a wall.

    32 is fine. I ran 32 for ages. I have 64 GB now, but I would never buy at today's prices .. it made sense when I bought it. I really don't think you need more than 32 GB.. 16 GB would be a little low.

  • Me, too.  Love a dedicated computer.

  • In my opinion, I would never "recommend" 64 gb.  32 is fine, 64 is what I would call a luxury.  It can help with 1% lows and a few fringe performance cases but for almost all situations 32 is fine. 

With my lowly AM4 motherboard, 64GB cost me about $110. I bought when the msfs2024 specs first came out which sort of scared everyone into getting 64GB.

RAM for an AM5 motherboard was and still is very much more expensive. Those 2 different motherboards can't use the same spec ram. What works on one won't work on the other.

Microsoft recommends 32 GB

my test configuration:

MSFS 2024 Beta SU5,

EGLL, runway 27R, A320 Neo

AI Traffic Ultra, other settings on ULTRA - HIGH

no other programs running

4 tests, same situation, varying memory load from 18 - 36 GB.

96 GB is unnecessary overkill

very nice.

32 GB. And with the current RAM prices, it will stay there for a long time😢

NVMe prices now will skyrocket, like RAM and GPU's did?

Not sure what made prices to increase the way they are now. But I'm glad I purchased my memory when I did. At these prices I hope I won't have to buy or replace any components any time soon. What a rip off for consumers.

^ Was $120 in Nov. '23. I bought one 4TB stick for $197 at Amazon at about the same time, September '23.

thanks everyone for your comments, much appreciated!

64GB has proven to be a nice-to-have, not a must-have for me.

I put 64GB into my last two builds (AMD 7800X3D and 9800X3D), which I did because it was inexpensive at the time, and it seemed like a good idea for future-proofing things.

I have seen DCS exceed 32GB when loaded-up, and occasionally MSFS has nudged above the 32GB mark, but I'm 99% sure that it only does that because it's available, where it would just page out some of the stale VM with little to no noticeable operational impact in a system with 32GB memory.  I've never had a system RAM related issue running P3D, XPlane 11/12, or MSFS on my 32GB-configured 13900KS + 4090.

Were I to need to build a new machine now, I'd go with 32GB without a second thought.

96GB here ... two 48GB modules ... I've used over 32GB during flights with my add-ons.  Microsoft Official "ideal specs" are 64GB RAM

Per MSFS Official Zen Desk link here.

Understand your concern ... RAM is ridiculously expensive right now.

 

 

Extraordinary claims require extraordinary evidence. - Carl Sagan

When I had 32GB, I always closed all my programs that weren't sim related. With 64GB I can be lazy and leave my dozens upon dozens of browser tabs open.

I did a rudimentary test in 2020 when I upgraded from 32 to 64GB, and the faster memory speed is what actually gave me an additional 1-2 FPS, not the extra 32GB of memory. If you add an additional 32GB instead of buying a whole new 64GB kit, you may actually lose that tiny bit of performance if the new modules don't play nicely with your existing memory and your system lowers the timings of all the memory as a result. Rated memory speeds are only guaranteed when the memory is from the same kit... even if you buy identical memory, you're playing the "silicon lottery" by mixing different kits.

As others mentioned, the sim will take advantage of over 32GB of RAM, but whether or not there is a noticeable performance benefit would require a lot of testing that I don't believe anyone has taken the time to do.

I bought during a low point. But another reason my 64 GB Ram cost me $120 and 4TB ssd cost me $197 was Tom's Hardware. Everyday they search for best prices.
