MSFS forums claiming 64GB of Ram helps on 3090s

Recommended Posts

Don't forget most RAM is in pairs and having two sets of pairs is not as good as having one pair. So 64GB in one pair (2x32) is preferred over 64GB in two pairs (4x16) as it's easier to meet the ram specs with one pair. Using two pairs will usually affect how fast you can set up your RAM, often requiring you to set it less than it's rated for in order for the system, to be stable.

That depends on the cpu and system architecture. Thats no longer a hard and fast rule.

Really curious to see how or if RAM speed(s) affects things beyond the amount of RAM installed

So glad I built my rig with 64GB of RAM. I had a feeling things like this would happen. I went the extra mile for the benefit of having that piece of mind.

Going from 16GB to 32GB of ram and using the XMP overclock definitely improved my MSFS performance.

MSFS is definitely the fastest loading sim I've ever experienced also, my setup loads both main menu and flight in under a minute each.

Not sure about 64GB though....this will be quite interesting to see.

How do I accelerate the time? I’ve never used the function before. 

Look for decrease/increase sim rate and bind a key combination:

Depends a lot on whether you are Intel or AMD. The AMD processors are knobbled by slower ram and shine with fast ram.   Intel processors sort of do not really care that much.

LOL, 3090 owner, I went from 32gb DDR4 3200 to 64gb DDR4 3600...... and got lower FPS over London and 2020 uses exactly the same amount of CPU mem (15/64) and VRAM (8/24)

sounds like a bios setting difference or something going on with the new RAM, no one should see performance reduction from increasing system memory, just doesnt make sense.

I can agree that you don't need 64GB RAM........right now...hehehe

When I say lower, its marginal

Re BIOS- nope- its running the XMP profile @3600 , I have read before more memory means more work for the CPU

I think the most ram I have seen being used was 22Gigs and that's with settings on ultra, so 32 should be fine.

I think some of you are missing the point here. Quoted from a very well respected developer:-

The 3090 ships with 24GB VRAM and if you fill it with buffer data or textures, you’ll certainly also duplicate a large amount of the VRAM buffers in RAM, and there you are: with 32GB RAM you probably really don’t have enough room to fit both the buffer data copy in RAM and the game working set!

 

 Even though your memory might be sitting at 70 or 80% it has a huge windows page file going causing “Limited by main thread”

I am not convinced that the "large amount" mentioned here adds up to anything significant. What exactly needs to be accessed that would force the game working set out of RAM... this all sounds like vaporware to me.. but am also interested in hearing your great results after adding another 32 GB to your system 😉

Well using VR I have seen my 3090 up to 20GB of VRAM usage, so I am too also interested in the results. Its due to ship tomorrow, so no harm in trying and if it turns out to be beneficial, then it helps others too.
