Ram upgrade

hey all, i saw somebody here upgrading ram and having big results…
i planned to do the same a time ago
so, i m having acer predator PO3 600 intel i5 12 gb ram, gtx 1050 ti, and monitor 3440*1440 34"…a bit slow for now, all settins in low and rendre scale 100…but too much stuttering especially on landings
i m plannig to upgrade with a 16GB ram (wich is compatible with my system, i checked)…2666/DDR4/PC4
i guess i will see a difference ? even with my slow gpu ?
thanks for advice…

On one machine I went from 16 to 32gb. There was no difference whatsoever. None.

I guess where the difference comes is in the 8-16gb range. Having said that on my main machine it’s 16gb and ram usage rarely goes above 7gb for me.

Maybe I’m not too fussed about settings but I can happily run several other programs with the sim running acceptably too.

Same here. RAM usage increased, but that’s the only change. (Wasn’t unexpected)

Well, cannot advice you, just tell what my experience was.
I own a pretty high end PC (Intel Core i9-10900K, z490-e gaming mobo, Asus Radeon R6900XT)
and added 16 Gb of Ram to the existing 16Gb 3 days ago.
Running Eyefinity setup with all settings in the flightsim at ultra, res @7810x1440.
The sim is definitely GPU limited
For monitoring I use MSI afterburner.
With 16Gb of Ram installed, RAM usage regulary approache 16Gb (During startup or flight)
Made my first flight yesterday with 32Gb Ram installed
From EGMC to EIDW, 1000ft above ground in Justflight’s Piper Arrow in really bad weather (hardly VMC conditions😋)
After the sim started up MSI afterburner showed 22 Gb of RAM usage, changing during flight. At EIDW there was 17 Gb of RAM usage.
I cannot give you hard facts, but the feeling is that the sim runs smoother with 32Gb RAM installed.

In the Q and A yesterday they showed off a video where they went from 27gb of RAM to 14gb of RAM when flying over NYC with the next SIM update.
So no need to go any higher than 16gb.

Seems like a good progress, but …
What about additional programs in the flightsim such as FSUIPC, Pushback Express, Navigraph?
Not a dev here, but do not they use additional resources?
And what about when you run additional programs in parrallel to your flightsim?
After all windows is designed for multitasking🙄

If you never fly in photogrammetry areas, 16GB is enough. More is very nice to have in photogrammetry areas or around large custom complex airports.

Regardless, probably wise to wait for SU5 and see how you do then, since there are memory optimizations coming in.

We are talking here about RAM , and not Vram ?

I actually went from 32gb to 64gb 4x16gb 3200mhz as wanted to see for myself, I actually found less stutters and gained a few fps and was able to increase the lod sliders from 100 to 200 and had the same or better performance and fps i had before upgrade. Using 4 at 80 render scale i have seen as high as 29gb in the most demanding areas.

I was surprised myself as expected no difference but wanted to see for myself.

As said the ram usage is looking to be lower after next sim update anyway.

all will depend on what settings you run, my usage does not go over 10 gigs ever,
and that with the dc 6.

It is also possible to use ramcache which allows you to use as much ram as you want is possible to use 50+gb’s if you wish, but I didn’t see a difference when using that so stopped.

I was too. I have 32GB of RAM in my system, and when flying over heavy photogrammetry (London, Paris), my RAM fills up to 27-28GB.

Well, I do hope that in cases where the sim is GPU limited , there will also be a benefit (in terms of framerates) through the memory optimizations implemented in the next SIM Update.

smoother is the correct word… users allways forget the amount of pagefile which is used with less than 32GIG RAM and which slow-down the system. But we spoke so often in forum about the effect in case increase RAM and what is recommended RAM size. What we know is, that users with 16GIG RAM and a “wrong” pagefile setting run into out-of-mem. The app needs overall system memory of 32GIG ( of course depends on game settings, resolution, etc )…

Update: I forget to mention… I read somewhat about that the up-coming version is less demanding… but who knows…

Just makes me wonder how the sim handles those scenarios where PC’s with only 16 Gb of RAM are flying over heavy photogrammetry areas. Does it load data in another way? Does windows start swapping data to the HDD/SSD? Maybe it is better to make a RAMDisk for swapping data, or copying the whole flightsim directory to memory :thinking:, so everything runs within RAM​:grin:
As I understand it a ramcache is an intermediar between RAM and HDD/SSD that caches most used files, so the next time a program needs access to it, it does not have to read it from HDD/SSD.
But then I could be wrong

yep… check the commited memory in e.g. resource manager.

And Caching “things” into RAM does windows itself… in case you own more RAM, you get more cache.
Example: 45Gig in cache

During the great stutter plague of a few updates ago I upgraded from 32Gb to 64Gb and my stutters showed immediate improvement.

I think some of this issue was at least resolved for all other users with a more recent update but at the time and with whatever the issue was in the code at the time the extra memory did seem to help.

I could have saved myself some cash if I had just waited for the update though.

Thanks for the clarification
Makes me wonder what the use is then of ramcache

there exists tools which can use parts from RAM like a drive and ( important ) which is backed up to a real drive ( shutdown the PC ). On it you can copy files or e.g. place the msfs cache and you have a drive with RAM speed. But in my experiance you get no beneffit from this tools ( in contrast to old DOS ages and 25MB hard-discs :wink: ).

Depends on the time when you bought the upgrade.
With current hardware prices skyrocketing and the upcoming code optimizations maybe it is time to sell half of your RAM​:yum:and earn some money :sunglasses:. Enough for an additional addon?
