It depends on the game. Currently, I have a Ryzen 7 7800X3D, which I’m replacing today with a Ryzen 7 9800X3D. Ryzen 7 7800X3D will go to my son. I also have an MSI MAG X670E Tomahawk WIFI motherboard, which I’m swapping for an MSI MPG X870E Carbon WIFI and X670E Tomahawk WIFI will also go to my son. My setup includes an RTX 4090 and 64GB of RAM. You can probably guess how many average FPS I get in 2K resolution at ultra settings.

Hows the performance coming from an 7800X3D?
But if instead of making us guess it you tell us, we’ll do it quicker. 
So true, I believe.
Let’s be point blank: The majority of us simmers ( me at least) don’t bother about streaming apps, dev apps, photo/video editing at the same time.
The only programs I’m running while sim flying are little navmap, discord and track-ir.
I, for that reason alone,don’t feel the pressure to double my RAM from 32 to 64 GB

Ok, so as it is recommended to use 64GB RAM for MS2024, I decided to go >ahead and upgrade from my 32GB RAM.
Why don’t you just use a tool that shows you how much memory your flight simulator actually uses… I’ve only seen a maximum of 17 gigabytes so far…
I tried upgrading from 32 GB to 64 GB ( 4 sticks of 16gb Corsair vengeance) and SIM didn’t like it, several crashes so gave up and reverted back to 32gb with no further problems.
So I just updated my Lenovo Legion Pro 7i 16IRX8H from 32GB to 64GB (i9-13900HX). How do I see what the memory timings are? (Kingston Fury KF556S40IBK2-64 HF 33164T3T30000010520140012 9905789-147.A00GF) Haven’t tried FS yet.
sorry to hijack the topic, but how’s the temps with your Legion while running MSFS? does it Throttle?
I’m looking for a Legion Pro too to replace my old MSI Leopard

One way is to download a small utility called Zentimings. You won’t need to go into your bios and it will display a lot of info about you memory however it doesn’t allow you to change anything.
Edit: forgot to mention it’s only for AMD based PC/laptops. Otherwise your home screen in the bios or CPUZ utility will give you the memory timings.

I had 32GB Corsair Dominator Platinum DDR5 6000Mhz I bought another 32GB so I would of been using 4 DIMM Slots. My PC went nuts with 4 DIMMS installed. I finally worked out that the original RAM I had was single profile EXPO but the new RAM was Dual Intel/AMD profiles and they would just not work together at all, no matter what I did. I got all sorts of errors and no POST at all and yes all in the correct Channels I did not mix ram up in the A/B Channels, but i tried it anyway as nothing would work.
Corsair now make Dual Profile RAM and it is really hard to get single profile ram so be careful of that. I also got a new 64GB Corsair Dominator Platinum DDR5 6000Mhz Kit - Dual Profile
What is wild is the new 64GB & new 32GB sticks work together just fine for a total of 96GB and it all runs lovely together. I have however taken out the 32GB kit as I am not sure if using 4 DIMMS impacts performance, I cant really get any definitive answers I have not got time at the moment to dig into it. The 64 and 32 Kits are the same family now just different sizes. Exactly the same speeds etc.
My Systems is, in case anyone can answer is:
AMD 7900X3D
MSI MPG X670E CARBON WIFI
64GB Corsair Dominator Platinum DDR5 6000Mhz
ZOTAC NVIDIA 4080 OC
With 32GB, it did get very hot. I didn’t notice it to throttle, but, it may have, but I didn’t notice any performance loss in MSFS. I should keep an eye on that. I haven’t tried it yet with 64GB. I also just switched it to use only the RTX4090 (16GB) for graphics, I don’t know what affect that’s going to have, if any.
I have been editing some extremely heavy Blender files, and now that I think about it, it’s possible it was throttling there. But it feels way better now with those files with 64GB. In fact, I haven’t noticed it to even tax the system yet. I’ll keep an eye on it. I’m going to fly in MSFS tonight.

Thanks for sharing your experience with the 4 sticks of Corsair Vengeance. The crashes in MSFS is really concerning. I almost picked up the 2nd set of Ram today, but I will hold off until 2024 is released.
Was this 2 kits or 1 kit? It should work using 1 kit.
FS2020 does not like my 4 16 GB G.Skill 7200 MT/s DDR5 sticks
running at 7200 MT/s.
But they run fine at 6400 MT/s in FS2020.
They run fine at 7200 for everything else.
I have tested the following RAM modules:
-
G.SKILL 64GB (2x32GB) 6000 CL30 Trident Neo AMD RGB
F5-6000J3040G32GX2-TZ5NR -
G.SKILL 32GB (2x16GB) 6000 CL30 TZ5 Neo RGB
F5-6000J3038F16GX2-TZ5NR -
G.SKILL 64GB (2x32GB) 6000 CL30 Trident Z5 RGB
F5-6000J3040G32GX2-TZ5RK -
G.SKILL Trident Z5 RGB (2x16GB) 7200
F5-7200J3445G16GX2-TZ5RK
with a Ryzen 7 7800X3D CPU and MSI MAG X670E Tomahawk WIFI motherboard (CPU, motherboard and tweaked 2x16GB DDR5 @6200 CL28 RAM I gave to my son). All of the mentioned RAM kits worked well with the Ryzen 7 7800X3D CPU.
Currently, I am using a Ryzen 7 9800X3D with an MSI MPG X870E Carbon WIFI motherboard and G.SKILL 64GB (2x32GB) 6000MHz CL30 Trident Z5 RGB F5-6000J3040G32GX2-TZ5RK (which I overclocked to 6200MHz and tweaked the timings). So far, I have not encountered any issues with these memory modules and Ryzen 7 9800X3D CPU.
These RAM modules are theoretically designed for Intel systems, but they also work with Ryzen and the A-XMP profile, which is essentially the same as EXPO and XMP. I chose these RAM modules because they are compatible with both Ryzen and Intel CPUs, giving me flexibility in case I decide to switch to Intel CPUs in the future. If I had chosen memory specifically designed for AMD, I could face compatibility issues later on.
FYI, memory modules with “NEO” in the name are designed for AMD CPUs.

What did you tweak the timings to? Did you adjust voltage?
Thank you very much for this detailed answer 
As i dont see me switch to Intel in the next years, id prefer to go for an AMD “optimised” version, therefore i think i get a “NEO”.
Thanks for this, i was confused when i read somewhere about “AMD or Intel RAM”, this helps a ton.

You’re very welcome.
Nope mate.
Thanks! What values for the timings tweak did you go with? 
These are M-die modules, so if someone has A-die they might be able to achieve lower timings, for example, with tRFC 392/400.
Anyway, I am continuously testing and adjusting the timings - current settings are shown in the screenshot below.
FYI, I am really impressed with the new Ryzen 7 9800X3D and MSI MPG X870E Carbon WIFI, so I might stick with AMD for a longer period. Because of this, it’s quite possible that I will switch these memory modules to the NEO version designed specifically for AMD.
