How do I know what sort of timings to aim for at 6000MT/s?

First off, to your other post using CPU-Z, for easier overview, you should give ZenTimings a try. Gives you a quick overview of what your timings are, speed, FCLK, UCLK and everything in between; https://zentimings.com/

My timings;

 

So for 6000MT/s you want FCLK at 2000, UCLK at 3000, then it's all divisible by 6000. Then as linked in this thread as well, a lot of people like to use Buildzoid's timing, which work really well with my Hynix kits and gives you a good boost;

 

If that's working, you can try fiddling a bit with your primary timings. Like I dropped my CL from 30 to 28.

I would argue that gives you the best RAM setup for the 7800X3D in terms of both performance and latency. As the HardwareUnboxed video also showed, their tuned settings had the absolute best performance.

exactly what I have experienced. And I have no doubt we will see posts like yours very soon. 

Swapped my 2 x 16 for 2 x32 today and completed all memtests and a 12 hour flight.  

So to your point, simply adding two more sticks of the exact same memory caused CTD's and hangs.   2 fresh 32gb sticks of the same memory and timings but only occupying 2 slots and no issues.  

Won't having lots of Vram like 24Gig of a 4090 be more important than having lots of system memory?

Goodness, that sounds expensive 💸

I had 32GB of DDR5 for my Intel build. It turned out that it wasn't compatible with my AM5 upgrade. So I needed to shell out for another set of 32GB DDR5. Which makes me reluctant to throw more money at RAM unless absolutely necessary. I'd rather have a holiday in Hawaii... Which btw is probably not that comparable to the price of 2x32 DDR5.

In terms of the curve optimizer, I've got -25 on CCD0 (the "cache" cores) but I had to disable the -10 CO on CCD1 ("frequency" cores) as I got instability (BSOD) issues when doing video editing. 

around £1000 so far , so yeah "word not allowed " expensive lol

just to had to the previous , ive got an RMA underway 🫰

I will wait to upgrade until it becomes clear how much Ram the game uses, Sebastian said he experience hiccups when he was recording at the same time, and as far as I understand, recording takes up a lot of RAM and it's not something I will use myself.

Unless devs start using 16k resolution textures with no LODs and majority of people are using 8k screens then no.. not really. RAM and VRAM are not interchangeable

I went to 64 yesterday and not sure if it is the fact I run AIGTC, ASFS, OI4FS, Aviaserver EFB, Simshaker, lossless scaling and spad.next in addition to MSFS but it definitely improved the MSFS experience on my box...  Less object popping, especially when panning.

Thanks for sharing.

With MSFS 2020, yes. But at a much higher cost.

With my Titan 12 GIG of Vram in NYC with SamScene NYC and payware airports loaded my Vram exceeds 11 GIG, but my system RAM reads about 27 gigs out of 32GB. I have to disable some payware airports to get bellow 10 GIGS of Vram. That's with a 1080P monitor. MSFS 2024 better be more efficient or we will need at a min 16 GIG of Vram. I've tested with DX11 & DX12.

Yikes! At 1080p those numbers seem rather high and is very disconcerting. FS2024 is juggling these resources around a fair bit so I'm definitely taking the wait and see stance.

11GB of VRAM at 1080p resolution in DX11 mode? I have enjoyed flying around very dense scenery areas (for example, London with IniBuilds EGLL, Burning Blue Design EGLF, LN Design EGLK, UK2000 EGLC, PilotPlus EGKB, and ORBx London VFR Landmarks and GB South) in my PMDG 737-600 without any obvious problems, and I have a 6GB GTX 980Ti. I do not have AI planes enabled, but how much extra VRAM do they use? In fact, I have displayed the AIG models as static aircraft at 100% without problems (and I have a huge number of AIG models and repaints installed).

Interestingly, just saw this video posted on Reddit. Uploaded just an hour ago, so perfect for the topic at hand;

Seems that also confirms that even in MSFS 2020, 64GB makes a difference. Lots of hitching in some of the scenes with 32GB.

Though it's curious that it's actually not using up the full 32GB, it's not even close to the limit and it's still causing lower performance and hitching. Wonder if there's a technical explanation for that, perhaps a bug that causes it to hit the page file unnecessarily or something?

and that's with a 15 aircraft setting in FSLTL injector.

That's incredible! You must be running your sim at low to medium settings. My important settings are at ultra. TOD from 50-300 with auto fps.

It depends on the airport & the AI traffic that you load. The FSLTL fleet has a higher Vram footprint than AIG. Some airports eat up Vram. A good example is Dreamflight KTEB. If you have it, test the Vram with and without the airport.

It's also the cumulative effect of all these airports and a major city. If the user enables everything it could lead to a slideshow or a CTD.

Ok, so I am not imagining things. 🙂 Also went to 2x32Gb yesterday and this morning's flight out of iniBuilds' EGLL with over 100 AI seemed smoother than usual. Running ASFS, LittleNavMap, Volanta, Spad.next, AIG, FSHUDv.2
