I saw a huge improvement in smothness, loading times and stability when I went to 64GB. Definitely worth it for me.

 

 

@okletsgoOn a 7800X3D? I dont see your system specs?

Im not familiar with your 5900X, but that just doesnt seem right to me? (pagefile issue?) I never go really near maxing out my 32 gig ram on this older build, and all I do is multiplayer. But anywho, Im wondering how the 9800X3D is doing in DCS for Ram for dugite57's new build

Well you can reduce RAM usage by lowering your preload radius. I am also flying in VR (Reverb G2) and the Missions we run are pretty heavy on performance. The nice thing is that thanks to multithreading I get ~60fps at pretty high details on busy servers. On the other hand PvP focused servers with static ground targets like the PO WWII server take far less RAM (anywhere between 10GB to 36GB depending on how busy it is. The most obvious improvement going from 32GB to 64GB was that all stutters went away and loading times improved massively.

Which mobo and ram?

Does anyone know if win 11 is better for the 7800x3d than win 10? I know the game bar and core parking of win 11 is irrelevant for this chip but was interested in other aspects as well, pcie5 mngmt, storage transfer speeds, Ethernet drivers. I would prefer to stay w win 10

1) 1Which mobo:

On AM5 the choice between mobos is pretty much unimportant. On earlier generations AMDs mobo VRM layout and VRM cooling was insufficient. OEMs learned from past mistakes and for AM5 pretty much all of the mobo OEMs have well specified VRMs and have ample VRM cooling to the point that it makes no difference to normal users sort of competitive overclockers. You should choose mobos based on a) form factor for your case, b) feature set and c) price. For the vast majority of users B650 makes more sense than X670E unless you are trying to future proof your hardware. AM5 is guaranteed to be supported for one more CPU generation in 2024, but it is likely that it will also support a 3rd CPU refresh into 2026 also.

2) Which RAM:

This is something worth consideration IMO. Most users recommend 64GB system memory for DCS in order to enjoy stutter free campaigns and multiplayer. This is do-able with 2x32GB DDR5 sticks. I've read a report suggesting a decrease in performance going to higher memory on AM5 and for this reason I would avoid unless you have a specific work reason to need that much memory, independent of DCS. Given the choice of 64GB your best bet is 6000Mhz 30-40-40-96 or 32-38-38-96 2x32GB. Which sticks? Ideally chose base on "tested / qualified" SKUs by checking the support tab of the OEMs website for your mobo of choice. If your choice of memory is not specifically on the qualified list, you will still 99% of the time be okay, but I prefer going for one of the pre-tested options.

3) Win 10 vs 11:

I don't think it matters for performance, but personally speaking I always chose the older OS.

I did consider a gen5 m.2 but it's early days and the price is high heren in Australia.  Given the mobo has 4 x gen4 slots and 3 x gen5 and if there's a "need" I can add in the Gen5/s in a couple of years when they are mainstream. For me coming from the world of SATA 6 SSD's the gen4 will seem like a new world. Regarding the RAM, I just went for 64 as I'm not realy being cost consciuos and just want the best within reason. I also know DCS seems to love RAM. Going from 16 to 32 in the old rig was very noticable at the time.  My broad plan is to give it a refresh in 2025 with the 11800X3D 8ghz 16core or whatever they've got out as the last of this platform, gen5 may well be in that refresh and I guess a pcie5 GPU.  I've found over the years, and I've been simming since the 1980's 8086's, that you can never have enough ram or storage  I remeber memmaker,,,

Interesting. So if I'm reading this correctly, and it's early in the morning and I'm on my first coffee, the 7800X3D numbers are accurate. However, 7950X3D are not and should, in theory, be slightly higher due to core parking issues and higher speed and v+cache amount? 

Unfortunately, I didn't see them actually present the numbers for the 7950X3D, just theorizing based on slightly higher clock speed and a bit more v-cache. 

I got my 7800X3D yesterday, sitting in my desk, but I won't have time to tinker with it until later this week due to having to drain the loop to pull the CPU.

When I upgraded from 32GB to 64GB I was sporting a 5800x3D/4090. I am now using a 7950x3D with the same 4090, but with 64GB DDR5 6000MT/s CL30 RAM (2x32).

To elaborate a little, the improvement with 64GB was (almost?) completely on multiplayer only. I don't think there was much improvement in single player. The overall experience is just a little less clunky. Especially on the Syria map.

@okletsgoThanks for the clarification

You'll want to have Windows 11 if using DDR5 RAM too btw.

Really? I never heard that before. Does DDR5 not play well with Windows 10?

 

[Fakum]

OH BOY! That is a whole different topic! I was trying to do some research on Win 10 vs Win 11 for DCS yesterday, and for the most part, the consensus was to basically stick with Windows 10 for now.. And if going to Windows 11, do a fresh install instead of an upgrade. BUT, there was no mention about DDR5 memory use, so this is indeed an interesting point. I didnt even think that it mattered, so why?

Iam upgrading ..aswell  ... got ram comming ...64  and i plan to use win 10  so friday or next week iam up and running ..unless  f*uks ups ...or faulty stuff   *knock's on wood *

[Pappen]

There is nothing supporting that windows 11 should support DDR5 better than windows 10. @72Stu where did you get that information from?

[EightyDuce]

Not sure where the other person is getting information from, but I ran DDR5 on W10 for about 6 months before switching to W11 when I did a full rebuild. In those 6 months I didn't have any apparent issues. 

@72Stu could you elaborate on DDR5 and W10 vs. W11 compatibility or why you suggest running one over the other? 

[Chump]

I will be running DDR5 on Win10 next week as well (waiting for all the parts to arrive). We should have lots of feedback on real-world results.

[SilentSierra]

Win11 is stable enough to run everything. I don't know, why do I should avoid it?

[Fakum]

I think we should move on until @72Stu responds otherwise.

[Greekbull]

Had zero problems with Win 11 and my 7950X3D build that I've been running since the day after the 7950X3D launched...Can't see any reason to stay with Win 10...

This of any use? 4090 78003xd & MT

Sorry if already posted.

Edit: I read the OP comments and lowest FPS was 75 when there was a MLRS launch. The poster was able to bump their Varjo from high DPI to higher DPI and still had a smooth 80-90fps.

Quite interesting but very hard to see any detail. The 7800X3D performs well, but I wish there was some frametime information. At some point soon I'll be able to post my own tests but coming from a i9 9900KS there won't be much comparison....

Hello All,

Many apologies, I'm owning that post (one too many gins I think). 

Of course, DDR5 works just as well with W10 as W11. I think I meant Intel 12th gen works better with W11, as you all know.

Sorry for the confusion!

It seems that AMD 7950X3D + AMD RX 7900XTX making more FPS in Microsoft Flightsim than AMD 7950X3D + Nvidia RTX 4090 in this spezial CPU-GPU comparison-benchmark (PC Games Hardware 05/23).

So probably RX 7900XTX is the much more better choice for DCS World too???

Here in Brazil, AMD VGAs are like codfish head, nobody ever saw.

I would take that result with a pinch of salt.....it's easy to screw up benchmarks. I would look for more sources which make this claim. For example, Toms Hardware had the 4090 well ahead of the 7900XTX last December in DX11. But...AMDs drivers have improved a lot and MSFS does not seem to behave like all other titles, so it's hard to say.
