is 3200mhz RAM that much better than 2666mhz?


Recommended Posts

Well of course it's faster but Linus says the improvement is not that great maybe a couple of % if anything depending on the software your running.

 

 

For me I'd go 32GB at 2666 rather then 16GB @ 3200. :thumbup:

 

YMMV

For most its not worth it. A few FPS. If your trying to get every frame out of VR or a triple screen 4K setup then maybe, but even then its a lot of cash for very little.

 

I'm currently building a new system myself and I'm struggling to justify the 4266 Ram. The bonus I see to the higher Mhz in testing (not mine but reviews) is that the low end numbers are higher. So you may only get a few extra FPS on the top end but the bottom end will be say 5-10 FPS higher than 3200.

 

Its a head scratcher.

If you are using Ryzen, up to 3200MHz makes a fairly significant difference due to the way Ryzen is built

Ryzen 7 5800X3D / Asus Crosshair VI Hero X370 / Corsair H110i / Sapphire Nitro+ 6800XT / 32Gb G.Skill TridentZ 3200 / Samsung 980 Pro M.2 / Virpil Warbrd base + VFX and TM grips / Virpil CM3 Throttle / Saitek Pro Combat pedals / Reverb G2

Also, I can't find the link right now, but in VR it can make a difference. There is an A/B youtube video that shows the difference with faster RAM. If you google for it, I'm sure you can find it.

 

 

For 2D monitor game play with sufficiently good HW, it probably won't make a huge difference (unlike in VR)

32GB @ 3200MHz is a good compromise.

 

 

The faster you buy them the harder it may be getting them to work properly.

 

 

Check the QVL and if possible, buy a kit mentioned in QVL to be sure it works as intended.

For Ryzen build, yes it makes a difference. Also using two slots only combined with high mhz is the best combination.

16 Gb vs 32 Gb

 

 

I would get stutters on the Caucasus map when I had 16 Gb. Persian Gulf over the cities would freeze for ten seconds before the sim would shut down to desktop.

 

 

Switched to 32 Gb and the sim never drops below 60 fps which is all I need and it never crashes now. Smooth as butter now...

From 2400 to 4000 you can gain about 10-12fps or so depending on the game if I recall correctly. Your average will be higher. I tried going for 2666 to 3600 and there was a noticeable performance increase but if you are not doing VR I don't think its worth it. I got mine mainly cause I lacked a few fps in x plane to stay above 45 fps and it worked for that. I could also set my settings higher. But I sent it back cause I found out I could set texture quality to high performance in nvidia settings and gain it there instead. People say 3200 is the sweetspot though

That's the sweets pot price wise, also ryzen 1000 generally had difficulty going above that anyway, however 2000 series can go as high as 3533, some even got 3600,so it's a question of how much money is optimal for you. Right now , some people are settling at 3400 cl14 and the gains stop at 3800mhz.This should take in consideration that the cpu can be swaped on any AM4 for future processors that could go even higher both on supported speeds and desirable bandwidth if they increase maximum cores from 8 to 12 or 16 like some rumors are indicating.

3200 CL14 or 3600 CL16 is a sweetspot, 3600 CL15 is the golden shot imho.

 

 

be warned there are hardly any to no 32GB kits that fulfill this that made it into any QVL. 3600 starts at CL17 with 4 modules and with 3200 CL14 I am not sure, havent checked but I assume it will be hard to find a QVL Kit with that tight latency across 4 modules 32GB total. ( checked, they are indeed available at 14-14-14-34 from Gskill, 4 x8GB Kit(s) and in Asus QVL )

 

 

if you ai m for ultra tight latency and MHz, do NOT take 4 modules.

The kits beyond 3600/3800 are usually 16GB or even 8GB kits only, TWO modules. Not without a reason.

 

 

We already have more cores than our bandwidth can feed. VMware shows this pretty well, or any other software where you load and offload huge chunks of RAM.

OP didn't state CPU, GPU, or most importantly motherboard. It depends. The most current motherboards from major manufacturers will keep updated BIOS and updated XMP profiles for faster RAM modules that come out over time. My current build has gotten faster and more stable since I first built it last fall.

 

If I turn off my XMP overclock profile I get stuttering. If I turn on my XMP profile stuttering goes away. I've never tried to measure FPS drops or benchmarks, or change settings to mitigate, but it's obvious by the smoothness and the frame rate counter.

 

Since RAM prices are starting to return to normal, can't really go wrong with 32GB. But RAM usage varies a lot from module to module, map to map, single player to multiplayer, background apps, mods, etc. I have no issues with 16GB but I don't usually play online in big scenarios. When I bought my RAM last year, RAM was very expensive and no 2 module 32GB kit was the speed I was looking for. Fast high end DDR4 has dropped in price significantly but is definitely in the category of high end diminishing returns. You're paying a high price for only a few frames per second. Best bang for buck is in the graphics card. With DCS and with most games in general this is true. Only a few major games released in the past couple years efficiently use more than four cores of CPU and fast RAM is pricey. Even a 2080 Ti is a better performance to price benefit than super fast expensive CPU's and super fast expensive RAM.

With higher mhz ratings come higher latency. Honestly, higher clocked ram is only beneficial to those who do extreme overclocking ,and even I wouldnt touch ram much higher than 3200mhz.

 

 

 

Maybe if I were to push it a little higher, make me a hybrid water/refrigerator loop and water cool my NB, GPU and CPU...and crank up the voltage a tad bit more...the extra mhz that ram runs will aid in stability. If you want fast ram, get 3200mhz DDR4 that can run in quad channel like what I use.

Thanks for all your answers, I'll probably go for 32gb 3200mhz then.

 

Just be sure to check the XMP/RAM Module(s) are listed in the compatibility list for your chosen motherboard. :thumbup:
