Pc more ram or faster processor?rtx 3090

[Ninjaviper]

Hello,

 

Looking to improve my VR experience

At the moment I have the following pc:

Reverb g2v2

I5 11600k

Rtx3090

32 ram speeds 3200( dcs wont accept the xmp profile) so running at 2900.

I also a MP player (beginner)

Fps 35 to 60 on the ingame DCS counter.

Question:

Is it better to buy a 64gb set or the i7 11700?

Thanks in advance!

I Already search a lot of topics.

I assume you mean i7 13700? If so CPU.

DDR4 memory is pretty cheap now.

I got extra 32 GB DDR4 3600 for 110 Euros.

If you run DCS multi-threading, the processor will not make a huge difference.  Get more ram or save further for a 4080/4090 GPU, this will change your experience dramatically.

Does the change from 32 to 64GB RAM increase performance in general or just in specific cases in DCS?

I hope it make vr less stutter when In look left or right.

I have a 3090 with a Ryzen 7800X3d and 64 gigs of DDR5 6000 ram and the same reverb G2 version you have.

I still get stuttering/ghosting like crazy when looking out the side. Even with shadows all off. Motion reprojection helps a lot but doesn't fully remove it.

I moved this 3090 card from a 10 year old system with an x99 chipset and 64gb of DDR4 3200 and there is barely 10fps improvement on average for me.

In DCS VR, the GPU is by far the biggest upgrade if you have even a remotely capable CPU

RAM is either you have enough or you don't.  Lack of RAM will cause occasional stuttering as new assets are loaded from the disk drive on the fly.  I've seen 40GB+ in use playing on highly populated servers.

It will not increase FPS.

You're not going to gain in performance at high resolutions doubling your RAM, for the simple reason that DDR4 CPU controllers are limited to 4 ranks that they can manage, and there are no 16GB sticks with one rank, only 8GB sticks can have one rank, and not all of them does.

As a result, under load, your CPU will throttle down, even with B.Die and 3600MHzkits, in my case, tested back to back, the loss was <> 31%, same RAM only 16GB instead of 8GB sticks.

You're better off investing in a B.die RAM kit, corsair or GSkill, my choice would be G.SKILL TridentZ RGB Series 32GB (4 x 8GB) 288-Pin PC RAM DDR4 3200 (PC4 25600) Desktop Memory Model F4-3200C14Q-32GTZR

They are designed to be O.Ced so you easily can get 3600MHz from them, but do not purchase two different 16GB kits, you would risk incompatibility between them even in the same batch, they need to be tested together, 4 X 1 stick is safer.

Intel: Overclocking RAM.

It is often not really the case, the performance depends on the CPU controller, not the RAM kit itself, if you have 8GB or 16GB, of course you're short in capacity but 32GB of low latency RAM works faster with every DDR4 CPU, there is a point where more is less and it shows under load, we're talking  4K or even MT.
