GPU Workstation Build

amd 9950x3d
asus tuf oc rtx 4090
Asus x870e crosshair hero
CL30 EKWB Dark CR-360 Nucleus AIO 360mm
Crucial P3 Plus 4TB SSD
Samsung ssd 870 evo 4tb
RAM ?????
Super Flower LeadEx VII 1300W PSU

So my big question is RAM and everything I've researched has told me that 192GB with 4 sticks is extremely unstable and you're forced to modify the timings to get it it to 5200 Mt/s to get it working and I'm not in the mood to do massive amounts of tweaking so I'm going to settle with 2x48GB for now and see how my archviz workload handles it. Primarily I'll be doing my rendering with the GPU and I'll eventually upgrade to a 5090 if and when I sell my mother to the cartels first.

I've been following Muhammed_Hamed's testing with his 5090 so I'm fairly up to speed what to expect. With that said, I'll be doing a ton of OOC rendering especially with my huge scenes so that's why i need to know if I should stick to 6000mt/s rated RAM or will I see any benefit going as high to the 8000mt/s. I also should add that I'll be overclocking the 9950x3d as it's shown to be pretty damn stable and efficient with the most modest PBO settings. But will I see any benefit with the memory speeds when loading and unloading 96 GB worth of data when rendering or should I just got with the basic 6000 mt/s and low latency chips? Also if there's any recommendations on cases I'd love to hear them as I'm still debating that and also which brand and/or modules you'd get based on my needs.

Thanks!

Hi S_K_I

192 GB with the 9950X at stock speeds is not bad at all, you will not lose any performance for rendering(CPU or GPU). It will affect gaming on the other hand slightly
Most of what I have seen were able to run 192 GB + 9950X at stock, stable. Very few people managed to adjust the memory to run at the rated frequency but honestly don't waste time on that
My advice is to go 192 GB, as many people got it to work already. Having a high-end board helps, which you already plan on buying. And picking a kit that is certified for AMD Ryzen, and in the Motherboard recommended memory list.
If it runs stable at stock, great! There is still a tiny chance you would have issues running 192 GB of memory at stock, then you will need to play around to get it to work but hopefully it works out of the box. Let us know how this goes.

For me personally, I bought 2x 5090s after selling my 2 cats to the cartels and the only board that could ever fit the GPUs at PCIe Gen 5 is the Asus ROG Strix Z890 Extreme at 1300 Euros. This is why I went Intel for the first time in 5 years
I paired it with Gskill TridentZ Royal 6000 Mhz 192 GB, worked fine at stock speeds if I turn off the integrated GPU in BIOS. Then I tried to play with memory timings to get a higher frequency, which didn't work well. I gave up and left it at stock

With that said, I'll be doing a ton of OOC rendering especially with my huge scenes so that's why i need to know if I should stick to 6000mt/s rated RAM or will I see any benefit going as high to the 8000mt/s. I also should add that I'll be overclocking the 9950x3d as it's shown to be pretty damn stable and efficient with the most modest PBO settings

More reason to go for 192 GB of system memory, if you go OOC with V-Ray GPU you need a lot of system memory. 96 GB of memory is barely enough to render scenes that take all of your 24 GB of VRAM without going OOC

Also if there's any recommendations on cases I'd love to hear them as I'm still debating that and also which brand and/or modules you'd get based on my needs.

I went with Asus ProArt P602, no RGB, quite big and has good airflow and radiator support. There is also the Lian Li 011 EVO XL(the big one) pretty good case as well

But will I see any benefit with the memory speeds when loading and unloading 96 GB worth of data when rendering or should I just got with the basic 6000 mt/s and low latency chips?

There is not a lot of choice anyway if you go 192 GB
Frequency doesn't affect rendering performance, low latency could improve things a tiny bit

On another note, a second mid-tier GPU to connect your monitors to, could help a lot so all your 24 GB of VRAM would be for GPU rendering. Something like an RTX 4060ti 16 GB or the cheapest 16 GB GPU that you could find. I would also go 1500 Watts or more if I plan on getting a 5090 in the future or having 2 GPUs

Awesome Muhammed, thanks for the input much appreciated brother.
