Been reading a bit, it seems that even 64gb is troublesome\unstable on this platform (also goes for AMD?)

I’d like to go higher than that in my next 3D\creator oriented build, 128 or even higher if possible (been seeing some BIOS updates that allegedly allow up to 196 or even 256gb on some boards?) so I can avoid threadripper build cost.

Is it a real issue and how would you go about building a max RAM-loaded workstation in 2023\2024?

Currently rocking ancient i7-5820k with 64gb ram and it feels a bit tight on the ram side when doing Houdini simulations and even some renders.

    You can use as many sticks/gb you want however it’s the frequency of those sticks is the only issue. If you get 5600 speed ram it should work no issues. Anything above that is going to depend on cpu lottery/motherboard

    You’re better off getting 2x48GB sticks for 96GB of RAM. You can OC those pretty well.

    I’m a 13900k owner running 4 sticks of ddr5. Only 64gb, so take it with a grain of salt for 128+.

    My experience is that 4 sticks and high capacities are absolutely stable… until you decide you want your RAM faster than JEDEC.

    I finally got my 4-sticks of DDR5 running stable at their rated 6000MT/s, but it was… a painful process. I learned more about RAM overclocking than I ever wanted to, and it involved manually adjusting voltage settings and multiple overnight MemTest passes.

    Theres some people running Micron B rev configs in either 2x32 or 4x16 which can still do 4300-4400 G1. 4xDR compatibility is also listed at 4400 on current DDR4 mobos.

    The problem is that ram went EOL like 3 years ago and you can only get it second hand now. I totally screwed up by not getting 4x16 when it went on EOL sale.

    This is actually a lot better for 128 Gb than 4800 DDR5 G2.

    i’m using 192gb across 4 sticks of ram on a z790 formula and the 14900k is not stable at all. Only reducing clock speed to 5.5ghz works .

      well that sucks… have you tried lowering RAM speed?

        yeah but it still crashes even with the lower ram speeds. The only thing that seems to work is reducing cpu clocks. Do you think this 14900k is faulty?

          no idea honestly but other guys in this thread seem to be able to run it with 4 sticks at lower speeds
