Regarding the rendering with RTX 2080Ti, I use my GPUs for rendering mainly with some occasional gaming and benching
What I can confirm, in Octane RTX 2080Ti would be unstable beyond 2055MHz,usually I use in rendering 2025MHz OC profile which is rock stable, tried several renderers like V-RAY Next, Redshift, Blender Cycles or DAZ3D IRAY etc where anything above 2055MHz would crash rendering or result in TDR, tried several drivers, I thought so its driver issue, my RTX 2080Ti temperatures are below 40's in rendering usually sits in 36-38°C as other GPU
What is more strange my other GPUs are running same OC(GTX1080Ti with 2113MHz OC, GTX1080 with 2164MHz and GTX1080 with 2100MHz OC) from day one and if I render or use these cards in rendering no issues with crashing or TDR, previously I used two PSU setup(Seasonic 1250w and Corsair RM750W) and I thought its PSU, due this I went with Superflower 2000W PSU(bought from a friend)
Water temperature will have impact on overall temperatures and if you have space for 420mm radiator I would add it, you will have lower water delta T for sure, my loop have 4*360mm radiators plus MO-ra3 360mm and my water delta T in rendering is in 3-5°C as max with fans spinning at 900RPM as max(that's on MO-ra3 360mm), other fans are spinning at 750-800RPM
Particle simulation,personally don't use a lot particle simulation, if I do then I use Houdini, what software or plugin are you using for particle sims?
Hope this helps
I have messed a bit OCing for GPU rendering, but not much of a speed difference (a few seconds difference) and it's been recommended to leave GPUs stock when rendering to avoid any instability issues, at least from Redshift support. Currently only own Redshift, haven't used the others at length, I am loving the speed increase from my 1080tis, I can play with SSS materials without waiting 20 minutes or faking it in some way. I am currently using Real Flow plugin for C4D and haven't really noticed much difference when turning on GPU in settings. I've use it in the past and may push to get a full version instead of the plugin as it offers more in the stand-alone engine including more gpu support with their Hybrido engine. I am getting back into Houdini as well, but no time to train yet. A friend has been showing off what he's already accomplished with it's dynamics capabilities, so it is next on my list once I have the time. I've been doing more mograph than VFX these days, so I keep pushing it aside. I also have FumeFX on the list, but also needs time to train and learn. I'm done with Maya, have been for years, so I am looking at Houdini for my VFX replacement.
I am probably going to get the third radiator, but am wondering if one D5 pump is enough for efficient water flow across all components with this addition so I may add a second pump, but for now I will enjoy what I currently have. Are you running more than one pump for your setup? I think my first mistake was getting the HWL GTRs originally as they are most efficient at higher RPMs. I've spent enough (too much) cash on this build for now! Maybe after a few more projects, I'll budget it in as it will also require some down time. Thanks for chiming in.
