the 6 GTX580 beast watercooled

[ghiom3d]

Hello,

I'm happy to show you the last update of my RT GPU beast.
6x GTX580 watercooled build with some Cubix base.




When my cards are running at full charge for hours, before the temps are around 90°C, now the temps are around 65°C !
I will save life time of this powerfull CG cards

Very cool, what brand is the water cooling?

[ghiom3d]

waterblock for CPU are from EK
the pomps are laing dcc+1
liquid is Feser VSC
and radiators are thermochil

Good grief!!!!!

how is your loop arranged? i see two pipes connecting each card.. not knowing the blocks connection layout it looks like the water can easily bypass each block by running straight down the right hand channel..?

[ghiom3d]

My loop is parallel , following the idea from EK waterblock manufacturer.
the water is splitted inside the waterblock and the way to the next.
the idea is to keep the flow speed .

the serial loop that we see most of time is easiest to setup and cheaper, but create some more resistance to the flow and isn't well optimised for pump .

I have think that the most complicated but the most optimised is beter for 3D rendering.
maybe serial is good for gaming, but after hours in serial, i see high temp in the second cards, more hight on the 3th and more on 4th ..

with parallel, the temps are nearly equal even if the first card is always the cooler .

May I ask what you are using this system for? As RT is not a production renderer, there are obvious limitations to what it can do. I assume this setup is stonkingly fast, but what are you using all that speed for? What kind of projects?

10 years ago the renderers are more limitted too than today and very very slow.
And 10 years ago we are already able to done very beautifull pictures with 3D renderers.

Yes VrayRT is production ready, and i've done a very beautifull photorealistic movie adv for new Chaumet Watchs collection .
Blend manterial is missing , displacement too an some others features . But somes years ago, we trying to not using all features that slow down rendering process and we use a lot of cheating.

With VRAY RT, i haven't use a lot of cheating like before. i've just focusing on what make my render beautifull and realistic.
With RT, light are unbiased like reflections and refractions.

So, the way was to make a very HD good mesh.
Then i have playing with lights and materials colors, bump , colors reflections, colors refraction to make the model very beautifull and realistic.
to finish and having a better render with RT GPU, i have used the VRAYCAM DOF and BOKEY that add much more photorealism when correctly setup .

the rendertimes are increadibly fast . From less than 1minutes to 3 minutes per HD frames. With VrayCam DOF and BOKEY !
i have create also some scene state to render some hand made passes. all materials are changed to vray lights materials with differents colors to do some ID passes with the same DOF .

I can't show you pictures from the movie before September .. but thrust me, VRAYRT GPU is production ready .

I guess it would be useful to see some of the beautiful renders you refer to. I partially agree with what you are saying, but part of the skill/art with architectural/design visualisation is working with what you've got.

What I meant with 'production ready' was the ability to produce 4k+ images with elements/passes/masks/many high-poly trees and bushes etc. With RT, from what I've seen, you are limited with what you can through at it.

Like I say though, I am completely prepared to be stunned by the images you have/are creating. Heck - if I like what I see, I might even by a 9xGFX card monster machine.

we aren't work on same type of productions.
I'm making advertisment of luxe and design and some jingles and opentitles. our requerys aren't the same
RT GPU is able to render many many polygons for my type of productions.
about textures i 'm not use a lot of bitmap .
About passes and mask, when your renderer is able to render in 3 seconds a frame with black and white or colored light material on black background, it's not a big deal to create a scene state wich change all your scenes materials to lightmaterials and send it to backburner or with Batch render.

I would like to show you my RT GPU render, i would like to show this to Vlado too !
But my client is asking to me to not show anything before september because they keep the watches secret before the show event they working on.

I've also done some print render at 5000x3500 300dpi for 20minutes and no noise at all with a lot of DOF and bokey .
