Hello guys,
thanks for kind comments !
Im visiting every week this forum as great people with lots of knowledge is registered on forum and active in posts, so I'm not hiding
Thats why i reactivate this topic to discuss this machine hardware and "why" is now faster then before.
The nature of my 3D projects is connected with "confidential" contracts as I'm working for Gasprom, JC Decaux, etc...
Thats why i can't post in Octane gallery my renders

and i don't have time for personal artworks
I will explane a bit more about my work on machine hardware and usage.
thermal paste
lots of comments for thermal paste have been made. I have to comment that as I'm monitoring temperatures from outside ( liquid cooling temp ) and via software. While rendering videos in Premier or 3D on CPU ( full load ) temps never get higher then 42C, which is great result. GPU thermal paste - also the same as above, rendering for 24-7, 10 days in a row temps never get higher then 39C to 44C. So thermal paste application is fine.
water cooling rig
readed a lot comments, text articles, blogs on the web how you never should leave your water cooling rig to work more then 24h because something can happened. What can happened ?

only more rendering to archive more work / money exploitation. On motherboard there is a protection which activates automatic shutdown if something fails. Its very easy to configurate that. Also, two D5 water pumps are in the system, if one fails, second will continue to work. Also, with two pumps, pressure in the system on pumps mechanics is less - smoother work.
PCIe 3.0
Thats what i want to discuss. On previous motherboard and processor seems while rendering that machine can't "breathe". While i was moving
mouse cursor, explorer or something else it was slow, very slow like everything will stop in a second. Now, projects are loading faster and everything works smooth as didn't before. Maybe the key problem was in CPU, maybe in PCIe speed, dunno... but I'm happy now
OCTANE benchmark
DIRECT LIGHTING - its funny as when i opened the same official benchmark scene on previous configuration, I've got result of 85-90 Ms/sec. You can see it in my video posted on youtube before one year. Now, after reconfiguration when i open it its 180 Ms/sec... whattt

really surprised ! Path tracing and PMC are faster for small values. Nothing big to mention
And at the end, here is the render I've did recently with previous config, which I'm able to publish on line.
This is all my product design. All of those products are manufactured for real.
Greetings,
Karlo
