Problems with GTX 580s and 590s Tweet

[Refracty]

Hi,
I tried to use an older PC with one 580 and 3 x 590s installed and updated the Nvidia drivers.
I haven't used it for a while but I remember that the machine was very fast before even if it is an old-timer in terms of GPU age providing little VRam.
But with version 3.06 standalone the responsiveness while working in Octane (during changing materials or current time on the timeline) was very, very slow and the rendering stoped or slowed down after a few dozens of frames. The scene is very small and on other computers with newer cards (Pascal and Maxwell) its running smoothly as expected.
I also tried to open up a local ORBX and stored the files locally. No network rendering was involved.

Does somebody else experienced problems with oder 580s or 590s running with Octane 3.06+ ?

Refracty;

I am using (and have tested) many different combinations of GTX 570 2.5GB, GTX 580 3GB, and GTX 590 2x1.5GB cards in my (6) 2006-2012 Mac Pro dual Xeons w/ dual boot OSX/Windows... (I prefer blower style cards, and Macs Fan Control from Crystal Idea solves all heat issues)

Yes, they all work great in Octane 3 Standalone and ArchiCAD plug-in, coming in behind the 980 and above, slower than the 780 ti as well. They are generally faster than the 960, 950, 770, 760, 750ti, 680, 670, etc.
The GTX 590 is as fast as the Titan, 1060, and 690; and faster than a 970 and 780. Dual 580s are way faster than a reference 980...

I love my dual EVGA GTX 580 Classified Ultra 3GB setup in OSX especially, as the factory 900MHz OC w/ voltage bump really works the GPUs with no problems at all... Any factory OC'd GTX is great in OSX, just for the simplicity of the stable overclock.

That said, while Octane 3 is overall very good with the GTX 500 Fermi series, it has seemed to limit overclocking potential in Windows on my Mac Pro hardware. When testing with Octane 2, the GTX 590 w/ 20% OC was as fast as my reference GTX 980ti. Now w/ Octane 3, not so much...!

Free hardware is good, fast hardware is better! You can overcome some of the memory limitations of the Fermi era by reducing the number of parallel processes in the Render Kernel; this trick applies to 1060, 980, 970, 780 etc. cards running out of VRAM as well...!
Fermi is still fast!! Check out the Benchmarks: https://render.otoy.com/octanebench/res ... ingleGPU=1

(First experiment into Octane godlike territory. Very successful; always need to use a display connected to a GTX 500 series Fermi card in order to hard reset boot back into OSX from Windows. The EVGA GTX 570HD 2.5GB, the MSI GTX 580 Lightning Xtreme 3GB, all GTX 590 cards, and a few others support DisplayPort w/sound; these work great with the Apple LED 24” and 27” Cinema Displays, both in OSX and Windows) No mods beyond Velcro...

Nice Octane sleeper setup, even better w/ dual quad-cores. Best 1st-Gen Mac Pro setup I have seen; For a 12-year old machine, it runs Windows 7 Pro better and quieter than many current PC builds!) Very minor Dremel mods to plastic front fan shroud for pcie IO bays...

(First eGPU experiment; easy and troublefree. Current OSX builds can only boot w/ 4 GPUs so it would pay to get four of the fastest single GPU cards. Since all my CUBIX test cards were blower style, I disconnected the Expander’s internal fan for a much quieter experience, and ignored the hardware failure warnings. Wonderful Octane speed, easy, reliable!) No mods!

Runs Octane 3 for simple and blazing fast live presentations w/ class) Inverted HPATX layout, PSU on bottom. Gorgeous, but Mod City!!!
