Dear all,
Made some tests with the version that displays "version 1 beta 3.00" into the about box.
Amazing features with instancing. Would like to share with you some results but unable to do it cause never succeed finish a render.
But I was not able to finish any render, all crashed (all the PC frozen, had to switch power off to restart).
I updated to last Cuda drivers (301.42), but still the same.
It does not crash after any specifi action. Start rendering, and long time after (many minutes our hours), all is stopped, even the mouse doesn't move any more.
Just to let you know, if anybody encountered the same pb and have some ideas...
PS : autosave feature (for exemple each 5 minutes) would be very useful to keep at leat the last render !!!
Config :
Win 7 64 bits
2x GE Force GTX 570

Hi Pascal, this might be a heat or power issue.
Do you have any way to monitor the temperature of your GPU's and have you checked you have a power supply that has enough wattage for your system?
Another thing to test is rendering with one card at a time. This will test to see if one of the cards is causing the problem - or if both work ok by themselves then at least you know it is a problem only when both are used which could indicate power or heat as well.
Cheers
Chris.

Hi Chris,
I will try with only one card and let you know.
But did not encounter the problem with 2.58e version, even with huge files run for more than 12 hours with PMC at 64000 fps.
One card has a specific power supply (separated from the PC power).
heat pretty high (between 90° and 95°C), but not more than before this version...
Will do more tests.

Hi,
Thanks for the info. It would be very useful to confirm that the exact same scene that you can render for hours with 2.58e will crash on 3.00 (assuming the temperatures during both renderings are the same).
This will prove there is something happening with specifically 3.00. Unfortunately it would mean that you need to spend hours rendering to test
As you say 90-95 is very high. If i were you i would consider additional cooling if possible. These temps are definitely pushing the designed limits. The nvidia website states the maximum is 97 deg C for the 570.
Cheers

I can confirm this issue.
My Gigabyte gtx580 1.5GB Ultradurable sometimes freezes randomly with 3ds max plugin 3.00b for no apparent reason. Temperatures are well below 75C, interestingly underclocking gtx580 from stock clock of 795Mhz -> 730Mhz solved the issue.
I have also gtx460 in my system which can run anything i throw on it. I have tested both cards separately and togather. This is not scene specific issue. Only gtx580 has problem.

H petergazo,
I think ppoublan's problem is with the standalone 3.00 version - not 3ds max plugin.
If underclocking your card fixed the problem then your problem was not likely to be an issue with the octane build - it will be a problem with that specific graphics card as you say.
Having said that, ppoublan - perhaps underclocking your cards is worth a try for you as a test and also to reduce heat output?
Cheers
Chris.

Hi Chris,
I made some more tests while monitoring the temperature, rendering different scenes with one or 2 cards and with simple or multiple meshes.
Did not get any problem with 2cards+only one mesh in the scene or one card and any scene with multiple meshes.
You seems to be right, one of my card is crashing when becoming too hot (it even go over 100°C some times).
It looks like use of multiple instances and multiple meshes stresses more the cards and the temp get higher.
Unfortunately with my current PC I do not have any place to add cooler or give more fresh air to the cards.
I have to look at another tour.
Any case, support of instances is a incredible amazing feature.
Please, please, please, implement a good Sketchup exporter that support it with SU components
Here is a quick test with SU, impossible to do without instances (too long to export and SU cant handle so huge file without instances)
Yours
Pascal

There are a few options that don't involve adding more fans inside your case:
1) If your motherboard has more than 2 PCIe slots then you can put the GPU's in 1 and 3 to separate them.
2) try to lower the ambient temperature. Sometimes removing the cases side panel works (although not ideal i can't deny that this works!).
3) underclock the cards.
4) If you don't remove the side panel then make sure the airflow inside the case is good. You can tweak this by changing the direction of case fans.
What you need to do will depend on exactly what kind of case you have and the location of the fans but generally i find most cases are designed to suck air in the front and exhaust it out the back.
5) if you want to spend the money and the CPU cooler is pushing out a lot of warm air into the case then watercooling the CPU will mean that the CPU heat will get directly exhausted from the case leaving more cool air for the GPU's. CPU watercooling kits are relatively easy to install if your handy with PC's and are not as expensive as they once were.
Nice render by the way. Instancing is definitely a necessity for Archvis and greenery!
