3dsmax 2009 + 2010 | Windows 7-64 bit issues

[hunsuklee]

Hi all,

 

I'm having an issue with 3dsmax 2009 and 2010 not recognizing 4 of my render cores. I have a Dell T7400 (dual quad core) which was recently upgraded from windows xp 32-bit to windows 7 64-bit os.

 

For some reason, after the upgrade, I can only see 4 cores in the render frame window. Both versions of max with vray/mental ray are only showing 4, so I'm thinking the problem has to do with the recognition of the chipset or mobo drivers..

 

I think i've downloaded and installed every driver and patch on the Dell, Autodesk, and Microsoft websites.. I've also tried to run 3dsmax in Vista-64 bit mode and was unsuccessful Any suggestions? Has anyone else come across the same issue?

 

Appreciate the help!

I remember one time having the same problem.

try typing this in the max script.

renderers.current.system_numThreads=8

where "8" number of cores you want to use.

 

make sure the both cpus are recognised in the device manager.

Hey Lucky,

 

I've been having a similar problem with my computer at work. The box is 64-bit windows 7 with 3dsmax 2010 using mental ray. The computer was fine and rendering with all four cores until I installed the latest hotfixes.. after that it only displayed two.. but when I tried out your script.. it told me that it was not supported by mental ray. Is there a different script or work around for this particular situation?

 

Thanks again,
