Looks like a spoke to soon its already happening again

In preferences under editing it has memory limit I have this increased over the default which may not help in rendering but increases available memory for editing at least. I wish I could use my system memory and cuda together?

Go in to preferences and increase max memory based on your system. I have 32 gb ram plus the 4gb card i'm sure this helps my situation. Animation I'm rendering is not a huge scene either, but I'm not having issue since the reinstall of driver. Not sure if it will happen again when I do a scene with more vertices sounds like yours is much bigger if its saying out of memory.

It first took it back to .29 then yes required to update again to .036 in system settings cuda update.

Make sure your max prefences is as high as your memory. It seemed to have updated my cuda driver installer or something hopefully this continues to work I've been rendering all morning since update still running fine.

I am and was at 7.0.36 also however when I found that link it download and installed some tools and samples the cuda driver version didn't change yet it quit having the issue. After that install

This driver update seems to have fixed issue as it is not happening anymore crossing fingers.

Anyone find a solution yet?

It started doing it probably 3 months after buying it computer is only 1 year old I updated the cuda drivers if thats what you mean?
