I think you can manually download the CUDA installer from nVidia’s website and that will update it to the latest version.

What are you using to text the card on mac? I just got the 470 and have yet to install it but do want to compare it to the 285 i currently have in there.

What might you guys suggest?
cheers

It could be that the 470 wont perform properly with os x power management.

I had to do the following to get full performance with the 470:

Go to System/Library/Extensions

Drag “AppleGraphicsPowerManagement.kext” onto desktop.

This will make a copy of it.

Throw out the original in the Extensions folder.

Restart

Yes i did delete the kext.

I had really decent 25 fps few days back before 10.7.3 update.
Today i did this update.
I just did put up test results ans they did not show the same numbers Sasha got.

This why i think something is wrong with cuda and / or setup generally.

I used CudaZ like on win.
Generally the same app that that has been mentioned here on the forum.

I will look into re installing separate cuda driver.

If any ideas please just shoot.

(OT:Also i made my own custom Y cable if enyone is interested i can put up picture of it.)

Sorry i did not realize CudaZ was for Mac as well!

do you have a download link possibly and any advise on best to use it and where to really focus one’s attention in comparing say a 285 against a 470?

thank you!

i would dig up the method Sasha did bring out some months ago was
“Standard Candle Test” if i’m correct.

Look here: https://forums.creativecow.net/thread/277/6760

There was number of nodes and number of blurs.

It should give you really good result that is comparable with other users with actual media and GPU.

The update will sometimes reinstall the KEXT. Did you re-remove it after the os update? Additionally I would do the KEXT power management modification steps as suggested to re-enable power management as the card will draw a significant amount of power constantly if not managed.

[Margus Voll]

” power management modification steps”

I’m not sure i know those steps.

Could you direct me ?
