Bought Nvidia 285-Resolve crash

[Martin Widerberg]

Just bought and installed Nvidia GTX 285 in slot 1. Nvidia 120 in slot 2.
Didn't install any additional drivers besides the CUDA update Resolve did for the 120 a couple of weeks ago.

Fan is loud on the 285 from computer start. Everything runs fine. 20fps on 4K material. Resolve crash. Restart. Resolve now tells me that the 120 is used for image processing and it's not happy. Nor am I:)

Before installing the 285, Resolve was working slow, but fine.

CUDA Driver version 4.0.50
GPU Driver Version: 7.12.9 270.05.10f03

MacPro Nehelem

Have I done something wrong? Bad card? Any ideas? Thankful for any input.

Sounds like a bad card. Did you get a real 285 Mac edition, or is this one with a hacked/flashed EFI?

[Martin Widerberg]

Well, the seller claimed it is a Mac edition, but under the circumstances, I'm not so sure.
How do I find out if it's the real thing?

The real cards have 1024MB ram. Sounds like a bad card.

How do I know how to pick the right card?
Could you please advise me on that?

Thanks

My advice is not to screw around ... get a Quadro 4000 Mac Edition from PNY.

Its more expensive, but I find its vastly more reliable in most systems. To my work, its easily worth the full purchase price of these cards to have a half day of downtime.

Also, while the card is about the same speed as the now old GTX285, its expanded RAM lets it hold up better for some applications.

Its widely available for ~$755.

Thank you for the good advice Alexander.

I went for the 285 in the belief it would be the fastest for Resolve, but with ten different 285 on eBay all claiming to be the Mac version, it seems difficult.

Thanks

There are benefits to getting the Quadro 4000.

If you want a GTX285, the safest place is from macvidcards on Ebay.

You can find proper Mac 285s other places, but you have to know what to look for to make sure it is a true Mac 285. People hack non-Mac 285s to work on Mac and some even hack the 260 and 275 to look like a 285. I think you have a hacked 260 or 275. If they don't do the firmware right, there will be problems. Macvidcards hacks a lot of cards for Mac and seems to always do it right. And he is honest in telling you if he is selling a 260 or 275 hacked.

I bought a GTX 285 from macvidcards on ebay. It has 1792Mb Ram. It works. Getting about 10fps on quarter res.
