  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

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
10.7.2
6 GB memory


Styrkretsmodell: NVIDIA GeForce GTX 285
Typ: Grafikprocessor
Buss: PCIe
Kortplats: Slot-1
PCIe-bandbredd: x16
VRAM (totalt): 896 MB
Tillverkare: NVIDIA (0x10de)
Enhets-ID: 0x05e3
Revisions-ID: 0x00a1
ROM-revision: 3434


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

Thanks
Martin
 
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
Martin
 
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.

That sounds slow ... what is the rest of your system? You are using the GTX285 as a second "Resolve" card right?

Is that performance at the end of a node tree, or just a single node/primaries only?

I think I get faster than that with software only using one node on 4K R1 materials with software only decoding without CUDA.

UPDATE: Just checked.

The system I checked on is a 6GB RAM 8 Core 2010 Mac Pro using just an Apple stock ATI 5770 1GB.

My test is a single node with just primaries.

With Epic 5K footage, and decoding set to 16 bits per channel:

I get 12 fps at half res, good decoding.

I get 18fps at quarter res, good.

Epic footage is real-time with 2 nodes throwing everything you can at them in Resolve Lite with a Quadro 4000. I never tried to push a Quadro 4000 to its limits in the real Resolve.
 
Just ordered a 285 from macvidcards. Could't resist the line in the Resolve recommended hardware text about it being the fastest:)
Thank you all for the good advise and recommendations.

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?

That's a PC version GTX 260 or 275 reflashed to appear as a GTX 285.

A real Mac GTX 285 looks like this:

I've seen a few sellers on eBay selling both, listing a GTX 260 saying it's a GTX 285, and also listing a real GTX 285 saying it's an "authentic GTX 285" that is "not reflashed, it's a true Mac edition" so you have to be careful.
 
Thank you Stephen

I will try to get a refund from the seller. You learn something new every day:) At Reduser
This is a really good forum. Thanks!
 
Martin,

Stephen Strangeways has all the info in his post above. There are a lot of shady sellers out there doing this -- they're picking up no-name generic GTX26x and GTX27x for $60 and flashing them with the Mac GTX285 EFI and then re-selling them for quite a bit more. So the cards typically work alright for GUI tasks / general use. Typically have a shorter lifespan... Will often crash hard, even burn up and die, if pushed with any real GPU processing or CUDA tasks. I would try to get your money back. The auction site should be able to help you as well.. After all, the guy completely lied to you.

The ones from Macvidcards are the only flashed cards I would trust, even then only half as far as I could throw one. The guy does know what he's doing, is an active macrumors.com forum member. He tweaks and even writes EFI code for the cards himself. I'm not really endorsing any of his flashed cards, personally I still think they're best suited for personal or hobby use.

The Quadro 4000 is the best choice for the Mac Pro at the moment. With the latest drivers, it's a touch faster than the GTX285. If you shop around and time certain rebates, you can pick one up for around $600. Sometimes less than that if you can find a used one. A big advantage to the Quadro 4000 is it is a single-width card and only requires one 6-pin power connector. This lets you easily use two of them in a Mac Pro for Resolve, and can make it more convenient in external enclosures, like the Cubix Xpander with 4 single-wide slots.

GTX285 is two generations old, about to become 3 generations out. It was discontinued some time ago. Best deal I've seen on one, especially for the Mac edition, has been from EVGA themselves. They occasionally have refurbished cards for sale on their site for around $250. It might be USA only and I don't know if they have any right now, but it's worth watching for. Seriously though, I would recommend the Quadro 4000 if you can. Just be sure to get a Mac version.
 
Thank you Jeff
I already ordered a 285 from Macvidcards, but your arguments for the 4000 are very convincing.
In retrospect, I would have been better off, asking those questions before buying the first card.
But I learned new things, and knowledge is good.

Could you recommend what output card I should use for viewing on a Pioneer plasma?
I keep reading Decklink Extreme, but what about DeckLink 4K?

Thanks
Martin
 
Decklink HD Extreme 3D+

With the Pioneer plasma, you obviously won't get to use the 3D functionality, but otherwise it's proving to be a great card and is fully supported by Resolve and other apps like Premiere. The Decklink 4K only makes sense if you're going to be monitoring in 4K. And it lacks some of the other bells and whistles found on the HD card.

You can feed your Pioneer plasma a 10bit HDMI signal right from the Decklink HD Extreme 3D card.
 
Also, if you're using a flashed card, you might have to delete the applegraphicspowermanagement.kext (I think that's the one) to get full performance. If you buy from Macvidcards, contact him and he'll help out, even make a tweak to your kext file so you can replace it. Worked like a charm when my gtx480 from him didn't seem to be working above 10 fps, now I get 14 nodes at full 24fps at half res premium (with rocket card).

Thank you Jeff

Tim, I will definetly follow your advice and contact Macvidcards about the kext file.
Thank you!
