NVIDIA Quadro K4200 Optix Error

Hi,

When I launch RenderMan in Maya, I am getting this error:

Denoiser failed:
[ERROR] Optix ERROR creating RTX context

I know this card is well dated now and it did work with denoising before. But now, I am not even trying to use the denoiser and it is giving this error all the time. Then when I try to use the denoiser, it doesn't work.

Does anyone have any tips on how to resolve it? Or even if this is not the correct place to post this, please point me in the right direction, thanks a lot.

According to Nvidia officials :

The NVIDIA Quadro K600 is a Kepler GPU based board which is not supported by OptiX anymore beginning with version 6.0.0. Only Maxwell and newer GPU architectures are supported since then.Means you’re limited to OptiX SDK 5.1.1 on your system configuration.

So basically you need to remove the one installed and download and install the 5.1.1 found in their legacy section here :
NVIDIA Developer Program Membership Required | NVIDIA Developer

But to note , you will have problems here and there while rendering on the 5.1.1 and Nvidia on the other hand recommends upgrading to a better GPU to overcome them sadly , so this is a case of Nvidia pulling the plug on these GPUs and is only a matter of time ...

Q - As I tried OptiX 5.1.1 on Quadro K600 but I think it is not able to render during the debug process.
A - Boards from GeForce RTX 2060 upwards to the highest end Quadro RTX 8000 (48 GB VRAM) today would be recommended for GPU ray tracing.

Thanks for the reply nIGHTmAYOR

Yeah, so I think the best bet would be to get au updated card. I had intended to do this but not just yet.

I was reading some stuff on these newer RTX ones, especially in the last few months with lots of tweets appearing in my feed. There is a lot of excitement about them and they seem really difficult to get a hold of, right?

Would you have any recommendations on which one to go for? I know there is quite a few options, but I wouldn't be too up to speed on graphics cards. I will eventually be looking into some GPU rendering too.

The RTX line of cards all share same architecture except for different speeds and ram capacity to suite every budget out there , the Quadro RTX line is more cores along with RTX architecture .

- Cards that read ##60 RTX this means it has enough speed and power to suite casual gamers
- Cards that read ##70 RTX this means it has enough speed and power to suite VR gamers enthusiasts
- Cards that read ##80 RTX this means the included all they could of speed and power to suite everybody (Developers Included)

On 2020 the Nvidia GPUs moved on from 2xxx series to 3xxx series , they did not claim to have added anything more to RTX capabilities but rather more speed , reviewers of these cards claimed the added speed was marginal in relation to the previous 2xxx line that does not justify why they were overpriced as such

So bottom line , more money = slight more speed along that line nothing else to note about troubles or change in architecture like one may doubt .

Thanks, I will need to have a think about which one to go for.

Also, would they be just plug and play kind of thing or would they be only suited to newer PC's? My PC is about 5 or 6 years old. It is a Dell Precision Tower 7910

Cards from different manufacturers have pre advertised power supply requirements , they often need higher Watts power supply units due to all the fans installed .

Also the majority of RTX line comes in double sized cards , meaning they will take space of 2 cards so your PC Case should be ready for such beasty line of cards .

Finally you should make sure the card you are buying is compatible with the provided GPU slot you have on your mother board which you haven't discussed what it is , 90% of the time it will as the slot architecture haven't changed in a decade but they are trying recently to .

P.S To note , I tried to research the layout of the Case of your Dell Precision Tower 7910 but all I could find were photos of the case from outside , and several photos of happy people , so you may need to provide several photos of the Case from outside and inside so to see if it has enough space for the card .

OK just at work now so when I get closer to upgrading I will check back here and try get some pics uploaded. Thanks for the help

Good luck. I've been surprised that not only the RTX 3000 series ("Ampere") cards have been nearly impossible to find at prices anywhere near MSRP, but the 2000 series ("Turing") cards are in a similar situation.

The GTX 1600 series ("Turing", but without the hardware raytracing capabilities) don't seem to be much better.

If you check the benchmarks for the RTX 3000 series, you'll find that they are not a trivial upgrade over the RTX 2000 series at similar prices. An RTX 3080 may not be a great upgrade over an RTX 2080 ti, but the 2080 ti had an MSRP of about $1kUS. The 3080 is a considerable upgrade over a 2080 or 2080 Super, which all had MSRPs close to $700.

MSRPs are mostly meaningless at the moment. The situation may endure until the second half of 2021.

Or, buy a card from a reseller (aka scalper) for maybe 1.5X MSRP.

In addition to the compatibility stuff already mentioned, make sure that your power supply has enough capacity and the right type and number of auxiliary PCI-E power connectors. The higher end RTX 3000 card are real power hogs. A non-overclocked RTX 3080 (according to eVGA) has a maximum power draw of 320W. For a 3090, 350W. eVGA suggests a minimum 750W power supply, with two 8 pin PCI-E auxilary power connectors.

Note: I just checked the specs on a Quadro K4200: 4GB of VRAM. It was launched in mid 2014 You might be happy with an RTX 3600, which has 8GB. The 3600 is also a lot more powereful than the K4200.

Thanks for the info!

Do you mean RTX 3060 Ti though?

Probably yes about the 3060 as there is no 3600 , as for Ti part the Ti means they used faster rams on that model marking that it will be marginally over all faster than one with similar chip without the Ti , yet both of course would be faster than your current card Ti or not .

Basically what he is trying to say is to wait for 2nd half of the year till prices drop and that even the entry level ##60 is considered a well worth of an upgrade verses a Quadro from 6 years .

I did not want to head there to suggest a budgeted upgrade as at the end of the day people working with rendering sometimes consider cutting edge upgrades to buy them time , so I still believe its all up to your budget but did hint you are not losing much on technology between models but just speed .
