OTOY Forums

Hi everyone,

I have a Lenovo Thinkpad W530 with the Quadro K2000M card. First of all I'm not sure if the name Quadro K2000M is the same card with Quadro 2100M (??). I think it's the same. I'm telling that because when i first got my laptop, the graphic card in the Nvidia preferences had the name Quadro 2100M with 4.2 version of CUDA...

I was trying to render in Octane and i got a "(failed)" next to my cards name on the bottom right of the viewport. I noticed inside the preferences of Octane that it could read only 16 CUDA Cores from my card (but my card has 384 cores)...
Then I tried to update my drivers of the card but there where no updates available (including beta). So I was looking inside Nvidia and I found some updates for Quadro K2000M under "Beta & Legacy" menu and I installed them. Now I have CUDA version 5.0 (Octane can see that) but still Octane reads only 16 cores and the card says "failed" when i render...

Any ideas??... Thanks!

K designates the Quadro is based on the Kepler series. Unfortunately the Octane demo builds do not support the Kepler series yet, sorry.
Kepler architecture is somewhat different from previous generations and the Octane code has had to be adapted to accommodate the changes. Currently Kepler builds run ok but at about 2/3 speed in large part due to some hardware changes Nvidia made.
If you were a customer I would tell you to go back to the Quadro driver wiith cuda 4.2 and try the non optimised experimental Kepler builds of Octane. I notice though that there appears to be only one driver available currently at Nvidia for your card, the Quadro 305.93 and that this is cuda 5.0. Leveno may have their own driver you should use. As this is quite a recent card I guess they sold the laptop with a beta-like driver with cuda 4.2. Perhaps a driver with cuda 5.0 will be OK though. I guess you need to try it to find out.
I am not sure anyone has tried a Kepler Quadro card before either but most likely it will work fine.
The most recent win64 Kepler build is at the bottom of the Standalone beta 3.01 post in the Release Candidate Testing Forum but that is only available to licenced customers.
I guess you could buy but make some special arrangement with Otoy to get a refund if it didn't work in your case yet and you weren't satisfied to wait. Usually they dont give refunds but in fact almost everyone who has bought Octane is very happy with it.
It may be that with your laptop you are just a little ahead of the available drivers and Octane builds at this time but in the near future you won't have a problem.
Hope that helps.

ok thanks pixelrush!

Hi,
I've the same pb with à Dell M4700 with an Intel Hd 4000 and a Nvida K2000M configurable in an "Optimus" way...have you fid a workaround and have you a solution to run "Octane Render" on this kind f platform?

I've de-activate Optimus, to let my win7 booting only with the Nvidia graphic Card, but it don't runs better...

Thanks for your advice...

Which version of Octane are you trying to run and what exactly is the problem?

Running rc1 solved my issue on a Dell M4700 with a Nvidia K2000M graphic card.
