Nvlink Verification

[dhanad]

Hi I have just setup 2xTitan RTX Nvlinked (shows as index GPU 0 and GPU 1), I have a 3rd GPU - a Titan Xp as GPU 2 in the index (Maya Output Window) when I run Arnold GPU 6.0.2. It shows Nvlink=1 against both the Titans. Is this a reliable way of confirming that they are truly linked. Or is there a better way to verify this.

Note: I have gone to the Nvidia Control Panel, and set the SLI option to "Maximize 3D Performance". I am attaching two images of what I am seeing.

Okay nevermind, I just verified using NVLinkTest program. Essentially changing the mode to TCC via command line and rebooting the system complete the process. Woot!
