"Distribute memory across devices" not working

Hi guys.
After looong search I have to ask question about “Distribute memory across devices” option.
I got 2x RTX 2070 Super connected via NvLink. Motherboard that supports SLI. SLI turned on in nvidia panel and finally “Distribute memory across devices” checked in Blender. But im not getting 16GB of VRAM in blender (v 3.1.2), it only show 8GB.

I did test from this link:

Everything seems fine. Only thing is that my NvLink bridge is not lighting up green like on every video that I saw.

Anyone have expierence with similiar issue?
