3TITAN + 470 on X9DRX+-F = physx FAIL

Hi there

Well:

Problem is simple;

Physx options are missing on nv contorl panel. Yeah classical problem but !

Now here's the reason I don t undestand what i'm encountering:

I have just replaced the motherboard.

Old motherboard used: asus Z9PE D16:
2 titan wocking on 8x 3.0 and one on 16x 3.0 and the 470 worck on 1X 1.1
-one of titan had the 1st default GPU displaying.
-With hypersli patch for SLI (1.0) compatibility (and with 331.93 and 332.21), with or without hypersli, sli and physx worked.
-Whith this configuration, no issue, physx can be set on nv panel, 470 dedicated worked great ...

NOW

With supermicro X9DRX+-F
-with same windows 7, same drivers, same patch hyper sli 1.0 ...
-all titan and 470 worck on 8x3.0/2.0
-one of titan has the 1st default GPU displaying
-the SLI works fine , but physx option has totally disapeared on nv control panel.
-I have tested with beta driver, without SLI patch, on win serv 2008 r2 sp1 ...

I have never seen the physx option again ;(

WTF Huh

I m probably not eligible because of HW trick but why ?
Is it absolutely required to turn off the titan in 16X ?
Is it possible to constrain phyx activation in driver ?

HW:
If it may help:
