It seems like with Exact Timing my VRAM Clock is still locked at 2100Mhz even with one screen On... with Automatic (PC) timing the VRAM Clock drop to some Mhz with one screen On).

On the right side, the 2560x1440 screen set on Manual with horizontal total set to 3600 and pixel clock that i have changed to 777.61 Mhz to match the 3440x1440.

Note that i've tested with automatic (PC) timing on the 3440x1440, this give a pixel clock of 799.90 Mhz, I tested to copy this setting to the 2560x1440 screen and the results are the same, black screen and nothing.

There's no way to make this work then. The monitors have to be synchronized to be able to change the memory clock. Normally this is done during the blanking periods to avoid garbling the screen contents, but if you have two monitors that aren't synchronized, then this is impossible without affecting one of the screens. You would be better off having two monitors with the same resolution.

Ok thanks for your help, at least we have tried !
