P3041 SERDES voltage change

I am working with the P3041 We are using PCIe Gen 1 x 4 lanes. I would like to increase the amplitude of the transmitters, I did change the SERDES supply voltage (XVDD) from 1.5 to 1.8V and connected a 1.8V supply. I also strapped CPU_LAD[26] to GND. I did not see and increase in the amplitude, is there something to change in the RCW to force the transmitter to use the higher voltage?

 

Thanks
