OMEN by HP 40L Gaming Desktop PC GT21-0000a (514R7AV)

I bought new RAM. CORSAIR VENGEANCE LPX DDR4 RAM 32GB (2X16) 3600MHz CL18-22-22-42 1.35V (CMK32GX4M2D3600C18)  

after install i booted up the PC and spammed esc and went into the bios. I went into advanced tab and selected custom profile since xmp profile was greyed out and i couldn't change the parameters. When i click on save and exit a few seconds later while rebooting a message "The CMOS checksum is invalid. The CMOS will reset to the default configuration and the computer will restart. Afterwards, please check the BIOS setup options to see if they change." and it restart and once i sign in, i CTRL+shift+esc and click on performance and select the memory. It shows i now have 32 instead of 16, but the speed is still 2133mt/s and not 3600. 

What else can i try?
