MPG X570 GAMING EDGE WIFI + Thermaltake ddr4 4400mhz RGB

Hi guys any help would be good , i have the following

MPG X570 GAMING EDGE WIFI motherboard
4x 8gb Thermaltake ddr4 4400mhz RGB

the issue im having is the max stable speed i can get the memory running at is 4000mhz, if i change the settings to above 4000mhz the bios wont boot

timings suggest 19-25-25-45 1.45v

the motherboard has picked up on the timing profile but i have had to manually adjust voltage to 1.50v for this to work at 4000mhz ,

does anyone have any advise on getting this memory to run at its fill 4400mhz speed. are there any different timings or voltages to change?

 

Thanks in advance
