X399 taichi ram and XMP problems

[simonecammilleri]

Hi Everyone!
I have two issues with my ram memory with My x399 Taichi.
1)The RAM memories (Corsair Vengeance LPX 64 GB 8X8 2400mhz) are stuck to 2133mhz, so I tried to activate XMP profile at 2400mhz but when I select it the pc won't boot and I need to clear cmos.
2) I updated the bios to the latest version cause with previous versions Windows recognize all the 64 gb but allow me "to use" just 29 gb. Now Bios and Windows recognize me only 32 gb (But windows allow me "to use" all of these 32) Damn. I think this sticks are not totally compatible with this motherboard,also if in the memory list there are listed as compatible. Any Idea? Thank you so much.


BIOS 3.30


P.S Forgive me for my bad english

Hi Calvin, Yes exactly this:CMK64GX4M8A2400C14 Anyway I just looked better at the compatibility list but unfortunately I found that are not in the list, or better only the 32 version are. The funny thing is that I won the entire bundle (Cpu,Ram and Motherboard) so I won uncompatible things
