Hi Everyone!
I have an issue with my ram memory with My x399 Taichi. 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. I have 1.30 Bios Version and I am really scared about upgrade it Cry
any Idea? 

thank you so much.

Don't be scared about updating the bios, download the latest beta bios for Taichi X399 which is 1.91E and use the Instant Flash option in bios, just follow the instructions and use a USB stick formatted to Fat32.


Get the Ryzen dram calculator and use it to work out the values to set your ram at if XMP fails.


Do a little research, it's not all that hard really.

You need to understand that you \r BIOS/UEFI is... ancient.... and the memory compatibility was increased at least twice in different updates including the latest (big) one -- I fully agree with lowdog.
Get on the 1.91E bandwagon like... now :)

I agree to update the bios but being as you are skittish about doing so I would recommend version 2.0 and not a Beta like 1.91E.  Not that 1.91E does not seem to be safe but it is a beta.

KarlMarx ---first try the flashback with the BIOS E1.91
Believe me that this BIOS even in Beta is stable enough for my rigs 24x7 operation.
This BIOS introduces newest AGESA and newest improvements into the mem-compatibility.
With careful tuning (use Ryzen DRAM calculator -- this is a must) 2400 can be reachable.

P.S. Please also note that 2400 is already above the specification so you should not wonder if it won't.

P.S.2 This is not only an issue with ASRock but general problem with TR and 8 sticks -- no matter if ASUS ASRock or others.

dont forget to reset bios BACK TO DEFAULT before flashing
and also seeing as your having ram issues just flash it with one stick inserted

this reduces the chances of corruption by 7x

Actually flashback is a low level feature comparable to EEPROM programming, that doesn't depend on RAM or CPU lol...
Plus not necessary to reset to defaults - like I've said - low-level, overwrites all.
That is why if you do flashback you don't need a bridge bios :)
