Hi Bro

Which cpu do you use? G.SKILL NEO IC b-die?

Can you tell me your setting voltage?

Thank you

 

Have try 3900X, 3950X & 3500X. The 3500X turned out have the best FCLK capability based on MSI. (Just need 1.1v for 1900 FCLK there), the other two need around 1.15v+. 😅

G.Skill Neo 3800c14 1.5v kit BDie.
The setting is just to attempt / replicate XMP setting with 1900 FCLK up & running, all auto. Then, passed the memtest, just like I pass with MSI Board.
At C8I vSOC Auto is at 1.1v when running at 1900 FCLK. But I've try up to 1.35v vSOC & messing with VDDG, like I said before.

Just have the workaround few days ago, Load XMP (DOCP) -> set FCLK 1900 -> minimize BCLK 1 step. BOOT, enter OS. Set back the BCLK to 100MHz.
All voltage are auto with this setting, vDIMM is 1.5v set by XMP. Memtest passed.
With another way, I can't POST / enter the OS like previously.

It's works somehow, but must have workaround for this simple requirement & can't just load XMP & set FCLK 1900, that passed flawlessly in the other board, on this WR maker board just bumped me out. 😅😆
Or just the silicon angel not at my side this time.. LoL

Thanks for the response. 😃

Just tryed 2101 bios from front page, actually that bios is really good, have much better consistency than retail 1302 & 2010 BIOS. Cant pass memtest with other bios, but with 2101 BIOS it works great!

Probably your XT doesn't like 1900 flck, try 1800 and work your way up

Hello

You Try SOC voltage from 1.05 to 1.1V

If that doesn't help, you can try 2010 Bios.

Thank you

Fan control on the CH7 makes me want to off myself, god damn what a cancerous board this is. That or ASSUS's awful software stack and very slow BIOS updates.

Other than that it's a solid board.

very slow bios updates? Well not sure if you checked ch8 page but there is a new bios every 2 weeks. However you have to remember that here on hwbot and in general overclockers couldn't are less about fan control, it is usually disabled with fan's at maximum speed possible :D
