Ram stuck at 2133mhz with ROG-STRIX-B350-F-GAMING nad Ryzen 7 1800x

My new setup is ROG-STRIX-B350-F-GAMING motherboard with Ryzen 7 1800x CPU and 4x 8GB Corsair 16GB (2x8GB) Vengeance LPX Black, DDR4 3000MHz, 1.35V, CL15.

But the RAM is stuck in 2133mhz whatever I do. If I try to manualy change DRAMs frequency or overclock it then the pc just wont start so I am stuck with 2133mhz frequency.

Is there a trick to get ram frequency up? Even 2800mhz would do, but I paid for 3000mhz ram so I want more than 2133mhz and I beleave that so do others. Bios is the latest from Asus website.

  1. Did you try DOCP 3000 setting ? It should set everything automatically. It should run at 2933MHz. If you manually change frequency you have to also manually set all values including RAM voltage.

  2. Update you bios and try again. The launch bioses stink on many boards the newer ones are much better with memory settings.

    As mentioned above I'd enable docp, then manual switch to 2933 speed at first. Also ensure your ram is in the slots your board wants them in per the manual.

    Yes I did, and now I am able to run Ram at 2800mhz. But if I try to use 2933mhz then the system crashes.

  6. If I change it to 2933mhz the system crashes. I have 8GB Corsair in every of the 4 slots so they cant be the wrong ones.

  7. Oh.. 2800 is as fast as you'll ever get 4 sticks to run

    Is 4 sticks at 2800mhz better than 2 sticks at 3000mhz?

  9. Depends on the application. Gaming you'd see more benefit from a fast 16 gb than a slower 32. Some video stuff the 32 might with
