Hi everyone.
I'm attempting to increase the clock speed of my Vengeance LPX with 16GB RAM to 2933mhz, but when I check back into the BIOS it reverts to the default 2133. It's a bit confusing since I'm new to this process. Any advice would be appreciated. Thanks!

Assuming you're using that clock by just applying the XMP profile is step one.
This tends to be typical for Ryzen systems, unfortunately.
Reaching RAM speeds above 2400 can be unpredictable.
Try adjusting it to 2666 and check if it works; if not, you might be able to set it to 2400 but not higher.
If the setting doesn't hold, your motherboard may not be able to match the speed you're targeting, so it will revert to its default to boot.
Make sure you're using the latest BIOS for your card as well.
The number of DIMMs also plays a role—having two DIMMs usually gives a better chance of achieving higher speeds than four.
You can often find more information by searching online.

I don't have specific details about your system configuration. Could you provide more information or clarify what you're asking about?

Applying the clock using just the XMP profile is step one.
Further, this tends to be a typical issue with Ryzen systems. Achieving RAM speeds above 2400 can be unpredictable.
Manually adjusting to 2666 and checking stability might work, or you may find success setting it at 2400 only.
If the setting doesn’t stay consistent, your motherboard may default to its standard speed to ensure proper booting.
Make sure you’re using the most recent BIOS for your card.
The number of DIMMs also plays a role—having two DIMMs usually offers a higher chance of reaching higher speeds compared to four.
Often people search online for their motherboard’s memory experiences and find others’ results.

Assuming you're using that clock by just applying the XMP profile is step one.
After that, this tends to be a typical issue with Ryzen systems.
Reaching RAM speeds above 2400 can be unpredictable.
You might want to try setting it to 2666 and check if it stabilizes.
If it doesn’t hold, you may need to set it to 2400, though no higher.
If the setting isn’t working, it could mean your motherboard can’t support the speed you’re trying so it reverts to default for booting.
Make sure you’re using the latest BIOS for your card.
It also depends on how many DIMMs you have—having two is usually more likely to achieve higher speeds than four.
You can look up other users’ experiences online about memory performance on your board.
I tried XMP and experimented with various timings and voltages, but none succeeded. I’ll test lower speeds next.
Thanks for the advice!
