Memory reached 2133 Mhz, 9900k MSI Z-390 Ace
I've encountered the same problem too. My friends' 470 Gigabyte Gaming Ultra is stuck at 2133Mhz, and we can't adjust it in BIOS or with Easy Tune. We managed to get it up to 3200Mhz once, but now it's not working anymore. It seems AMD isn't doing much, which is why I never had an AMD system for myself.
*shakes hands* However, I’m using an Intel CPU... It seems like the problem isn’t with the CPU.
Also I haven't used XMP before; I just set the frequency to my desired value, like 3200MHz. Unfortunately, I can't access the BIOS on my board since the latest model changed the interface to a simpler "Click BIOS" for the AM4 platform. At the end, you might try "Memory Try It!" to check if it works.
I reviewed the BIOS settings and observed the recommended memory timing from the "Timing-XMP" diagram. I adjusted the timing and voltage manually based on that profile, as detailed in "Manually Tweaked TIming." After restarting, CPU-Z still displayed the default timing values, as illustrated in "CPU-Z after BIOS tweak." It appears the changes I made to the BIOS memory timing had no impact. Meanwhile, my CPU adjustments did produce noticeable results. Could anyone provide some guidance? Thank you!
When you turn on XMP and save-and-exit, does the system restart several times before starting Windows? This might suggest instability in the CPU or motherboard using DDR4-3000 MHz. If you keep XMP settings but drastically lower the RAM speed—for example to DDR4-2666—will Windows still boot normally?
The system operates under Windows normally. I attempted various RAM frequencies, but the outcomes remained unchanged—Windows boots as expected, and CPU-Z readings stayed consistent at 2133. Despite these adjustments in BIOS, no modifications were detected.
Did you ever find a solution to this problem? Im having an identical issue identical board and I know of only one way to "force" XMP timings, it's break fix only - more on that below. At the end of the day I'm thinking this could very well be a motherboard problem and you should get your mobo RMAd. That's what Im going to do, because this Z390 ace is lacking in quality. Don't get me wrong, it has a great feature set. But to give you an idea: Mobo is nearly brand new. No more than 80 hours run time on it since it was taken out of the box in early 2020. -The digital code display in the upper corner fell apart. Literally. Which means, I'm severely limited in my troubleshooting or situational awareness, because you cant tell what sequence you are in during the boot process! -I lost primary PCIe slot randomly out of the blue. Just decided to **** the bed on me while it was still LIKE NEW. Consequently, I have to run my massive RX 5700 XT (Gaming X 8GB) on the secondary PCIe slot, which means the fans are really super close to the bottom of the case. Because if this problem, I can no longer game until I get my board RMAd. Which sucks because it love to be taking advantage of all that horsepower wrapped up in the 5700 XT package. Because the GPU is nearly touching the bottom of the case, it can't efficiently pull as much air through while gaming, as I said, this sucks. -The board has random times when it just decides to reboot itself on startup, out of the blue. Like Ill turn it on and then the display will lite up for about 2 seconds, then it goes blank and reboots again. Very annoying. I definitely would call myself an MSI "believer" but this is just beyond one simple little issue. As you can see, all these problems have happened to my system WITH A MOTHERBOARD THAT HAS NO MORE THAT TWO WEEKS RUNNING TIME ON IT! Now, on to the solution. Forgive the rant. To fix this you need to do a cold shutdown by pressing the CMOS reset button on the back of the motherboard to restore defaults. So hold the button down for about 4 seconds and eventually the rig will shut down, and fair warning, it will take all your BIOS settings with it, you've been warned! Next boot into the bios and immediately enable XMP don't touch any other setting until you reboot. Go back into the BIOS after first reboot and you should see the ram running at full speed now. Granted, this fix is a little sticky, but it's better than nothing. And dont expect to save it to a profile because that doesn't work either. So do XMP before anything else after a hard reset, okay? This is a little like trying to catch lightning in a bottle. ps try reseating your memory as well. if you have 4 slots try the other two. A 300$ motherboard, and this garbage to deal with? WOW MSI I'm blown away. Very good board from a feature perspective but quality control has gone to hell. At least with this board.
Could it be that you're using four dimms in a dual-channel setup? Certain motherboards restrict memory speed when this is done. It might be better to use just two sticks, one per channel. I'm checking if this will impact your motherboard and the extent of the effect.
