I'm having an issue with my RAM not reaching its advertised speed. I have ADATA XPG GAMMIX D35 RAM, and I've set the XMP profile in the BIOS, but it still shows running at 2133 MHz in Task Manager and about 1068 MHz in CPU-Z. My setup includes a Core i5 12400F and an ASRock B760M Pro RS/D4 motherboard. I want to know if there's a way to make it run at the full 3600 MHz, or if I should settle for a lower frequency like 3200 MHz instead. Any advice on what to check or adjust would be great!

It's really important to make sure you're saving the BIOS changes. If your RAM defaults back to 2133 MHz after booting, it could mean that the motherboard or the CPU's memory controller isn't handling it well. Consider updating the BIOS for better memory compatibility. You can also try increasing the DRAM voltage by a small amount, around 0.05 to 0.10 volts, to help the memory overclock stick.
Just so you know, CPU-Z shows half the MHz of what the RAM is actually running at – that’s normal. If XMP isn’t activating, ensure your modules are in the correct slots, and check for any BIOS updates.
Just a heads up, your CPU officially supports DDR4 speeds up to 3200 MHz. So, I recommend enabling XMP to set it automatically, then manually change the DRAM frequency to 3200 MHz first. If that works, you could cautiously try to increase it to higher speeds after.
First, double-check your RAM is installed in the correct slots, which should be the 2nd and 4th slots on your motherboard. Also, make sure there aren't any alternate XMP profiles available; some motherboards have different profiles for different speeds. Lastly, don't forget to save and exit the BIOS after making changes!
You could also try disabling XMP and manually setting the RAM values yourself. It might give you more control to get it working at higher speeds.
