I adjusted the RAM speed too high, and now the PC exceeds the post limit. The post lights are off, but it shows a black screen. I removed the CMOS battery for five minutes and kept holding the power button for ten seconds while the power cord was unplugged. This machine is a Cyber Power PC built with a Ryzen 7600 CPU and Radeon 7600 GPU on an ASUS motherboard, though I’m unsure of the exact model. I can’t access the BIOS to modify the XMP profile; all I see online suggests resetting the CMOS instead. Need assistance.

First I would power it on and let it run for 15-20 minutes. It's likely the system is trying to reset its memory. If that doesn't help, check the cables (HDMI/DP) or ports and connect directly to the motherboard. Sometimes resetting the BIOS restores the display to the GPU. If that fails, skip troubleshooting and remove the GPU, then connect the display straight to the board. Remove the RAM and CMOS again, then carefully reinstall one stick at a time until it boots. If it works, reinsert the other stick and install the GPU. If it still doesn't boot, recheck the CPU connections—sometimes you need to swap in a different CPU first before trying the GPU. This process can be tricky, especially with AM5 systems.

Additionally, the system needs some time to start up after changes to the RAM; it might even restart a few times on its own. Let it settle in. Also, which memory modules are you referring to? You've just adjusted the speed and left the voltage settings unchanged. What was the original frequency?
