Pink screen RAM OC setting
Pink screen RAM OC setting
Hello, I've been attempting to push the 2x8 Vengeance LPX 2666 Micron B-die (CMK16GX4M2Z2666C16) to higher speeds on a B550M Pro with BIOS 4 and 4650G. So far, nothing works. I've updated the BIOS, used XMP settings between 1.35-1.40V, manually adjusted timings with a calculator, tested clock speeds from 2800 to 3200. The system boots but always displays the same error image after loading. When I try higher speeds, it shows a pink/blurry screen and requires a CMOS reset. Even the lowest stable settings cause this issue. I'm unsure what's causing it, but I've read about memory artifacts and unstable behavior—no case matches my setup. Everything seems fine on stock, but I'm not sure what to do next.
The problem occurs when using the integrated GPU. Consider using a dedicated graphics card instead.
Thanks for the feedback. It seems you're trying to avoid using a GPU, but it's working well with OCed RAM on your Ryzen APUs. Double-check your setup to ensure everything is correctly installed and configured.
No mistakes made. It handles 2667mhz, but past that point it stops working. Both my Athlon and yours behave the same.
Ryzen 5 4650G Pro benchmark results with optimized settings (GPU 2250MHz, RAM 4400MHz, I/O 2200MHz) from a professional channel.
