Failed to initialize RAM at 2933 MHz frequency.
Failed to initialize RAM at 2933 MHz frequency.
I own two 8GB G.Skill Aegis DDR4 3000MHZ CL16 RAM modules. I activated the XMP profile in BIOS and configured it to run at 2933 MHz, but after saving the settings the computer immediately shut down. It entered a boot loop several times—3 to 5 cycles—and after a longer startup it finally began, though the displayed RAM speed automatically returned to 2133 MHz.
I don't have a platform setup. Could you clarify what you mean by "rest of your platform"? Are you referring to a specific device or system?
AMD Ryzen 5 2600 with AsRock B450M PRO4 Pro4 running Windows 11
Early Ryzen processors didn't consistently reach 2933 with every RAM configuration, though the 2600 model officially supports DDR4-2933. It's possible you're encountering an issue. Consider these adjustments: lower the frequency slightly, such as to DDR4-2800, and verify voltage levels—manually set the voltage to 1.35v as recommended by XMP settings. If that doesn't work, increase the voltage a bit, up to 1.4v, but avoid exceeding 1.5v. For the system controller, try 1.05v if supported, which can safely go up to around 1.1v, though stay within those limits.
On AMD's site they mention 'up to 2933,' but that's often a lower estimate. The 3600 and 5600 models show 'up to 3200' as their performance, which usually reflects the top speed due to the infinite fabric technology. Ryzen processors typically aim for a 1:1 relationship between clock and system time, so they often rely on XMP profiles. I’m not sure how the 2600 handles clock speeds, but 3000 and 5000 were popular choices around 1600MHz or 1800MHz, matching 3200MHz or 3600MHz configurations. I’d try the 2666MHz or 3200MHz unit and set its clock settings to auto or match the memory’s frequency. Technically, memory operates at half the advertised speed—around 3000MT/s—and it works at both high and low frequencies, so it effectively runs at double the stated frequency. In short, it’s running at 1500MHz but moving data at 3000MT/s because of the waveform behavior.
