Problems with DDR4 RAM performance in Windows 11
Problems with DDR4 RAM performance in Windows 11
It seems you're trying to figure out if your current performance is optimal or if adjustments are needed. You might want to check the settings and see if any tweaks can help improve speed.
I installed RAM at 2800Mhz and activated the motherboard's memory testing feature.
Typically just enable XMP, but 4000 MT/s isn't optimal since the CPU's internal clock usually can't reach that. It will then operate in a 1:2 configuration (half the memory clock speed). Performance tends to improve to around 3600 MT/s, staying at full speed. If XMP fails, you might need to manually adjust it to that rate, though this requires more testing and patience. However, I suspect your performance problems aren't due to slow RAM. The HWiNFO data shows memory speed at 1333 MHz, which equals about 2666 MT/s (Windows lists it as 2666 MHz). Which Windows version are you using? Recent updates should display MT/s correctly. Memory timing appears elevated (CL 20). Would you like to check CPU-Z for the XMP profile listed in the SPD section? But it seems your system might be resisting full-speed operation. The BIOS version you have is likely outdated; updating to 7C56v1J could help compatibility. https://www.msi.com/Motherboard/MPG-B550...US/support
I aim for 3200 CL16 equivalent. 3600 CL18 or CL16 would be ideal, though AM4 may be unstable at 3600 speed RAM.
I propose using the 4000Mhz xmp/docp profile. Adjust the frequency to 3600, set the clock frequency to 1800, and keep voltage settings auto-managed by the chip. It’s likely the device will operate successfully if it supports those parameters, allowing future tuning of voltages or timing as needed.
Your computer is not showing any output and the CPU indicator is on. The RAM speed might be too high for your processor. You should lower it or check your system settings.
Restart the BIOS by accessing the JBAT1 pins near the PCI_E3 connector. Power down the PC by holding the power button until it stops, then turn off the PSU or unplug it completely. Wait a moment to confirm no power remains, briefly connect a screwdriver to the pins for a short duration, then reconnect and power up. Usually I avoid disconnecting the PSU but taking precautions helps prevent additional issues.
