XMP Issues
XMP Issues
Hello, I'm facing problems with overclocking my RAM using A-XMP. When I set it to 3600mhz, it adjusts to whatever the DRAM frequency is configured to be. Although I chose DRAM frequency to auto, it still runs at 2133 mhz. My system has Corsair RGB pro 3600mhz and an MSI B450 Tomahawk MAX motherboard. Thanks, everyone.
CPUz, the utility
You might need to adjust timings to achieve a stable 3600. Although the BIOS says '3600', it could be failing to properly train memory during POST and then falls back to a slower default setting. You can attempt to manually configure primary timings and voltage (found on your DIMM package) and also adjust the speed settings. Changing advanced timings will require familiarity with the DRAM Calculator tool.
ADDED: MSI BIOS also includes a 'try-it' feature offering somewhat flexible timing options for different clocks. Even if you can't reach 3600, a lower setting like 3200 might suffice. 3600 isn't guaranteed every time.
The description outlines how XMP should adjust to the RAM's preset settings, but using AUTO mode forces it to operate at standard DDR4 frequencies, typically 2133 or 2400. What is the issue or goal here?
Sometimes beginning with fresh BIOS configurations is beneficial. This can be achieved via a CMOS reset or by loading the default settings in the BIOS save and restarting the system. After resetting the CMOS, navigate to the A-XMP settings and choose profile 1 or profile 2 before rebooting. It might encounter boot issues; setting the DIMM voltage manually to the correct value from the package can assist. If that doesn’t resolve the problem, consider using a higher DIMM voltage. DDR4 remains stable up to 1.5V, but avoid exceeding 1.40 unless testing is necessary. Be aware that a 3600 MHz frequency isn't guaranteed, even with Ryzen 3000 CPUs which are more powerful, as they are still rated up to 3200 MHz. Adjusting advanced timings—such as entering Expert overclocking mode in the BIOS—may be required. For guidance, refer to 1Usmus' "DRAM Calculator" tool to determine appropriate timing settings based on your components.
I performed this action, but it caused my RAM to reach 2133 MHz.
my xmp appears to align with whatever my dram frequency is, yet it doesn't stabilize at 3600mhz. Previously, i could set it to 3600mhz using xmp, but after unplugging it because it wouldn't work with msi mystic light software, these problems began to arise.
It's a bit unclear because you mention having Corsair RGB Pro 3600Mhz memory, yet question if XMP settings align with it.
