Combining a 2400 MHz RAM module with a 2666 MHz one can boost performance, but ensure compatibility with your system.
Combining a 2400 MHz RAM module with a 2666 MHz one can boost performance, but ensure compatibility with your system.
You're dealing with an MSI H110M Pro VD Plus motherboard running a prebuilt PC setup. After two years, you wanted to upgrade your RAM but found only a limited option available. You chose the GOODRAM DDR4 8GB 2666MHz module, which didn't meet expectations since 2400MHz RAM isn't standard in your region. When you swapped the slots and enabled XMP, it only recognized up to 2133MHz, even though the new RAM supports that speed. Switching slots completely removed the XMP feature, leaving you stuck at 2133MHz. The image shows a setting labeled "DRAM frequency: DDR4-2400mhz (18x100.00x1.33)"—this is the only 2400MHz option available. You're looking for guidance to downgrade the 2666MHz RAM to 2400MHz and ensure proper recognition, but the documentation seems unclear on how to adjust that specific setting.
You need to adjust the memory settings yourself. The 2400mhz board doesn’t support an XMP profile at all—it only uses Jedec, which is why the problem arises. Besides, make sure your memory matches. Mixing won’t help here. Avoid using the XMP option. Just set it manually. I wouldn’t expect to exceed 2400mhz.
I adjusted it manually to 2400mhz, but it only accepts up to 8GB, not the full 16GB.
