Problem encountered when upgrading RAM, no display appears.
Problem encountered when upgrading RAM, no display appears.
I purchased new RAM and after installation it doesn't appear on the display. I'm upgrading from DDR4 16GB 2666MHz to 16-18-18-38 1.2V to DDR4 32GB 3600MHz 18-22-22-42 1.35V. The computer starts up but still shows no screen. I've changed the BIOS to XMP, tried manual settings at 3600MHz, set it automatically, and even removed the CMOS battery, but nothing works. I'm seeking advice since everything I've read says compatibility is confirmed. Please let me know if I'm missing something or overlooking a detail. Your help would be greatly appreciated.
When purchasing your new RAM, did you check the MoBo memory QVL beforehand? Or did you simply choose whatever caught your attention? Did you acquire two separate DIMMs, or was it a single sealed package that came as a kit? If older RAM still functions but the new RAM doesn’t, there might be a problem with the new unit. It suggests your new RAM should be at least twice the capacity of the DIMMs. Running one DIMM at a time could help identify if one is faulty—rarely do both fail simultaneously. XMP settings aren’t a certainty, particularly for RAM not listed in the QVL. JEDEC speeds are guaranteed to be 2133/2400/2666 MT/s; higher speeds don’t ensure better performance but indicate the maximum possible rate. In BIOS, start by testing a single DIMM at 2133, 2400, or 2666. If it works, proceed; if not, the DIMM is likely defective. Then test the second DIMM. If neither functions even at JEDEC speeds, consider discarding the RAM. For more details, see this forum discussion: https://forums.
Perhaps this is something you can grasp. How are you adjusting the BIOS settings without any visual output? Or are you asking if it doesn’t start with Windows? I think you’re probably assuming your device has a graphics card. Have you also checked the IGPU ports on the motherboard, as your CPU supports this feature? If you don’t have a real GPU, memory becomes even more critical because the IGPU takes up part of the main system memory.
If it boots into BIOS but not Windows, try creating a USB bootable version of memtest86+. This should at least get started. You can then run it to check for memory test failures. While the specifics of which tests fail aren’t crucial, it lets you experiment with different memory configurations. Tuning memory is largely a matter of trial and error.
