PC fails to start despite using newly installed RAM at full capacity.
Hello, I purchased Corsair Vengeance DDR5 6000MTS RAM (2x16GB), but the system won't start. After replacing my old Corsair Vengeance 5600 units and installing the new ones, the PC worked perfectly. I didn’t enter BIOS via DEL in time, so it booted with XMP enabled at 5600MTS. A Windows Memory Diagnostic showed no problems. When I rebooted and re-enabled XMP to set it to 6000MTS, it stopped booting entirely. Just a few seconds after turning on the PC (before the BIOS screen appears), it restarted but didn’t work. The fans spun, RGB lit up everywhere, yet the display stayed blank. No POST lights appeared at that moment. Someone suggested using an XMP 2 profile. I tried that and the outcome changed slightly: after powering on, the TUF logo and loading circle appeared briefly before freezing for a couple of seconds. Another attempt resulted in a blue screen. It worked on another machine too. Is there anything else I should try? Or should I consider discarding this upgrade and using something lower frequency? Edit: The RAM model is CMH32GX5M2E6000C36, BIOS version 1805. P.S. I planned to sell this new RAM set as part of a build, so please ignore comments about it being an unnecessary upgrade for my current machine. Updated January 25, 2025 by Sandro797
Assuming you're using the 13700KF/TUF Z790 motherboard, please confirm your exact model number. There are several compatible kits available, each with unique characteristics that may require adjustments. To better assist, could you share your current BIOS version and the memory slots you're utilizing? This information helps determine optimal performance settings.
It seems this memory kit often faces compatibility challenges based on different BIOS versions. With the latest BIOS from ASUS for your board, those issues might still exist, especially given the instability of the 13th generation. I’d bet the newest update doesn’t fully resolve it, and since LGA 1700 is no longer supported, you probably won’t get a better fix soon. If you need to return it, consider doing so—you’ll likely find more suitable options for the cost, though you might have to settle for slower performance.

Besides checking if the sticks are defective or if there’s a BIOS issue, have you tested each stick separately? To ensure one isn’t limited to 6000Mhz, make sure you’re using the most recent BIOS version—Intel has had issues with 13th and 14th generation CPUs.
