Not supported to use RAM above XMP3 or stock levels.
System built with Intel i5-13600k and a water-cooled setup featuring AlphaCool Eisbear and Thermalright frame. Powered by Gigabyte Z790 UD, Kingston Fury Beast 2x16 at 5600Mhz, paired with a CL40 RTX 2070 Windforce X3 (water cooled, Bykski block). Includes beQuiet Straight Power 11 750W, dual SATA SSDs, and three SATA HDDs. Cooling system uses a custom loop with two 280mm fans, two pumps (one in the Eisbear, one in Aquastream XT), managed by an Aquaero 6 Pro unit. Temperature readings stay consistently low—RAM and VRMs never exceed 50°C under full load. CPU reaches a peak of 87°C (183°F) during prime95 small FFTs, while water stays below 40°C. I haven’t encountered any cooling or power-related issues despite recent upgrades; the PSU was specifically chosen for this build and matches the age of CPU, RAM, and motherboard (around six months old). Earlier this year I swapped my 7700k for this model, but the system only boots with stock or XMP3 settings. Any adjustments to RAM timings or clock speeds cause a no-start, and changing performance options also results in failure. Even raising voltage leads to complete failure. I miss the straightforwardness of older setups where tweaking was possible without risking instability. With this configuration, I feel the system is either fully functional or not at all. Any advice on getting RAM to run at least XMP1 would be greatly appreciated.
Based on my observations with the system, it behaves differently compared to older Intel boards—it loads many settings but remains highly unreliable. The instability tends to appear intermittently, which is the main source of frustration. If you plan to adjust RAM settings, switch the board to safe boot mode first; this usually resolves the issues. Initially, I’d address the BIOS version and reinsert the memory, prioritizing whichever is simpler. Sometimes a specific BIOS revision only supports one memory type, leading to problems when other components are used. Switching to an older or newer revision could improve compatibility. Replacing the memory would be beneficial since DDR5 is quite sensitive to pressure. Since you’re struggling at such a low speed and most BIOS updates still function at 5600, it’s likely the hardware or firmware itself is the problem. A faulty CPU mount, especially with a contact frame, could also be the culprit. If neither of these fixes works, try remounting the CPU and inspecting for bent pins, or reverting to the original ILM module to verify if the frame is the issue. This situation isn’t voltage-related; it’s clearly a hardware or software concern.
It seems everything is now working. XPM1 is running now. I haven’t completed any stability checks yet, but it boots fine. The latest Gigabyte 11 Months BIOS release included a patch where XMP1 can be used with my memory—this is the update note for the August 29 version. I’m not sure how write protection relates to XMP stability, but it did help. Also, your safe boot advice was really useful and saved me a lot of trouble.
