I recently installed a new motherboard CPU and RAM to enhance my old system. I received an ASRock Z790M-ITX WiFi with the latest firmware, paired with an i5-13600KF Corsair Vengeance 64GB DDR5 6000MHz RAM (2x32GB). Running Prime95, my machine remains stable only at the base RAM clock of 4800MHz, whether XMP is enabled or not. I’m aware the RAM isn’t listed for this motherboard, and I understand Intel doesn’t support XMP speeds beyond 5600MHz. Exceeding 5400MHz causes immediate kernel panic even under light loads, and Prime95 detects errors at 4800MHz where performance returns. It appears the only reliable speed I can achieve is the base 4800MHz. Could there be an issue with my setup? Am I using a faulty CPU or RAM? It might simply be because the RAM isn’t recognized by the vendor list. I’m unsure how I’m proceeding. All I’ve done so far is enabled XMP and set the DRAM frequency.

The advertised performance of 5600 is achievable at higher speeds, but only if your CPU can reach above 6000. This means you shouldn't rely on that number when deciding to return the device. In practice, official supported speeds for dual-rank DIMMs are around 5200, though you might still surpass it with the right components. I’d start by experimenting with the IMC voltages to improve stability. There are three key settings—System Agent, VDDQ TX, and VDD2—that could be adjusted. If your CPU has unusual needs for these, tweaking them might help. Alternatively, consider updating your BIOS, as newer versions sometimes fix memory compatibility issues. If those don’t resolve the problem, re-mount the CPU and RAM; sometimes loose mounting pressure is the culprit. Also inspect the socket for bent pins, and if that fails, return the RAM or replace it with a better option.

You can check whether the problem lies with the CPU or RAM by testing each component separately. If the issue persists after confirming the RAM placement, it may point to a CPU-related fault. The coolant fan being close to the RAM could affect thermal management, potentially influencing performance. Start by verifying voltages first, then proceed with component inspection.

It really depends on what you're looking for. To determine if your CPU is bad, you need a better one. If the issue lies with your motherboard or BIOS, finding a better board or firmware helps. For RAM, you must identify better options. With some experience, you can guess which part is problematic faster than a third chance, though comparing real parts is tricky. Generally, start with the basics I mentioned first—just the way I would have approached it. If you're planning to install, note that ITX boards often mean SFF rigs, which can be harder to work with.
