What other methods exist to verify a CPU issue without swapping it out?
The nearest slot to the CPU isn't the one suggested for a single DIMM, which might explain the issues you encountered. In another scenario, if either (both) of the 5500's IMCs are defective, even with normal RAM, the test will still fail no matter which socket you choose. I assume you're referring to slot B2, the one farthest from the CPU, as advised in the manual (pages 1-10). As I mentioned before, did the Ryzen 5500 come new or used? If it's second hand, its condition is uncertain. The previous owner might have pushed it too far, leading to potential damage. https://forums. Do you still possess the original CPU and the Gigabyte X370? If yes, you might re-test the RAM in your old system using Burnintest. It's common for pairs of RAM sticks to fail, particularly if they've been exposed to static electricity at some point. I received over 100 units of second-hand DDR3/DDR4 memory, and seven of them failed MemTest86. Memory performance isn't always permanent; it can deteriorate over time. This is understandable given the nature of the software, which is crafted to expose weaknesses. A system may function normally under typical conditions but collapse under extreme stress. I believe some of my stable setups could also fail Burnintest, especially if they include overclocked CPUs or RAM operating at high XMP levels. Even with the standard BIOS, certain tests might reveal issues due to suboptimal RAM, CPU, or motherboard combinations. Not every negative result means total failure; if the system rarely faces such conditions in real life, it's not surprising. As a systems engineer, I'm accustomed to stress-testing equipment across a wide temperature range—from -51°C to +55°C. I routinely perform drop tests, bump tests, vibration tests, humidity tests, and more to evaluate reliability. Similarly, EMC and EMI testing are standard. You must carefully decide which tests to run and how to interpret them. For instance, I wouldn't operate a typical PC at -51°C or +55°C, nor would I conduct a Milspec drop test. Burnintest could be pointing out genuine issues with your current components, which may require replacing some parts. Sorry. This is where things began to go awry. Could it be the 5500 that's at fault? If my assessment is correct, you haven't personally tried any new RAM. You can keep testing your existing RAM until it's clearly problematic, but passing all tests doesn't guarantee it will fit or perform well with the 5500. Some RAM packages designed for Intel CPUs don't translate well to AMD systems. That's why certain kits include specific EXPO SPD timings for AMD. Make sure to verify your exact TridentZ RAM part number in the motherboard's QVL. Note: I rely on QVL mainly as a reference. I often use RAM not listed there, and occasionally purchase second-hand units. Performance varies—sometimes it works, other times not. Think about replacing your RAM entirely. It's one of the few components you haven't altered. It's a harsh reality: when problems arise, they can become costly (as I've experienced).
