Are there any problems when shutting down a Mini PC?
So, did you verify the memory under its standard JEDEC setup or under its specific XMP configuration? Also, I would strongly advise against using "Memtest86+". It isn't the same tool as Memtest86 from Passmark. Obtain the free Passmark Memtest86 utility, execute it for four passes across the complete memory array with the basic default settings enabled, without XMP active. If it succeeds in this scenario, you can proceed; otherwise, enable XMP and repeat the process.
If it works under both scenarios using Memtest86 (not Memtest86+), you might also try Prime95 in Blend mode while disabling all AVX options. If it manages to run for about half an hour without issues, it's likely not encountering basic problems. You could also use the Windows memory diagnostic, which runs different tests than Memtest86.
My main concern remains the shutdown behavior—this could point to a problem with the Beelink unit or the mainboard itself. You might attempt installing just one memory module in one of the DIMM slots and observe if the shutdown issue changes. Repeat this with the other slot. Alternatively, try removing the memory entirely and see if the system boots and powers down normally. Obviously, it won't boot without memory, but you can check if the power button functions or if unplugging is still necessary. Another option is to turn off hibernation in Windows by following these steps:
The initial step is to locate and open the command prompt with administrative privileges. Simply type "command prompt" into any search or run dialog, right-click it, and select "Run as administrator."
Once in the command prompt, type “powercfg.exe /h off” without quotes and press Enter. If you enter it correctly, the cursor will begin at a new line prompting for input.
Now close the command prompt window. Restart your system and verify whether the issue persists.
If problems continue after these steps, it’s likely a core hardware problem—probably related to the mainboard, especially if the shutdown behavior extends beyond the power button on the device case and also prevents normal shutdown within Windows.
I did not modify anything within memtest. Are there any XMP settings in memtest? I didn’t notice anything about XMP or JEDEC in the BIOS. I wasn’t aware that memtest86+ and memtest86 are different. I assumed memtest86+ was the more recent version. I’ll try again using memtest86. Does memtest86 actually check memory differently than memtest86+? My question is, since I’m reading this now, the test with memtest86 shows a very similar layout to memtest86+.
In terms of shutdown behavior, if I run the computer without it crashing and then power it down normally, it behaves almost the same as when it crashes—screen goes black and fans continue running. The only difference is I can press the power button to shut it down, unlike during a crash when I can’t.
After completing memtest and testing various memory setups, I plan to disable hibernation if the issue persists.
By the way, if I discover the problem is on the motherboard, can it be replaced with a new one? Would that require reinstalling Windows?
Thanks in advance for your assistance.
Could a faulty power button be the cause? I reviewed the initial discussion but didn't catch all the details, and my experience seems distinct from others'.
There isn't an XMP configuration in Memtest, yet it should show whether XMP is active. These are general descriptions of RAM delays, but your BIOS might use other words. JEDEC refers to the standard (base) speed of RAM, without any memory overclocking. When people discuss JEDEC, they mean the default timing for the RAM, not the fastest possible. In theory, most motherboards should boot fine when BIOS is set to JEDEC speed, since it's slower than XMP/EXPO/DOCP overclocks. I recognize three widely used phrases for RAM overclocking: XMP, EXPO and DOCP. XMP (Intel) Most consumer DIMMs and SODIMMs include one or more high-speed options (faster than JEDEC) stored in the SPD chip inside the DIMM/SODIMM. Server ECC RAM is less likely to have XMP settings, prioritizing stability over speed. Data reliability takes precedence over velocity in servers. EXPO (AMD) For systems with AMD, you can purchase RAM with specific EXPO timing, which is tailored for AMD chipsets and CPUs. https://www.digitalcitizen.life/amd-expo/ DOCP (Asus) This term appears in Asus BIOS and matches XMP or EXPO. It refers to the area where you can boost RAM speed on an Asus motherboard. When assessing memory stability, I check if XMP/EXPO/DOCP is activated in the BIOS. The quicker you increase RAM overclocking, the higher the chance of system issues. Excessive overclocking may lead to glitches, BSoDs, or even a failure to boot. During MemTest86 testing, verify the speed you're using (when enabled). If errors appear, turn off XMP/EXPO/DOCP in BIOS and rerun MemTest86 at JEDEC default speed. Running multiple full passes—such as four with XMP active and four without—is recommended, though I usually stick to one pass per speed until I settle on the best setting. Errors under XMP but not under XMP disabled suggest instability; you can try adjusting speeds manually. When XMP/EXPO/DOCP is turned on, BIOS typically picks the highest speed from the DIMM's SPD chip, like 7,000MT/s for modern DDR5 RAM. If this speed becomes unstable, consider lowering to slower SPD speeds such as 6,800, 6,600, 6,400 down to 5,200 or 4,800MT/s (standard JEDEC for DDR5). Tools like CPUID CPU-Z can help identify the SPD timings in your RAM. https://www.cpuid.com/softwares/cpu-z.html TLDR You might need to perform several full MemTest86 runs at different RAM speeds—starting with XMP and then JEDEC—after setting these in BIOS.
