Okay I found the original 8gb stick of ram from the original pre-built the NAS is built from, so I tried it and it’s not throwing any errors in memtest. I’ll see if that changes after some usage

Maybe this is an issue with legacy mode vs UEFI? And what is the usb drive partitioned as? MBR or GPT? Maybe you could try the other partition

Maybe you already tried this, but I have messed around with these settings, and in my bios they are for either having the OS control the power management, or the motherboard bios itself. So if you just disable them all (like the “Native ASPM power management” or whatever it’s called), that lets bios have control of power management instead of the OS. Since you have pcie_aspm=off set on the OS, maybe you want to switch back the appropriate bios settings to enabled or auto so Unraid has control. Because based on your description it sounds like it might be the motherboard bios doing some mindless energy saving.

Since UEFI is preferable, I’m wondering why I don’t read much about MBR vs GPT partitioning of Unraid’s USB flash drive. I understand to enable UEFI you have to have the folder called “EFI” instead of “EFI-“ But is that really it? Everywhere else generally emphasizes having GPT partitioning for UEFI. I can’t seem to figure out the interaction between this, and the ‘Launch CSM’ and ‘OS Type’ (“windows UEFI” or “other os”) settings in my bios (an ASUS H110i, with i5-6400), which affect legacy support / UEFI / secure boot in different ways. My understanding is that I want UEFI, but no secure boot. I also have read about possible issues with the Intel iGPU not functioning under some of these settings, and indeed I will get a blank screen if I disable CSM.

I am concerned about damaging the healthy sticks I have in my other PC, because I instead tried the problematic sticks in that PC with the Windows memory diagnostic and they failed there as well. Is this too paranoid? I mean it proves that the sticks are definitely now failing irrespective of what computer they’re in, but the question is if the NAS machine will kill other ram I put in it. I’m in the process of RMAing the 2 bad ram sticks, and if they approve (which maybe they won’t, because it’s 2 sticks), I’m worried the replacements will see the same fate. The generic PSU is from the original pre-built, and it is about 10 years old at this point. Is that a possible source? I don’t see other problems other than the ram failure, however

Unfortunately I tested the ram sticks on a different machine entirely with the Windows memory diagnostic and they both failed. That computer has 2 sticks of the same ram that do not fail. I’m in the process of RMAing the bad ram sticks. But Im worried the NAS will destroy the replacement ram. I would try the 2 healthy ram sticks from the other computer if not for the concern. The other possibility is that because these sticks were originally in the other computer (For 4xgb total sticks), that they got fried in that machine somehow, since it’s a more powerful PC that I was fiddling with (Running XMP etc). That was also using all 4 ram slots, so perhaps the stress on the memory controller damaged these particular sticks somehow? They were both pulled from the matching dual channel slots (dimm_a2 / dimm_b2)

What are the chances that 2 sticks of ram would both fail? These are 8gb Corsair vengeance ddr4-3200 being ran in a rehoused Asus prebuilt (i5-6400, H110i motherboard, generic 300W PSU). My BTRFS cache pool was having corruption errors and a lot of things were going wrong and I thought it was from an unclear shutdown, and was about to reformat the cache pool. I also just upgraded to 7.2 But I figured I’d run memtest86, even though I used this RAM on a different computer and didn’t have problems (from what I could tell) But every memtest I run is throwing failed tests regardless of configuration. It seems unlikely that both sticks would randomly fail. Should I bother buying new RAM? looking at prices, I could buy another PC used with the same specs or perhaps better for about the same price (and maybe have better NICs, lower power usage, etc)
