ecnedac Posted May 18, 2022 Share Posted May 18, 2022 Hello! My unRAID server has now had parity errors over 3 checks - I thought one was a hard power-off, two was suspicious, I ran a third today which found more errors. The only thing I've changed in my unRAID setup in the last 3 months was my main share's disk allocation method; from high-water to most-free. I suspect one of my disks which was unused before but now has data could be throwing these errors. Can anybody help me out? Thanks in advance! tower-diagnostics-20220517-1823.zip Quote Link to comment

trurl Posted May 18, 2022 Share Posted May 18, 2022 Since these were correcting checks, and found parity errors for different sectors, and no obvious disk problems, the most likely suspect is RAM. Have you done memtest? You shouldn't even attempt to run a computer with RAM problems. Everything goes through RAM, the OS and any other executable code, your data, everything. Quote Link to comment

JorgeB Posted May 18, 2022 Share Posted May 18, 2022 Mesmtest is a good place to start, also note that Ryzen with overclocked RAM is known to in some cases corrupt data, though yours is not overclocked by much it still is. Quote Link to comment

That's good to know; I'm planning to run a memtest later today. The RAM I have is rated for 3200mhz. Is it considered overclocking to run memory at its' rated speed? Quote Link to comment
JorgeB Posted May 18, 2022 Share Posted May 18, 2022 It's above AMD max officially supported speed for that configuration, so yes, also if the RAM runs at 3200MT/s only using an XMP profile, not the default JEDEC then the RAM itself is technically also overclocked, RAM that runs a 3200MT/s using the JEDEC profile is not overclocked.

ecnedac Posted June 5, 2022 Author Share Posted June 5, 2022 It turned out to be an issue with my motherboard. I've tested my memory in another motherboard, it tested clean, so I RMA'd the broken one. Thanks for the help everyone! Quote Link to comment
ChatNoir Posted June 5, 2022 Share Posted June 5, 2022 Could be the CPU too, as that memory controller is in the CPU, not the Motherboard. Hopefully, it's only the MB. Quote Link to comment
