Found one error on the second pass, I’m guessing this is all the evidence I need but I haven’t stopped it yet. I may swap the dimm to the other slot to make sure it’s not the motherboard.

Thanks, I’ll try and give this a shot this weekend.

Hello. Over the past year or so, I've consistently been getting a very small number of parity check errors during my monthly scheduled party check (it does not write corrections to the array). I used to not see any parity check errors, even when using this LSI card which I have had installed since 2023. My assumption was that the problem was due to my LSI 9211-8i card overheating, or from the cable being bad. To fix this I replaced the SAS cable, applied new thermal paste to the heatsink of the LSI card, and strapped a 40mm noctua fan to the heatsink itself. This resulted in a reduction, but not an elimination of parity check errors, which to me further signaled that the LSI card was the problem. I ran another parity check, this time correcting the errors, and thought my problem was solved. However, on January 2nd, the parity check showed 1 new error, I ran another check to verify and also am getting 1 error. Timeline if that helps... 2025-11-02 - Parity check completes showing 9 errors 2025-11-25 - I repaste the LSI card heatsink, add a noctua fan, and replace the SAS to SATA cable. 2025-11-28 - Parity check completes showing 4 errors 2025-12-02 - Parity check completes showing 4 errors. At this point, I am convinced I fixed the problem and these 4 errors are a result of the LSI card writing bad data due to heat/bad cable. 2025-12-03 - Parity check with correction writes fixes 4 errors. I assume this is the end of my problems. 2026-01-02 - Parity check completes showing 1 error. 2026-01-07 - Parity check completes showing 1 error. Any tips on how to diagnose this before going out and buying new parts? I feel like it could still be the LSI card, a cable, or one of my drives, but I don't have enough information to make that determination. tower-diagnostics-20260116-1341.zip
