Ran into an interesting issue...
For our brand-new RS1221RP+, we purchased 2 D4ES01-8G (yes, genuine Synology ECC SODIMM) and installed them. Ran just fine. But just to be sure, I went into the Synology Assistant and ran the memory test. Failed! err=1 (whatever that means). Then tried again. Then each module individually. Failure every time. DSM 7.0.1-42214.
I now have a ticket with Synology to investigate, and I suppose RMA two "defective" modules, but wow, it's a rare thing that RAM fails, an even rarer event that ECC RAM fails, but genuine-twice-the-price-just-out-of-the-package, and both fail? Does this smell like a problem with the test and not the RAM? Anyone else had similar experiences?
Back story: I originally purchased some Nemix ECC SODIMMs for this purpose, exact same specs (heck, chips are made by the same company as Syno's RAM, as above, 2R X 8, etc., etc.), except 16GB each. They ran just fine, no errors while running, but failed in the memory test. Since they weren't genuine, and the only RAM on Synology's compatibility list is, well, Synology's, I thought I shouldn't take a chance.
