Hi,
Recently i have been building a machine from second hand server parts (cough linus cough) in order to run FreeNAS with two WD Blue 3TB mirrored drives (new) and a Seasonic power supply (also new). The parts that i bought were...
Intel Xeon X5260 SLANJ
Kingston KVR667D2D4F5K2/8G
Intel S5000PSLSATA
Anyway...
When i was first testing the system with freenas, More often than not the boot process would be interrupted because one of the DIMMs would fail a self check. Because i had purchased these DIMMs second hand from ebay, i decided to make a bootable usb drive with manjaro linux (An ISO that i had on my HDD at the time) and run memtest86+ 5.01 since in comes with the distro's installer.
When running memtest86 with the full 16GB of ram, the sixth or seventh test would always lock up. But after a few unplugs and re-plugs of the ram itself, the test passed two complete passes before failing in the same place during the third pass last night (Something that this computer hasn't been able to do until now). Currently I'm performing another test with a DIMM that i think could be faulty installed, but it has already passed the first pass. Even now I am no longer seeing an error from within the bios during the boot progress notifying me that a self-test has failed.
I don't know much about the inner workings of memtest86 or the FB-DIMMs themselves to draw a conclusion from the results I've been getting, but would it be safe for my z-pool to work under these conditions considering that this is fully buffered ECC that i am working with? Or is everything OK now that The DIMMs are passing self-tests, and I'm an idiot for running memtest86 on these types of DIMMs?
Thank you
