Hi there,
I have a very strange problem with a new NAS install.
I had a Supermicro A1SAi for 5 years before I got the Intel AVR54 bug, which Supermicro absolutely refused to fix. For that matter I decided not to buy a new Supermicro motherboard. Anyway, just to say that the 6 disks (2 SSDs and 4 HDD) and Seasonic S12II 620W PSU in the NAS are 5 years old.
So to fix this existing NAS, I've just bought an Asus P11C-I + Core i3 + 16G ECC.
I checked the BMC sensors today and in one week there was about 3600 incidents in the log. What's happening is that the 3.3v is fluctuating near the low limit (2.8V).
But I'd never had the problem before with the Supermicro.
I thought, right the PSU might be old, or the motherboard has a defect, or the (awful) Asus BMC sensor is off.
But then I noticed something funny in the history:
- the 3.3v is low only when the 4 HDD are OFF
- the 3.3v sensor is showing a straight line at 3.4V when the 4 HDD are ON!
How is that possible?
I haven't opened the case and checked with a multimeter (yet). I'd like to be sure if there's an issue with the new hardware as I have 2 weeks to return it.
