ReadyNAS RNDU6000 memory upgrade - won't boot
I bought the ReadNAS Ultra 6 with 3x3TB disk in 2011. Upgraded to OS6 long time ago even though it was not supported. Been running fine since! Few years ago I dropped using "apps" in favor of docker ...
Sounds like either bad memory or incompatible memory.
Did you try booting with just one of the memory sticks in place (trying both of them)?
Thanks for the fast reply! I just tried both DIMM seperately and they both work! In both slots. So its not the DIMM's and not the slots on the board. They just won't play noce together...
It's 2x2GB. Would this be an BIOS issue?
I've never tried taking an Ultra6 beyond 2GB, but it has been my belief that 2x2GB should work; and your memory does have the proper rating. I don't believe 8GB will, though that doesn't affect you. Does it work if you mix the old 1GB stick with one of the 2GB's? None of the legacy desktop NAS use dual-channel memory, so mixing different size sticks will not have any negative effects.
According to what I've read on the forum in theory 8GB could be possible but is unconfirmed. 4GB has been done and confirmed. That's why I went with 2x2GB.
Anyway I would have tried mixing DIMM's if it wasn't for your sugestion (note the dual channel...). I just booted the nas with the original 1GB and the new 2GB and that works to!
It doesnt make sense to me yet but this is 3 times more memory than this morning already :)
Appreciate your feedback!
