I have got to RN4220 Rackmount NAS which both have installed 4x4GB of ram. Can i expand ram to 32GB per NAS with whose RAM SAMSUNG 8GB 1Rx4 PC3 14900R M393B1G70QH0-CMA 1349 ?
I cannot find any compatibility list of ram to RN4220 NAS.
I have previously upgraded a 3220 to be a 4220 equivalent (replaced CPU and added RAM and 10GBE card), but I'm foggy on which memory it took. But I think it was unregistered ECC, where the part you are asking about is registered.
What memory is currently installed? If it's unregistered, you need to stick with that.
