Hi all

 

I have the QNAP  TS-451+ (local - currently 2GB) and TS-451 (remote backup - currently 4GB) and wanting to upgrade the ram to 8GB (2 x 4GB).

 

Both are currently using only 1 slot as below.

 

TS-451+ 

 

Memory slot 1 (Channel A, DIMM 1)    2 GB, non-ECC, SO DIMM (Transcend Information)

 

TS-451 /

 

Memory slot 1 (Channel A, DIMM 1)    4 GB, non-ECC, SO DIMM (Kingston) - not sure if additional ram stick has to be kingston only?

 

or if someone can advise if these would work?

Pretty sure I have some floating around if the above doesn't work out.

 

 

 

EDIT: Quick check of the old ram box shows 1 x Adata 4GB DDR3-1600 SO-DIMM and 2 x Samsung 4GB DDR3-1600 SO-DIMMs. Sure I have another couple of 4GB SK Hynix SO-DIMMs somewhere that I actually think came out of a Qnap NAS when upgraded!  ;-)

Just found out that it requires low voltage ram only (DDR3L) - any chance these are low volt?

@Slasher, any luck getting the SO-DIMMs you were looking for? I just came across 3 x 4GB low voltage SO-DIMMs while going through some parts today. Flick me a PM if you're still interested.
