Arrived on time and easy to fit. Seems to be working well. A very good price.

Amazing product in line with expectations. Quick delivery

Ordering and Product is good, no problem with instalation. Only one problem delivery was late 1 day as was stated on delivery date.

Terrific. Delivered as expected. Out with the old in with the new all worked perfectly

My QNAP TS-h973AX recognizes both 16Gb RAM modules all right, but considers that only one is 'usable'. Any idea about what causes the problem?
