ordered the 2 bars (a good price) on 9 January. Although shipment has been announced on 10-1 and prearranged for about 14-01, I sent a message of concern for the 19-01 not received by that date ... of course they were delivered from the 20-01 ... Nevertheless, with AMAZON, I'm not used to such a delay ... But also tested motherboard ASROCK: perfectly compatible same CLAS (6-400 MHz); refresh rate 7.2 micro / S.
