A-Data DDR3-1333+ CAS 7
Its products might have a great reputation, but A-Data’s model number system has an uncanny ability to make its parts difficult to find. Labeled as model number AD31333E002GU3K, the package we received is actually sold as part number AX3U1333PB2G7-3P, and one must visit http://oc.adata.com.tw to find that these are actually the same products. Future Core i5 users will be pleased to note that the modules in this triple-channel kit are also available as dual-channel part number AX3U1333PB2G7-2P, which just as confusingly cross-references to model number AD31333E002GU2K.
Rated at DDR3-1333 timings of 7-7-7-20 at 1.65 volts, conservative SPD values make these bootable at full speed and default voltage. A-Data does not endow this “+” series memory kit with Intel XMP technology, so users must manually configure motherboard BIOS to reach rated performance levels.
Our most recent search found A-Data’s part number AX3U1333PB2G7-3P 6 GB triple-channel memory kit at a moderate $113 Web price.
