Just install 2x 1333 Adata, and seeing the "about my mac" with 1333 in memory slots (may be it is only showing the speed, not actual running speed)
BTW, if you want to test the hardware, please try the MBP built in utility:
To use Apple Hardware Test:
1 Disconnect all external devices from your computer except the power adapter.
If you have an Ethernet cable connected, disconnect it.
2 Restart your MacBook Pro while holding down the D key.
3 When the Apple Hardware Test chooser screen appears, select the language you want
to use.
4 Press the Return key or click the right arrow button.
5 When the Apple Hardware Test main screen appears (after about 45 seconds), follow
the onscreen instructions.
6 If Apple Hardware Test detects a problem, it displays an error code. Make a note of the
error code before pursuing support options. If Apple Hardware Test doesn’t detect a
hardware failure, the problem may be software related.
If this procedure doesn’t work, you can insert the Applications Install DVD and hold
down the D key to use Apple Hardware Test. |
