What is says on the package is what I ordered, but is not what actually received.

Has anyone else had this memory show up as 1600 and not 1333? I installed this into a Late 2011 Macbook Pro. The system took a long time to boot up (about minute and half whereas it's normally about 45 seconds.) I assumed that the long boot was due to the POST calculating the new RAM. After the boot to the desktop, the normal load time for the system and user initiated apps is about 20 seconds. This took about a minute. Again, I assumed it was the first time booting with the new RAM.
I checked "About this Mac." It showed 16 GB 1600 MHz DDR3. I was expecting to see 16 GB 1333 MHz DDR3. I rebooted the system and ran Memtest86+ which passed but no indication of the speed. I then ran Apple Hardware Test. It showed it passed and the speed @ 1600. So did REMBER. The modules say 1333. The package says 1333. I ordered this kit which says PC3 10600 DDR3 1333 so I have no clue what is up with this. I am a little concerned as usually Macs are known to be memory speed sensitive. However, they normally fail to boot if there is an issue with the RAM. Other than the first long boot, it boots fine.
The desktop initialization is fine as are all of the apps I run. It did get hung up once in Safari but other than that, all seems to working fine. So the question is, do I keep it or not. I called Crucial. They were of little help and told me to return it and order the correct RAM. Geez I hate stupid people.
Any thoughts on this?
