Personally, I would go with just the Kingston 8GB and leave the other 1333 out. 8 GB of RAM is usually more than enough unless you are doing some extreme multi-tasking.
But, in the light of that, no it won't hurt anything and you could probably utilize all 16GB but at the slower speed. You should put the slower RAM in the first set of slots and the kingston in the second set. This will allow the memory controller to set the speed for all 4.
^^ I agree, but if you can, try overclocking your super talent RAM to the same speed and timings of your kinston RAM and install the kingston RAM in slot 1 and 3. it should work if everything is the same. test with memtest though.
Didn't know if I should start a new thread for this or what.....
But the computer got here and I tried installing the Kingston in slots 2&4. When I turn on the power it powers on and off repeatedly. I don't know what do do here. When I pull the RAM out it starts up fine.
I have used this RAM on this motherboard before, so I don't understand the issue.
