You can add pictures. You just have to put them inside of these brackets
But to respond to your question....
1. You probably already know that the i7 has an integrated memory controller, this memory controller will run the ram at a 2:8 ratio. This ratio is in effect with the base clock. The base clock is at 133 if your not overclocked.
Since its a 2:8 ratio and a 133 base clock your memory frequency will be 1066.
2. Any thing above a 2:8 ratio is considered overclock, but 9/10 times it will work fine.
3. The reason it says 533 in cpu-z is because your ram is DDR (double data rate) so whatever it says in CPUz, you double it and that is your real memory frequency. So right now your ram is running at 1066mhz.
4. To fix your problem you need to go into your bios and change the ratio to 2:12 so you will get a ram frequency of 1600mhz. Then you will need to go into the voltage selection and raise the VDIMM to 1.65 so it doesn't crash.
