The first is CPU Stress Testing only, with multiple blend tests (8-32 integral information).
The second test tests both the memory and the CPU together, the CPU test in this case is almost identical to the previous test, however large stress is placed upon the memory.
The third is a custom option, where you can define set values for stress, to test different parts of the processors stability.
Running option 1 (if this is what you are specifying) is perfectly fine. However, running the second test will have a higher chance of detecting a possible error, and therefore is a better way of testing stability.
Please be aware, that running option 2 will limit what you can do with your computer while the testing is active. This is because most memory is being paged and addressed.
