If you plan to select P-1 tests as a work type, you should give each test a much bigger amount of memory than the default 8 Mb. Otherwise you will not be performing the tests in an effective manner. P-1 tests are done in 2 stages, and stage 2 will only run if there is enough memory. The chances of finding a factor are much better if you run both stages. I would recommend no less than 300 Mb per core engaged on P-1 tests. Therefore, if you are, say, doing 3 P-1 tests and 3 LL tests on your 6-core system, you should assign no less than 1Gb to Prime95. Note that apart from the P-1 Stage 2, the memory usage of the program is low.
