You have a locked CPU, that means that we need use the FSB for overclock the CPU, but that FSB also affect the NB, HT and DRAM frequency. Slow down the RAM frequency ratio to the lowest possible, rise the FSB in little steps 10MHz or so and try to keep the NB and HT frequency at ~2000MHz. Test the stability with prime95, LinX, OCCT or y-cruncher for 2hours or more.
