I'm not an overclocking guru, but since you have "slow ram" I would recommend setting a divider.
Also, the type of ram, and maybe some pics of your bios might help me a little.
Refering to the Sata drive stopping. Have you tried switching sata ports?
Did you make sure your system is stable after the overclock?
These programs are what i recommend:
SuperPi (must have 2 instances running for Dual Core CPU's),
3DMark 05 and 3DMark 06, and
stress prime 2004 (stress prime should also have 2 instances running.
SuperPi - Run in 32M and if you crash your not stable.
3DMark 05/06 - If you crash your not stable.
Stress Prime 2004 - Run in Tourture test in Blend mode for atleast 8 hours. If you crash, again, your not stable.
I would try to keep your temps below 60C.
