This build has been fun to play with
CPU: Pentium D Extreme Edition 965
Cooler: Noctua NH-U12S with official LGA775 mounting hardware
Motherboard: Asus P5Q3 Deluxe
Memory: 2GB DDR3 1600
Graphics: GeForce 7950 GT

Prime95 stable, needs about 1.3v on the northbridge
I haven’t touched the memory timings at this frequency, so they’re very loose.
According to Intel documentation, Presler core CPUs are rated for a maximum of 1.55v, personally I would not take it over 1.5v
