The one I'm trying to get back was running between 3.0-3.1GHz depending on what board I was running, stable......at stock volts. Most I ever got to was around like 350 or 360 FSB, was like almost 3.4GHz I believe, suicide voltages (1.55v on air, safe but not with my cooling for stability), and the only reason it wasn't stable was because the board topped out around 335-340 or so stable. I believe I got my "record" speed (I was in the top 10 on HWbot for a while with it) by booting in at 340 FSB (highest I could boot with), and I used Clockgen to get it up higher for suicide runs.
That same CPU had also ran 2.8GHz (312 x 9 I believe) during the summer months at only 1.20v (stock is 1.35v). Did that when I had high power GPU's and not enough airflow, so needed to keep CPU temps down lol.
The RAM I had at the time was 4x1GB Corsair XMS DDR400 CAS 2.5 that I had zero issues getting up to DDR667 stable out of them at 3-3-3-8 timings, or up to DDR575 or so speeds at 2.5-3-2-5-2T timings. 4 sticks were used for stability and daily use, only 2 of the 4 were used for the suicide runs.
Boards I was running at the time was a pretty decent A8N32-SLI Deluxe that topped out around 335-340 FSB or so. My board was the limiting factor with that CPU, running stable, but that was my daily use board because it was easiest to tune and to get high overclocks with stable, easily. But I had other boards too, DFI's, Abit's, Gigabyte's, and I even had that white Sapphire board at one point. I think I probably played with darn near every decent 939 board back in the day lol.
