Almost stable for 8 hours of prime at 210x21 for 4410mhz (with HT on). 1 thread decided to die at 1hr 40m. The other 7 made it.......... GRRRRRRRRRRRRR
800MHZ was the norm at the start av i7 C0, but i7 has evolved and most D0's will do @4.2-4.4GHZ 24/7, and this is the BCLK210 territory. 840MHZ has become the "not so nice an round" number that creates a big RAM-dilemma (many sticks can't run at this speed even with higher voltages). I guess many of these "strange" stability problems starts when people try to push the RAM over it's limits.
