I just read an O'C thread in overclock.net and it stated that the Intel Core i7 920 has a maximum multiplier of 21x instead of the normal 20x in the "Key Terms and Settings Quick Guide:" -> "CPU Multiplier"
On the 920 the range is from 12x – 21x (22x on one core when at stock speeds). It has been found that the 19x and 21x multipliers are more stable than the 20x.
Now I'm a little confused on the i7 920's multiplier. I have an ASUS P6TD Deluxe motherboard if that would help a little.
So all the rumours I've heard about people overclocking their i7 920 using a 21x multiplier have an Engineering Sample. Is there a BIOS hack that will enable HT on all cores and lock the 21x Multiplier?
