Yeah, I have to say that I was surprised at the HT on vs. HT off results as well. I expected to get at least another 70MHz to a 100MHz by turning off HT. Other than a slight voltage difference (lower) and additional 23MHz I could not get anything. 1MHz higher BCLK from 206 (HT on) or 207 (HT off) and I could not even load up Windows, regardless of the voltage. I messed around with a lot of settings like IOH/ICH voltages, clock skewing, etc., and nothing made a difference. I think that the chip is probably flaking out at this point. Quite likely more extreme cooling like Phase or LN2 would allow me to break through this barrier though I really do not have money for it
One big downside is that like a lot of the i7 920s that do not like their stock 20x multiplier this chip also does not like its stock 22x multiplier. 21x is good, 23x is good but 22x requires substantially and unpermissibly more voltage to hit the same clocks. This leves me with a choice of running at 21x or 23x and 21x with my max BCLK maxes out way below my current OC.
In relation to the memory, I have to say that those are very impressive timings. I have always been a fan of Mushkin memory since I found that they are very reliable over long term in addition to overclocking decently. Coincidentaly I was just looking at their stuff yesterday but there was no mention of high performance sticks like the ones you have pointed out. Where did you read that article?
