Monstru, what "tweak" are you talking about? The inverse HTT/temp scaling was known since the dawn of time, how did you expect the 3000+/3200+/3700+ etc records were broken?
Actually, a better idea would be to go with a Winchester chip rather than a Venice, back in 2005/2006 those CPUs were known to have less HTT/cold issues than Venice so higher HTT should be possible as well. (personally, I couldn't find one on time so had to use SanDiego for my submission)
