q9550 where to go from here

Ok, this is the original article which influenced my opinion on loadline calibration:

Even before I purchased I had read about this subject as it is potentially the single most important thing to understand with 45nm chips:

There is so much on google about loadline calibration. There is one camp who say its fine but clearly don't understand what its about and the other who is aware that "its out of spec for intel" and will wear out your chip if not wipe it out:

finally got it stable at 3.6ghz this evening. Cranked the voltage up to 1.275v

Might have to give 3.8 a blast now

Temps idling around the 35 - 40 degrees depending on what temp reading i use. Load around 65 - 70 so still quite good.

Temps are still OK.

Set Vcore at 1.35 , and just up the fsb in increments of 20 untill it :

Won't post
or
Will post , but the stress temps are 75+

LLC made the difference between my Q9650 running stable at 4.05Ghz and failing IBT, still at 1.35v.

Read the artical I linked to. There are still plenty of nay sayers and you may find no problems but voltage spikes are damaging just like high vcore. Ever had a light bulb blow when u flick the switch? For something already in a weakened state its the back breaker. I had a PSU blow when i flicked the wall switch while the PSU switch was closed, now I turn everything on separately starting with the wall socket.

A Prof of electronics said that leaving a PC on was safer than turning it on and off. Sure its designed for that but its best to keep it to a minimum.

think my limit is going to be 3.7ghz, chucked the voltage up to 1.3 and it failed around the 30th pass of IBT so although i could have put the voltage up to make it stable the temps would be creeping up to around the 70 - 75degree mark so just put it back to 3.6 although may even drop it back down to 3.4 to keep the idle temps around the low 30s rather than the high 30s

Thanks to all who helped with my questions
