[H] Extreme edition

[Winterlight]

I have an Intel Q9650 processor.  A friend has given me one of his 
old processors = Intel® Core™2 Extreme Processor QX9650 which is the 
extreme version of my existing processor. He has never over clocked 
it... he didn't know overclocking is what made it extreme.. at the 
time he just wanted to buy the fastest CPU available.

The whole purpose of an Extreme edition is overclocking.. 
correct?  Is an unlocked clock the only difference between the two 
processors, or does the Extreme addition have more to it then that. 
Is an extreme edition more likely to overclock higher then a standard 
CPU or is it still random results. There was a huge difference in 
price... my friend paid a grand for it and I think I paid 450 for 
mine in 08. The Extreme was twice, or more the price of the standard 
QX9650 so there must be more to it then a unlocked clock.

I have a Q9650 with an Arctic cooler Freezer 7 Pro 92mm CPU Cooler, 
but I was not able to get mine above 3.4 without failing burn in. I 
was overclocking at 3.4GHZ and ran OK, however, many months later I 
lost one of my 4GB Patriot DIMMs. I got nervous about the 
overclocking, so I went back to defaults.

The advantage of being able to change the clock means that you won't 
put any other components at risk like you do when you increase the 
FSB speed...correct? Any tips on overclocking this CPU? It would be 
nice if it would run stable and cool at 4GHZ  without killing any 
other components :)
