stevejst I think you have finally given us the evidence that you need to prove us all wrong. According to you we need to goto Exhardware to see what is needed to get 1.8 Ghz performance.
Your Exhardware link shows the following:
In order to get a 1900+ to go to 2200+ speeds you need:
an OCZ Goliath heatsink
AGOGA Stepping
Arctic Silver 3
a 0.1 volt voltage increase
2200+ is three levels above 1900+ (1900-2000-2100-2200)
an OCZ Goliath is $28 and has a thermal resistance of 0.67 according to
Dan's Data (lower is better)
Some sort of "Thermal Goo" - (Technical term there) should always be used most heatsinks come with some sort for free. There is a debate about how effective Arctic Silver vs generic paste is but I'm not going to get into that here.
A 0.1 volt voltage increase is free.
Therefore according to your logic to get a 1600+ to get to 1900+ (1600-1700-1800-1900) you should need
an OCZ Goliath heatsink
AGOGA Stepping - Most seem to be getting AGOGA or AGOIA both of which are very good.
Arctic Silver 3
a 0.1 volt voltage increase
and a little luck. (I'll throw that in there for you.)
Now here's the interesting part. It turns out that the Thermalright AX-7 has a thermal resistance of 0.54. That means it is a better cooler than the OCZ Goliath. Now I know you can guess what's coming next. Since the AX-7 compares directly with the GC68 that means that the GC68 ($6 cooler with a Delta fan on it) beats the pants off of the $28 Goliath that you claim is what's necessary to overclock an Athlon.
So here's the big expense you should incur to overclock your Athlon:
GC68 and high powered fan - about $10
AGOGA or AGOIA stepping - most seem to be getting these, it's the luck of the draw
Arctic Silver 3 - $6 if you don't already have some or free if you're willing to try generic paste
0.1 volt voltage increase - FREE
Total MAX cost $16
I'm pretty sure that if there was someone who wasn't convinced that you know what you're talking about you've finally put them in there place.
