I've been studying overclocking for a few days, and I think I understand the theory behind it, though I haven't tried it yet. I'm finishing setup on a system I just built, and I'd like to try overclocking this processor. I've found several excellent tutorials online that deal with overclocking core2duos on this motherboard, and they all agree except on one point. This is what I'd like some opinions on.
I'm basically planning on following this tutorial, as it seems nice and conservative in regards to heat, voltages, and FSB bumps:

That's page 3 of the tutorial, and it's there that this tutorial makes a popular reccomendation: unlinking the FSB and RAM settings in the BIOS before boosting FSB. However, this tutorial recommends leaving them linked:

I'd just blow this off and go with the conservative guide, except... what this guy is saying makes good sense to me (but I have no idea if I really understand any of this or not, hence my desire for a second opinion ). Here's the pertinent excerpt:
"Linked and Synced baby. In every single over-clocking guide I have seen the first thing they say to do is unlink the FSB and Ram. I strongly disagree. This was a common over-clocking practice during the P4 days of the past, when the FSB was 800Mhz and anything faster than DDR 400 was tough to come by. By today’s standards that would be 1066 and DDR2 533, are any of you running DDR2 533? I didn’t think so. Even I managed to scrounge up some DDR2 800.
So linked and synced your FSB to Ram ratio will be like this…
QDR 1066 =DDR2 533
QDR 1333 =DDR2 667
QDR 1500 =DDR2 750
QDR 1600 =DDR2 800
QDR 1800 =DDR2 900
QDR 2133 =DDR2 1066
This provides what I consider a true 1:1 FSB/Ram ratio..."
Particularly in my case, I can't figure out why I wouldn't take his advice and leave them linked. I'm using an E4500 with a QDR FSB of 800Mhz (with a multiplier of 11), and 2 gig of DDR2 800. So it seems to me that - assuming the apparently optimum ratio of 1:1 - I'd have to push the QDR FSB past 1600 Mhz in order to bump the RAM's limit of 800Mhz. With a multiplier of 11, that kind of FSB would yield a clock speed of 4.4 Ghz. I'm pretty sure that ain't gonna happen...
So, what do you all think? Linked and synched, or unlink and adjust the RAM speed manually? If I did unlink and just used a 1:1 ratio, wouldn't my settings be the same as what the motherboard would do automatically?
I know, this is a long question. I'd really appreciate any help or input. Thanks!
