DFI Lanparty Dark P35 T2RS + Q6600 GO Overclocking Results
Alright TSki, here's the info you wanted...I'm not finely tuned because I'm so content with how stable it is, I don't wanna start tweaking again yet...so I'm sticking with 400FSB/3.6GHZ/DDR800. It's doing great for me, 1.44v under load thus far.

Read Delay Phase Adjust -
ALL ON AUTO, both channels read 7-7-7-7-7
Messed with a little bit, but with a 333 divider it seems lowering performance
level down to 6, which is what this allows by pulling the down per cycle (?)
adds some instability and from what I've read is best left on auto.
With power saving features on, my CPU idles at 2.4GHz with 1.37v..sure it would be nice to have it down around 1.3v or lower, but temps are in low 30's to upper 20's at Idle so I can't complain, then under load I hit the mid to upper 50's, occasionally touching 60-62C, with 1.44v under load. My goal was 3.6GHz and I made it...dunno if I can pull off hitting DDR1000 speeds with my 4 dimms full...I may pull one 2GB kit out and see what I get, sure it'd be fine with a single 2GB kit as I verified both good at DDR1000 speeds seperately before I got the quad. But I did some tuning so DDR800 speeds nets some decent results in Everest's Cache/Memory Benchmark.
8122 Read, 7224 Write, 6980 Copy and 60.9ns Latency...sure it doesn't match my DDR1000 stuff, but before finer tuning (this was initial tuning) I was getting 7621 Read, 7225 Write, 6517 Copy and 63.8ns Latency...so while not huge, it was a decent performance benefit from going More Aggressive and Fast on some settings, and adjusting sub-timings some more. Most of the sub timing settings I adjusted are from popular recommendations for sub-timings in general on a thread I found for OC-ing my DK T2RS board...they work well, and are stable so I'm happy. I may still try for DDR960 333/800 or maybe even DDR1000 266/667 in the future again, but getting Memtest to pass either before even booting to windows has been a pain with 4x1GB...I may feed more NB voltage when I do, but for now with a small 30mm fan on my NB I'm around 39C idle and around 44C load (stress testing).
Hope this helps!
