1N is 1.5Clocks where 1T is 1 Clock, so you see its better than 2N which is 2 Clock but it never will be 1T.

Skew holes, nope no such thing, you just were not running where it needed to be, micron likes delay and samsung seems to like advanced.

NB GTL is limited on the Premium but 0.61 works best for me at 400FSB or higher and with high load. 8GB I start with 1.3V NB and fine tune from there, it usually will not allow much more.

Command skew will help you boys looking for high 1N performance,for 2N or high memory load I would leave it to AUTO.

0503bios is a wonderful piece of kit, 0401 comes close but 0503 is much more tweakable for me and I have hit my most stable high clocks with it to date, I had higher with 0401 but not as stable at 0503.

Premium is the benchmark board for all others at this time, just the NB GTL is a pain as only 2 options but I can live with that. Presently testing DFI T3R and BlackOps to see how they compare
