Seems one dimm allows for much more RAM tweaking (instead of two in dual channel)

I am lending one of my Team Xtreem dimms to a good buddy while he awaits arrival of his own RAM.

So naturally, i had to see how things run with one 1024 MB dimm instead of my normal two.
Waste of time?
Yes, but eh :)

I figured some SuperPI freaks might find the results interesting.
I wish i could run game benches for this, but we all know the difference is too minimal & it would take too much time.

I found i could tighten subtimings a lot more than previously with two dimms in dual channel.

System:
Asus P5B Deluxe WiFi-AP bios 0711
Intel Core 2 Duo E6300 @ 3402 MHz (7x486) 1.40-1.42V
Team Xtreem 1024 MB DDR2-1000 5-5-5-15 @ DDR2-972 4-4-x-4 2.25V


Super PI 2M results (averaged from at least 3 runs)
Bolded text shows what was changed since the previous run.

For those with P5B series motherboards, you might wanna mess around with those last four subtimings especially :) (aside from obvious primary ones).
