I tested on 3600Mhz and rams on 1200Mhz CL5-5-5-15.

Superpi 1M, 1gb: 14,109s
Superpi 1M, 2gb: 14,07*s

with am2... i forget the exact speed i was running things at but here's how varying amounts of ram affect performance at identical settings


# Channels Amount 1M
dual 2x1gb 28.547
single 2x1gb 28.641
single 1x1gb 29.125
dual 4x512mb 28.547
dual 2x512mb 29
single 2x512mb 29.11
single 1x512mb 29.516

such a big difference. :slobber:
It makes me start to thinking about getting a 2GB kit.:rolleyes:

EDIT: There, "Benching 16/32M/dual32M on P5B Dx/C2D --> 1GB vs 2GB vs 4GB compared!" (http://www.xtremesystems.org/forums/showthread.php?t=114856). I hope it helps a bit... :)
:toast:

EDIT2: I'll move this thread to "Xtreme Pi", if you don't mind...
