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

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

same settings, no tweak,fresh xp.

SPi 32M I'm not remember exactly, but surely more than 10sec.

can you make it clear and state 2X512 vs 2X1GB or 2X1GB vs 1X1GB

2x1GB is faster but usually 2x512MB can oc higher

[ozzimark]

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

4x1Gb would fly on AM2
Bank interleaving, thats it.

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

I remember I did a little comparison a while ago, benching SPi32M and dualSPi32M with 2x512, 2x1GB and 4x1GB on your motherboard (P5B Deluxe). Let me dig it out...

EDIT: There, "Benching 16/32M/dual32M on P5B Dx/C2D --> 1GB vs 2GB vs 4GB compared!". I hope it helps a bit...


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

[andre X_X]

wow, your thread explain it all... , Great test

btw, sorry for post in wrong section..
