A7N8X dual ch. ddr/sisoft sandra mem benchmark

[VincentVega]

I recieved my 2 new Samsung PC3200 dimms today. Hoped to increase my memory benchmark results significantly, by enabling the nforce2 dual channel DDR feature.
But it fails. Almost no advantages in SiSoft Sandra.
Nearly the same result, as with only one dimm.

Very disapointing...

Any comments ?

Are you using the correct memory sockets? I just set up this same motherboard, and if I recall, the manual said that in order to take advantage of the dual-channel feature, memory must be in Sockets 1 & 3, Sockets 2 & 3, or sockets 1, 2, & 3. That means, if you use sockets 1 & 2, you will not be using dual channel.

I tried each possibility.
2045/1965 is not that much.

2x Samsung PC3200 @ 444 MHz 3/3/3/5 timings
Athlon XP2100+
A7N8X Deluxe
newest bios

The RAM needed to benefit from this must be running in the slots mentioned and be running/set at Cas2T....so back off the FSB speed as Sammy's, Crucials and others are Cas 2.5T

I'm getting rather low scores as well. Running @ 133 FSB and the memory in sync, I get 2085/1975 using 2,2,2,5 timings ( 2 x 256MB Crucial PC2100 ). I've updated the drivers with no effect.
