A7N8X Deluxe and the dual-channel feature

[Ralf Eckert]

Hi NG's!

using the A7N8X with 2 new 512 MB DDRRAM DIMM PC400 Corsair TWINXLL but cant
use the performance. i pluged the ram-modules in the ram-sockets 2 and 3
[blue colered]. in the BIOS-boot the ram-modules will be identified as
DUAL-channel_modules. the benchmark result of sandra-soft ascertained, that
the ram-module is running in date item size 16 byte and a daterate of
aproxematelly 2500 MB/s. the manual give the advise "to enhance system
performance, utilize dual channel feature" but how / where can i make this
settings?

best regards and thx in advance

To utilize dual channel memory feature install the DIMMs in any of the
following sequence: sockets 1 & 3, sockets 2 & 3 or sockets 1, 2 & 3.

Sounds like you have that part right, but have you tried the ram in
slots 1 & 3 to see if it makes any difference, just seems logical to me
to always insert ram into the 1st slot, then add from there.

I score around 2979/2780 in Sandra 2004 @ 200MHz with ram in 1 & 3 or 1,
2 & 3, using Corsair PC3200LLPT (2-2-3-6-T1) 256MB sticks, Barton @
200x11, Memory Frequency @ 100%.
Cheers,

KORREKTION

i wrote in my first question ....ram-module is running in date item size 16
byte
this is wrong, in real, it is runnning in 8 byte-mode

I have the same exact problem. Sandra scores seem real low using such
good memory. I set the Bios to Aggressive and that helped a little but
not much. Have you managed to get better scores, by making any other
changes?
