[mythtv-users] Dual channel for ION

[Josu Lazkano]

Hello, I have a memory dual-channel question. I have 2 ION MythTV
boxes, on first machine I have two 1GB sticks and on the second 2
x2GB. On the second I got 3GB for my system, 512MB from both sticks,
so I suppose that dual-channel is working.

On the first one, there are some display glitches (is a remote one)
and the system has 1.5GB, so it looks that there is no dual-channel
activated.

Do I need to access to the BIOS to activate it? I can not access to
the machine, just remotely (ssh). The board is a Nvidia ION:

CPU Supports: ATOM Serial CPU
CPU FSB : 533 MHz
Chipset MCP7A-ION
Memory Dual channel, Non-ECC, Unbuffered DDR2 Supported, Two 200 pin
DDR2 SO-DIMM slots, Max. to 8GB
Memory Types: PC2-5400 (DDR2-667), PC2-6400 (DDR2-800)

Here is memory and nvidia info:
