My system configuration :

Mother board: A7N8X-X
Power supply: 300 Watt
2 x DIMM 512 MB – DDR – 400 Mhz
CPU: Sempron 3000- socket A

Bios upgraded to revision 1010

CPU Jumper FSB on Mainboard set to 1-2 (400/333/266)

On boot I get Sempron 3000+ but memory runs at 200 Mhz single channel mode.

I’ve tried several combinations on Advanced Chipset Features Setup to get Double channel mode for memoy speed but hopelessy.

Best setup achieved with CPU ext freq.166 Mhz and multiple setting Auto. If I set 200 Mhz ext. freq. For CPU I obtain black screen and to start again power off is necessary.

As I understand it I should read 200 Mhz / double channel for memories speed (if Bios is set properly).

Anyone can supply some help?

No dual channel support for the A7N8X-X

Your board uses the Nforce2 400 chipset; only the Nforce2 400 Ultra from Nvidia and the KT880 from VIA support dual channel. In all honesty though, you will not see a HUGE performance difference with dual channel.

Many thanks for the explanation about the slight difference between 400 & 400 Ultra. I didn't notice while I was reading specifications.
As my knowledge of today's computer hardly fills a cup of espresso coffee (very small) I'll consider a new motherboard (surely more disappointments) or some old hobby like model helicopters flying (frustrating after every crash) or glamour photography (closer to heart attack after every session).
Many thanks anyway and keep in contact.
