If you go to the CPU support page, and search by CPU (using
the menu in the middle of the page), this is what is
returned for the Opteron Dual. This is all the motherboards
supporting the Dual 165 with their necessary BIOS revisions.
"AMD Opteron Dualcore 165 (revE6) (Socket939)
Motherboard Since PCB Since BIOS Note
A8N32-SLI Deluxe ALL 0703
A8N5X ALL 0401
A8N-SLI SE ALL 0203
A8N-VM ALL 0506
A8N-VM CSM ALL 0506
A8R-MVP ALL 0201
A8S-X ALL 0601
A8V-MX ALL 0306 "
The "AMD Opteron 146 (revE4) (Socket939)" returns the same list
of motherboards.
The A8V-MX is AGP and uses a K8M800. The Via webpage says
"AMD Athlon64 & Opteron Single/Dual Processor Support"
For the A8V and its K8T800, the Via webpage for K8T800 says
"AMD Athlon64, Athlon64FX & Opteron Single/Dual Processor Support"
so maybe all that the A8V or A8V Deluxe need, is a BIOS update.
It really depends whether there is some hidden issue with
the motherboard, with the Vcore providing adequate current,
and whether Asus is still interested in updating the BIOS.
Don't buy the motherboard, unless the processor you want
to use, is listed on the CPU support web page.
