The Biostar website and the manual both only reference the P4 cpu's as being compatible.
However, I was looking around and noticed that there are socket 478 mobile Core 2 Duo's with a 800mhz FSB and low enough power rating that it seems "possible" to work in my desktop computer. Example CPU's are the T7250, T7700, T7800).
Has anyone out there tried this?
Yes, I know over all performance would be better getting a new board, current generation CPU etc... I was just seeing if the swap was possible. I have seen some of these processors at a fairly low enough price to make me consider the "upgrade".
Not so. If you follow THIS LINK you will see what is compatible with that motherboard. Yes, the chips you mentioned/linked are all PPGA478 but your board has a socket 478. There is a difference and they're not compatible.
