Please can you all be aware that WEEKENDS are in fact Skeleton staff only and answering hexus is only possible when there's a break in the OLQ's and phonecalls coming in.
As such if there are no notes on the system, we cannot get answers like we do during the week and as such we cannot really give the answers until we check and confirm things with purchasing or systembuild and technical.
Anyway, The Asus website Here shows all the motherboards that are compatible with the conroe processors, but we cannot really 100% guarantee BIOS revisions due to having more than 1 active supplier at the present time.
I hope this information helps.
Best Regards,
