Caspita
ho trovato questa appendice al libretto di uso della MB
Addendum 40-051-99660
note of this chipset limitation :
when your system runs at 333mhz cpu fsb , the memory will be automatically set to ddr333 regardless of the type of memory module (ddr400/ddr333)
we do not recommend that you use ddr266 memory module , this is to avoid system instability .
e mò che significa?
