X-bit Labs has written a review of the Intel DX48BT2 motherboard, the site says this is a specialist motherboard but found that it's no good for overclocking fans.
As for the BIOS that proved pretty inconvenient for overclocking needs, don’t take this mainboard to be an overclocker product (since we failed to overclock the CPU on it anyway) and it will be simply perfect. It is a good Intel mainboard, although it is not really meant for you. It is targeted for system integrators and specialists. The Security options in the BIOS are way too sophisticated for home use, although they will be very handy for corporate customers who never needed any overclocking functionality in the first place.
Pretty strange. Second mainboard from Intel with overclocking functionality that wasn’t really put to good use. Maybe we have “faulty” CPUs? I supposed that maybe Intel DX38BT mainboard was designed for new 45nm processors, while I checked it out with old 65nm ones and that was the reason I failed. However, the situation repeated again with Intel DX48BT2 mainboard and new CPUs… Could it be me then? Possible, but so far I didn’t have any problems with other manufacturers’ mainboards. So, maybe it is still Intel boards that are to blame here?
You can’t make a good overclocker mainboard right away. Is it the third Intel mainboard with overclocking functions or the fifth one? So what do you expect? Despite tremendous experience, Intel is still a newbie in overclocking.
