AbitBX33-RAID + Tualatin??

[dereklapointe]

Hey All,
the newest BIOS update for Abit BX133-Raid states it now support the Coppermine "T" .. I presume this is the Tualatin? I searched the web and found spotty information the BX133 supports the Tualatin. Anyone have any experience or know people who sucessfully havethe Tualatin running on Abit BX133 RAID?

It just cant be. if the Tualatin needed just lower voltages, it would have worked. but Tualatin changes something more than the voltage.

It is a completely new 0.13 micon process product (anyway not concerned with chipset support) working on lower voltage, and has changed the clocking mechanism from single ended to differential clock.

The BX chipset does not support it. Even the i815 had to be revised to a B0/B2 revision to support it, and for example, Asus produced TUSL2, the CUSL2 version that supported Tualatin.

Since intel has already stopped producing BX, i dont think they have even revised the BX chipset to support Tualatin.

But if they have a new VRM (Voltage Regulator Module) and some means to decouple the clock between the processor and the chipset (I suppose the new VRM does exactly that) the BX might support Tualatin. But thats more than a simple BIOS update. It needs a new board.

The <A HREF="http://www.abit.com.tw/eng/product/mb/bx133.htm" target="_new">Abit BX133-RAID</A> page does not say it anywhere, and their BIOS is still ver 1.0.

Here is what Anand says:
ABIT has released an updated BIOS for their Socket-370 BX133 RAID that claims support for the <i>Coppermine-T</i> CPU. Note that this isn’t a 0.13-micron Tualatin CPU, rather just a version of the 0.18-micron Coppermine core that this BIOS update happens to support. The BX133 RAID as well as all other motherboards that don’t support the VRM 8.5 specification will not work with the Tualatin.
