Intel Motherboard revision question

[imported_Sartori]

Hello

Just had a question about the Intel D875PBZ motherboard. I noticed on newegg and other sites that the mb description says Prescott ready(looks like the retail versions) And the oem versions say not prescott ready.

Also some sites don't say either way if its prescott ready or not. I went too Intels mb site and found a table listing what processors work with what mb revisions. All mb revisions work with non prescott processors but only certain revisions(the later ones) work with the processors. And from the looks of the table the bios isnt a factor as p20 and higher work with all processors.

So I guess what I'm asking is what did they do in these revisions too allow the mb too work with a Prescott processor?

And I guess the only way too tell if I get the right MB if the retailer doesn't say is too wait till it comes and look at the revision number?

Thanks!!

They beefed up the voltage regulation system to the "FMB 1.5" spec to support the power-hungry Prescotts. You'll note that the latest revs (301 and up, IIRC) support "FMB 1.5". That's the secret.

Hello

Thanks for the reply, that clears things up a bit.

You mentioned that 301 and up support it but on that table on Intels site it says that the following revisions support it:

C26680-206 or later
C27085-207 or later

Yeah, I was going from memory, that's why I covered my butt with the "IIRC" comment! My poor brain is overloaded with Intel PCN's and Intel's site isn't the easiest to navigate.
