Ok, question, what Front side Bus is Kentsfield supposed to debut at?!?!

Are we expecting 1333 for it?! Im curious if todays mobo's will be ready for that speed...
 
Question is because id liek to byu an Asus mobo (975x) for Conroe, but also be able to toss in a Kentsfield. Asus says their adjustable up to 450, but will it be STABLE at that FSB!!!

It's a 300$ purchase here in Canada, so I wanna be somewhat future proof!
 
People on xtremesystems.org forums have had Kentsfield Engineering Samples working 100% perfectly in the Asus P5W-DH Deluxe 975X board. I ordered mine in part because of that... it will work with Kentsfield :).
 
It will not be higher than 1066. The MCM design puts two loads on the FSB instead of one like a true dual-core CPU. If Intel can keep the bus speed the same, that would be great. However, I wouldn't count on it. Intel already stated that Clovertown's FSB will drop vs. Woodcrest. I don't know if Intel will do the same thing on the desktop side or not.

So it's more of a "dual-dual-core" than a "quad-core"?
 
expect 1066, as thats what the ES's are. Even though Kentsfield/Clovertown will surely need as much FSB as possible to keep 4 cores fed.

The current Woodcrest Xeons are 1333, so maybe the server version will be 1333.

Its just 2 of the current dies of Core2, slapped on one CPU,

kind of like Presler, but Presler is 2 x single core/cedarmills = dual core.
Where Kentsfield/Clovertown will be 2 x dual core/Conroe/Woodcrest = quad core.

I wouldn't be surprised if Intel pulls it out early (ie: beginning of quarter, not end as some are expecting) as its should basically be done, and not need a lot of testing. It works with current Core 2 chipsets. 975/965, and possibly 945/955 with the updated Core 2 VRM.
 
I wonder how well the FSB will OC. It looks like the folks at XS aren't having much luck with it. :(

Nope... all quad core CPUs at the moment (kentsfield and clovertown) are 1066 FSB. They may bump this up down the road, but I don't think so. Launch will certainly be at 1066 for both.

DAMN IT! That was a hopeful MAYBE! :(

Not that it really matters, as I won't be buying a Xeon.
