Presler has arrived so I must stop and ask: where the heck is Cedar Mill? :mad:
 
I believe the 6x1 series are all out, and retail... at least in Toronto they seem to be.
 
are there any benches for Cedar Mill? How is it different from Presler? Is it compatible with older mobos?
 
The link above shows the 631 on froogle, TD and PC Connection. I also see the 641/651/661 on froogle.

No idea on its compatibility, but I'm sure anything above 945 will work fine. I don't have any benches for you (I'm sure you can google them or have someone here post them)... From what I remember reading, the Cedar Mill is just a single core version of the Presler with HT enabled. And if the Presler is any indication, these things will overclock like mad on air, and generally be cooler/faster than their older generation 90nm cousins.

thanks for the info.. I just e-mail intel about compatibility with the 7221 chipset (I want to upgrade my SC420)
 
Cedar Mill is compatible with 910 and higher chipsets, as long as the BIOS supports 6xx CPUs.

My guess is that the SC420 won't support any 6xx processors since Dell never sold any with 6xx processors. The two I bought had P4 551 processors. The A01 BIOS (7/2005) update has this listed: "7. Added support for newer CPUs" so I may be wrong about 6x0 support. That date is a few months after the 6x0 processors were released. The strange thing is that I can't find anyone who even attempted to upgrade a SC420 with a 6xx processor on Delltalk or google.

The 945 and higher chipsets had to deal with more than just a new core. It also had to perform some of the dual core communications (shared memory accesses, cache communication, etc).

The E7221 chipset is the server version of the 915G chipset (minus the 3D portion of the northbridge).

Thanks for the detailed information. I guess it's time for me to be the first one to try in the near term?
