Will they be able to be put in a Gigabyte DS3 or will a whole new mobo be needed because if the Yorkfields can be put in a gigabyte DS3,then i'll get that instead.

The best answer anyone outside of Intel can give you right now as to whether it will be compatible is "probably not."

i got a asrock board that takes agp and ddr/ddr2 because i'm waiting for gigabytes p35 board....which could be sooner than i first thought...


Bearlake (p35, g33) will be 45nm compatible

there were no VRM tweaks. Only a BIOS update.
If he has DS3 Rev. 3, which natively supports FSB1333, than he'll need to update the BIOS inorder to use a Penryn CPU.

Mine is Rev. 2 and does nt support FSB1333 natively. It would be nice if it can support Penryn.

I have to agree with Jack on this one. The board had an updated VRM.

Can't find it? It's under that blue heatsink

The processors were plugged into a modified Intel BadAxe2 motherboard, with the modification being necessary to support Penryn. Each system had 2GB of DDR2-800 memory and a GeForce 8800 GTX. All of our tests were run under Windows XP



So I tend to *think* you will need an updated board, but I am guessing. Hopefully my RD600 might work... my voltages go from ~1v to ~2v lol.

Finally, with regards to motherboard support, Intel isn’t making any guarantees about Penryn’s backwards compatibility. While Penryn will still use the LGA-775 socket that Prescott and Conroe have used, motherboard support will require more than just the presence of the socket. If the appropriate VRM spec is implemented, then Penryn will work on your LGA-775 motherboard, the problem is that motherboard manufacturers haven’t yet released information on which of their boards will support the Penryn VRM changes. If history repeats itself, you can expect very limited official support for Penryn in currently shipping motherboards and guaranteed support with boards based on Intel’s new 3 series chipsets (e.g. P35). We did see Penryn up and running on an Intel BadAxe2 board, but it had a hardware VRM modification done to it in order to properly support Penryn. Penryn may also be able to work on boards without a VRM mod, however at increased (potentially out-of-spec) voltage settings.



According to an Intel guy, there were no VRM modifications, but only a BIOS update. The newer VRM, found on the P35 mainboards will improve power savings, but it is not necessary to run Penryn.

But like you said, without Intel official word, we can't count on our older boards.

Interesting. I didn't remember reading the part about them seeing a Penryn on a stock Bad Axe. :oops:

Odds look pretty good for my RD600 then... now if they could only remove the BIOS imposed limitation of 511 FSB.

Thanks!

Unless Intel offically says the penryns will be compatible with current mobo's i'm going AMD
