Will the new 45nm C2D cpu's work in older motherboards then the p35 ??

As title.....Is there any news on if the new 45nm C2D cpu's will work in motherboards that are not the new p35 board...like my 680i board ???

does anyone know about the 650i boards like asus p5n-e

I believe so as they support the 1333fsb and are slightly cut down versions, but not 100%, can anyone else shed some light?
 
I thought I had read that anything with 4/5+ phase voltage regulation would work? Was hoping that my DS3P with 6 phase would work.

Will these 45nm C2D's be faster? or just run cooler and use less energy and possibly overclock more?

I read somewhere that Intel are going back to processor redesign 1 year and die shrink the next year. Going by that they should just be cooler and overclock more - probably got more transister real estate so massive cache I'd assume.

That said I've not been around in the hardware world very long so maybe someone who's been the the game a little longer could provide a better answer.
 
I think the idea is with the 45nm process they will produce less heat, and hence be more receptive to higher clock speeds.

If you look at the temps the quad cores are currently running at, much over 3GHz seems to need water cooling. If the heat keeps going up then the CPUs will have to have lower clock speeds as the number of cores increase, if they are to be sold with basic retail heat sinks. 45nm should solve this heat escalation problem.

That's how I see it anyway.

The P5N-E Will indded support Penryn!

1333 FSB!

I dont think that just cause the motherboard supports 1333 fsb, that it will support Penryn. The Gigabyte S3/DS3 series support 1333 fsb, but will not work with Penryn because of the different voltage requirements. I think that all current LGA775 motherboards (bar the 680i if it does support it) will not support Penryn because it does not meet the minimum requirements for the cpu itself.

This is just what i think and have read, but i do hope that my DS3 will support Penryn since its Rev 3.3 and natively supports 1333fsb.

Pretty much spot on there mate, this is why i held off the quad, 3ghz is a big downgrade for me and I can't see me benefiting massively atm with Quad. :)
