I have a P5W DH Deluxe (1.04G / 2901 BIOS) with Core 2 Duo (6400) CPU.
4x1Gb Kingston PC2-5300 RAM (CL5). BIOS default configuration.

I would like to upgrade to a Quad core because I need the extra cores, and preferably also higher frequency.

The compatibility matrix for the board clearly states that several 45nm Quad cores CPU's are supported, but we all know how much help I'm going to get from ASUS if something doesn't work :-)


So I'm looking for someone to confirm that some of the CPU's I'm looking to upgrade to are not only supported but also work! I don't Overclock so standard performance (with standard cooler) is fine by me.
Also since I don't understand much of FSB (board is 1066MHz max I think, anjd Quad cores CPU's are 1333MHz, does it just clock down or will BIOS now support ?)

Does anyone have any experience/problems/suggestions, perhaps these (which I can buy cheap)?
- Core 2 Quad Q9550 12 MB (Intel Boxed)
- Core 2 Quad Q6600/Q6700
- Something you had working ?

Both are on the ASUS compatibility list, and the Q9550 seems like the best choice (and cheaper than Q6600), but the Q6600 as I understand is 1066MHz/non-45nm and might be a better match?

I am looking for the most stable upgrade (that works with my RAM), speed is secondary :-)

PS, I have been looking through this thread, and there are a LOT of posts and all of you are OC'ing some of these CPU's, but its difficult for me to see if I can do this without a complex OC setup/cooling/BIOS config.
