This Q6600 which is a LGA 775 Socket and it's FSB is 1066MHz: http://www.newegg.com/Product/Prod [...] 6819115017

My motherboard is a Abit 945P IL9 Pro. It supports 1066MHz FSB and it's socket type is LGA 775: http://www.motherboards.org/review [...] 680_2.html

The only conflicting thing is that almost anywhere I go that motherboard says it doesn't support Quad, yet it says it supports Duo.

So, the obvious, would this processor work with that motherboard? If it wouldn't, what would be the worst that could happen to the motherboard/processor? Is it possible for me to buy the processor and return it to let's say frys if it doesn't work? What is the best way to approach this?

Thanks for any help.

That board does not support quads or 1333 fsb, so Q6600 and Exx50 won't do. Some newegg reviewers got it to work with E4300, E6300 or E6400 (the E6400 is the best of these).
 
The E6400 is $200 at newegg, which is ridiculous. Keep in mind that board won't overclock.
 
I suggest getting a GA-P35-DS3L and a Q6600. It will cost you 375 instead of 200 but it would be much better IMO, especially with a bit of OCing.

^Agreed. Get a P35-DS3L or a P5K-x.

Not according to the official site
Since even the X6800 is not there, i assume it does not have enough power(3 phase voltage system) to run a quad....i also am not if the Intel 945P can even see a quad....

Could I just keep my motherboard and get a E6600? Could a E6600 work?

yes an e6600 will work as long as you have the latest bios....see the page i linked above....

But last i checked....as 6750 is cheaper...and faster

My motherboard only supports up to 1066MHz.

yes but the price difference may make another board worth it....better in the long run......

Well, as to the recommendations, I agree, but I am using a Q6600 on a IP35-E at home right now, but before I got that, I was using an IL9Pro and the Q6600 worked flawlessly. No booting issues, ran stable, would run games like a dream, at the time it was paired with a x1900GT but it still ran good

Oh and in response to getting the E6750, to my knowledge, you could run the 6750 on your current board, the IL9Pro, it will simply clock down the front side bus... I ran a 1066 bus core 2 on a 800mhz fsb MSI board and it worked fine. But other than that, cheers!

the clock down(1066 from 1333) would slow it down quite a bit tho....

good to hear a Q6600 worked....i am not sure why they did not just put it on the support list....maybe over time it could be bad for it....

Yeah, I'm not really sure if you should test your luck with it, it could very well be bad for it. I ran with it for about a week and a half til i got my IP35-E. Good board, just uhh hate the double boot shiz

Is IP35-Pro compatible w/ Corsair TWIN2X4096-6400C4DHX? Coz i'm planned to add the RAm module next month. I've search the link http://forum.abit-usa.com/showthread.php?t=124502, and the Corsair TWIN2X4096-6400C4DHX doesn't appear in the compatible list. Im using Q6600.

Oh... and thanks for the help.

There are users on other forums running that board and ram fine. Just do not disable quick post. There is a glitch on that board for more then 2 gigs of ram and quick post disabled.
 
Here are 2 other forums with users running that ram and board. As said...keep quick post on and you should be ok...
