What Quad Core will work in this motherboard?

[Jolaine]

Hello,

What Quad Core will work in this motherboard?

P5N-E SLI. I checked the (outdated) QVL and it doesn't show much. Just a few. I was really wanting to use ""Intel Core 2 Quad Q8300 Yorkfield 2.5GHz LGA 775 95W Quad-Core Desktop Processor""

I've been to numerous forums looking for help

Hello and welcome to the forums
According to
http://www.asus.com/Product.aspx?P_ID=KyHOsOKWujC2QguJ&content=specifications
It supports all dual core 1333MHz FSB CPUs so it should handle Q8300 just fine.
I also found these links which confirms that it works

"I have installed Q9550 on P5N-E SLI after bios update to version 1301 and everything works fine (also processor speed at 2.83 GHz).
I didn't try to overclock cpu."
"I just put a Q955O ON MY P5N-e SLI with the 1403 Bios. It works fine but the core voltage is at 1.403 and I can't overclock anything, including ram. The CPU seems to run a little hot. Don't know if I need new motherboard."

Thank you for the reply, and I've also read those forums as well. The funny thing is, a moderator over on the Asus forums say the P5N-E Sli board doesn't properly handle the 45nm chips...

This is getting to be quite the headache...

Strange,because there are no logical reasons that it doesn't work fine(with the latest BIOS)

Right, however according to the link you gave regarding all core2quad 45nm processors - on the Supported CPU List, it only lists 4. the 6xxx series.

So this is definitely frustrating for me. For reference:

"The board can't support 45nm quad core processors... that is generally a voltage regulation circuit issue."
hmm,So it should work fine but you it may lead to a circuit issue,so keep away from them IMO.Better be safe than sorry.Get a Q6600 with G0 stepping instead.It's a great OC'er too.

Q6600's are becoming more rare and very pricey. But yes, that seems like the only option, unless I get a cheaper E series 2duo
