You will probably be motherboard limited. The Q9300's clock really well from what I have seen.

My q9300 runs at 400fsb (3Ghz) without even upping the voltage. I haven't tried any higher really, quiet 3Ghz is very nice thank you
You mean you haven't manually increased the voltage - your motherboard is probably doing it for you. The default value is called [AUTO] for a reason. You may be horrified to discover how much extra volts your motherboard is applying on your behalf.

No, I meant what I meant. I use manual voltages. The 'auto' mode tries 1.3V and I changed that down. Only upped the voltage a bit on the RAM and chipset (+ .1V)

If you have good cooling you may find you can push the CPU further without sacrificing its life span. Saying that CPU's will last for years even if they’re running just shy of their throttle point. A combination of heat and high voltage can kill chips pretty fast though.

I'm having a frigging nightmare getting this Q9450 Prime95 stable at 3.8ghz in my IP35 Pro.
It's pretty much on the chips FSB limit in this particular board (475mhz). Managed 8 hours once but she froze as I was lining up the screenshot. Has been happily folding at 3.75ghz overnight every night since Sunday.

I'm not surprised Cob. They are fine up to a point then just stop. I tried Water and phase to no avail, wouldn't budge at all.

470MHz is no mean feat though!!
Better chipset cooling and more juice would probably get you to 3.8GHz but probably not worth the effort.

Chipset cooling's grand...
More juice has no effect atm. Tho I haven't really any more options left to me to give it more.

Fair enough.
I think your cooling efforts have given you an edge though, as ip35 pro's tend to max out at 450 with these chips.

I only ran a quick Folding benchmark on Saturday morning. With both chips at 2.66ghz (333x8) the Q945 was about 9% faster than the Q6600. Tho that was with pretty cache-light units, and Folding isn't yet optimised for SSE4.1. I'll run some more comparisons tomorrow or Saturday. List any benchmarks you'd like run on the 2 chips.

Hmmmm how did you attach your additional fans since I have same board and doing my build this weekend!
I am having this problem too. Have mine at 3.6ghz completely stable but any higher on the FSB it will suffer random freezes whether 1 hour of prime or up to 6 hours but it always happens. What chipset voltages are you using for 475 fsb mate?
Soldato
They're all plugged into the board. The IP35-Pro has six fan headers.
Soldato
1.52v MCH/Northbridge and 1.32 VTT/FSB. The southbridge voltages are on the second lowest setting.
Tho I needed to tweak the GTLRef's too to get this far.
