Overclocking

Posted by: MJB

Q9540 Overclocks easily using stock voltages and cooling to 3.2GHz and will reach 3.6 on air with no problems.

Overclocking is limited by the motherboard in most cases and will top out with a FSB of around 470MHz (3.76GHz) on most current P35,x38 and x48 boards

the PDN for this product starting in november 2008 and will phase out between the first and
second quarters next year

Overclocking Continued

I agree with the previous comment about overclocking. I had three high-priced system builds and tried a total of eight different motherboards and six different coolers. The Gigabyte EP45-DS3R with Xigmatek HDT-S1283 could just barely hit 4GHz and stay stable on Mersenne Prime in each instance. Chipset makes a great deal of difference between motherboards. It's also good to keep in mind that a Q9450 at 4GHz far exceeds the performance of any currently (2009-07-10) available i7 processors.
