Intel Xeon X3440 

Released September, 2009
  • 2.53 GHz
  • Quad core
5.1 Out of 10

I would recommend this little CPU to anyone who still has the 1156 socket server board or anyone who has an H55 chipset.

Made it to 3.3GHz for what it was worth.

Reviews Word on the street for the Intel Xeon X3440


9.6
The 95w TDP let me cool it with stock cooling for most of the time that I had it; games only made it up to around 59-60*C at stock.

What People Are Saying Give it to me straight

Clock

Overclocked mine for a short time before I realized that the clock increase didn't yield any real gains.
by Imglidinhere (Nov, 2011)
Extremely powerful for it's low clock speed.
by Imglidinhere (Nov, 2011)

Applications

I found mine on the cheap from a local CPU retailer who was going out of business.
