Testing & Overclocking:

   I ran a bunch of tests running the E6400 at it's stock 2.13GHz and my memory at the rated 800MHz @ 4-4-3-8 @ 1.8v. Then I went on an overclocking frenzy and Re-ran the same tests running 3.6GHz and my memory at DDR2-900.

   I was able to take this E6400 to an amazing 3.6GHz, totally stable and on AIR cooling using a Zalman CNPS9500. What's more amazing is this test setup is in my modded tech station and there are no fans blowing over the hardware. It's just an open air system with nothing blowing on anything other than the CPU cooler.

   Utilizing 1.5v in the BIOS for CPU voltage I was able to completely stabilize 3.6GHz by running two installations of Prime95, saturating both cores to 100%, for a duration of 12 hours. Not a single error, but I will say that it wasn't running cool! LOL! After 12hours of 'double' Prime95, I had an average full load temp of 79c! Crazy high? Yes. However overclocking a 2.13Ghz all the way to 3.6GHz on air alone is not for faint of heart. Let's take a look at the stock vs. overclocked benchmarks...

Results:

PCMark05 2.13GHz	PCMark05 3.6GHz
3DMark05 2.13GHz	3DMark05 3.6GHz
3DMark06 2.13GHz	3DMark06 3.6GHz

SiSoft Sandra 2007 Synthetic Benchmarks
 

   The one benchmark that really stands out to me is the Sandra CPU Multimedia benchmark. Even at stock, it crushes the competition, but check out the 3.6Ghz bench! OMFG! I also ran other speeds in-between 2.13Ghz and 3.6Ghz and ran some tests, but I'll save those for my upcoming overclocking article :)
