Congrats on this overclocking!

The highest speed I have reached with this CPU is 3.515MHz stable using my Thermaltake TMG i1 air CPU cooler.

Stress Testing with Prime95 my temps got to 65°C (Real Temp) on both cores.

How did you stress test your system?
What are your temps during stress test?
Have you tested using OCCT 3.0 (it now has the Linpack test, which is the same as IntelBurnTest)

i used an older version of occt. I will run the new one on my ssystem tonight and post my results. I have seen the temps hit 65 ONCE for about 1 second and drop down to ~50-55

If you haven't used the OCCT linpack test or Intelburntest previously at this speed, I will advise to be cautious.

Maybe you can run one OCCT "Normal CPU test" and see your temps using "Real Temp" or "Core Temp". If it is ok with the normal test, then try with the Linpack test. This Linpack test really tests your cooling...

Thanks for the heads up

cpu wouldn't post without voltage that high. I am thinking about getting a different mobo and PSU to see if i can't change a couple things

I want to see a screenshot of 12+ hours of Prime95. Then the 4 ghz overclock will be more believable.

The highest I could get my E7200 with Intel's stock fan was 3.24 GHz (340 x 9.5) with 1.312V Vcore. Core temps during stress test got to 71°C & 70°C, as reported by Speedfan, which I know now is reporting about 5°C higher than RealTemp.

I tested it stable with 6h Prime95, 2h OCCT, 14h Memtest86+.
