April 28, 201016 yr Great, thanks :(I have to try that too. My overclock is just 3.8 Ghz. Can you tell me if this 400Mh extra do a lot for FSX?Allard.

April 28, 201016 yr Author Great, thanks :(I have to try that too. My overclock is just 3.8 Ghz. Can you tell me if this 400Mh extra do a lot for FSX?Allard.I don't know as I went straight from 2.66 to 4.0, then 4.2Ghz. 400Mhz is a pretty decent increase in processor speed, 3.8 to 4.0 most likely won't make much of a difference. I think anything in the 3.8 to 4.2 range with FSX and an i7 is a good range to be in, but if you can get more speed while keeping load temps within reason, and maintain stability, I say go for it.EDIT: I made a mistake in the original post, the IOH Voltage is 1.36, not 1.32.

April 30, 201016 yr Author Thanks for posting! Please see if you can edit your original post to correct the IOH Voltage.Cheers,- jahman.No problem, I'm at 4.3Ghz now and leaving it be. The edit option is long gone. Shane Gavin
