Hi all, out of curiosity, I am wondering if OCin the i5 from current 3.6 to 4.0 will worth the performance in FSX.The spec I have now:i5 @ 3.6 Ghz4Ghz OCZ Gold DDR3-1600 (However, I'm running a 32b Vista)BFG 8800GT OC 512MBArctic Cooling Freezer 7 Pro Rev. 2 (load around 60C, ambient about 15C)

I think I would be happy with a nice stable 3.6 Ghz on the i5.

A faster CPU will generally translate to better performance in FSX (unless you have some other limiting factor, which I don't see in your config here). If you can get it there and keep it stable without tremendous cost, and without pushing components dangerously close to their design thermal or voltage boundaries, then why not at least try?Pushing my i7 from 3.3 to 4.4 GHz absolutely does make a difference in FSX performance, especially with a complex aircraft in a complex scenery area.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

The thing is I'm not sure a mere 400hz more will provide a much different result. My old E6750 OC from 2.66 to 3.1Ghz was just marginal, if even that, result.

I run my I7 at 4Ghz. I feel there is a difference at 4.0 vs slower speeds, and 4.0 was the "comfort spot" for me.It is more subtle than an X% increase in FPS. It may be less stutters in a complex setting, a more fluid experience at high density airports, etc. One thing I can do at 4.0 for instance is set cloud draw distance at max, giving me a horizon to horizon overcast below me when at the flight levels.Good luck.Joe

You could see FPS improvements in the 10% range, as application performance tends to increase linearly with CPU clock speed (excepting for other bottlenecks, of course).

Everyone is talking about an i7 at 4 Ghz. While I know the i5 can get there, is it stable enough? Of course it is also known that every processor off the assembly line is not the same.

I tried to get to 3.8 but it got really unstable unless I added more volt, that leads to higher temp., which I didn't want since I had a crappy case and the airflow sucks.However, I'm actually pretty pleased with 3.6 so I guess I'll just seattle with it for a while :)

:( I remember playing FS 98 on a 500 mhz processor and that was what I had upgraded too. Getting old sucks.

If you have really good CPU cooling and a well aired case, you should be ok to up the voltage and OC to 4GHz whilst keeping it stable.
