In the endless quest for more performance in FSX I choose to start over-clocking my CPU, an AMD Phenom x6 1055t.The test bed:CPU: AMD Phenom x6 1055tMotherboard: MSI 870-G54ARAM: 4GBPSU: 650WGPU: MSI Cyclone nVidia GTX460 768MBThe stock clock on the 1055t is 2.8GHz, so with a Cooler Master Hyper 212 plus, I've over-clocked it conservatively to 3.5Ghz. So far I'm running an avg. temp of 22C while flying over FTX's Sydney scenery at full density after 15 minutes of ground and flight time. My result from flying from Sydney to Perth I saw a peak temp of 25.2C, not to bad. Apart from making sure I'm not cooking my CPU to get higher FPS, I was looking at my FPS over Sydney. I usually got a choppy 11 avg. That was tolerable, but choppy. After my over-clock I noticed only an avg fps increase up to about 13~14, but what really changed was the smoothness. The FPS didn't go up dramatically, but it did smooth it out. I've read in some tuning guide that mentioned how low FPS won't really mean you will have a choppy experience. I think this is what I'm seeing now.I'm going to step up to 3.7GHz and then try 3.8Ghz with more votage, but I'm getting told by my the MSI board that a CPU voltage of 1.4v+ is not recommended. My suspicion is that it might be because of my power supply not be an high enough wattage.I will also see how my performance will increase at Heathrow, Charles de'Gaulle, and O'Hare. I'm choosing these because they are generally big FPS killers and because I have after market sceneries for them.I'll report my experience later :)

I overclocked up to 3.8Ghz over the night tested again over Sydney, but this time I used a PMDG 747-8 instead of the Captain Sim 767 from before. I noticed about an overall 3 FPS increase, but I was still staying below 20 FPS while flying at 2000ft around the city.The more I climbed to my cruise alt of FL300 I was much higher FPS over 30.I still have the other airports to test at. So far still pleased with the forward progress and only a few degrees more on my CPU temp thanks to the cooler.More to come.

You should try and maintain a similar test when overclocking. Since the 748 is using same cockpit/VC as the 744, I know that these are much less fps intense than CS products which like to eat frames with their eye candy. Pick one or the other, just so we can get a rough idea of how overclocking increments effect performance.

I understand, my habit of switching around didn't do well for my test case. Let me try again me with a more scientific way and make the CPU clock the only variable. :Thinking:
