Hi everyoneHave been slowly getting a handle on my system and have a question or two about heat and the i7 975 processor. I downloaded OCCT and ran a stress test on the cpu and found the cpu temps climbed to almost 80C in about 5 minutes. I decided to kill the test at that stage. I must point out that I have not overclocked the system yet.Do the temps that relate to this OCCT test also relate to what is likely to be happening while FSX is running?I have the cpu on a ASUS P6T deluxe V2 mb and there is a large fan that sits over the top of the cpu obviously trying to keep the heat down. Is this doing a really poor job of cooling the processor or do I now need to look at some other method. I certainly didnt want to go down the water cooled route unless aboslutely necessary.Can I overclock this machine at this stage or do I have problems, if so what do you suggest?I look forward to your thoughts.Tim

If you use a multiplier of 30 across all four cores, that will get you to 4.0 GHz. At that overclock, on a good air-cool solution, you should see no greater temps than 65 C on any of the cores. You will be fine. That is the hottest it gets on my 975 at 4.011 GHz, while running FSX. You usually run between 45-65 C while flying.

Hi MitchWill be getting an aftermarket cpu cooler tomorrow. Are there particular brands and models I should be looking for, obviously the bigger the more heat I will get rid of.Also I intend to use TurboV to OC and dont really think there is a lot of need to push beyond 4gig. Would you mind giving me your OC settings as we have similar set ups to try for my OC since you are so happy with how you are going. Should I start with my settings a little lower just to be on the safe side?Many thanksTim

----------------------------------------------------------------------Hi Barra,I can't really recommend an after-market cooler, as the 730x's standard solution is pretty much equal to an aftermarket affair. On the overclock, please check out my posts on this forum as I have answered a couple of them with a detailed run-down on what I did, to get to 4.011 GHz. Yes, I am most satisfied with staying at 4.011 GHz as it gives me great FSX performance and keeps the temps (air cool) at what I posted to you...and very much below anything you'd need to worry about. :) Enjoy your system! What's nice about the i7-965 and 975, is that you ONLY need to raise your multiplier...and not have to mess with any other clock component of your system. Because of that, I could bump up my stock RAM to 1300 MHz at pretty aggressive timings and have them extremely stable. They do the trick! :)Cheers!

Hi MitchI did try just bumping the multiplier but got some rather nasty stuttering outside the cockpit in the other view modes and even had a/c disappear with only a few part of it visable. I put it down to not enough voltage and other settings?Chhers Tim

Hopefully Tim, somebody with your board and BIOS (or knowledge of it) will offer you what they did to run stable at 4.0 GHz. 4.0 GHz does seem to be the sweet-spot that most people are striving for. At that speed, I can usually maintain 24 FPS with everything cranked full open on Scenery and Weather, but BLOOM which is off I know what I did on my system and BIOS, but would be hesitant to direct you on something that might cause damage to YOUR system. We are typing here about a $1000.00 plus CPU! Good luck in what you do to get to the 4.0 range! :)Mitch
