HiI've done a short run with HT off. Note that these are calibrated readings shown in Realtemp. You would need to add 3 C to get an uncalibrated reading.I did run at 5Ghz for a while some time ago but the difference in FSX is almost invisible. From my notes, temperature was 74C calibrated (77 C uncalibrated) with volts in offset mode of 1.448 to 1.456.You will probably gain more by O/C your GPU to say 850 to 870. No need to raise the volts.

Thanx Howard!

I would like to see anybody's air cooler beat this. H100 is now official.MSRPH80: $109H100: $119

Thanx Howard!

No Problem! I just noticed that here https://spreadsheets.google.com/ccc?key=0AuiXjW8fJyDrdC1KZm5fSlJYdnJBaXRRclFuU0U3WUE&hl=en&authkey=CMSSocoI#gid=0 it says you have a 580 but your sig says 560Ti.

Hi Howard-I had both the 560ti and the 580 in the house together for a few days. The 560ti won the contract. <g>

What´s actually going on here?People run Prime 95 with "low" clock, and everything is fine and dandy, and then fire up FSX with 5.0 Ghz!Please, Spiritflyer, let´s have a look at prime 95 with 5.0 Ghz, I bet the temps will look just a little bit different.

I have to quote meself, since nobody care to answer!Why run Prime95 test at 4.6 Ghz, everythings fine, and then load FSX with 5.0 GHz???Am I stoopid, did I miss some important "Holy Grail" FSX Agenda/Rule, or what?

Pushing your rig with Prime95 at 5.0GHz will probably raise your temp to the unsafe zone compare to the temp reached running FSX unless you have a custom mader water cooling setup, so what some of them do is to find the highest stable GHz on their rig keeping the temp in the safe zone and try to see if FSX will run on higher GHz without testing with Prime95 as they already know that the temp will not be raised as high with a CPU at 5.0GHz using FSX as it will with Prime95.I use OCCT for testing stability as it does not pushed a PC as hard as Prime95, unless you are trying to reach the highest stable GHz with Prime95 for bragging right I can't see when you will push your rig as far as Prime95 does in a regular 24/7 use. Here are my temps after one hours of testing with OCCT at 4.510Ghz with SIX core, I did not saved the OCCT test at 4.677GHzHere is a SuperPi test done at 4.67GHz

Yep. FSX, with moderate to high settings, at 5.0GHz uses less energy than a 4 core Prime test at 4.6ghz. In fact, a 4 core Prime test at 5.0 uses roughly the same amount of energy as FSX at 5.4GHz.BTW, for you haters out there ----I'm running at a new 5.0 volt setting: offset at -10. uh huh - under 1.40v. Been running the setting since yesterday. Did a Prime95 2 core test that rocked between 1.382 to 1.396 (FSX uses 'bout the same amount of energy as a Prime95 2 core test).For those that are interested: The .15 volts off my previous volt setting means about 2c.

I wonder what Corsair Link Commander is... That 100 would fit nicely in my 650D :Big Grin:But I believe my mobo isn't letting me get any higher than 4GHz so I'll have to wait for the component upgrade, another year at least before I spend more.

Thanks alainneedle1, Iearned something, again..!

For 5GHz I need 1.42V or something. Too much for me, but temps are perfectly fine on air under prime. Never hits 80ºC in the hottest core. It's a 95W TDP chip after all.Hope you learned something PFL

Hmmm... Not sure what your point is? Too bad we don´t have him over here anymore, cause there´s too much guessing and fiddling-hoopla going on here IMO...http://www.simforums.com/forums/building-dedicated-computer-need-some-advice_topic39136.htmlFried Chips anyone?!

Temps are fine at 5GHz. Volts are more than likely too high though and I would never run my 32nm chip like Alain or Ken do on air for just 200MHz, but that's just me

Dazz, as you probably know Intel is giving an absolute voltage for all CPU, does that mean that if you go over the absolute voltage you'll fry your CPU, maybe and maybe not, Intel is playing safe (warranty).You could not belived what voltage I was running my Q9650 at, it ran for over 2 years at voltage well over the absolute max from Intel, I still have it. I fried a QX6850 ($1,000.00) 4 years ago but not because of voltage but more because of my own stupidity.I get no joy out of frying a CPU just to see how far I can push it, everybody can do that, but I enjoy to see how far I can push it with little adjustment here and there without frying it.I can ear you all saying "Well at this kind of voltage your CPU will not last more than 2 years if your lucky" guess what, in 2 years it will be time for a new and up to date one, in the mean time I'll get my money worth out of this $1,000.00 CPU I have one golden rule about overclocking, here it is, "If you can't afford to overclock don't"...:Peace:

He-he!I like your attitude alainneedle1, and BTW I just changed the thermalpaste on my CPU, from "Geled -something.. " - to "Tuniq TX 4" - and the temps dropped 4 degrees C.!Did a very thin layer, not the blob in the middle, no, no - just a thin layer all over the CPU....... on the way to 5.0 Ghz!
