Hello,A question, my I7 920 2.67 GHZ, turbo charge on running at 2.8GHZ with a P6T mobo and coolermaster v8. ambient temp is approx 20Cand my RealTemp indicates these temps: 44 42 45 42 are these too high?? Used OCCT for an hour and no error was reported.If these temps are too high I will hold off with overclockHelmut

Hi Helmut,I have an I7 975 and I'm overclocked to 4.14GHz. My temps hover around 64 and I do not see this as a problem. 45 gives you room for an overclock. I'm rather conservative, and rightfully so with an $1,100.00 chip, so I stopped at 64 degrees.I don't see any reason why you cannot overclock that chip.

Hi,Thanks for the reply, just did a short flight with the PMDG MD-11, Rex weather. my temps were 55 51 54 52, I hope this willleave some room for an overclock however the hot days are still to come, I live in Canada. I am also new tothe I7 and overclock.Helmut

If you are using the stock cooler (and plan on overclocking) I recommend buying a better aftermarket cooler, like this one:http://www.crazypc.com/products/ultra-120-1366-50985.html

I have the Coolermaster V8 installed when I upgraded to the I7.Thanks

if you are new to OC, All you need to do is increase the BLCK speed in Bios, and leave everything else on auto.BLCK is that number that will currently be about 150 in your bios, mine is now set to 185 which gives 3.8Ghz on my i7920 system.I am on defualt cooling, if you are using v8, i suspect your system will be even able to go faster than mine, maybe 190 to 200.And I dont care what anybody says, i always test my OC with FSx and not Prome95 cause FSX is less demanding than prime95, and an OC that is stable for FSX can still crash under prime95.My current 3.8Ghz oc crashes under prime95, but has not crashed once in FSX due to the OC.So if you wana keep it simple just change the Bus Speed only. If you wana play it safe increase it by 10 each time then test with an FSX flight in cruise phase, and make sure to use 16x time acceleration to do the test.FSX Time accleration makes the cpu get hotter cause it works harder. Or PMDG with 8x will also do, PMDG Autopilot does nto work for 16x.When your bus speed reaches 180 in the tests, i strongly recomend you increase it only by 5 each time as you test....180..185...190...195..200...200 gives you justabove 4 Ghz speed.yeh since i have HT on my temps are about 66Cwithout HT about 58CBut never use HT and affinityMask of 255, i have no affinitymask entry in my fsx.cfg, which means even thjough HT is on, its only used by vista not FSX.i get smoother flights with HT on, but higher temps too, however if you should allow FSX to use HT by setting 255, then the temps will probably blow my PC running on air at 3.8GHz i7920.

This was quite a change from before the overclock.Always had performance problems flying into jfkI will move to 3.4 GHZ in due time, one step at a time, also will try to change some of the other BIOS parms as I feelcomfortable.Much appreciated
