I know that FSX is extremely CPU intensive. So, if that is true, would playing an hour of it at high settings be a good stress test? I just got a 20% overclock (holy !@#king !@#t) on my notebook, so I wanted to make sure it is stable. This would not be a permanent OC, I would just apply it when playing FSX. I don't want to shorted the lifespan even more than it would be. What do you think? I'm running an Intel Core 2 Duo P8700 at 3028.9 mhz. Is this pressing it too hard? It wouldn't be permanent...

THIS IS AWESOME!!!

No.

FSX doesn't balance all cores correctly.

Run OCCT one hour test.

3000mhz is not pushing it very far although it depends on how many volts are running through it. I could underclock my processor and still fry it in a few days if I pump enough volts through it. as always minimize the volts.

my processor has a 25% overclock for two years, no problems so far.

Sorry, but I'm kind of a n00b to overclocking. I used calculator to find 120% of 266.0 which was what my FSB was. I plugged the number into SetFSB, and it worked. I will run an OCCT test soon. It seems stable, but how can I tell my voltage? Here is the the setFSB window:. Is this bad?

Edit: Temps measured by speedfan got up to 75 degrees C within 3 min of starting the test, that scared me and I canceled the burn. I will pick up a laptop cool-pad in a few hours and then will re-attempt. It NEVER gets this hot in ANY game. Crysis, MW2, FSX, NFS UC, never. What would the max temp be? Max outside operating temp is 105 farenheit. I heard that 80 Celsius is the end of the line for any processor. 15% OC gets a steady 70 Celcius in OCCT. Is the 20% unsafe?

Edit #2: I did the stress test under close supervision. It passed... Temp kept going up to 77 and then back down to 72. I think it's safe. Thanks, guys.

I called Alienware support earlier about a non-related problem and happened to mention some graphics anomalies. The tech downloaded OCCT and ran a stress test on my ATI 5970 because he thought there might be a problem. The test crashed it, twice. He said the card was bad and is sending me a new one. During the test and before the crash, I noticed the temps get up into the fifties and sixties and asked him about it, since it normally runs 29 to 31, even when running FSX. He said no problem as long as it doesn't go over 85.

Also, my factory oc Aurora was 2.66 oc'd to 3.2. I believe that is 20% and it was done by Alienware.

If God intended aircraft engines to have horizontally opposed engines, Pratt and Whitney would have made them that way.

Around 70 is the maximum you want for day to day use.

Also graphics cards handle heat better than CPU's for some reason. My card gets up to 90 during Furmark.

It's fine. Temps never get above 60 when gaming, ever. I think it's good. My GPU is another story, 85 is not uncommon in Crysis. Furmark got it to 100 once, but that was when I left it on the floor with the test. Laptop innards should probably never be above about 90, but my fan kicks on 'uber mode' at that temp. It will wake up everyone in the house. I think I'm good. Thanks, everyone.
