Problems with P3d version 2.3 after overclocking

Recommended Posts

I am thrilled with version 2.3. I waa consistently getting 25 to 30 fps with PMDG 737, FIX global and vector, REX 4, tractoR, and Ezdoc. I built a computer with the I 4770 chip and Asus z87 MaximumExtreme VI motherboard to overclock. After four months I finally had the courage to overclock. I got up to about 4.6 before my problems began. Unhappy with results I reset everything to auto. Now I am having all sorts of problems running P3d. None of these appeared before attempting to overclock. P3D pauses for no reason in flight or will just freeze for a few seconds then unfreeze on its own. It takes longer to load and when shutting down I often get a fatal error. Track I.E. will work sometimes but not consistently even with both infrared lights on. Ezdoc sometimes appears on the add-on window and sometimes not. Since everything worked before I am assuming my problems are related to the overclock. I am wondering if these problems are related to my operating system. Should I reload windows? Has anyone else ever had this problem? If so how did you fix it? I don't believe I damaged my CPU as I have water cooling and my temps never got up but a few degree. Thanks for any help.

Maybe better to look at a forum for OC for your CPU with your motherboard. You may get more information there. I hope you didn't kill anything.

I think equipment is fine. The reason I think it was the operating system is when it failedto reboot and I lowered my settings for overclocking when it did reboot all the screens that came up gave instruction about the operating system.

Did you try a clear cmos on your motherboard? Did you stress test after your overclock, what did your CPU temps get up to?

This round I went the route of a full clean swipe of both my OS drive and my P3D drive.  Had the OS in there patching for nearly 4 years and P3D since v1.4, so I figured it was time.  I would suggest the same... if you have the time:

 

31 man-hours so far re-installing OS + 120 programs, apps, utilities, tools!  And that is not including any scenery or aircraft add-ons which is probably in the 100's.   But I can say I've got the quickest and smoothest OS and flight simulator I have ever encountered so for me it was worth it.

Temps never got above 30 c. I have quit overclocking and set everything back to defaults. The problems I am having started showing up more after overclocking not during.


Clutch cargo. I think that's what I will do too. It won't take too long as I don't have as many programs as you. Do I need to do anything like dragging or anything else prior to reloading software.?

hmm....I am overclocking successfully with almost identical CPU and board running 2.3...

 

After I tweak multipliers and BIOS settings I usually clear my prepared.cfg and let it build again...Maybe you can try this? Also at the same time this sounds like symptoms of a unstable clock...Im on a 4790k with the z97-ar and choose not to get passed 4.5/6Ghz

Re-installing software onto a pc that has unstable cpu/memory clock settings, is asking for even more trouble. Even setting the bios to default may not give you a stable platform. You should stress test your cpu and your ram, making sure it doesn't return any errors. For the cpu testing you can use progs like intel burn test, or prime95, my favourite. For the memory test, I highly recommend using Memtest86+. (the usb version)

Yes it did happen above 4.6. It seemed fine at 4.4, 4.5 and 4.6. As t 4.7 it wouldn't reboot. I got concerned when I dropped back to 4.4 and had a fatal error when closing p3d. That's when I set everything back to defaults.

If you got a 4770k to run at 4.6Ghz @ 30 degrees you must have some amazing cooling.  Can someone else back me up here?  I have a 4670k with an H100i and would be around 70-85 degrees with the voltage necessary to reach 4.6Ghz.

ya at 4.6 and 30 degrees it doesn't really seem right....That cooling would be un-real

 

Im with the h100i and a 4790k at 4.6 and im around 80 to mid 80's depending on scenery etc etc...

What voltage did it take for u to get 4.6

 

It took me somewhere around 1.28v if I remember correctly; however, it could vary significantly depending on whether you have a "golden" chip.  I definitely don't have a good chip as I struggle to keep 4.4GHz stable.  I use 4.0GHz for my 24/7 clock.

 

I tend to lean towards gogol's post in that you were probably experiencing thermal throttling during your overclock. If you have tried to run P3D on completely stock frequencies and voltage since then and still have issues then you may have damaged hardware. Even a moderate overclock without adequate cooling may lead to thermal throttling. I would definitely recommend stress testing your cpu and memory at stock clocks without turbo boost on, 3.5Ghz and run MemTest 86+ to rule out hardware damage. If all that passes and you have tried to reinstall P3D with no success then you can proceed with the day or so it will take to reinstall your OS and programs.  I would also reset my bios to default settings and do a clear cmos.

 

Good luck,

Ryan

OP: How did you overclock?

 

Did you do it manually, or use the motherboard's OC ability (if any)

 

Also P3D, like FSX, doesn't seem to like heavy overclock's. Do you by chance have issues with anything else?

Well I think it was 1.5. I am in the process of testing using soda 64. I am not using my temp gauges on my computer but the ones aida provides. Obviously my gauges aren't worth a damn as I get readings on the cpu of 29 where aida shows 60s and 70s

At 1.5v you would have most certainly experienced thermal throttling and a high chance you fried your chip.

1.5v on a Haswell and then running stress tests? Oh man, people really love to burn money as it seems. Why does everybody who does not have a clue wants to get into overclocking? Just don't do it if you don't know what you are doing. Overclocking Haswell is not easy. You cannot just use some presets in the BIOS. Leave it at stock speeds unless you really know what to do.

 

In your case: If you really applied a VCore of 1.5v to the chip and then ran stress-tests, there is a significant probability that you damaged the CPU. Another possibility why you are getting those errors even after resetting the system to default values is, that Windows might have performed some updates which were installed incorrectly due to the unstable overclock and are now giving you troubles. Reinstall Windows (at default speeds, no overclocking) and then reinstall Prepar3d. If your problems are gone then you were lucky. If not, you have probably damaged the CPU.

That is why I waited so long to overclock. Ok I am stress testing my Haswell at 4.4 with a voltage of 1.3. 10 minutes into testing and no throttling and no temps over 83. How long should I run this test and what is the maximum voltage I can go up to? If I don't have excessive temps and experience no throttling for an hour is it still possible I damaged my cpu?


Carlitto777,

 

While I understand your point I don't think I am entirely clueless. This is my second computer build and I researched a lot before I attempted to overclock. The problem is there isn't a lot of clear information on how to overclock. I saw a ASUS videon on the haswell i4770 chip with the asus z87 motherboard and tried to follow there instron. I don't remember anything telling you a limit of where to set the voltage. At 4.4 at 1.3 volts I have not experienced any throttling and temps are all below 86. I am hoping that I have not damaged the chip. Perhaps you might be able to suggest a good source of information about overclocking for those of us inexperienced with it.I built this computer speciffically to overclock.  I didn't spend this much on a computer to not try and overclock with it.

I would say that you are at your max temps at this point unless you aren't concerned about the lifespan of your chip.  I believe thermal throttling starts at around 90c-95c. You should up your frequency in increments of 100MHz or reduce your voltage in increments of 0.015 until you fail a stress test.  Some people stress for 10 minutes and some for hours and hours.  It's really whatever you feel comfortable with or have the patience for. I would be reluctant to go any higher than 1.3v.  Just understand that ASUS did a study on the 4770K and came up with the following generalization within their test sample.  Their tests were run on a closed water system comparable to H100i with a max core voltage of 1.275 under full thread load conditions. 

 

70% of chips can clock to 4.5

30% of chips can clock to 4.6

20% of chips can clock to 4.7

10% of chips can clock to 4.8

 

And if you are overclocking only for P3D  you are not going to see a big gain in frames from 4.0 to 4.5. I know some people on this forum have tested this and posted their results.

Thanks for everyones help. I am happy to report that after reloading my windows OS an P3d I am seeing great results. I seem to have isolated the problem to Ezdock. I am only running Track IR and prepar3d with Ezdock. With trackIR and P3d everything ran fine. When I added Ezdock TrackIR didn't work 50% of the time and I would get fatal errors. So I uninstalled ezdock and the fatal errors went away although TrackIR wasn't working properly. So I reinstalled TrackIR and now everything is running smoothly.
