After 5 hour flight, just putting decent altitude .FSX crashed.

 

I received the following error messages. This is happening second time in last two days.

Will you please advise how to solve this problem.

Thanks

"Time you enjoyed wasting, was not wasted"

Look for corrupted system files via this tutorial - http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html. Fix if any are found.

 

Exception Code: c0000005 indicates a Memory Access Violation. This could mean a ton of problems occurred. Since you were flying for five hours, it could be an overheating problem. Memory/dram/CPU voltages may not be correct and too high or too low. Here's a guide I use for various BIOS settings that should not be exceeded - http://www.techreaction.net/2011/01/04/3-step-overclocking-guide-%e2%80%93-sandy-bridge-v0-1beta/. It could also mean a hardware conflict or malfunction or bad video/sound card drivers. Your FSX settings may be set too high and you are putting too many resources on your system and system hardware.

 

If none of the above recommendations work, I would suggest a Google or Bing search for 'stackhash_0a9e bex'.

 

Hope this helps!

 

Best regards,

Jim,

Thanks for your reply. I run the SFC/SCANNOW. No violation found. Last week DELL OC my Intel® Core i7 CPU X 980 @ 3.33GHz to 4GHZ. They run Torture Test with Prime95.exe software over an one hour. Passed.

 

That is the second Exception Code: c0000005 in this week. My GPU heat around 65-71 Deg. CPU first core some times reaches over 70 deg. I wonder 4GHz OC is causing some problems. Will I go original manufacturer OC 3.6GHz? or continue with 4Ghz OC?

First time I heard of Dell overclocking! LOL! :Just Kidding: I once had a Dell XPS 720 that I was able to overclock from 2.93 to 3.73GHz but I was responsible for any damage done to the system. It was a simple process and explained in their manual. I did it in the BIOS under the Performance setting and the BIOS would set the other settings in the BIOS commensurate to what GHz I selected. It would even allow me to go higher and I did try it but started seeing some crashes so lowered it back to 3.73 and that was very stable with FSX. I don't know if this is how Dell overclocks their systems anymore. I seriously doubt 4 GHz is a problem with the 980 CPU but you might want to check into your BIOS and see if there's a performance setting that allows you to lower your setting back a notch or two or bring it back to the factory setting. My current system, shown below, was built by me and I did the overclocking (with the help of Stephen (SpiritFlyer) here at AVSIM). I had some BSOD's and just simple FSX CTD's soon after with the Exception Code c0000005 displayed. I ran the "Torture Test" with Prime95 too and never saw an overheating problem and the system passed. I ran the Intel Burn Test V2 too. Again, no crashes and no overheating. But, occasionally I still got a BSOD or a FSX CTD with the Memory Access Violation code always displaying. I ran the BlueScreenView program and found that I had had several crashes related to system memory. I went into the BIOS and changed the memory frequency from 1600 MHz (what my memory is rated) to 1333 MHz. The crashes stopped. I know now I should never have set my memory frequency to 1600 MHz as that setting is only available if you use the X.M.P Profile for overclocking a system (I had manually set my BIOS settings). So I set the frequency to 1600 MHz and the timings and voltages for my memory in accordance with CPU-Z under the SPD tab (and for XMP). I now have a very, very stable system and can't recall when I got the last crash (oh, it was with the g3d.dll CTD that many were getting with ORBX FTX PNW installed and fixed with the latest FSUIPC). So these might be some areas you should investigate. Again, too high FSX settings will also cause crashes related to the Exception Code c0000005. Good luck!

 

One last thing.... BEX refers to Buffer Overflow Exception. Buffer overflow is a condition when some process tries to store data beyond the capacity of the fixed/available buffer so it tries to overwrite some other memory locations, too. Some people say that changing the DEP setting to exempt FSX is what should be done but I don't believe FSX will allow this setting to be changed. You might want to check your virtual memory settings and make sure they are set at the recommended setting of System Managed Size. If you're unfamiliar on how to accomplish this, goto the Start button and, in the search bar at the bottom type Virtual Memory then look up in the menu and click on How to change virtual memory settings.

 

Best regards,

Jim

Jim,

 

Thanks for your detail/rich explanations. May be its better I go back to original manufacturer OC 3600Mhz. I agree with your statement "I seriously doubt 4 GHz is a problem with the 980 CPU "

My .PC was stable at 3600 Mhz. I don't hear any load fan speed ilke 4000Mhz settings

I dont know how to check .BIOS performance settings and made a necessary adjustment.

DELL set my virtual memory settings:

Custom size

Initial sizeMb 6000

Mx size Mb 12000

 

Best regards,

Ahmet Sanal

 

"Time you enjoyed wasting, was not wasted"

DELL set my virtual memory settings:

 

I can almost guarantee that is the problem. Change to System Managed Size and see if that fixes the problem. If not, you can always return to your custom settings. I'm thinking your system was 'factory overclocked' to 4.0GHz by Dell. In that case the overclock should be okay. But it also means you can overclock higher too (as I was able to with my Dell XPS 720). Here's how you get to the BIOS on your system - http://support.dell.com/support/topics/global.aspx/support/kcs/document?c=us&l=en&s=gen&docid=DSN_148562&isLegacy=true (tapping on F2 at startup). Your manual will have a detailed explanation of what every setting in the BIOS accomplishes and whether you can change it or not. Fan speeds can usually be changed in the BIOS too. Again, because you got the BEX or Buffer Overflow error, I am almost positive your virtual memory settings are causing the problem (especially after 5 hours of flight).

 

Best regards,

Jim

I am glad I asked this question to you. I changed to "System Managed Size". I will fly the same route again, KALB-TNCM. Will inform

CPU OC will remain in 4.0GHz.

Thanks :Peace:

Jim, thanks again. I just completed flight without ANY INCEDENT, I think" System Managed Size" did the trick.

Best regards :Party: :Party:
