Hi. Today i get crash app, when i run Unigine Heaven ( just before loading screen ). I just click RUN and app crash just before loading screen.
I just looked on event viewer and code error is : 0xc000005

Problem Event Name: BEX

Fault Module Name: StackHash_0a9e

Exception Code: 0xc000005 < - this code mean its faulty ram or not necessary?


Does crash with exception code 0xc000005 means its faulty ram?





Also i run memtest86 for several hours without errors.

My ram is 8gb ram Kingston 1600mhz and 4790 k on stock.

If Memtest passes then it's something else.

0xC000005 doesn't necessarily point to faulty RAM, though faulty RAM could cause the error. But since you ran memtest for a few hours, I think it's safe to assume the RAM is good. So it could be an error with the software causing this. From what i could dig up, it's basically trying to reference the wrong area of memory. I did see one report where DirectX was the issue, and updating DirectX fixed it for the person concerned.

I think we first need more info. Which OS? 7,8,8.1,10,32bit,64 bit. Which GPU and driver version? I think if we have that info, we'd be able to help better. smile.gif

Problem Event Name: BEX

Is this related to ram or other component or just software?

Well I think memtest proved your RAM is OK, So i'd be inclined to say it's a software/driver problem. Since you're on Win 7, try updating DirectX with all the updates. It could be driver related too. You could try an earlier driver,like 344.75 or 345.20, and see if it works with that, cos sometimes new drivers can make things throw problems which they didn't have before.

Also, It wouldn't do any harm to try reinstalling heaven. I do really think it's software, rather than hardware, but it's one of these errors where it could be either. frown.gif It could even be a problem with the GPU. You don't have another GPU you could try, do you?

But like i say its very rarely and it crash just after starting heaven when i click run( before loading screen ) . Then app crash. Its very rarely one time of 50 times. And i cant test other graphic card.

well, it's kinda hard to tell. I'd definitely say your RAM is ok, especially if it passed memtest for several hours. I dunno if you have anything overclocked, but if you do, it may be worth backing off the overclock a little, and see if that fixes it. It could be an issue with your GPU, but it could equally be just software. i'd try some other benchmarks, and see if they show up a problem, or if they run ok. If they do, it could just be some quirk with your setup, and heaven.

Exception code 0xC0000005 is an access violation problem in code (trying to access memory which hasn't yet been allocated by the OS. It can also be caused by trying to dereference a null pointer, Windows OS doesn't allow any program to allocate the first 64MB of memory). It's a software bug, not by an actual hardware problem meaning that you do not have bad RAM. Unfortunately, there is nothing you can really do about this but try patching up the software, however, I have noticed that sometimes the latest patch doesn't always fix it. I have games that are years old and still have this problem so the developers don't actually always fix it which does kind of suck.

If I could fix an access violation exception, I would. I have 2 games that wouldn't run on my computer. 1 game was trying to use stuff that AMD discontinued on their CPUs, another game wouldn't run when more that 2GB of RAM was physically installed in the computer. I ended up fixing both games within a few hours by editing byte code in EXE and DLL files as the problem was code that wasn't really necessary. Access violation problems are difficult to fix because the actual cause of the problem could be located millions of instructions before the problem occurs. When you have nothing but EXEs and DLLs, you have to guess what each part of the code does.
