Maybe you have a bad stick of memory? Have you tried testing them with memtest?

Maybe it's not RAM. 0x00000024 sounds suspiciously like it might be a reserved memory location that doesn't map to installed DRAM.

I just did a memory check and no errors at all so I do not think its RAM issue, their are a few people complaining about the same problem. Hopefully bliz comes with a fix soon

Whoa another person with the same problem!

It's possible it's not the ram? I tried doing a memtest but I failed to get it to boot to cd so I just took it to the local store for them to check it out. They did it and apparently didn't find any problems with it. I left it there for about a few hours so I think they did a few cycles with it.

As for if there's an error with anything else, I have BSOD'd once or twice I think but I always did SC2 stuff right before. I haven't played most any other games.

BTW, where are these people with the problem? Can you direct me to a link? I don't think I've seen anything like this on the blizz forums.

@KOF, I ran the test for about 2 hours took a little nap during it, and no errors
@R1CH its just SCII and it just started recently, I've played most of beta and since release never crashed in an actually game. Then I updated windows and got the latest patch and I almost crash constantly.
@DcBerkeley, I highly doubt its a our PC problem here is one thread I posted it
http://us.battle.net/sc2/en/forum/topic/628240449?page=1#10
And here is another one with a few replies
http://us.battle.net/sc2/en/forum/topic/791239965
Here is some guy claiming fix it yourself, I did a few thing he suggested but haven't tried it yet

If you could find the error report in the Windows event log (control panel - > admin tools -> event log - > application) and copy/paste it here, it will provide more information on which module is crashing. This looks like a null pointer dereference, so either a bug in SC2 or some 3rd party module loaded into SC2 is causing it.

I have the exact same problem. I have checked the RAM - no errors. I dont use any 3rd party programs. It is only a problem when I run SC2. I have crashed this way in 7% of my 1v1 matches.

I also get this problem. Ran memtest for 12 hours no probs, checked hard disc for errors, run sc2 as administrator, got a gtx 460 so I've tried the beta drivers to and cleared temp folder.

Also tried changing shader settings. Game runs fine apart from these crashes

Updated all drivers, at a loss really.

Here's what it says on my last crash

ACCESS_VIOLATION (0xC0000005)
occurred at 0023:6CCCB6B2. The memory at '0x692047A8' could not be read.

sent dxdiag/msinfo and crash txt to blizzard tech, no response yet

Cant find any error reports in windows event logs

This has been happening to me alot as well. I tried to run sc2 with my old 1950pro radeon card, which coincidently worked fine in my friends pc, and it froze with this msg every time (in the sc2 error report). I have since switched to my onboard graphics card and for some reason it runs smoothly now. Although today I got dropped from 2 1v1's with the same error, I was able to play 5 1v1;s and 2 4v4's with no problem. Idk what it is, but I have a phenom 2 555 asus ma88t-m mobo with integrated hd 4240 radeon graphics with latest catalyst drivers... 500 gb hd 2 gb dd3 ram

memtest takes at least 8 hours to give you reasonable confidence that your ram isn't bad, it can never tell you your ram is perfect.

that being said, if you are always getting the exact same error (complaining about the exact same memory location) then most likely you have a driver problem. experiment with different vid driver versions, see if there are updated firmware for either your mobo or vid card. fiddle the with SC2 graphics settings, such as toggling vsync and disabling physics.

The memory at '0x00000024' could not be read.

might be a software bug, dereferecing a null struct pointer member

mov whatever, [eax+24] with eax = 0
