If someone has a solution to this i would be forever in debt.

So, the last few days when I play starcraft it just randomly crashes. Doesnt give me any errors just crashes to desktop.

My PC was upgraded 6 months ago and I have like a really good CPU/GPU etc.
Temps are fine. I even run a memtest and it was ok. cause the only thing i changed 1 week ago was upgrade my RAM from 16 GB to 32GB.

I even formatted my PC today and reinstalled everything and first game i played on ladder it crashed again.

Another thing I noticed was when browsing some websites I get some errors on chrome. Like

Status_Access_Violation
Status_Breakpoint

Mentioning that because it might have a relation to the starcraft crashing thing.

Also I have never had any problems with other games except starcraft.

I have updated my drivers etc. dont know what it could be.

I also just installed windows 11 just to test them out and will test SC in that OS enviroment as well now.

I think win 11 fixed it.

Probably ram. Did you exchange ram sticks or added? If you added you need to downclock ram for stability.

If exhanged sticks you enable xmp profile in uefi and run something memory heavy.

Reasons can be your chassi inside temp raises as pc runs and that will affect ram stability.

A fix can be a fan straight onto ram to remove heat fast.

Memtest has to be run for 5 hours at least and also while having gpu/cpu running something heavy to heat up chassi temp.

I would recommend to use the softwares ahoc uses as he knows what hes doing and whats the most memory heavy that properly tests the ram:

I myself has used memtest86 previously but thats legacy now.

Set a frame limit in SC to keep gpu usage low to keep temps low.

Edit: When you buy a kit of ramsticks those are xmp preconfigured ram timings to work together, if you add a second pair these ramstick may use other timings and longer traces on 2nd ram slots causes more instability.

A ramkit of 4x have other timings (xmp) to work just in these longer traced slots (slot 2 and 4 on mobo).

Thats why using 2x2 ramkits dont work with preconfigged xmp, you will have to downclock (loosen timings or raise voltage) to fix the instability.

You could sell the sticks and buy 2x16GB sticks to keep best stability.

You might be right........ What I did is buy 2 more 2x8GB sticks , same manufacturer, same clock speeds, exactly same model.
So do I have to go into my mobo settings and enable the XMP profile?

You can try that first, but buying the exact same sticks but per pair can lead to different values needed.

Most motherboards (i dont know about the newest ones) use daisy chain topology that means the traces to ram slots are of different lengths, this results in all slots used being less stable than just using the 2 shortest traces (which is why i said 2x16GB is preferred)

While on a T topology board you would get best performance by using all slots instead of just 2.

Do you mind posting system specs?

CPU: intel i7 12700K
MOBO: Gigabyte B660 Gaming X
GPU: GeForce 4070 Ti
RAM: 32GB Corsair Vengeance 3200MHz

Also after streaming/playing Grim Dawn today for many hours and other games for many hours like cod mw3 i never have any crushes. so being a RAM thing i think is not possible...otherwise other stuff would crush as well....due to faulty RAM clocks or w/e.

Im gonna wait for blizzard to reply to my ticket. they asked for my msinfo file and dxdiag file so they should see everything PC related.

*UPDATE*
Blizzard replied on my ticket and said to run a sfc scan on my windows. i did that and windows found i had some corrupted files in my registry so it fixed them automatically. maybe that was causing the problem? I will play SC again and test if it crushes or not later today.

Crashes still happening. Also about the ram s. I did a cpuid test and all clocks are running fine and xmp profile is ok. So its not a ram issue. Other things i noticed crashing are web browsers. Other than web browsers crashing randomly in some sites and starcraft all other games etc run with no problem.

Remove the old ramsticks and run only the new ones in slots marked in manual, enable xmp profile, then try for a week.

That's SC2 being a decent stability tester there :D

Highly likely instability on the RAM / memory controller.

XMP is an automatic overclock (best avoided when troubleshooting likely memory instability) and you don't have one that is valid for your memory configuration so you should be at spec memory settings for sure unless using only the old or the new 2 sticks in slots A2 B2. Maybe even drop to like 2133mt/s to see if it helps.

Run a stress test like ycruncher VST. None of the other stuff that you're doing is particularly taxing on RAM, nor is it looking for errors; it's only breaking when something goes catastrophically wrong, which might take a while. ycruncher will error on demand and then find those errors for you if there is a hardware or configuration problem. In general it is good practice to run a test like this overnight with a new setup or with any configuration changes e.g. XMP / overclocking to validate stability.

2 more 2x8GB sticks , same manufacturer, same clock speeds, exactly same model

This isn't good enough:

Many (most) vendors resell memory chips from different manufacturers with the same label on them, and don't give consumers any way to differentiate. Likewise there can be differences with the PCB used, or even different rank counts if different chip densities are used. If it's not literally in the same box you have to assume that it's different in ways that you might not understand which can break things.

Configurations with multiple DIMMs per channel are also much slower and more complex; by adding sticks you change the memory configuration, which is a problem in of itself.

In general for the PC building "meta", multiple DIMMs per memory channel is best avoided unless absolutely required for the needed capacities. With only 1 DIMM per memory channel you can get 64GB (2x32GB) on a dual channel CPU on DDR4 so the drawbacks and headaches of using more rarely have to be an issue. If multiple DIMMs per channel are used, stable frequency will be lower than otherwise and it will be more reliant on additional settings and tuning on the motherboard side.
