BSOD at least 2 times a day, various error codes

I collected all the data, that I could, but for some values my BIOS only says it's at "Auto" and I can't seem to find out the actual value. Please tell me that I can still use my RAM :) Maybe if I reduce the frequency?

Sorry for spamming, I just found the tool HWmonitor and used it to find the missing values. Hope it helps.

Try setting the first four timings to 9-9-9-24 and the frequency to 1333 MHz. See if that provides more stability first. Then we can try some other settings if needed.

Thanks for the advice, I'll try that as soons as I'm home again :)
Do you think buying a new PSU would improve the overall stability of my system, or should the current PSU (bequiet 450W) be sufficient for my setup?

The current PSU is probably sufficient, but it is difficult to say for sure. Running with a lower power PSU when a higher one is recommended can put strain on the PSU and lower its lifetime. If it were me, I would consider replacing the PSU at some point to provide better stability and reliability to the system.

Hello again!
Yesterday I set my memory to the timings and frequency you gave and everything seemed fine. However, when I booted up today, I soon got another BSOD (minidump attached) and the computer would restart by itself
What are my options now?

Crashes still indicate memory as the likely cause. Bump your NB Voltage to 1.2 Volts (or as close as you can get) after setting it to manual.


If you still get crashes with those settings:

• An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
  
  a. Backup your system and user files
  b. Create a system restore point
  c. If you do not have a Windows 7 DVD, Create a system repair disc
  d. In Windows 7:

  • Click the Start Menu
  • Type verifier in Search programs and files (do not hit enter)
  • Right click verifier and click Run as administrator
  • Put a tick in Create custom settings (for code developers) and click next
  • Put a tick in Select individual settings from a full list and click next
  • Set up the individual settings as in the image and click next
    Attachment 217176
  • Put a tick in Select driver names from a list
  • Put a tick next to all non-Microsoft drivers.
  • Click Finish.
  • Restart your computer.

  
  
  If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.
  
  If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.
  The idea with Verifier is to cause the system to crash, so do the things you normally do that cause crashes. After you have a few crashes, upload the crash reports for us to take a look and try to find patterns.
  
  When you are ready to disable Verifier: Start Menu -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator -> Type the following command and then Enter:
  verifier /reset
  -> Restart your computer.

Thanks, I will try the verifier-approach. But I guess it's something with the hardware. Just now, my computer refused to boot up, freezing once inside the BIOS and a 2nd time during startup (BIOS splash screen). The third time I succeeded...

That definitely sounds more like hardware. Verifier probably won't yield anything useful in that regard.

You may need to swap out the PSU and/or memory.

Hello again!
Thanks for all your support. I switched RAMs and now the system is somewhat stable. Today however, I encountered a funny problem. I pressed the button to power up my PC and it would take a couple of mkinutes before it would boot up. Lamps and everything were lit, but the boot procedure only started later. Strange, maybe the PSU is not working properly after all. I guess I will order a new one today and see how swapping it works out
Once again, thanks for all your help! I greatly appreciate it!
Have a nice weekend!
