BSOD ntoskrnl.exe 0x50 Need assistance/opinions


I have just built my new upgrade pc.

Asus Sabertooth
16Gb Patriot Viper
MSi geforce 660TI
80Gb SSD

I had been receiving BSOD's a number of times a day, did my own research and found that it was probably a software or driver conflict going on. Well, so atleast I thought so... because now after a fresh re-install of windows 7 and installing all of the latest drivers it is still doing it.

System Information (local)

computer name: EMZY-PC
windows version: Windows 7 , 6.1, build: 7600
windows dir: C:\Windows
CPU: GenuineIntel Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz Intel586, level: 6
8 logical processors, active mask: 255
RAM: 17121218560 total
VM: 2147352576, free: 1980506112

crash dump file: C:\Windows\Minidump\020513-6224-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x71F00)
Bugcheck code: 0x50 (0xFFFFE8800FFBCA2B, 0x1, 0xFFFFF80002AAC4C5, 0x7)
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This indicates that invalid system memory has been referenced.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

Can somebody help me trouble shoot what might be causing this so I can go return it/refund? It would be greatly appreciated!

  1. Best answer
    I have that mb make sure you have the 1805 bios installed. use the usb flashback port and update the mb for the newest cpu and ram code. also make sure you leave the asus mb speed set to stock on the easy bios screen if you switch it to performance it changes the ram to cpu timing from 1 to 1 to 1 to 5 and causes issues. also in the bios under ai tuner make sure you have dram timing set to xmp profile.
  2. Yes, I have the current up-to-date Bios on the sabertooth z77. I have been running the performance mode in the bios. So that may be the issue. I will try because all my hardware tests passed, and like I stated above, its a fresh install of windows.

    Thanks, I'll let you know if this helped!
  3. Solved: Setting the BIOS to normal from performance has cleared this BSOD!
