Windows 7: Intermittent BSOD Memory Management

16 May 2016   #1

Intermittent BSOD Memory Management

Hi all,

Having the most difficult time finding whats wrong with my PC. Its a new custom built. All new components.
The ram is new so I'm thinking the BSOD is software related. Maybe firmware or driver. Windows 7 update is all current. I tried running my system XMP mode thinking maybe my RAM needs more voltage but it still continues to BSOD intermittently. Any help would be greatly appreciated.


OS: Windows 7 Ultimate
CPU: 4790K
MB: Asus Sabertooth Z97 Mark 2
RAM: 32GB Corsair Vengeance Pro 2400 Mhz
HD: SanDisk Ultra II 480GB
Video Card: using on board HDMI display port

Hi rodney174,

Welcome to the 7forums :)

Please revert back all overclocking to ensure it doesn't cause problems.

Please run MemTest86+ per below instructions, if MemTest86+ comes up clean run driver verifier per below instructions.
Read the instructions carefully, if you have any questions please ask :)
Please note that it is better to read carefully and ask questions before you run the test than while/afterwards to ensure the tests are properly performed.

Intermittent BSOD Memory Management Diagnostic Test Intermittent BSOD Memory Management

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

Note   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it.

If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

warning   Warning
Please make a backup of your important files and get your rescue media or create one.
Please create a restore point.

Please follow this tutorial to run driver verifier.

Some windows drivers are blamed in a few crashes, but that usually means that a 3rd party driver is actually the cause.
Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.

Note   Note
Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.

Thank you for the warm welcome and looking into my problem. I have run memory test and it passes. I did the driver verifier and it crashes right away. I get the following BSOD error IOMap64.sys - Address FFFFF88008FE9708. I will try to find or update this driver.

What test did you run? 32GB cannot be tested completely in such a short period.

Iomap = IObit driver, remove the software.
