MemTest86 v6 Question

[voyager]

My galfriend has been getting BSOD's occasionally on her PC.
The last 2 were yesterday then again today.
In looking for ways to diagnose the cause[s], running MemTest86 was one of the recommendations of what to try first.

I have d/l'd v6 Free and tried running it on my PC to check it out.
v6 defaults to v4.3.7.
Then, I ran it on her PC.
It also defaults to v4.3.7.

We both have:
ASUS P8Z77-V
Win7 x64 with updates to 3/15/2015.

Her's is equipped:
i5-3570k @3.4GHz [3.518GHz]
UEFI BIOS v1606
8GB DDR-3 @ 1372MHz

Mine is equipped:
i7-3770k @ 3.5GHz [3.605GHz]
UEFI BIOS v1708
16GB DDR-3 @ 1333MHz

Is there a reason MemTest86 will not run v6 on either of these PCs?

Your BIOS configurations may be set to boot in legacy mode. Go to the BIOS setup and check whether UEFI boot is enabled, and consequently Legacy Boot/BIOS Boot/CSM is disabled.

Thanks Keith for your response.

As my dear old mother told me on many occasions:
"Shut your mouth and open your eyes!"

While you were answering my question I saw the post below about disabling CSM in the BIOS.
So, I went back into it and played with disabling CSM.
After saving the changes and rebooting I'm notified during POST that disabling CSM is not compatible with the VGA card. [An XFX Radeon HD 6770 with only 2 DVI ports + 1 HDMI and 1 Display port]
CSM is automatically reset to Enabled.
No matter how many times I Disable it it still gets Enabled.

Here are my choices:
1.
CSM -
Auto
Enabled
Disabled

If CSM is disabled I am given the following choices:
1.
Boot Device Control -
UEFI and Legacy OpROM [Set]
Legacy OpROM Only
UEFI Only

2.
Boot from Network Devices -
Legacy OpROM 1st [Set]
UEFI Driver 1st
Ignore

3.
Boot from Storage Devices -
Both Legacy OpROM 1st [Set]
Both UEFI 1st
Legacy OpROM 1st
UEFI Driver 1st
Ignore

4.
Boot from PCIe/PCI Expansion Devices -
Legacy OpROM 1st [Set]
UEFI Driver 1st

Advice on how to set the option would be appreciated.
I have played with the various setting but have not gotten any satisfaction.

Went back in and played with it some more.
After making the changes noted in the quote above, I can boot into MemTest86 v6.
Thank you.

Now to try it on her PC.
