I have recently begun testing a new build system more extensively, due to ongoing research into finding best settings for a motherboard BIOS.
I have encountered a situation where I had the system running stable with AIDAx64 extreme stress test, then installed Intel XTU which has the ability to adjust motherboard settings and after doing this AIDA began throwing up flags for hardware errors during testing which caused it to stop the tests, sometimes after an hour sometimes after ten minutes. These settings had passed 8 hours of memtest 86+ but I rolled it back anyway to default plus XMP and a slight underclock of 4x41 for turbo which should be rock steady but AIDAx64 continued to stop testing with hardware errors.
However with the same system settings OCCT runs fine for three hours without any errors at all and Intel XTU CPU stress test likewise is error free and (edit) completed and passed a 3 hours 5 mins run.
Is it possible that a conflict of some kind is causing an hardware error to trip in AIDAx64 when there is none? Intel XTU can access and adjust the mobo settings directly from the OS so I was thinking it may have all kinds of access and services and registry settings which maybe could conflict with AIDAx64. Does that sound possible?
