Need help with BSOD irql_not_less_or_equal

[jcyanga]

Is this a RAM problem? I have regular BSOD problem irql_not_less_or_equal occur randomly

I did memtest86 3 times, 1 with both sticks, then 1 for each stick, all failed
here are the results

Well something is wrong. But the errors aren't typical for a simple RAM error.

There are lots of bits in error, a wide range of addresses failing and huge numbers of failures in just one test. Plus to see similar errors on both sticks would seem unlikely.

So I would be starting to suspect some other fault. e.g UEFI BIOS bug or bad CPU.

How can I fix the UEFI BIOS bug?

Check if Dell have new BIOS firmware for the machine.
If not, then I would be tempted to report the machine back to Dell as being faulty.

Thank you for your reply. Could an improper BIOS configuration be a cause? There's a June BIOS update on Dell site, mine is currently the Feb version. Hopefully, it's not the CPU, it's beyond warranty period, I can leave the machine idle for a long time and it seems fine.

RAM errors can certainly be caused by setting the wrong voltage or clock speeds in BIOS. But I assume you are running with the default settings.

Thank you. I remember having an "test interrupted. Too many errors" on both individual ram tests. If the BIOS update wouldnt fix, is there software to diagnose the cpu?
