Is there anything that could possibly be causing this, other than faulty memory...

Video of my memory failing memtest.

Is there any BIOS setting that could be causing this? I've tried all combinations of settings, below stock clockspeed and above stock voltage, but I still get nothing.

Or prehaps any hardware problem?

Although apparently it has been tested for 20 hours memtest stable after an RMA being returned to me...so I'm kind of stuck with what to do with it now

Faulty cache? Is there an option to turn it off in the BIOS?

I'll try that in the morning... must note that my other set of memory I bought while it was away on RMA functions perfectly, as does one of the two sticks of the faulty set.
