Could it be that memtest86 itself has a bug or cannot execute the tests correctly?
Possibly, one thing to check for might be any bios updates, also try setting the RAM speeds manually in the BIOS (try underclocking the RAM) if those can't resolve it then I'd start looking at a hardware fault but this could be caused by cpu or pci cards so I'd strip the system down to a bare minimum.
One other option is that if it's the same memory area then you can always try specifying the memory range linux can use to exclude the faulty area. Also, trying to run some user space memory testing tools.
