After further research I realized that memtest86+ is probably testing real memory at "4096M": the highest installed geeg has presumably been mapped at 4MiB - 5MiB. So the errors being found are probably real in some sense.
So I shouldn't have linked this report to Debian report #503860.
But this doesn't change the fact that I'd like to exclude this range and "c | Address Range | Set Upper Limit" doesn't work. Or I don't know how it is supposed to work.
