I wouldn't rule out memory completely from a single pass of memtest (a little under 3 hours, would suggest 1 pass). It's not that uncommon for errors to not show up on the first pass, I've had sticks where the errors have only made their appearance after 2-3 passes (I assuming it needed extended stress on the memory controller or the memory to warm up before the issues popped up).
I'd be tempted to try memtest86 over + as well (+ is an opensource fork from the original memtest86), as + has not been updated for a while, where as 86 has and officially supports haswell-e & ddr4. I've seen the odd post around as well from people with ddr4 systems saying + missed the error.
Either way, I wouldn't rule out memory with a single run. Fair warning if you try 86 though, default test is 4 passes, so will take quite a while with 32GB memory.
