But anything under 1.6v dram its all 6 gigs and runs everything all day long. What is up with that? I left everything else at stock speeds. Only things changed are, qpi voltage, dram voltage, I set the uclk to 3200 and qpi to 6400.
Seen this before, don't quite know why that happens. I'd suspect something funky with the IMC.

Either way, you are not the only one with this issue. Luckily, there is really no need to set the DRAM voltage past 1.65V ever so you should be good.
