You guys with low vdimm restrictions could try vdimm mod to raise baseline a little. You can do by pencil if you desire. so for example if your sticks are 2.1v anyway, just set baseline until it goes from 1.8v to 2.1v. Then you'd have the ability to stretch to 2.3 or 2.4 depeding on how much you can change vdimm in bios.

Note though it may or may not work, since the higher vdimm might not be a bios issue but rather a board defect. I've seen it in a lot of ds3's, and two of mine were affected by it too.
