No. With the 5v setting it will draw the vdimm from the 5v line. This puts more heat on the vdimm mosfets and around that area, so it needs to be cooled good.

With the 3.3v setting enabled, it would draw the vdimm from the 3.3v line. Max vdimm would be 3.3v but this is 'better' for users 24/7 not running high fsb's and not having to add extra cooling to the vdimm mosfet area.

With OPB using only 2.9v for his GsKill TCCD why use the 5v feature when you can use the 3.3v feature and not put as much 'strain' on the vdimm mosfets.
