I've got a booster strapped into my K8N Neo2 atm. Been running at 3.1V since I set it up a few days ago. However, I took the case side off today and had a look at the booster, and it now reads 2.8 (BIOS Vdimm set to 2.6). Adjusting the pots makes no difference to the voltage readout. I've taken it out of the computer, and reseated it. Same result.

Any ideas? Is it a dud or does it need some recalibration or something?
