I've asked if they'd exchange my die #0 issue boards with Nov type ones as RMA, I received a clear "No", only Oct type boards (hopefully good ones). Been told I'll receive a shipping label from UPS, didn't receive it... yet.
"We will only be able to re-place your boards with October batch boards."
Well, on the plus side of that, my 3 RMA'd boards function perfectly and have no heat issues or anything. Too bad I still have 4 more with issues. They also don't hash any faster so I guess us October folks are stuck with what we got.
