Hello guys, I have an pny gtx 770 with problems on 1 bank of ram. After desoldering the ram chip and measuring the pads, Byte 1 and 3 data lines are ol and no voltage drops are observed and ohms are maxed. The likelihood of all the data pads having a bad ball connection to the gpu core or the traces damage is low. I just want to confirm if this is a result of a damaged memory controller on the gpu die.
