Even if I did get a reading off of the slot, what would be an exceptable votage drop? But even if there was a voltage drop, I guess it would explain the one card choking. Which still leaves the question as to why the cards are failing after an average of...4.5 months ? If this were the case, than the tolerance's on the GPU to reduce the voltage are not able to handle the possible fluctuations of the power supply, which maybe over the threshold allowed anyway...yes ? Hmmm... If time allows it, I will try to monitor the voltages as you described and I am going to purchase a new psu for safe measure. Your explanations seem very technical, which would indicate to me you are in a field of electronics. I certain appreciate the challenge of deciphering through your replies... Regards, ñíñjà¤têç There are multiple VDDQ_1.5 pins, so there really shouldn't be a measureable drop caused by the connector. What you see on the card side should be the same as the copper on the motherboard that carries the 1.5V power. Chips are intolerant to too high a voltage. Too low a voltage should just result in the board crashing or applications erroring out (like a 3D game quitting unexpectedly). With too high a voltage, the circuit will still function properly, but it will be under a life shortening stress. I still think you aren't going to know for sure what is going on, without measuring at the socket, as at least there, you've got a pinout in the AGP30 spec to work with. A supply problem is certainly the easiest to visualize as the source of the trouble, but even one messed up signal on the interface could do it. That is why, at some point, an RMA might be the only way to solve the dilemma, and give you some peace of mind. HTH, Paul |

Thanks Paul, been away for a while, but I am back with my replacement card and a new mobo. It looks like I'll have to keep the "possibly bad" mobo, so I will be able to setup some kind of test bench. Not sure aht to do with the results, but it sure is fun...heh Regards, |
