Strange GPU interaction (bump)

[kladner]

Sorry for repeating this question from another thread. I am hoping that someone reading this will recognize the situation.

I have a Gigabyte GTX 460, which has always overclocked very reliably to the upper 800MHz range for mfaktc. When I recently replaced a GTX 580 with a GTX 1060, also Gigabyte, I found that I can no longer change the core voltage on the 460 when the new card is installed.

The only combination I have not tried, yet, is putting the 460 in the first PCIe, and the 1060 in the second. By itself, the 460 is completely adjustable.

This situation occurs both in MSI Afterburner and in Gigabyte's VGA Extreme Engine software. (I really don't care for the latter, but it was worth a try.)

Any ideas or suggestions would be very welcome.

Haven't the 4xx cards had their driver support dropped? Was this before the 1060 came out?

I'm not sure about the timing. I have now found that the 460 voltage is controllable if the card is in the first PCIe slot. At the same time, another strange item is that -d 0 in the mfaktc batch file starts the 1060 in the second slot, and -d 1 starts the 460.
