Would the first GPU be flagged for providing Video Output for the BIOS, OS boot process, etc.?

[thunderbolt_fire]

no, no,no
i use intel cpu’s video vga output.
there is nothing it can do but mining …

and the bios is same with the other card .
only difference is its haserate …

is that some else slow down the haserate?

[thunderbolt_fire]

its a old card
by the way

Then, it is not likely a contributor to the low hash rate.

You might want post a snapshot of the settings the miner is actually reporting from the miner window. That is a fairly wide reduction in performance and could be voltage, core, memory, etc, regardless of what you set in the configuration screens.
