I understand that I am violating SOP by not directly answering the given question, but I am truly facinated by this and am wondering how the BIOS affects what I am guessing are the clock speeds of the PCIe and PCI interfaces.
I know I should technically start a new thread, but my question would reference back to this and become hopelessly convoluted.
Basically, can someone explain what is going on here? Is the PCI or PCIe slot being overclocked by the BIOS somehow, though "fast motion" is NOT what I see from MY overclocked GPU (I just see improved performance)? Why would reducing the memory make a difference? Can this sometimes explain unusually slow GPU performance as well? Can something be learned here (by a dummy like me) to improve GPU performance?
I recall 30 years ago (insert "old man" voice) my first clone had a "turbo" button that would cause some games to run too fast, but that was in the wild and wholly days of DOS when both the BIOS and OS were much less regulated.
Again, I know this post is not an answer but I would appreciate an explanation of what exactly is going on.
