I just flashed both my Titan HC's with the OC bios last night and while both seem to be working fine, I'm encountering some problems in nvidia inspector. For my first titan, all of the options for increasing voltage, base clock..etc look the same as they do in the demo video and other pictures posted by users on this thread. When I select my second Titan to apply the same settings, my voltage slider has changed to an "over volt slider" ranging from 0 to 32.5 mV (for a max of 1.20 V). Also, I can only move my base clock slider for the second card 10-20 MHz, before the "estimated max" shoots above 1200 MHz. This is in contrast to my first card where I add +200 MHz on the slider and can reach a voltage of 1.212 V. Has anyone encountered a similar problem when dealing with Titan's in SLI? Also NV Inspector shows the same bios ID for both cards, but the first card has "Modified" beside the ID. I've gone back and re-flashed the second card, but there were no changes. Any ideas?
