I actually made this change just an hour ago and it worked very well! I didn't realize what a difference in performance it would make. Wow.
The card will still throttle due to power limit so I'll move that around in a little bit but I didn't expect this small change to have such a big impact on my card's performance.
I'm excited to dial in the xbar and l2c next.
The card also still won't climb up past CLK 63 even if I shift the max table clock down. If I tell it to fix invalid clocks it jumps right back to 1531 max boost but since I have it locked at 1481 it's a non problem.
I think the card can do maybe 1487 max stable, is there any way to move off of the 13mhz increments?
