SCORE:2718 points (45 FPS, 60000 ms) @ 1.1v
SCORE:2818 points (46 FPS, 60000 ms) @1.088
SCORE:2833 points (47 FPS, 60000 ms) @1.075
failed @1.063 (driver crashed)
failed @1.050 (driver crashed)
failed @1.038 (driver crashed)

this would show that the voltage sweet spot would be 1.075 volts... is this wierd behavior?

this test was done with stock memory and a core set @ 900 mhz.

SCORE:2530 points (42 FPS, 60000 ms) @ 1.1 / 2002 mem
SCORE:2533 points (42 FPS, 60000 ms) @1.1 / 2005 mem
SCORE:2577 points (42 FPS, 60000 ms) @1.1 / 2010 mem
SCORE:2544 points (42 FPS, 60000 ms) @1.1 / 2015 mem
SCORE:2545 points (42 FPS, 60000 ms) @1.1 / 2020 mem
SCORE:2514 points (41 FPS, 60000 ms) @1.1 / 2025 mem

these tests show the gpu like 2010 mem the best. going to try with some different voltages with 2010 mem and see what results are like.

SCORE:2534 points (42 FPS, 60000 ms) @1.100 / 2010 mem
SCORE:2516 points (41 FPS, 60000 ms) @1.088 / 2010 mem
SCORE:2570 points (42 FPS, 60000 ms) @1.075 / 2010 mem
SCORE:2616 points (43 FPS, 60000 ms) @1.063 / 2010 mem
SCORE:2629 points (43 FPS, 60000 ms) @1.050 / 2010 mem
SCORE:2840 points (47 FPS, 60000 ms) @1.038 / 2010 mem
SCORE:3098 points (51 FPS, 60000 ms) @1.013 STOCK voltage / 2010 mem (WIERD?)

Well after running this stage of tests / benches its seems to me that the memory doesn't favor a specific voltage. Infact the core seems to determain what voltage the gpu should run at for best optimization. Thoughts?

Now to try core + mem + voltages and see some results.

SCORE:2668 points (44 FPS, 60000 ms) 1.1
SCORE:2797 points (46 FPS, 60000 ms) 1.075
SCORE:2735 points (45 FPS, 60000 ms) 1.063



SCORE:2844 points (47 FPS, 60000 ms) 910 core / 2010 mem / 1.75v
SCORE:2811 points (46 FPS, 60000 ms) 913 core / 2010 mem / 1.75v
SCORE:2864 points (47 FPS, 60000 ms) 910 core / 2010 mem / 1.75v


tell me what you guys can make of this?

Why does higher voltage cause worse performance?

Well first off, if you don't need the voltage added then don't add it. There's no need to and it only decreases the lifetime of the card. The drop is FPS can caused by 2 things.

1. There isn't enough voltage getting to the card, causing it to not get the full FPS/Score you want.

Now why the card gets worse performance from HIGHER voltage is beyond me... I'm guessing maybe the card can't handle it? That it needs to be clocked higher in order to use the potential it has? I'm only guessing though, hope it helped some.
