GTX 660ti Owners Club

[ginnnnny]

I get that part, that's why I'm going over every possibility that could be causing it to happen. Hence my questions. The fact that you're getting 1293 mhz at ~100% tdp is astounding though, almost makes me wonder if the power percentage isn't reading properly?

Mine has always had a really good boost

Straight out the box it was up to a solid 1205mhz and then with plus +100 core in msi after burner it was up to 1305mhz(on original bios).

Like Crazy said though mine is probably limited by the total board power limit which on my card doesn't want to go above 100% tdp.

I give you an example when comparing mine to my friends 3dmark11 graphics score.
original bios
my own msi 660ti at 1305mhz 100% tdp: 9852
friends asus 660ti at 1240mhz 115% tdp: 9830
I always had much higher clock but mine was being throttled by the board power limit which made us about even so this in it self is evidence that mine is infact being throttled by power limit.


new bios
my own msi 660ti at 1300 100% tdp: 9840
friends asus 660ti at 1260 125% tdp 10200

The new bios we tried I actually lost a little performance in benchmarks because mine was getting throttled sooner. where as my friends asus 660ti which is still at lower clocks than mine but now takes 125% tdp is raping my score.

I agree that mine running at a solid 1300mhz is great and if indeed Crazy can work his magic and get the total board power limit up a bit higher then my card will be a monster.

I compared my bios to the someone else and they were exactly the same
Could it be possible that my motherboard (am3) is holding back power?
I will be getting a msi gd65 z77 for christmas so I was thinking that might help me a bit.
