GTX 675MX Good Overclocker

[MaydayMAc]

I very pleased with the GTX 675mx it overclocked to 919Mhz on Core and 1325 Mhz on memory stock is 719/1250

and it actually makes big difference in

ive tested lost planet 2 in dx 11 getting 65 FPS in benchmark at 2560x1440 everything max

Borderlands 2 getting 56fps

temps got to 85c max suprised how quiet the cooling is

Wow, pretty nice OC! And I'm really surprised with the stock clocks being way higher than what nvidia claims for 675mx.

At my oc clocks everygame Ive tried works /plays fine

By any chance, do you mind running some benchmarks (Heaven).

Is there a possibility of damaging the screen over time by overclocking the graphics card (heat damage)? (Not to scare people from overclocking their iMacs, just wondering.. )

No.. I have the Fans running 100%

Impressive! I don't feel so bad about not getting the 680MX. Comparing Heaven scores, it would seem you would only need to do a little bit of a OC speed bump to match the 680MX performance and likely still run with the fan at stock speed or only a fraction higher.

all the games I play run great at this speed.
