    Hi,
    I've got an MSI Geforce GeForce GTX 680 OC Twin Frozr and according to the hardware specs, my memory clock should be at 6008 Mhz. However via monitoring softwares I see that it is staying at 3005 Mhz. Is there something I'm missing ? Could someone explain to me why my memory is underclocked ?

    It's not under clocked. Your clock speed is divided in half

    6008/2= 3004Mhz

    Most monitoring will monitor the memory speed at half the true speed of the memory, so it's running fine. I think it does it this way because I THINK vram is read at a factor of 1:2.... actually it should be higher because it's GDDR5. The true number that you number you pick for the VRAM should be like 1200 because of the nature of GDDR5 I think.

    ANYWAY, we got used to viewing and overclocking VRAM this way (cut in half).
    When you overclock, think of it this way- it allows you to adjust the speed of the VRAM by .5 rather than 1.

    Alright, thanx for your answers. That explains it all. Btw is there a way to show the result as the sum rather than the half ? And is it worth it to OC the memory on this particular card ?

    You could obviously do the math yourself OR open NVCP (rightclick desktop, NVidia Control Panel), then press 'System Information' in the bottom left corner. Read Memory Data Rate, should read it as the number you are looking for. Just close and reopen it if you overclock, it should change.

    The clue is in the name; DDR or double data rate.

    I've found very little returns when oc'ing the ram on mine as it couldn't be pushed too far at all; ymmv, I just leave it be and boost the core clock, 680's (surprisingly) aren't memory bandwidth limited.
