Hey guys, I am just curious on why I have such a low memory bus clock than others?

for example, here is my benchmark score:
http://www.3dmark.com/3dm/2784182?

and here is a competitor score:
http://www.3dmark.com/fs/959202

I have a higher clock on cpu than this competitor as well as faster Ram speeds and core clock on both of my gtx 770s, but I received a lower benchmark score. What I see difference is his memory bus clock is 3 times higher than mines, but the question is why is my memory bus clock so low? I'll appreciate your input on this! Thanks. (:

You don't have a low memory bus clock, he just has a really high one. The reference GTX 770's memory clock is more than 100 MHz slower than yours (a bit less when at boost). The "competitor" must have over clocked his memory speeds to get it that high. I wouldn't worry about it, it won't make a lick of difference in game.

Thank you for your reply! If I wanted to achieve roughly similar benchmark scores, can I achieve the competitor's memory bus clock on air cooling?

You might be able to, I've never done it before because of the small performance gains, however it might help with increasing memory bandwidth for SLI. Just download and install MSI Afterburner or EVGA PrecisionX and bump the memory frequencies up a little bit at a time, testing each time for stability with Furmark or something. Keep an eye on the temperatures.

I'm sure you can find plenty of guide on the internet about it :)
