Kepler, core clock or memory clock most important?

[Mr Paul]

What's the most important factor in Kepler overclocking, it's own speed or the memory interface?

Thanks

Paul

Core speed will give you the biggest boost in most games - 1-2 things like Heaven benchmark sees fair gains from memory overclocking but the primary one is core.

 

[Mr Paul]

Cool, thanks bud

Keep in mind when overclocking kepler that the core and memory clocks go up in steps (or bins) IIRC the core goes up in 13MHz steps and the memory in 6MHz steps. (So increasing/decreasing by say 5-10MHz at a time is pointless if its not enough to go upto the next speed bin or fall back to the one below). Check the sensor tab in GPU-Z to see what is actually being run for any set clockspeed.

Yes knew about the 13Mhz core, currently at 1280 Boost on a 770.

Didn't know about the memory, ta

 

[Mr Paul]

Had to add +12mv to get Heaven to pass at 1293 Boost.

Hopefully I can make 1.3Ghz on the core.

 

[Mr Paul]

Nope 1293 is the max

 

[Mr Paul]

Managed to get 1293 Core /7372 memory

Can you add any more voltage or bump the power limit. Might help reach 1300 (assuming you are still interested in it)

Core. Focus on core

Max voltage and max limits.

1293 is stable in Heaven 95% of the time, so reduced it to 1280 stock voltage and power limit (I.e. maxing the voltage and limits only gives me a small not quite stable increase)

Core, although memory has helped me for some games (EG: having faster memory had noticable faster texture loading on BF4)
