Overlock GPU: Core or Memory Clock?

GeldMiningGeldMining Member Posts: 1
Good day,
should one overclock the core or memory clock for mining? This discussion said the memory clock is the more important one, https://forum.ethereum.org/discussion/4302/how-to-find-the-optimal-gpu-clock-speed-for-mining/p1. However, when I overclock the memory clock with 300MHz, the hash rate only changes with about +0.5MH/s and when I overclock the core with 100MHz I get about +1.5MH/s more.
I even cranked up the core clock by 170MHz and now I'm up to 20MH/s. The overclocking settings probably differ from GPU to GPU. Would it be wise to underclock the memory clock and overclock the core clock more, in my situation?

P.S. I have a Inno3D iChiLL GeForce GTX 780 HerculeZ X3 Ultra.

    I'm facing the same issue with my Sapphires RX 470s 4GB (non+) - memory clock has no effect on my hash rate. only gpu clock gives some increase.

    Can you pl. share what cards u are using?

    I would edit your bios using polar bios editor and ati winflash

    If your not sure what you're doing in sure someone would offer their skills for some ether

    Look for "timing straps", there's plenty of topics in this forum about this.

    You can't edit the bios of a GTX 780 with polarisbioseditor :)

    When you overclock your core clock, you give a boost to power consumption, so it's probably not worth it, but you should measure it, besides i think you can give much more to the memory than 300.
    But i never owned a gtx780, so don't know anything about it.
    Maybe you'll found info about your cards limits in this topic: http://www.overclock.net/t/1393791/official-nvidia-gtx-780-owners-club
