I have an asus gtx 750 ti 2gb edition with only a fan and I've tried overclocking it with an increase of +300mhz on core clock and +100mhz on memory clock. So far it's stable but am I the only one who thinks it's odd than the increase in core clock is so much higher than mem clock? Is it ok and efficient? Can I get any feedback on this or any advice? Thanks in advance.
