Need help OC my Gigabyte GTX 780ti windforce oc edition

post #1 of 3
Thread Starter 
Hi! please guide me to oc. i'm new here and need help. My PC spec is
CPU : i5 2500k @4.8GHz
MB : Gigabyte P67A-UD3P-B3
VGA : Gigabyte GTX 780ti windforce OC edition (Driver 344.11, stock bios)
Ram : G.skill ribjawx 1600 6Gb
PSU : Seasonic X-series 750W
OS : Windows 7 64bit ultimate

I use MSI Afterburner 4.0 and Unigine Heaven&Valley. I live in Thailand and no air conditioner so my room temp is about 30-35c. The problem is
1.) I can only push core +60MHz(1223MHz). Idle temp is 36c and max temp is 76-80c. Is it normal or my card is bad?
2.) When i push core +70MHz, i see some black flash in the background of Heaven&Valley. Is this an artifact that mean the setting is unstable?
3.) So i decide to push more core voltage. No matter how much i push, the max voltage my GPUZ read is 1.175v. I unlocked voltage control in Afterburner. I edited MSIAfterburner.cfg UnofficialOverclockingEULA = 1 but still not working. Why? Do i have to flash skyn3t 780 ti bios? or because the temperature is too high so my card automatically not allow more voltage?
4.) Any more advice?

Well for starters with your ambient temps and being air cooled especially I would not try to add more voltage.

What fan speed are you running to achieve those temps? Stock or custom profile? When pushing the overclock components like being as cool as possible.

I am going to be bluntly honest here... 700 series Overclocking is crap. Nvidia restricted what you can and cannot do, and it is quite frustrating.
