gtx 980 o/cing

just curious as too what a safe voltage range is for overclocking a gtx 980. the card is watercooled and current temps right know are about 31c. how much voltage should i put into this card when overclocking? im currently using asus' gpu tweak for o/cing. any thoughts would be greatly apreciated. thx

Without BIOS/hard mods you won't pass safe limits and you can move voltage slider to the max. Standard will be +37mV or something near so under full load after setting higher power limit and voltage to the max it will go up to maybe 1.25V, maybe slightly higher. Limits in software are about max safe within Nvidia specs.

awsome!! thx man, i dont have any bios/hard mods so everything will be done within gputweak

Just so you know, these cards will tend to throttle due to TDP being reached long before anything else. Raising the voltage will also raise wattage, thus getting closer to that threshold. Incremental adjustment of the core and memory clocks and frequent testing is the best way to find the max overclock on these cards. Only raise voltage if you absolutely need to, and back off when you start to see benchmark scores drop, indicating throttling.
