About standard PCB

Hi 

 

I decided to buy an EVGA GTX980Ti SC+ to replace my 960 FTW.

 

It seems the SC+ is using reference Nvidia PCB and just had the 2 metal plates + ACX cooler.

But i didn't had a reference pcb since long time ago... and i love to do a bit of OC.

 

Do reference pcb limit the oc potential that much ?

Reference PCB' s don't have overclocking potential in mind. Non-reference PCB' s are made so the manufacturer can add more (or better) VRM, power phases, and a better cooler.

I have a GTX 980 Ti reference and I don't overclock it.

Not because I couldn't but because I'm not quite sure about it just like you.

I could overclock the core +250MHz without increasing the core voltage resulting in a boost clock of about 1500MHz.

My heaven benchmark score is almost 2500 and the temperature is at 85°C wich is the reference temperature for the reference model.

The fan is at about 50% under full load. So it does work. But I'd like to read about that PCB as well.

Haven't seen comparisons on these GPUs and cards but typically the reference PCBs are very close to non reference in top overclock on air cooling and standard voltage ranges. Once you water and liquid nitrogen cool especially and put a lot more volts then the special designed PCB really pays off more.

I wouldn't imagine you would even loose 25Mhz.

Thanks.

i am not looking forward for a max possible oc , just i like to oc my stuff a bit.

It will stay in air cooling with a good case so i hope i can get something not too bad.
