470 OC questions

post #1 of 5
Thread Starter 
Hey guys need some reference for my card. It's not an official 470 but an EVGA 465 SC unlocked to a GTX 470. I finally used Afturburner to do some overclocking, was using Precision but was running into stability issues at low overclock.

I currently have the card set at 750 Core and 1681 Memory @ 1.05 v. Original volt was 0.95. Stable using OCCT for 10 min.

Using HDMonitor it is showing the card using a max of 1.01 volts. Can I reduce the overvolt to 1.01 without issue? Will this make a difference or does the card simply use 1.01 and the extra .04 v will not have an effect on heat?

This is my biggest question, as I would like to see if I cant bump the Memory clocks up a little bit as well, but still want to keep min voltage for heat control.

Still on stock cooler, heavy load maxes ~ 82'c with aggressive auto fan. I know I can take it higher but no reason to just yet.

Don't expect much out of those unlocked 465s. I had a MSI gold edition and it only went to about what you're getting. Decided to sell it almost immediately and get an actual 470.

Not too worried about that. I just wanted to know if the card reads as using 1.01 volts if that is exactly what I can set the overvolt to and if that will have an actual impact on temperature.

Just for info...

The slight changes in voltage made no difference to the cooling. Afturburner however would not allow me to set to exact voltage used... I wanted 1001 and it would set either 1000 or 1015.

Yup, the voltage goes in steps. That much of a change isn't going to have a huge impact on temps at that clock speed. Might as well just juice it up to the full 1.087 and see what you can get.
Finally an update
