Gpu Boost

[Demonhax]

Hello. 

I have a Gainward Gtx 770, And i was wondering how the Gpu boost works?
The max boost speed i can come up to is around 1162 Mhz.
I've heard that the card will boost itself up to as much as it can if i give it enough cooling and keep it at a low temp.

But it seem to stay at that speed even with low temps.

You will hit a limit regardless of heat.

If your temp is good enough, you can raise the voltage to increase the boost clock. Mine was showing 993MHz boost and when I raised my voltage to +37, it boosted up to 1045 for me.

Will that take out my warranty of the card?

No, as long you don't mess with their BIOS they put in the card. Depends on brands most will void warranty if you take off the cooling solutions (Fans; ACX, Blower style etc etc) that came with the card, some do not void; like EVGA, I think for some cooling solutions they allowed. You void the warranty if you modified the BIOS on the card, such as ''Voltage Mod'', any modifications for the card's BIOS are prohibited. You can use them, but you will void the warranty, so use them at your own risk.

 

P.S>If you like to know; the max voltage increment is +38 on my Precision X.

 

With Voltage mod BIOS, it let it bypassed the limit on your max voltage +38 to probably +50 or something (someone with voltage mod please correct me on this.).

So, I would just have to adjust the Voltage to get the card to boost more?

Nothing else?

When im trying to set up the voltage a bit. I only get to max 12+
Why?

Why?

That's the max for 770. 780 is +38 mV

Ah I should've know that you have 770, Honestly increasing Core clock gives around 2-3 FPS depending on how far you're able to overclock, not worth it. In my opinion, just increase Power Target to max and voltage to max, Temperature at 85C, leave it all at that, it's still a great card, and the boost clock will be higher. Make sure your temp stays below 85C so that way it won't throttle. By throttle, I mean it will downclocked till your temp is at an acceptable temperature.

It starts to downclock at 80c; at least the 780 does.

So, increasing the temp target doesn't prevent that?

 Nope.
