Help me out with 770 overclocking..

[Mr Paul]

Well I've setup Afterburner to provide +12 mV voltage (max) 111% power (max) and 95°C temp limit (max).

The best core overclock I can seem to get is around +55 Mhz on the core and +100 Mhz on the memory.

This gives me a core speed of 1140 Mhz, boost of 1192Mhz and K Boost of 1254Mhz.

During Heaven I only see a max of 62°C and a max of 77% power.

ASIC quality is 84.2%.

Seeing as during Heaven I am no where near reaching the power or temp limit, what is stopping increasing the core clock? Simply a not very good one?

Sounds like you're out of volts! The ability to push volts higher entirely depends which 770 you have...

~1250 Doesn't sound to bad to me if im honest, even if you could get another 100 on the core you'd only see a few FPS different in game if that

That's the max it's an MSI 770 gamer OC.

Is there any way to set more? Or is nVidia gimped it?

What the hell lol

Afaik thats about your lot with 770's. Only a select few models of 770 had the ability to over volt and iirc the MSI Gaming edition wasn't one of them.

As said above though, 1250mhz is still a healthy clock, even with volts you'd maybe only manage another 100mhz before you needed to start looking at a custom bios due to the power limit.

Enjoy the card at its current OC

i have msi gamer 770 oc 4 gig version thats about right boost clock 1267 for me if i go higher its not stable (need more volts, but they are locked) , memory clocks very well i can go up to around 8070 mhz but i left it on 8000.

 

[Mr Paul]

How do I go about modding the BIOS for more volts?

don't think there is modded bios for 770 im afraid , correct me if im wrong
