Best way to start GPU ocing?

[Pyromaniac225]

So rn I have my GTX 780 running at 1 GHz. It runs fine and runs about ~14 C above ambient at idle (~39 C total). Of course, I want all the JiggaHertz. So I'm just wondering where to start.

 

I heard from someone I should start by turning up the core voltage to 1.3 volts?

 

I know the rest about turning up by 20 MHz and running a stresstest then rinse n repeat until it crashes.

The only thing I'm really unsure about is the Voltage? Is 1.3 Volts safe?

 

I'm new to GPU overclocking, so any info would be appreciated!

#1 thing you NEVER do, is just make out the Voltage all willy nilly as some cards will respond horribly to added voltage. Start with the power target maxed out and overclock the core first till you get your first driver crash then start increasing the core voltage up to 1.212v if your on air. 1.3v is water-cooled required as temps are not easy to control on air. Once you get done with the core do the memory till your get a driver crash.

You overclock kepler in steps of +13MHz its how their boost table works.

No, don't crank the voltage first! Bump the Clock / Memory Clock, stress test it until it crashes then bump the voltage slowly and stress test it again, then keep increasing the clock speed (if you want) or just downclock to previous stable clock if you don't want to increase the voltage.

Does everything here look good?

Should my card be clocking up to 1320 Mhz? even if for just a second?

 

 

My settings are as follows (because for some reason puush won't show the program I'm using in the screenshots...)

Core Clock: 1201 MhZ

Max voltage: 1.212 V

Mem Clock: 6008 Mhz

Power Target: 110%

GPU Temp Target: 85 C

Fan Power: 80%

 

During my benchmark with above settings in Valley Benchmark I recorded these

Max core clock: 1320 Mhz

Average Core clock: 1058 Mhz

Max Temp: 71 C

Max voltage: 1.175 V (shouldn't it be hitting 1.212 V?)

 

Does this seem right? Are there other things I should be doing? Is there anything I'm doing wrong?

 

Thanks

Still okay, but do you experience Artifact or crashes? If you do, you can overvolt it further (watch temperature) or downclock to previous stable clock.

No crashes or artifacts. I did have a crash before I bumped up the voltage, but after I added ~37 mV it didn't crash.

Then you're good, you can bump the clock speed even further or stay at that speed if you feel satisfied already.

Seems I've hit a wall, it won't let my GPU use past 1175 mV even though I have it set to 1.212 V, probably due to the fact that I can't go past 110% power target.

Probably, if you're done then you can save the overclock to Profile slot (if you're using MSI Afterburner) and set overclock during startup.

I'm not, funny thing though. I have it set to run at 1162 MHz, but in-game it runs at like 1280 MHz.

Whoa that's weird.

What should I do for memory clock? The same thing?

Memory I would increase in steps of 5mhz and bench after each run. Plus the 1162 and it going to 1280Mhz is GPU Boost 2.0 doing what its supposed to.

just curious what was your valley score on extreme hd 1080p?

I'll run it again soon and tell you.

Same procedure, increase it slowly and stress test it.
