Overclocking my gaming x

[Davidf4e]

I just started to overclock my gaming x and put punched in some numbers and it works. What does core voltage do? how far should i do core clock? memory clock does it do anything useful?

do core clock first then memory then run stress test like heaven unigene or valleu unigene. keep testing until it is stable

finally up the core voltage and then play around with memory and core again

Just for starters: 

 

Set Power limit as far as you can get it to. Don't starve the card for power, or else the whole OC is meaningless. This is assuming your PSU is not garbage. Tier 3 and above. 

 

First you overclock the core. Go up until it starts to throw artifacts or you have a driver crash, since you are in Pascal micro architecture, you can start at 150Mhz offset and further on pushing extra 25 Mhz. You should be able to reach the first 150Mhz without touching anything else whatsoever. 

 

Secondly, once it crashes, or throws artifacts, you pump the core voltage up in 0.05 steps. Pascal simply scales badly with core voltage plus Nvidia set a limit and you cant go past 1.093V if i recall correctly. 

 

Now you should have found your sweet spot in core. Probably in the 2000 ~ 2100Mhz area. You can start pumping VRAM clock. it varies from brand to brand, but you can start at 400Mhz offset and from there increase/decrease 50Mhz steps until artifacts start popping up. 

 

After a few tries you should get quite approximately the maximum OC under your particular conditions. (Cooling, silicon lottery, etc).

GPU overclocking is not the same as CPU overclocking, there's a lot more error tolerance and correction so errors may occur later than sooner and may not be fixeable by pumping more voltage. If anything it will increase heat production so, there you have the all time trade off Heat Vs Performance. It makes no sense to increase voltage with a 65Mhz offset on core, don't start like this with GPU's. 

 

The ultimate test is gaming. I had previously made it through several hours of Unigine but later on crashed on Crysis, or Shadows of mordor, or whatever was i playing in that particular timeframe.
