What temps should i be looking for (less than 80C?)
With the new GPU boost i hear that the numbers float around a range? Lets say i OC to 2000, would it realistically be more like 1950-2000?
As far as testing the OC, how will i know it's stable? I know the OC mode for this card, using the MSI software can push it up to 1791 i believe, but I know this card can push out more!!
Sorry for the newbie questions, just would like to get a nice grasp before I start messing with it tomorrow.
Its really simple, not much more different from cpu overclocking. Most 1070's hit around 2025mhz oc stable. and ram about 400+ mhz stable but every card is different. just install the card and the latest drivers and then get msi afterburner, for programs Heaven or Valley are great choices, some like Furmark and that works just fine too but i simply prefer the latter. run the card for about 10 minutes first and get a baseline mark of your base clock speed and base temp, keeping at or preferably under 80c is key and if the temp does raise above you can set your own fan curve to cool it better, but for the base testing leave it stock until you find your general overclocking limit. To start overclocking there are 2 ways, you can either do small increments of 50mhz and then test or you can go big and start right off the bat at +200 and test, both ways still require work and tweaking, i personally do 50mhz increments. If you really want to push the card as far as you can boost the voltage all the way up. i know that sounds bad but it maxes out super fast at a rather low 1.25v and that is totally fine under load, if you do this do another baseline measurement and see what you hit and so forth, now from this point begin the 50mhz increases, increase 50mhz then do a 5 to 10 min baseline run of the benchmark program and just look for general instability or crashes or artifacts, artifacts will be very noticeable random tears/acting up on the screen, its hard to explain but it is very noticeable. Once you hit the point of instability begin lowering your clocks in about 10mhz increments and continue testing until you find the stable point. If you only want to do a core clock oc this is where you would now begin your extended test and generally you want to leave it running for a few hours at least, overnight is the option most people choose. if it crashes or shows instability again lower some more. If you want to do memory overclocking begin with 50mhz to 100mhz boosts and testing the same as before, quick 5 to 10 min tests until you hit instability, from there just drop it down, i find memory to overclock alot farther, with my 960's running 400mhz+ zero issues, so dont be afraid if you think its too much after a point, good memory modules will oc far. once you finally find the point of stability begin your extended stress test. if you hit instability at this point it is a choice whether you want to lower memory or core, both pull generally the same power, core clock will generally net you more fps so lowering the memory clock is what most will do and is just fine. once you have tested for a extended period and its stable, congrats, you have successfully overclocked your gpu, at this point if temps are a bit too high for your liking you can make your own fan curve within afterburner but msi's cards have shown very solid stock results even when overclocked so you probably wont have to touch it unless you want too. at this point just look out while gaming for any artifacts, sometimes the card will pass stress testing only to artifact or lock up on games, in that case just go back in and lower a clock and play again and see if it happens. after the first 2 days of tweaking you are pretty much set forever, just make sure to save the oc profile in afterburner just in case and your done. i hope this helps you a bit, i know its not the best organized paragraph haha but its something.
enjoy and happy overclocking, and questions feel free to ask away.
