Hey guys, I'm pretty new to overclocking. I've been building PC's and gaming for over a decade so I think it's about time I start overclocking.
I have a 4790K OC'd to 4.5GHz, and I have two ASUS GTX 780 OC Edition cards which I am trying to overclock a little more.
My CPU doesn't seem to get maxed out very often so I don't feel like it really needs more OC, but the GPU's do get maxed out in some games, especially since I'm running 2560x1440.
I tried giving it +100MHz on the core and +200MHz on the memory, along with bumping the power target to 103%, temperature target of 83°C. This was fairly successful, and gave me about 1000 extra points in Firestrike. I thought the OC was stable, but after driving around like a mad man for an hour or two in GTA 5 I crashed the system. The system was on with this OC for at least 20 hours.
Where did I go wrong? What should I change first?
Save a OC profile for your CPU, set the CPU back to stock, set the gfx memory back to stock, set core clock to +50Mhz, increase power target to 110%, run Heaven Benchmark Maxed Out, 3 loops. If thats stable increase by an additional 25Mhz, if not increase the voltage by a small amount and repeat.
Once you find the max stable core clock in heaven, do the same for the memory. Then test the card/s in multiple games and benchmarks, once your sure the card/s are stable load the CPU's OC Profile and test again.
Well at least that is where I would start.

Thank you Nate, that is very helpful!
Most of the time I hear "just try little increments" but there never seems to be a order as to which part to increment first. That definitely gives me something to go off of. I'll post again when I get a good result.
I managed to get +175MHz on core and +150MHz on memory, though I think I can easily get them higher. I haven't messed with overvoltage yet, I just don't have much time after work before I have to sleep :(
At the very least I've improved the stability of my frame rate in pretty much every game! GTA 5 no longer has those nasty drops when I drive through the woods super fast.
If you right click the top left hand corner of gpu-z you can read your gpu's ASIC quality - if >80 you're in golden card territory and ocs wiil be high, below say 50 achieving a good oc is an uphill battle.

Thanks for that tip, I found that my top card is around 66.2% and the bottom card is around 71.7% so I assume I shouldn't be able to OC way crazy.
