Here are my current OC :

GPU Clock = 1227 MHz
Memory Clock = 1878 MHz

I believe 1878 MHz for memory is too low and I should be able to get around 2000 MHZ OC on memory .

Any help and advice are welcome .

If that is your maximun stable OC you wont be able to go any further without increasing voltages.

The problem is that I'm new in overclocking GPU and graphic cards and I think maybe I made some mistake in setting or maybe I should change some setting to be able to achieve higher OC
I can see other users and websites OC memory to 2000 MHz

At 1.212, most of these cards top out at about 1200-1250. I would stick with 1200 locked in with throttle canceled (TDP at 450 watt minimum or GPU Boost will kick in) and the voltage table done like that thread from qc overclockers. Memory overclock gives little. Im at 7400 and 1257 at 60 degrees under stress and 80% fan.

Yeah, oc'ing the mem doesn't really do anything out side of benches tbh. I compared 6000MHz Vs. 8200MHz and the difference in games was only two or three fps maybe.

OR that could be as far as you can go.. I have mine under a full cover waterblock and hit 41C max under load, can't quite get 1250 on the core stable with 1.212v..

Rock solid at 1202mhz 1.150v though in everything even gta5 and witcher 3 with 350w max limit, doesn't pull over 300w in either of them too.

unless you're already doing extreme cooling, that would still scale with much lower temperature. Try at least lowering the temp by 20c more and see how it scales further up smile.gif Mine could still go up at about 3 notches by just letting 20F wind into my window. Obviously that's not something many people would do, just calling it out as temperature IS always a factor.

Doesn't mean it will scale well, or that spending a few extra hundred dollars on watercooling it will make a noticable difference in overclocking it. I dropped temps by 40C and only gained 2-3 13mhz steps at most.. the biggest benefit I saw was lower voltage necessary for the 1202mhz clock and lower power consumption by about 60W because it ran so much cooler. Sometimes the limit is more to do with how well the chip turned out when it was made than how much cooling you can throw at it.

It's stlll a 20% overclock on what was once the fastest single gpu card you could buy, it works rather well considering it's age.

After more testing I think Ive got my final OC settings, core 1163Mhz@1.062v arround 63 C after few hours of GTA V. Is that temp OK? I like to keep temps as low as posible.
BTW Gpu boost sucks, befere i decided to OC it was boosting my core to 1150Mhz@1.162v and temps were above 70.

I guess I would call that gain a progress, regardless how small it was. I was just trying to answer the Y/N rather than how much more you could get. The 2-3 steps you got is about the same ballpark I had on the same voltage/frequency. It scales more as you go up - at least on a few 780 ti's i've had. Then again, any gain isn't linear with temp and little temp delta doesn't really make much of a difference, unless we're talking about multiples of, say 20s C for instance. Think i recall someone saying it only takes water cooling to reach 1500mhz-ish yet didn't disclose the water temp...could be 40c or could be 5c. There's so much ambiguity in this world, esp when marketing people step in wink.gif
