Gpu oc core question

blasterbolt · 28 Feb 2015 at 11:53

At the min i can oc my card with afterburner to 140 core 300 mem 40 volts and run benchtests no probs top card in games runs at 75 in heaven though it hits 85 after 10 mins.

As soon as I start a game it crashs with in 10-20 mins of running. BF4 runs nps at 130 core and 300 mem yet DAI crashs with in a few mins.

Now I was wondering about taking the plunge " pun intended

" into water cooling. If I had the same gpus water cooled would I be able to push the core and mem past the 140 and would they be stable in games or would they just crash like they do with the stock cooler?

Hi
Thier is no way of telling if you can get the clocks you want by going under water.
It is still down to the silicon lottery, Also its a lot £££ for water cooling.
But saying that most get a good bit more from water.
Its a big gamble price per performance.

Yea I know that's the conundrum. Well I will be keeping my swift monitor for a good few years so if I can push the 980s to get it to 120 fps in bf4 then I would be happy to invest in water.

Would be gutted though if 130 on the core was the most it would hit.

You don't mention what card(s) you have (make / model) if high end factory overclocked then there might not be a lot of overclocking room left and the chances are the cooler will be pretty decent and changing it may not net you much in the way of results other than a cooler / quieter running rig. If base model at stock clocks with a low end cooler then you may get more stable / higher clocks but nothing is guaranteed.

Not watercooling but I replaced the stock cooler on my Asus DirectCUII GTX680 (top end stock cooler) with a Prolimatech MK-26 with 2 x 140 fans and this made no difference to my max overclock at all, but I sure appreciate the near silence in my case when the GPU is at full load (fans never exceed 40%).

Opps how I forgot to mention that the cards are 2 kaf2 gtx 980 soc I dont know :confused:

Well atm to try keep the cards cool I have 2 120m fans in the front in pull 2 140 fans on the rad for the cpu on the top in push and 1 140m fan for the rear slot in pull.Also I have a 120m high pressure fan right next to the gpus blowing side ways on them . So needless to say its a bit louder then I would like.

I had a chat with a member of staff at OC yesterday and they infromed me that these cards aint meant to be overclocked more then they are . So with that in mind i think watercooling them as you say might not get any more speed out of them. Shame really but they still manage to push 70-100 fps in BF4 on ultra in 2k so I cant really complain
