Overclocking help?

[CaffienatedBovine]

I was wondering if anyone who was experienced with overclocking could help me find a sweet spot between stability and performance. I've watched a million tutorials but I think I just need some one on one help. I have skype and google hangouts whatever is more convenient (both can screen share).

 

Edit: GPU overclocking on my reference GTX 980.

It will all depend on how good of a chip you got, and which CPU specifically. For example for Haswell generally the sweet spot is the highest stable clock you can get on 1.25V

I have a devil's canyon CPU but more specifically I mean GPU overclocking (just anyone willing to spend some time helping me find the right overclock). For anybody wondering it is a GTX 980.

Most 980s can get the shit overclocked out of them, try it the easy way first by turning power limit up all the way and increasing core clock gradually until it becomes unstable, then going back to the last stable core clock OC. See if you're happy with what you achieve yourself and if you're not then maybe we can see what can happen with more deeper tweaks.

Here is the guide I give eveyone (I really need to write this down)

• Download a overclocking program. I recommend MSi Afterburner, but you can also use EVGA Precision X. Depending on your card manufacture, you can also use Asus GPU Tweak.
• Increase the clockspeed with 5-10MHz
• Test for stability using Unigin Heaven (or Valley) or a graphics heavy game (Crysis 3, Battlefield 4, Metro: Last Light etc.)
• If stable, repeat.
• If unstable, raise the core voltage or power limite
• When stable, repeat untill you hit around 90°C on the core.
• You can also overclock the memory, but it really doesn't do much.
• Raise the memory clock with 20-30MHz
• Test for stability (same as before)
• When unstable, scale back to the last stable setting.

Remember, don't overclock the memory and the GPU at the same time. That will only lead to more points of failure.

Overclock one, and then the other. 

Unfortunatly, I'm not really able to help you over Skype, but there might be someone on the unofficiall TS that can help you-

One set of clocks isn't guaranteed to work on another card, each card is different so you'll see different results.

 

Firstly, you'll want some overclocking software, EVGA PrecisionX would be my recommendation.

Crank the power target up is the first thing to do.

Overclock the memory then when it becomes unstable find the sweet spot that it can run at without failing (See note 1)

Then move onto the core and do the same thing.

 

Overclocking the memory and then the core generally yields a better frame rate increase compared to overclocking the core then the memory.

 

Note 1: To test short term stability you'll want to use EVGA OCScanner (there's probably others but I recommend this one), this is how you find out if the card can cope or not.

Note 2: After you've got as high as you can (or want) you'll want to run a benchmark (such as Unigine Heaven) to test long term stability, if it goes through without the display blanking out or any artifacts appearing then you're good to go. If not, you'll need to lower the clocks a touch.

These were my results:

Unigine Valley

+0 67.1fps

+50 70.2fps

+100 69.7fps

+150 71.0fps

+200 72.0fps

+250 Unstable

+220 71.7fps

+230 71.7fps

 

230 I saw a few glitches so I took it back to 220. Will in-game performance be as negligible as in Valley? What else could I do to boost performance(fan curve, core voltage, memory clock)?

Seeing as though +200 gave you the best performance stick with +200. A 5FPS gain in Valley is actually quite good and in a lot of games you'll get more then that. Stick with it for now, since 980 is still a great performer and better to have it run cooler and quieter so it will last longer then squeeze out performance you don't exactly need that much
