Hey there,

I just wanted to keep this short and quick so there's not a bunch to read

I just got my new PC-

Specs:
CPU: INTEL® Core™ i7-5820K Six-Core 3.30 GHz
FAN: Corsair Hydro Series H55 Quiet Liquid Cooling system w/ 120mm Radiator
MEMORY: 16GB (4x4GB) DDR4/2133mhz Quad Channel Memory
MOTHERBOARD: MSI X99S SLI Plus INTEL X99 Chipset
POWERSUPPLY: 700 Watts Power Supplies
VIDEO: NVIDIA GeForce GTX 980 4GB 16X PCIe 3.0 Video Card

-and I was wondering what overclock settings you guys would recommend for my GPU. I'm not looking for an extreme OC. If there is any additional information needed please let me know

Any recommendations?

I'm using MSI Afterburner for overclocking


Thanks
 
Which 980 ? Some do better than others and from what I have seen with the 970's, the MSI and Gigbayte do the best due to superior PCB cooling. Haven't seen a 980 tear down yet, just going by the componentry on the 970s from the bit-tech review .... so merely an assumption on my part till such can be confirmed. They did a Gigabyte tear down

Can't help you much with the GPU clock, but I can tell you the Samsung memory used on both the 970 and 980 is an absolute overclocking dream.

Of course - It's hit and miss, but most of them I have seen managed to get to 7700-7800MHz effective. Quite a fair amount also managed to get to a whopping 8GHz. Not half bad that. The 980 generally has additional phases versus the 970 which may also aid in overclocking.
Interestingly, memory frequency doesn't tend to affect things all that much. To give you an example - I gained around 1fps for every 400MHz jump in Heaven. Ie. 7400 = 58.6, 7800 = 59.8. Roughly.

Upping the GPU clock by around 50-100MHz and then running a Unigine Heaven bench each time should give you some indication of how far you can go.
Set the power limit to 110-120. Both work, but at least on my 970 the most I've seen it ever go through Heaven, Valley and Crysis 3 is 108%, so I've dropped mine down to 110 (That'll be Heaven for the 108%, seemingly the most demanding out of the three).

Finally, the voltage is the tricky one. The 970 and 980 are somewhat different, naturally, but both overclock fairly similarly - In that, both are beasts and go far higher than their shipped settings. It's a silicon lottery, evidently mine doesn't need much at all, the out-of-the-box was set at 1175mV and the only single reason I've upped that to 1200 is due to the reported max voltage use being exactly 1175 through a 3DMark11 run. Other than that it was stable and no dips in memory or core clocks.
Essentially what I'm getting at here is that it depends, the 980 voltages are likely to be a little different but their required increase after an overclock may be equally as minuscule.

Nvidia really hit a winner when it comes to overclocking these things.

Yh I have an MSI GTX 980
