Overclocking 980 G1

[velskud12]

I have a GTX 980 G1 Gaming that has a ASIC quality of 65.8% according to GPU-Z. 

 

I want to overclock this card but I don't want to increase its voltage, so my question is at what clock speed should I start overclocking?.

Adding more voltages is out of the picture. I just want an idea of how much this card will overclock without an increase at its voltage, and because I'm noob at overclocking. My PSU is Cooler Master V650  

 

 

thanks

The asic quality isn't that grade I think 1400mhz boost should be a good point to start

I did this last time, I'm unsure about performance gains because I hardly saw any fps gains in AC Syndicate. I forgot to turn the memory clock higher

I would recommend getting the highest stable overclock on the core before u start fiddling around with the memory clock.

it could be ur cpu holding the videocard back in AC Syndicate what are u using as a CPU?

i7-3770 at stock speed. and my mobo also sucks, ECS H77-H2 M3

Well then its probably not holding it back but it was boosting up to something like 1370 or something and 30 mhz is not alot so there is no big preformance gain. as for the voltages us should be able to add some because ur temps are really good 60 degrees is nothing to be worried about

they say they can run the memory clock at 8000mhz, stock is 7000mhz

[Bhav]

Memory clock can only go that high if you have Samsung chips on it. 8262 MHz on my 970s with Sammy chips.

[Curufinwe_wins]

1250 core (which should boost to around 1440-1470) is totally safe and expected to pass.

Likewise 7800 memory is expected to pass. Without Samsung chips you are unlikely to get much above 8000.

I got two sub 70% asic cards running right now at 1292/8000 (1519 max boost).

Good enough for top 5 in world for 2x gpu and 5820k cpu.

Don't worry much about asic.

How can I adjust the boost speed and core speed independently ? as far as I know if I adjust the core it will also adjust the boost speed?, I'm confused now haha

Yes sir it has a samsung memory on it

Then go nuts with over 1000 MHz more vram speed

I've had my cards running 8200 MHz 24/7 without a problem.

O--o-o-k-a-a-y-y ( Stutters ) I'm scared haha. Can I put atleast 900mhz on vram without changing the voltage?. and how many should I add into the core

[Bhav]

Vram doesnt voltage changes. For the GPU try OC 1400 Mhz boost clock, then try increments of 10-15 Mhz until you see artifacts or it crashes and back down to the previous setting.

 

Ive not seen a GM204 that cant do at least 1400 Mhz on stock volts.

[Vellinious]

Even with that low ASIC on stock volts, should probably be able to hit between 1450 and 1500 core.  Make sure the power target slider is at it's maximum, or you'll start to hit the power limit perf cap.

Have GPUz open to the sensors tab during your overclocking test runs, the "PerfCap Reason" line will tell you exactly what's capping the performance at the current settings, and that will allow you to circumvent them for the next run.  Watch for "VOP" and "PWR".  Green is PWR, power limit.  If you're hitting that, that's as far as you'll go....assuming you have the power target slider at it's max.  IF the power target slider is at max, and you're still seeing green in the perfcap reason line, you're as far as you're going to go with that overclock....any further raises will be for nothing, as the card will simply throttle itself to get it back under the power limit. (illustration below)

There is absolutely NOTHING in the stock bios of the Maxwell cards that's going to hurt your card in any way, shape or form.  You could put as much voltage as you want, as much power limit as you want, etc, and still not hurt the card.  Just monitor your temps, and you'll be fine.

Notice where the green shows up in the 2nd to bottom line (PerfCap Reason).  And the corresponding clock drop in the top line?  That's the core throttling to get itself back under the power limit.

You don't, I told you core adjustments that should reach particular boosts.

You can actually mod the boost table in bios, but I generally don't recommend that.

That was thorough explanation, a big thank you!. I did this https://imgur.com/GRpabI9 and ran Middle Earth in-game benchmarks, It didn't give me any artifacts or crashes it just ran and I noticed an fps boost of about 5 fps increase in minimum fps

Hi sir, I did this https://imgur.com/GRpabI9 then I ran Middle earth shadow of mordor in-game benchmarks. No crashes or artifacts, should I add more 500mhz on the memory and 50~80 more on the core?

First thing I'd do is get yourself MSI Afterburner or EVGA's Precision X to overclock with.  And then download GPUz.

I'm using the Gigabyte's OC GURU II, but I also use MSI Afterburner for temps and loads while in-game. is it fine?

I'd only use Afterburner. It OCs just as well, and the fewer programs you use, the better.

I tried this settings then proceeded to play middle earth shadow of mordor, since my monitor's refresh rate is 60. I set the fps limit to 60 via in-game limiter. and after player for I think 5 minutes, my monitor turned brown then followed by a system crash.

Any game I play keeps on crashing with +140 core, 400 memory. GPU-Z says Vrel

ASIC quality only matters for out-of-the-box boost 2.0 performance. NOT for overclocking.

boost 2.0 should boost the performance of the card when it's running colder right?,

When it's within the parameters of the thermal design, yes. So both below the power target and temperature target.

 

Higher ASIC means less voltage, less heat and lower power consumption. Enabling a higher boost clock. This changes radically when you start applying manual overclocking, and makes it rather moot.

 

My MSI 980 Gaming boosts to about 1342mhz, but once it's been playing for a while and reaches >66deg it goes to 1329 where it stabilizes.
