[Official] Nvidia GTX 980 Ti Owners Club - Page 1380

post #13791 of 16160
Hey guys, im alittle late to the party, well anyways, i wanted to know is this ok....

I own a EVGA 980TI SC - Stock cooler now converted with the EVGA hybrid kit.. a while back.

So i know how to overclock my CPU and get me memory upto speed, as i wasnt sure with GPU's i ask you all.

At present im overclocking my EVGA 980TI Hybrid with the following settings

Core Voltage : +50mv
Power Limit : 110
Core Clocks : 160Mhz (1501Mhz)
Mem Clocks : 350Mhz (3859Mhz)
Fan : Auto

What do you think ?

When i go up drastically over 1500Mhz core without any core voltage after 5mins of gameplay or so i will get crash/freezing. My temps are very low, they stay at or about 60c roughly...

I need some advice, is this a respectable overclock or do you think i could squeeze more ? Also since th core voltage has 87mv max. if i use all will it damage the card inthe long run....

Thanks everyone.

I am thinking about buying 1080Ti Hybrid when it comes out, but temperatures don't really matter for me as long as it will really boost/secure my OC.

Thanks in advance!
Every card has many variables so saying reducing the core temp using a hybrid setup will always product above 1500 on core is not possible. What it does do is reduce the core temp which will yield better stability since Maxwell stability decreases with increasing temperature.

IIRC the hybrid kit uses a stock PCB board which your limitations will likely become your vrm or memory cooling. However using a custom bios on the hybrid kit does have a good chance of reaching the 1500 mark but suffice it to say no it's not a sure thing.

With the setup you are using or even the stock cooler the limits on what the stock bios allows through OC software are set to allow you to increase but increase within a safe range. Feel free to max out the voltage and the power slider. See what your max stable clocks are then. If you ensure the VRM, memory and core are running well below the limit you can actually use a custom bios to slightly increase the voltage a little more and achieve even higher clocks.

Hope this give you a little better understanding of what we do here and how to overclock.

Thanks for the fast reply, so presuming i understood it correctly what youve just written i can bump up the voltage to max and it wont damage the card....

And again thank you all.

Correct. The OC software allows you to increase the voltage but keeps it within the safe limits of the chip.

Also after OC'ing, you should do a 3dmark firestrike benchmark and compare your score to others to check that everything is alright.

Hey umm a bit off topic j bought a extreme maximum motherboard, it has an extra 4pin psu plug next to the regular 8pin plug , is it compulsory to plug it ?

it might seem daunting at first but you'll be able to understand a little more of what is happening with your cards.

Ah ok going to do that now.

would that also explain my GPU usage being out of sync?

1440p FFXIV Max Settings.
been like this for the past few hours. I'm used to seeing synced usage.
(doesnt have to be 99-100%, I know how usage of GPU is supposed to work so seeing 99-100% on a not-so-intensive game is normal. would be a greater issue if 100%, haha)

EDIT: which bios should I use as the base? is higher really better, is what Im asking.

tbh, SLI is not my forte though it seems odd the second gpu has a bigger load; is that ONE game or few/many? afa what bios; see which card is a lesser OCer then adjust each bios for that. but no higher isn't always beetteer, less can be more esp when it comes to voltage. (hope that helps)

w/o looking at the manual i'd suspect the 4 pin is cpu and 6 pin pci-e 12 volt.

if you will heavily OC the cpu then yeah id plug the 4 pin in. if you are OCing a SLI setup then consider plugging the 6 pin in.
