The GTX 980 Ti owners thread.

I've had mine for 5 months now, I primarily use MadVR, it's amazing just how much a resource hog it is. The moment you start chroma double it brings the GPU to its knees.

Yeah, it's to keep power consumption and heat down when extra power isn't necessary. I think you can turn the feature off in Nvidia control panel by changing "power management" to "prefer maximum performance" from "adaptive", though I wouldn't recommend it.

my refresh rate is 85hz on my monitor. I'm thinking more of the lines of gpu boost 2 and adaptive power is working much better in the ti's

my 970 or 680s never down clocked like this in fact adaptive power had little affect on clock speed set in AB and would only stop down clocking to low power states.

V sync never effected clocks.

The only way to hit the high clocks is to change res to 4K in some games then it boosts to 1540. When it's doing its dynamic clocking it's running at about 1160 or lower depends on the game.

do you guys think these variations in speed have been set at a driver level?

The card is not throttling as temps not going above 44C G10 with Kraken x31 fitted.

I found this a bit worrying at first but games are running smooth as silk Really impressed with this card @1440 will be going SLI at some point

This doesn't sound right to me. You should be getting your boost clock in most, if not all games. However, a boost of 1540? That must be an OC?

What card are you using?

Edit: you're using a Classy, right? Those clocks are too low, something isn't right.
 
I thought that going from a stock reference cooler to a much more efficient MK-26 cooler would make the card boost much higher and while the temps has gone waaayyyy down.. we are talking 40 when gaming Heroes of the storm, compared to 84-85 before with the reference cooler, the boost clock is the exact same.. I guess the Bios asus uses for their reference cards are a bit boring and dull. Also i cannot get it past the 1450 mark as it wont last more than a minute or 2 with 1500 on the core sadly.

I've settled on mine around 1480, which drops to around 1450 during gaming. Not massively disappointed that it wont clock much higher than 1500 as the difference in benchmarks I tested didn't really show an improvement worthwhile IMO. In fact even running it bone stock at 1380 it's still very capable.

I've basically set it up with 3 profiles in AB:

1. 1500/4000 +110% power, this will boost to around 1500-1515 in benchmarks and stuff but wont hold up in games.
2. 1450/3900 100% power, this will boost anywhere between 1450-1480 depending on the game, seems fairly stable so far.
3. 1380/3600 Bone stock.

Guys, I have purchased a second 980ti for the set up yesterday - the Gigabyte Extreme waterforce edition. Everything is great performance and temp wise but I can hear a water flowing through the radiator on odd occasions.
It scares the **** out of me as at first I thought it started leaking. Cold this be some air in it? Is this something I should worry about?
Card sits in top slot with radiator above it in a rear exhaust slot. Pipes are at the top position of the rad. Should I turn upside down?
Emailed gigabyte but no response due to bank holidays.
Card was new but had no warranty with it so a bit worried.

Rock the case a little. Gently. Whilst on.

Likely a bit of air..just needs to come to the top.
 
I have an inno3D reference 980 Ti - Got +250 on the core and +300 on the mem.

Hoping to find another one so I can SLI but damn are they hard to get, might have to settle on a Zotac, might bug me though!
 
So I've been attempting OC on my 980Ti SC+ and got to a point where it locked my system.

I managed to get stable in Heaven/CS/H1z1 with EVGA 980Ti SC+ @ 1500/3954

It locked up at 1520, I've not touched the voltage yet (just set to 110% Power Target).

What are the next steps to go higher?
Do i start to increase the voltage to get past 1520? (temp is 50c)

Thanks!

I doubt temp is 50c at full load unless you live in Antarctic.

Im sick of overclokcing for the time being, I have tried multiple bios' from places like this http://www.overclock.net/t/1411500/official-evga-classified-k-ngp-n-owners-club but none seem to be 100% stable for gaming. Im just going to flash back to my standard bios and leave it at stock i think.

It annoys the hell out of me that you can buy what you expect is a premium product and both (I RMAd the first 980Ti classy because it throttled at 66c all the time) cannot overclock as well as cheaper or even reference models. Companies should properly test to see what the highest overclock is then sell the crap ones cheap and the good ones expensive

Have you tried extracting the original bios and modifying that then flashing it back? Make sure to make a backup of your original bios though. Even if you have a backup bios switch on the card just to be safe.
