ASUS GTX 780 Ti's boost clock is 1020MHz?

JanTemplar · Jan 20, 2014

I was playing Tomb Raider (Ultra settings, resolution: 1600*900, Vsync On(60 FPS) and Tessfx hair on) with EVGA precision monitoring and i noticed my GPU's temp is usually around 82, at 1020MHz clock boost and gpu usage sometimes goes near 100%!!! after that i surfed internet a little bit, all I've found was, GTX 780 Ti runs Tomb Raider at 1980*1020, around 130 FPS!
Why GTX 780 Ti base clock is 875MHz and Boost clock is 928MHz, but my gpu sometimes goes on 1020MHz, What is this???
CPU: core i7, 4770k, 3.5GHz and Cooler Silver Arrow SBE Extreme
Mainboard: asus Z87 deluxe
Memory: 2*4 GB Vengeance DDR3, 2133

and i also find GTX780TI-DC2OC-3GD5 - Asus boost clock is 1020MHz! Not GTX 780 Ti.

Thanks for reading...I'm waiting

well is your gtx 780ti a reference card, or is made by another manufacturer, different manufacters tend to put different clock speeds on their gfx cards.

huh? The mhz jumps up because of gpu boost.

JanTemplar · Jan 20, 2014

All i know is this:
ASUS GTX 780 Ti 3 GDDR5, how can i understand it is made by another manufacture and which one?

JanTemplar · Jan 20, 2014

You mean it jumps up above boost clock? on EVGA precision, it says my boost clock is 1020MHz, but on the sites I've surfed, all of them are saying ASUS GTX 780 Ti boost clock is 928MHz! and ASUS GTX 780 TI directcu ii oc boost clock is 1020MHz

azzazel_99 · Jan 20, 2014

The card is made by asus......1020mhz is the boost clock.....Everything is completely normal with that i dont understand the issue.

GPU boost 2.0 that succeeded Gpu boost 1.0, I have the same card and it's boost's to 1020 and then goes down to 1006 or lower depending on the game.

Because your gaming at such a low resolution you will might get max boost all the time, I don't because i'm using 1440p.

azzazel_99 · Jan 20, 2014

That doesnt make sense. The more stressed your gpu (1440p) your clock would stay higher not lower. The boost depends on the work load being called upon from the gpu. More load higher clock. Less load lower clocks.

mr91 · Jan 20, 2014

Unfortunately not because of power and temperature limits - I would have to increase temperature and or power limits to maintain the boost.
I can also overclock if I increase the power and temperature targets. Gpu boost reduces voltage which lowers boost clock in response to increase temperature and possibly power limit. gpu boost 2 is quite complicated.

Sometimes if the game is not demanding my 780 ti will lower it's clock speed

Play a game like Crysis 3 max settings and you will see your boost clock go down however I never owned a 780 ti classified so I'm not sure how it works.

How is the 780 ti classified btw?

azzazel_99 · Jan 20, 2014

My card has no issues with dropping clocks. It never gets over 65 celsius and sits at 1020mhz. Doesnt ever drop while playing. Now if im playing something less demanding thats a dif story but I've overclocked it too 1200mhz with same results. No clock dropping.

azzazel_99 :

because it's staying below the threshold temperature where the clock would start to reduce, which would be around 80C. All cards are different, with different cooling solutions and fan speeds, different base clocks and boost clocks.

mr91 · Jan 20, 2014

The classified has a base clock of 1020 and a max boost of 1085 so that means you're not getting any boost at stock however 1200 is a nice overclock.

The Classified cards have a good reputation for overclocking...

What is your ASIC qaulity, You can check with gpuz.

azzazel_99 · Jan 20, 2014

My point. Long as you arent hitting that "max" temp your clock will not drop. More load higher clocks. Less load normal clocks.

mr91 · Jan 20, 2014

The boost clock will go down only if I play games like dishonored or devil may cry that don't demand too much gpu power or I turn down my settings in other games...

When I play these games @ 1440p my gpu is running at 600-800 mhz because the games don't need anymore and Nvidia cards have power saving features.

I'm using a 1440p monitor so when I play games like Crysis 3 or metro LL my gpu is pushed hard. If you hit the max temp the clock will go down however if you reach your max power the clock will also go down.

The classified is different because it's has better cooling and is supposed to use power more efficiently however you are probably gaming at 1080p that's why your card isn't breaking a sweat in most scenario's

If you play at 1080p it's a different story because the gpu isn't pushed as hard. Based on my observation the gpu uses about 25 more watts of power when playing demanding games @ 1440

Did you find your Asic? my Asic is just above 73

I've seen you in different forums - Do you see a huge performance increase with your upgrade?

azzazel_99 · Jan 20, 2014

Yes. I only play ac4 and bf4 right now but I can set res scale to 200 percent in bf4 and it still runs great. Yes I play at 1080p because 1440p monitors arent worth the price they cost. At least not a good quality 27 inch. 1080p still looks great.

mr91 · Jan 21, 2014

The 780 ti is a great card ! High Quality 1440p monitors are expensive however they are a lot cheaper then 4k monitors.

JanTemplar · Jan 21, 2014

Yes i noticed too, when a game is not much of a hungry one, GPU usage drops so as MHz, for me it goes on 50% and 700MHz, but when a game like crysis 3 you mentioned, for me it stocks on 1020MHz and 70,80% and sometimes 99% !!
Here's a question, how much resolution influence on performance? because i didn't see any noticeable performance advantage when I was playing 1600*900, and not 1080p. but 1440p, it seems it just fits to it!! i don't know how but it's true, this card shows itself on higher resolutions!!
