***GTX 780 Ti Owners Thread***

[Silent_Scone]

50c underload is very impressive my bottom card can just about hit that under load when all 3 cards are in use, although silent

Thanks for comments on the rig

Yah it will do . How's the classy cooler for noise? I've never owned an ACX card.

I had the oldskool blower design on my 680 Classy

Mine wasn't too loud (quieter than 7990) and ran in the low 70s.

Also, my 780Ti should be here next week

Ok so on stock cooler in my HTPC case my Asus GTX 780 Ti seems stable on +124mhz core, +248mhz memory = 1000mhz core & 2000mhz memory [wrong: 3500 + 248 = 3748mhz memory x2 DDR]. Score on Heaven 4.0 went up by about 300. Will run 3D mark Firestrike and see if it reaches 10,000 (just under at stock).

Seem to have got lucky this time (after my last 2 GPU and CPU overclocking failures...)

Look's like I found the limit of me' first Ti Classified. No shutdowns here. Using Win 8.1, Skynet BIOS, EVBOT, Valley in a 2560x1440 windows maxed out on a 4K monitor.

So, she will do 1306 MHz at 1.212v, 1472 MHz at 1.4v (with some artifacting), it took up to 1.475v to get rid of almost all the artifacting, then 1.5v got me 1502 MHz. At 1515 MHz, she gave up the goose! 1.5v is the limit of my comfort, but I should be able to get a 1502 MHz Valley run to pass once I get my CPU tuned in.

Spoiler

BTW my Kill-A-Watt was showing my 780Ti classified was using ~460 watts after rest of system load was deducted.

I was looking at getting two 780Ti in particular the windforce ones.
http://www.overclockers.co.uk/showproduct.php?prodid=GX-129-GI&groupid=701&catid=1914&subcat=1402

Could someone tell what power connecters they need, is it 8pin and 6pin or two 8 pins.

 

[whyscotty]

2 X 8 pin

"The 11.5in-long WindForce 3X embodies three 75mm fans sat on top of a card-wide heatsink connected to six heatpipes - two 8mm and four 6mm
that run through a large copper insert. The heatsink is divided into two sections, with the gap between the pair enabling airflow to pass on through
to the PCB area underneath, and Gigabyte places six thermal pads/strips to help cool the 12 memory chips and VRMs.
As usual for truly high-end cards, two 8-pin connectors provide the maximum available board power"

Vega that's impressive. Hope someone unlocks 1.4v for ref cards or at the very least 1.3v

Am I right in thinking the + value for the memory offset on EVGA precision is to the shader speed, since that is the thing that seems different between the stock and factory OC GTX 780Tis? They all say 7000mhz for the memory.

The monitor on EVGA precision says ~3000mhz for the memory at the bottom of the application, so that is nothing to do with my my shader speed (1752 + 224mhz offset)?

[EDIT - In answer to my own question: "+ mem" offset in EVGA Precision affects memory, which at stock is 3500mhz (x2 for DDR to give the advertised 7000mhz memory speed). Shader speed seems to stay at 1:4 ratio with memory, so 1752 at stock, 1874 mhz at my overclocked settings of 7496mhz memory i.e. It rises by half the "+ mem" offset value.]

Is the EVGA Models the only models which are 10.5 Inches in length?

Reason I ask is because my EVGA Hadron Air only supports cards up to 10.5 inches! I would also think it would be better to go with the card with the blower cooler ( http://bit.ly/1eA8u8C ) because with my case being so small it would be better to extract the warm air.

 

[Parabellum]

Nice clocking Vega 1472 MHz @ 1.4v what cooling solution are you using & what temps are you getting @ 1.4v

 

[Silent_Scone]

I'm guessing it's not air

All the standard reference cooler GTX 780 Ti cards should be 10.5"

The cooler works well even for a moderate overclock (see my post above) and is great in an HTPC small case as it exhausts all the hot air, helping your CPU overclock / stability. You can see how it sits in my case on the motherboard in these 2 images (links) but it does stick out 1-2 cm over the back of the standard ATX motherboard.

Update: 3Dmark Firestrike - 10672 @ 1000mhz core and 3748mhz x2 memory = 7496mhz

Your memory doesn't seem to be overclocked on that image MjFrosty. Is that because of dynamic clocking with not enough demand on the 3 cards from Bioshock Infinite (which ran fine on my 680 GTX)? Or are you just running at stock to burn in your thermal paste on your new watercooling blocks?

[Also can you check if my post 7 above this (12/1/14 @ 19:41) is correct regarding memory and shader clocks now I have edited it?] Thanks

Thanks how do you find it with noise when gaming and then not gaming?

I am thinking on going with EVGA I presume the blower cooler is the same on all reference cards are has EVGA modified there cooler?

Well that's a lot more impressive than my Ti classified matey. I'm not having a great time with mine to be honest.

At 1.212v mine is bench stable at 1220Mhz but requires 1.25v to be game stable. It needs 1.35v to reach 1250mhz and even then it artifacts.

So it seems stuck for now at 1220 / 7900

What do you guys think? My titan reaches 1180mhz with stock volts.
I would have thought the classifed would be able to reach more than this.

I bet most ref Ti's could reach higher clocks than mine?

It's stock lol. Why would I overclock for Bioshock Infinite of all games ?
I only OC for benching.

Yes that's correct RE mem

Sounds round about the same if not slightly better than my ref superclocked Ti's on air. On water with same volts I can get 1316 / 7950. Not good for a Classy mind you.

Yes they are all the same. At stock it ran pretty quiet (downclocks to 350mhz core) so would be fine for film etc. Overclocked in games or benchmarks you can hear it, but not over the speakers. If you want it for films / music make a second underclocked profile with temp set low as the priority maybe?
