The GTX Titan X owners thread.

I thought it disables SLI if you run any monitors off the bottom card?! Used to be the case for definite.
I run 3 monitors on my previous 780ti SLI set up and have lovely low idle temps and SLI functionality by having 2 screens attached to the top card, and one to the dvi port on my motherboard. If you have a motherboard that has this option it's a great solution!

If you attach more than 2 screens to one card it can't enter low power state. Also if you have a high Hz monitor then If you run the desktop at over 120hz again the GPU can't enter low power state.

I have run SLI since the 680s and never had an issue with SLI and 3 screens. The top card clocked higher but I was on water, so didn't care. Same with the Titans. Water cool and never look back.

It's pretty cool, no pun intended, to see 2 cards on a 3 monitor set up idling along at 26 degrees on the desktop though. On air. I might look into water cooling for a new build I'm planing later on this year though. Never even seriously thought about it before but I think I will for this one.

The problem for these cards is the default fan profile is so damned rubbish and the 600Mhz clock (I think it is) warms up the card just enough to look bad. I noticed the same for 144Hz desktop and the top ard was getting rather too warm for just browsing, so knocked the desktop down to 120hz and everything is back to peachy.
 
Right

It turns out that, yes, you can run monitors off both cards, but only if SLI is disabled.

2 displays in the top and 1 in the bottom brings the idle temps to 29C

Technically I only have 2 displays anyway

AOC 2770PQU via DisplayPort (1440p @ 60hz)

&

Panasonic 58AX802B via HDMI 2.0 (2160p @ 60hz)


Unfortunately I use the DVI port for HDMI audio (using adapter) in to an A/V Receiver and that receiver passes through video to the Panasonic TV. So that is appearing as a 1080p display when really I only want the audio.

Problem with HDMI is that you can't just turn off the video portion of the signal.

Any one think of a way around this? Motherboard is X99 so no onboard HDMI output. It has onboard sound card but only analogue audio or compressed S/PDIF

I like Uncompressed PCM over HDMI because it supports high-end sound output like DTS HD

here are a few game benches from TitanX v GTX780 Classified.
cpu @ 4.6
780 @1176/6502, 1306/6502 and SLI 1176/6502
TitanX @ 1177/7012, 1277/7512 and 1424/8002

Games all at 2560x1440. Chart shows average frame rates.
Dirt Showdown ingame benchmark Ultra 8xMSAA
Grid AutoSport ingame benchmark Ultra 8xMSAA
Bioshock Infinite ingame benchmark Very High
Tomb Raider ingame benchmark Ultimate with normal hair
BF4 fraps, campaign Shanghai Ultra, 2xMSAA, no FXAA



single TitanX is basically as good as SLI 780 in these games:)

very impressive

thing is, the Titan X is a full GM200 so when it overclocks it reflects a lot more in performance..and the performance gain overclocking is amazing,
is this on water?
 
One thing I'm not a fan of with the Nvidia cards is the boot process.



On the AMD card I would get to see the whole boot sequence on all the monitors connected.

On the Titan X it seems to prioritise the DVI output (if connected)

Failing that it comes up on my TV (HDMI 2.0) but only at 640x480.

My Primary desktop monitor (DisplayPort) doesn't show anything until Windows boots up to the login screen.

Strange system. Presumably if I took the HDMI cable out and just left the DP cable in, it might show up then?

It just makes getting in to the BIOS a bit of a faff.

I'd rather they spend R&D £ on stuff that matters than getting that imrpoved :)

Is it possible to get in to the GPU BIOS and change the primary output or anything like that?

Or is there a running order for the outputs?

It has 1x DVI, 1x HDMI, 3x DisplayPort.

I used the DisplayPort to the far right of the card as you look at the rear I/O plate (next the the HDMI output). Does changing it round make any difference?

Yes,

The first initialised port is the one closest to the motherboard, so it would be the one to the left if you are looking at the back of the case.

This has been the case with the last 3 graphics cards I've had... 970, 980 and Titan X


DVI is usually initialised before displayport.

I'm not sure about the HDMI port.
 
Makes sense I suppose.

I'll switch the DP around and take the DVI out and that will hopefully solve it.

Anyway, enough about my quirks.


Sli Titan X
Far Cry 4 - 2160p - Ultra (No AA) + Nvidia Gameworks HBAO+, God-rays and Simulated Fur

Didn't drop below 60fps

I turned on TXAA x2 as well and it was averaging about 50 fps.

Super smooth as well, unlike when I played it on 295x2/290x.
