The GTX Titan X owners thread.

I've found out that the high temperatures I'm seeing on my Titan X are due to having three monitors attached. Unplug one and the temps drop significantly.

I've been giving serious thought to a second TX and I'm wondering if having two monitors attached to one card and one monitor attached to the other would work and be cool? I'd be gaming on the single 4K monitor with the cards in SLI.

So its all up and running and I have to say its brilliant. The buzz from the rad was pretty loud last night but after 8 hours of gaming I can barely here it. Managed to get 1480mhz stable with a 0.72 voltage bump and the temps dont go above 55 degrees! This thing is amazing and my only complaint is that for £100 they should throw a decent fan on that thing or at least a silent one. Im going to stick two sp120s on there and that should take care of it though.

So basically,if you can get hold of one of these things...do it!

Really nice OC and the temps are great. Considered getting some AIO's but i don't think i could fit all the hosing etc in. Plus i do love the geforce led logo, i wish that could have been somehow left alone.

In this heat i am running the top gpu at 90% fan speed to keep it at between 80-85 degrees on the witcher 3 at 4k, bottom one at 70% and the middle one not being used for the game (as 3 way sli is not properly supported on this game) at 60% fan anyway. I can cope with the noise as it's not next to me but it's obviously not silent like the AIO.
 
Got my second TX in today. However I seem to be getting worse performance than with just one card. I have tested each card individually and they are both working correctly. I have un installed the drivers and re installed.

I am wondering whether my motherboard / CPU might be causing a bottleneck? I have an Asus P8P67 Pro which is supposed to support x8 / x8 sli however GPU-Z is showing the second card to be at x4. I can't find any settings in the BIOS to change this. The CPU is a 2600K @ 4.8.

I have not used SLI before, does it matter which connectors you attach the bridge to? I have EK waterblocks and this prevents me from using the second set of connectors.

Another annoying thing is that if V-Sync is enabled then games are locked at 40fps.
 
You can use either set of connectors on the gpu as long as they are both connected on either the left or right.

This is a pic of your MB with the PCI E slots marked, which of these are your cards plugged in?

What v-sync are you using? Have you got the v-sync in the Nvidia control panel set to v-sync smooth (this is an sli v-sync and would lower fps in certain circumstances.

Are you using the latest gpu-z to ensure it's reading stuff correctly?
 
I have a feeling that your setup are not going to allow your gpu's to run at pci-e 3.0 where even x4 would be okay in a pinch. Pci-e 2.0 on the other hand unless that runs at x16 is where the issue might be. Pci-e 2.0 x4 is a no go. Gpu-z should tell you at the bus interface bit. Mine for example says "PCI-E 3.0x16 @ 16"

EDIT: just did a check and pci-e 2.0 at x8 x8 should on todays gpu's normally be ok compared to pci-e x16 x16. Not sure if the titan x would test that result though.

Specifically what games are you having issues with? I found Witcher 3 was better with SLI disabled.

I tried witcher 3 and the performance was so bad I closed it down (15fps). I have been mainly playing GTA5. With the settings I was using I was getting between 45-60fps but mainly around 56fps. With second card I am now struggling to get above 51fps.

I have been using in game V-Sync, did try they Nvidia control panel version also with same issue. Have not used smooth vsync yet.

I am using the top and middle PCIe slots (not the black one). Using latest version of GPU-Z.

Seems like sli should work properly when in the top slot and the next pci-e slotx16 that's white. If you use the bottom black slot you will run into many issues.

Interestingly I have just tried each card individually in the top slot on their own and I am only getting x8.

I am waiting on a delivery for the second waterblock from another supplier due to OCUK being out of stock. Currently I am running one card with custom water and the other has stock cooler, could this be causing an issue? One card is running at 86 degrees whilst the other is only around 45 degrees.

I think you may be right. I was hoping to wait for Skylake E before upgrading motherboard and cpu but looks like I might be ordering an X99, DDR4 & 5960K :(

FWFW both Witcher 3 and GTA 5 run amazingly, (and by that I mean much better than single GPU config) in Windows 10 with SLI enabled. Not sure what OS you are using but the imminent release of Win 10 might help.

Yeah me too. Son as I saw the "PCI-e x4" part it set alarm bells off

Witcher 3 in SLI runs weird for my in Windows 10 tech preview - 352.84 WHQL driver

GTA V runs fine though.

Sort the PCI-E lanes out though as others have said.
 
Assuming you are using the correct blue and white slots try going into the bios to here.

The AI overclock tuner needs to be set to manual and then BCLK/PCIE to the max setting of 300.0 and see if that gets you x8 x8 speed. This setting may need you to set a new ram speed possibly. See this quote from a review.

EDIT: just seen your post about your slot usage, sorry

First try the white slot with 1 gpu and see if you can get x16 in that one, if that fails then try the bios settings i described and if all this fails then check if any of the pins are bent on the MB pci-e slots as this may be the cause also, are any of the pci-e slot locks broken or do they click closed ok when you install the card?
 
Thanks for all the help. Following Vegacortez's guides I have still not been able to get one card to run on x16. I have taken the second TX out for now and wait until I have made a decision whether to go X99 or not :)
