I've just bought a second Titan to pair it with the one I'd already had. I thought my first Titan was a dud because it only OC'ed by 100MHz on the core and 400MHz on the RAM. This one can't be OCed at all, what's more I notice some strange artifacts from time to time. Is there any program which objectively measures graphical glitches? I'm virtually sure the card is borked but I'd like to have something concrete. I remember a program for OC that had a preview window which counted glitches I'm looking for modern equivalent. It's the first time I bought a used card and the last. The card is under warranty, why the seller didn't first repair it and then sell it? Now I have to start the whole process which drives me crazy. Getting money back is going to be more hassle then simply RMAing it.

Have you tried the kombustor or whatever it is called from msi?

What are you seeing artifacts in? Have you tried the card on its own? Usually artefacts are down to the vram. Have you tried downclocking to test?

I found kombuster didn't cause artifacts at much higher clocks than the metro last light benchmark did.

Does it work properly at stock? Then it's not borked. You berk.

No, it doesn't, it artifacts at stock. As for Kombustor, it doesn't work in SLI.

Downclocking doesn't help. I'm seeing artifacts in every 3D load that utilizes both cards.

I'm going to do that, the application that shows the worst artifacts is Uniengine Valley.UPDATE:
It turns out that even my old card alone renders Uniengine Valley with artifacts. Strange. I don't know what to think about it. Most likely either both are borked or neither is borked.

Drop your CPU oc and put it to stock and test.

Doesn't Valley currently have issues with the current nVidia drivers? It's supposedly fixed in a recent beta/dev version that's floating around, but I'd suggest trying another program like Heaven or 3DMark.

EDIT:
[Redacted statement about 340.43 drivers] Nevermind, I didn't realize there are newer WHQL drivers out at the moment, but my statement still stands on artifacts in Valley. :)

EDIT2:
If you're determined to use Unigine Valley then you might try these 340.66 drivers from Guru3D which supposedly fix the artifacts. Use the modded inf from the same thread, but if you don't know how to do this then you might want to review this thread, as well.

MiRai thanks for helping me out. I'm not particularly interested in getting Valley to work properly it's not like I can play it. So most likely it's just a software problem and my card is fine, right? What's the best way to test if everything is OK with my second card?

As was mentioned, titan cards don't like to be OC'ed...
So, you are creating your own problem with trying to OC them.

I oced my new card on its own for maybe 5 minutes, everything is at stock now, except for the fan profile to keep them from throttling.

I'm getting artifacting as well in Valley 1.0. I describe it as white flashing patches whenever mountains show up. I have a GTX 780 Ti and nothing is overclocked. It started happening a few video drivers ago but I'm not going to go back to a very old video driver.

OP - try playing a game in SLI with stock frequencies and report back. Unigine is notorious for artifacts. It would artifact my Nvidia cards long before any games would.

Do you have Crysis 3? That will artifact fast on a bad card.

As a fallback, just run 3dMark Fire Strike at stock speeds in SLI. If no artifacts, your system is probably fine.

No I don't have C3. As for demanding games I have Metro LL and Wolfestein NWO (not so demanding). Fire strike seems OK visually if a bit too slow fps-wise. I will have some time tomorrow to play those games.

I think that is a driver problem, I didn't have that until I upgraded from a 670 to a 780, using newer drivers but apparently other 780 users have noticed the same thing for the last 2 drivers.

Good point, the grenade arc was all over the place in Crysis 3, I had to reduce the memory clock more than with metro last light to get it to behave properly.

I read many comments about the artifacts in the Unigine benchmarks in Guru3D forums. So far the Nvidia driver updates haven't fixed this issue, as far as I know.
If you are interested in overclocking Titan, you should refer to Overclock.net site ( http://www.overclock.net/t/1363440/official-nvidia-geforce-gtx-titan-owners-club). They developed a method to unlock GPU core voltage for Titan and gtx780 (but not Titan Black and gtx780Ti). Their unlock mods together with vBIOS to increase the power limit and with appropriate watercooling blocks have worked wonder for Titan.

Thanks, but my first Titan was already a dud and increasing Voltage didn't help much. I thought I couldn't get a worse Titan but I did, my second Titan can't be OCed at all. My first was good for +100/+400. Anyway at 65% fan speed they get very hot at stock in SLI so overclocking would result in a lot of noise even if the cards could handle it, so it's not much of a waste except for memory OC which practically don't increase temps at all. Still, it's a very fast set-up and with that amount of memory I don't think I'll ever run out of memory. I'm going to be looking for a third one for TRI-SLI but the price must be lower than what I paid for the second one. For 1/3 of the launch price I would buy 3rd card in an instant but right now they are about 1/2 the launch price and they very rarely show up in auction site in Poland. Unfortunately it's a very poor country and very few people bought a Titan in here so there's almost no supply of such ridiculously expensive used cards here.

UPDATE:

I tested with both cards installed with the recently bought card as the main card and this time it handled the frequencies that my old card could muster just fine. I tested it in MSI kombustor without SLI activated. It even passed 150/500 just fine but I'm not going to test how high it can go because I'm going to be held back by the card that clocks lower anyway. I'm going to test with both cards overclocked and SLI active.

Is this 3Dmark Fire Strike Score fine for dual Titans in SLI?

16328 with NVIDIA GeForce GTX Titan(2x) and Intel Core i7-2600K Processor
Graphics Score 22496
Physics Score 12037
Combined Score 6476


Can anyone with dual GK110 share their results? (2x780(TI)or2xTitan(Black))

I'm curious if 2x8lanes of PCI-E 2.0 is holding my cards back or not. I'm thinking about upgrading to 5820K but it would cost a lot because I would also need to change memory to DDR4.
