Try this:

  1. Shutdown pc remove the PSU power cable
  2. Remove both 8pin cable from GPU
  3. Press power button in the rig to discharge the PSU and the rest of power in the circuit board
  4. Wait about a minute ( two minutes recommended )
  5. Plug back the PSU power cable
  6. Do not plug back the twi 8pin power cable to GPU.
  7. Turn on PC boot into UEFI or Bios and enable IGPU ( GPU integrated in the CPU ) if you don't have extra GPU to put in the first slot exit and save
  8. Boot into windows and wait just a bit to drivers load
  9. Open GPU-Z you will see the GPU there but you cannot use it yet because it is only powered by PCI-E only
  10. Open nvflash and flash back to working bios or vBios and have fun

Hello!
You know what? My third titan has come back by itself. I have no idea of what happened but I'm happy for it smile.gif.
I then cud easily flash its bios smile.gif

LOW GPU UTILIZATION
While using 2 of them with cpu i7 3970x at 4.4ghz I get a gpu usage of 75%.
With 3 cards an usage of about 52%. I went up with cpu OC to 4.7 but I didn't notice emprovement.
So with a third titan the only thing that gets better is frametime. Yes the game is a bit smoother. But can't play smoothly with graphic settings over "very high", the extreme and the ultra setting cause fps drops.

Is there any way to optimize the utilization of those gpu's?
I remember triple sli of gtx680 with an usage of more than 80% of the cards resulting in even higher fps.

Im using drivers 322 (or 314.22) because with 4 newer driver the game was less smooth.

I'd like to play this at 144fps, for now I have fps from 60 to 110.
I haven't unlocked the voltage and clock over 1170mhz, but that won't rise the gpu utilization.

if the cards are only using say 50%, but you are getting perfect FPS - it isn't an issue

If the cards are only getting 50%, but the game is running like arse - most likely a CPU bottleneck.

if the cards are only running @ 50%, and CPU cores are only running @ 50% - most likely poorly optimized, as DX11 bottlenecks only occur in BF4 & Star Swarm benchmark, right now.

no the game runs smooth, cpu usage at yes 50-60%
Isn't there a way I don't know, playing around with sli profiles, to optimize it?
If you look at reviews they show crysis2 scales well with titan multiple SLI on crysis2, but the multiplayer is different than the single player....

Motherboard bios corrupted? Damaged PCIe slot?
Try another card in that particular slot, if another card gets missing or not recognized you know its not the card but the PCIe slot!

LoL now people going to bash the Z under air cooling just watch. Two TITAN under the hood on air cooling. Hope for a nice WB.

I'm sure the flame has begun somewhere on this forum (and others) already.

I has just shy of 1.5 titan Z, so tongue.gif and guess what? It cost less than 1 Titan Z!

Check the pci-e connections to the PSU. It might just be a somewhat loose connection on the third card.
post #22908 of 28136
Quick question .. if you had the choice between DP or DVI connection witch one would you use 2560x1440

or should I just ask witch is the better connection

Looking into this the Titan Z seems like a sham like Baasha said call it Titan M for Muppet edition. Why spend 3k when you can spend 2k for two titans.
