Question on 1-2 Titans in Surround 7680 x 1600 ( Crash / Do I need 2?)

post #1 of 9
Thread Starter 
Hey guys so I am in the same boat as nyxagamemno, I have 3 30" 2560 monitors and am using a Titan and 1 GTX 460 for PhysX (in my understanding the GTX 460 does not seem to be doing much)when I play games like TF2, everything is fine. However, I finally loaded up skyrim at max settings and the card crashed(had artifacts, and at Ultra high with AA/etc it went down to 20fps)I also had some questions about EVGA Precision and how I can maximize the card.

Which settings should I typically be checking to monitor the card? See the photo for what is listing currently


I I understand this right:
GPU Power tells me my Power Voltage target (here its 103% so how much of that I am using)
GPU Clock is my clock speed here its O/C to 993MHZ
GPU1 Temp here it is 56C
GPU1 Usage Here it says 99% that means I am using the card to 100% basically right?
GPU1 FB Usage Not sure what exactly this means but it says 49%
Mem1 - GPU Memory Clock What the memory is being run at, addly enough it says 3029 Mhz, I thought it ran at 6008Mhz
GPU 1 Memory Usage Here it says I am using 4mb out of 6mb

Frame Rate WoW 27.6FPS and I am not doing much with a Frametime of 38ms, Is that bad since 1 card should not have micro tear or is my frametime acceptable

EDIT: I had the settings set to 8 x 16 (Antaliasing is set to 8 and Anisotropic Filtering to 16). What settings should I be using with 3 2560 monitors? Reading the threads I may not even need these due to the resolution correct?
Changing it to 2 x 2 the frame rate goes up a little:


Look at the setup of my system here


Would love your thoughts

Its the first # 88%. Thats means you have more headroom to OC.

For most people 30fps is minimum, i prefer mine above 50fps though.

When you are looking for effective memory you double that of the Precision reading.

Yup, of you had a 780 you would be SOL.

For things to monitor with precision, I would take off Memory clock, FB, VID, and BUS usages. I don't think they are very important. Also, memory clock is basically reported as half of what it is. I don't have a reason to explain why, but someone else may.

Have you tried running Skyrim on stock clocks for the card? It may just be unstable (Not much of an OC, but no OC is guarantied). Also, for better results, you should prioritize Temp Target over Power so long you don't mind your card running hot. It should allow the card to clock itself higher if it has the room to stay within your Temp Target.

As I'm sure you realize, 1600p surround is an absolutely ridiculously massive resolution, so even powerful titans can struggle. Just turn down some settings so your framerate will be better. The difference between say Ultra and High is not very noticeable and can really help framerate. Lowering AA should help the most.

For overclocking help, you should be able to get help in the Titans Owner thread. http://www.overclock.net/t/1363440/nvidia-geforce-gtx-titan-owners-club/0_50

Yeah I am running skyrim mods, after updating and tweaking settings with no AA (set to 0), but everything set to high I am averaging 35-50 FPS mem usage of 2460MB (that means 4520 right?) with 90-95% usage.

Oddly I keep on getting 2 mouse pointers when I alt tab

Another odd thing is I set my GTX 460 to PhysX but in every PhysX benchmark its not utilizing the GTX 460 the Nvidia Overlay says "Physx>CPU" is that ok? Whats the point of having the 460 in then?
