Hi everyone, Im new to this forum and i just want to shoot out a question. I just overclocked my two gtx Titan in sli using evga precision x today. I'm very new at this overclocking stuff; so I just need some advice plz. Well these are the settings I used to get the highest possible score so far on 3dmark 11 (running 2560x1440 res with all test settings max out)

Power: 106%
Temp: 80C
GPU clock: +105 [if i increase..artifacts start to show]
Mem clock: +145 [if I increase..artifacts start to show]
Fan speed: 70%
Voltage: 1.3 mV

I'm gettin max at 1130mhz wit a lot throttling down to like 1000ish mhz when I hit 75C and above (sometimes). I'm just looking for a stable and relatively safe 24/7 OC and getting the highest possible OC of course. Am I on the right track? Is this the best settings for my GPUs? Because I see a lot of ppl can push their GPU/memory clocks to 140/200mhz and still be very stable! Any help?

PS: Im not really benching. Just want a stable OC. Im gaming at 1440p@ 120hz on those Korean monitors so I need higher OC to get stable fps 100+. When gaming; my primary GPU fluctuates from 967-1000 around 79C. My second GPU stays constantly at 1110 (79C)..with a little minor throttling every now and then.

How do I get my first GPU to be as stable? Is it because the card itself is actually slower?

These are my GPUZ specs:

GPU Clock: 942Mhz
Memory: 1575Mhz
Boost: 981Mhz

Default clock: 837Mhz
Memory: 1502Mhz
Boost: 876Mhz

I'll also echo that subjectively, MSI afterburner seems to be better for stable overclocks. You can grab the latest 3.0x beta from guru3d.

Another thing to keep in mind is that you may be able to offset the throttling with higher manual fan - although you will need the latest beta driver 314.21 in order to do so. The 314.09 and 314.14 had a bug which caused some configurations to throttle/downclock cards with fan speeds beyond 67% - but this has been resolved in the latest 314.21 beta (I've tested this myself - I had the same issue with manual fan!). So in summary, you're on the right track - be sure to stress test with something like crysis 3 or Unigene Valley. Also while GPU boost 2.0 is still a mystery in terms of throttle mechanism, you may be able to prevent throttle with manual fan and better temps.....be sure to pick up 314.21.

As the cards ship they will generally top out around where you are getting after they throttle. If you don't want to modify the BIOS, the best bet is to stick with what you've done. Find your max stable offsets and just play, not worrying about the throttling.

If you want them to give constant peak performance you'll need to use a custom BIOS, which generally gets you up to around 1150-1220 without throttling.

Ok ill try downloading MSI afterburner and the latest beta driver. Ill try to push my GPU clock with this and see if it helps.

Also changing the custom bios. Is there somewhere where I can learn how to do that for my titans?. It seems that you know how to get constant peak performance around that range without throttling. Any advice? By looking at your specs: I see your titans are running at 1170/7000 constantly I suppose?. Ill be happy if I can even get up to 1100 constantly. :)

I would read this thread at OCN thoroughly.

http://www.overclock.net/t/1363440/nvidia-geforce-gtx-titan-owners-club/3670

The first post you'll see at that link contains a download link for the BIOS that eliminates throttling. Read from that point on through the thread and decide if you want to use it or not.
