Correct, around 1800Mhz. Forget the Heaven and Valley benchmarkls for gpu and mem stability. The specific Titan i own right now could run Heaven even at +700 mem with a little texture flickering and +600 perfectly clean. Still, the truth is that it's stable at +300 (probably at +320-330 but i didn't bother much to find the exact freq, at +350 Metro LL was showing texture flickering after 20 minutes or so).
My previous Titan was stable at exactly +240 mem.
My next, uuuuhm, give me some time and i get back to you...
Normally it starts at 1.137V (checked with my previous Titan), for some reason my current Titan starts from it's default which is 1.167V. I am RMAing it anyway but it's still mystery to me why it doesn't honor the bios voltage. TI bios allows you to use all the voltage steps from 1.137V to 1.1212V. Set it anywhere you like it.
Just talk to svl7 and ask him if he is willing to do it for you. Honestly if you need something like this there is no reason to use the TI bios, just use any other free-TDP with locked boost frequency and voltage.
Not in my experience. If you do use a stock bios though i would suggest to focus first on the maximum stable gpu frequency and then find the max mem freq (limited TDP). With a 350W i'd say no, again imho and in my experience.
+20C no way but yes it will run hotter since both the freq and voltage does NOT fluctuate all the time due to power throttling like with the stock bios. I run mine on air, stock heatsink, no it's not that dramatic but it will run hotter for sure (again it makes sense) but it's not anything you can't control by re-setting the fan curve to taste .
"Bottleneck" imho is kind of overrated generic word just like is "throttling" for the Titans. I am planning to do in the future a full review of 2600K/Titan scaling (about 20 or more benchmarks/games with both the 2600K and Titan in several frequencies ) which will tell the full story, so i'll get back to you.
In real world operation, single Titan, one monitor, 1080p i don't think it's an issue...just do a mild OC to your cpu and you will be fine.
You and me together mate...
I have already finished Metro LL with everything at max (physx on) and SSAAx2. Find a nice spot on the game and get screen captures with different AA settings (personally i have done it). I don't think we are missing much by not being able to set SSAAx4. The game imho has outstanding textures.
No worries mate, you won't get a throttle-free OC (or even stock operation) unless you use a high TDP modded bios (which ever you like and which ever does the job for you), that's the way Nvidia wants it and i am not a happy camper either.
In fact since i am RMAing again (unexplainable throttling this time at a very specific temp alhtough the temp target is set much higher and the temp limit sensor reports "0") the Titan i am surpsised about how sloppy Nvidia has become. Never owned an AMD/ATI card and i use pcs since the late 80ies. If Nvidia continues doing the same BS (GPU Boost 2 which doesn't even operate like it should and it varies from card to card etc) my next card (in a few years) will most certainly be an AMD.
Thanks for the info! Much appreciated. and I apologize for the delay in replying.
How can I achieve the optimum environment on my computer for benchmarking Valley 1.0? I've gone through the advised tweaks on the Valley thread, but I am wondering if there is anything more that I can do to improve my score. Any advice is most welcome.
If it helps, here's the current GPU settings that I use for benching Valley:
Driver : 320.18 (soon to be 320.39)
BIOS : Naennon's 145% BIOS
Core clock : 1202MHz boost
Memory Clock : 1877MHz in AB
Power limit : I try different values, sometimes a lower (120%) limit is more stable than a higher one
Voltage : 1.212v
Fan settings : Custom curve in AB, with 85% as max at a temp of 75c
CPU, RAM always remain at stock since my ambient temperature doesnt allow me to overclock my CPU and I havent attempted to overclock my RAM. Does it help the Valley score if I overclock RAM?
My best in Valley is 82.2FPS with a score of 3439. I havent been able to complete a single run at any more GPU clocks than the ones mentioned above, so overclocking GPU to better the score is probably not an option, unless there's a way to get higher stable clocks with the already maxed out voltage of 1.212v.
I know the other stuff wont give me much of a boost, but I'm wiling to learn and do (read tweak and optimize) anything if it gives me even a boost of 0.1 FPS. But hard-modding or such options that put my card/hardware at risk are out of the question.
Thanks a lot! I really appreciate the help!
