Let me say this again. See this post

This is from Ryan Smith (GPU Editor @ Anandtech)..

NVIDIA doesn’t believe voltages over 1.1625v on Titan will meet their longevity standards, so using them is still very much going to reduce the lifespan of a Titan card.

There are people who say overvoltage is fine, GPU degradation doesn't really affect until at least 3~5 generation changes (read 3~5 years of use) etc.... But.. IMHO, they don't know what they're talking about. They're in no way designer nor engineers of GPU let alone in semiconductor industry. Think about no. transistor counts packed into a single die. This is no crappy x86 CPU from Intel/AMD nor anything you've seen before. This is one of the most complex, sophisticated silicon you ever witnessed. (Intel's current flagship consumer CPU 3960X/3970X look like a ten year old technology compared to what is achieved in GK110).

For 24/7, I'd advice to stick with 1.150 ~1.162V. This is what Nvidia considers as stock core voltage for GK110.

Personally, I always overvolt my GPUs because I've never used any GPU more than 1 year. I upgrade often. So, I don't really care about the degradation. (I just feel sorry for those guys who buy my stuff. It's one of my reasons I never buy second-hand components. tongue.gif)

Fully tested in every possible game.

That brings me to my question:

I'm now running my Titan at 1110mhz/6200mhz with stock voltage and fully stable with my own modified bios.
The original Titan bios will only unlock voltage to 1.2v
Is it really safe to run 1.212v 24/7, or is it better to stick with maximum 1.2v set by Nvidia?

PS: I get a good performance increase from going 1110@1.6v to 1176@1.21v and only 1C higher temps.

That kind of voltage and increased power limit for 24/7 3D usage is fine as long as you cool your card properly. Simply isn't high enough to degrade or damage anything during the usual life span of the card 1-3 years.

Nice.

Keen to see what your loop ends up looking like. Any reason for taking the PCIe brackets off though?

Well I had them off while they were air cooled for more airflow so I decided not to put them back on. The stability from the bridge is more than enough. Also I noticed that on my V3 like yours, the bracket sits too low so they would have been of no use. I think they look better this way anyways.

I do understand about degradation and everything, and I have to agree with you. I know that I will not have a single problem doing some overclock/overvolt in this magnificent piece of hardware. The problem is not running my GPU with overvolt. Is running the GPU with overvolt that is NOT available in stock bios.
Since I do not know what they actually change in BIOS, i am more interested to know if this voltage is forced or just hidden in stock bios.

Thanks for the link and all the info!

Shame they are both like that.

I'm going to space my motherboard a little higher to see if it fixes it, if not I might just take it off also and suspend it with the tubing. Looks good without the brackets on.

Hi all.

A question if any1 can help.

My computer:

Asus maximus v formola
i5 3570k @ 4.6
titan evga stock bios @ 1149 turbo, can do more than 1176 with engineering bios,but need more cooling due to fan limit 76%
16bg corsair cl7 1600mhz
Corsair Ax1200
ssd and so on
Case for the computer is Haf 932

i use H100i and stock titan cooler today and i am looking at water cooling , cause i want lower temp on my gpu and maby wanna try push it abit more.

Will this Kit : http://www.coolerkit.se/shop/xspc-raystorm-d5-2992p.html

Be ok as a start to cool my cpu and gpu , will add sli in the future i think.
or do i need more radiator area for cooling sli titan and i5 3570k?

And my temp in prime95 stays about 66-70 c , how low is expected to get on a cpu with a "normal" watercooling system?

ive read that 120mm radiator is needed / 100 watt heat , but not realy sure if thats correct and how much 2; titan and 1; 3570k will need to keep at desent temp.

Best reguards Rickard

Test fit done, now to wait on my Koolance QD3's. I'm gonna try them and the swiftech qdc's when they come in. Im gonna place them at the back attached to the bulkheads so I can remove the everything on the top tray when I switch hardware (XL-ATX Msi Xpower when it releases). Still need to find a good draining solution though, this got pretty messy.

I've always rolled my eyes at people talking about vram and skyrim mods. now I find myself going back and playing with 20+ textures mods. game is stunning and eating up 4+gb of vram. love my titan.

What's the deal with skyrim. I've never played it. Is it an online game where other people can kill you or offline play against the computer? Does it end? What's the objective?
