780 ti overclocking issue.

[azulon]

I have a gtx 780 ti with an asic quality of 78.6 percent. Zotac, with stock reference cooler.

I have a 1200 watt power supply.

So I know I am able to get 210+ on the core. so it boosts its way up to around 1232 mhz almost most of the time. But the memory, I go to even 300+ boom green artifacting squares on the screen. pull it down to 250, green artifacting. i am currently running at 200+ on the memory and 210+ on the core.

Shouldn't the 780 ti memory be easy to overclock. people are saying that a thermal pad might not be perfectly attached to one or two of the memory chips? is this the truth? should i return.


Anyone know anything about the 6gb 780 ti rumour?

 

[Devballs]

That is a decent over clock, and all in all it boils down to the chip lottery.

I doubt they will release a 6gb ti. They will probably release the maxwell version of the titan that will have 6 gigs. They wouldnt want to undercut the sales of their newest card just released until AMD gives them a push.

 

[mr91]

Your ASIC quality is good, My reference asus card has an asic quality of 73.4

I wouldn't touch the Memory because with such a high overclock on the core you're probably going beyond 106 % on the power consumption if you're using 1440p...

SK Hynix is the memory that the 780 ti uses at 7 ghz @ 1.6 v, I heard many people are having problems when overclocking this memory.
The memory works great at 7ghz.

What fan speed are you using for your overclock?
Are you using 1080p or 1440p

My max stable overclock is + 150 on the core

I heard the 6 gb version is coming however nothing official yet... Maybe the 6 gb version will be using samsung which apparently is a better overclocker.

ok so what i am wondering is man. this core clock stability. How exactly do you know. i mean for sure. like what is the procedure. because i have done unigine furmark for one hour at 250+ core and 300+ memory, ran without a hiccup. But i trying playing metro last light, green artifacting and freezing after 25 minutes or so. What is the exact procedure? plus, you think that the problem for my memory is that basically power limiting factor? Because at 1440p, i almost typically am over the 106 percent, usually goes to 104-111 power usage.

on another note there is those custom bios i have tried which allow you to increase power limit to 200 percent. but would that make a difference, is the actual power delivery on the card only able to supply X amount of watts. if not, how can i get rid of this pesky annoying little power limiting nonsense, Because i don't care if my fan is at 100 percent all day long, noise does not bother me.

Thank you.

Some people overclock their GPU's for bragging rights however I personally overclock because i want a better gaming experience...
The problem with overclocking too much is it makes the card less stable and sometimes reduces the gaming experience...

Personally I wouldn't touch the memory on my 780 ti because you won't gain much performance unless you overclock to 8 ghz however that is not realistic for most people.

I suggest try to find a max overclock for the core and because of load balancing, Nvidia says this card is the best card to get a stable overclock with.

Based on my previous research the PCI express has a 75 watts, the 8 pin 150 watts a and the 6 pin 75 watts for a total of 300 watts.
This would allow the card to run at 117% of the power limit approximately.

In theory 117% would allow you to get more performance out of your card because if you're getting more than 106% usage that can indicate a stability problem.

I find that Metro is stable with overclocking the core only however games like tomb raider with tress fx and new games that are not stable yet like Call of duty ghost and arkham origins effect stability when the gpu is overclocked. In my opinion you need to calibrate your system every time you change games unfortunately.

When you turn your fan to 100% it uses more power so a 117% power limit should help you with your fan profile and overclock. Cards like the 780 ti classified offer a 375 watt max with two 8 pins for more extreme overclocking.
However unless you're using a high end water cooling solution with increased voltage or liquid nitrogen on a kingpin card
extreme overclocks are usually not possible on air.

I upgraded from a gtx 780 to a 780 ti and the gtx 780 had samsung memory so I was able to overclock the memory to 7 ghz no problem however i also increased the voltage because the when overclocking memory, voltage is sometimes helpful but increased voltage uses more power.

I'm glad i upgraded to the 780 ti it's much better than the 780 for 1440p gaming - I find that even at stock the 780 ti plays Meto last light quite well
@ 1440p maxed out as long as ssaa is disabled - what do you think?

What bios did you get?

OH Yeah, man it totally plays it well and stuff, so my question is, basically a card with 2 8 pins is much better? And i have to recalibrate for each game, holy hell, that don't even seem like it worth the time to be honest lol. also question. what clock settings did you get on your gtx 780 ti? and what model do you have in particular. Cause i don't know, i was hoping that this card, being expensive as hell and all would offer me some overclocking headroom. i have heard and read that memory overclocking to 7.5 ghz was like a given for these cards?


Also I was using the sky3nt Zotac 780 ti bios.

 

[mr91]

I have a Asus gtx 780 ti and the highest overclock I could get is an extra 150 without overclocking my memory and even with this modest overclock my power usage would sometimes go up to 111% and my maximum clock would be around 1150 with my fan running 70%.

An extra 250 on the core is spectacular especially with with the gtx 780 ti because you have 2880 cuda cores.
The general rule is the more stream processing cores the more benefit you get from overclocking.

The two 8 pin connectors will give you more overclock headroom, the Classified also has dual bios and is designed for overclocking.
The Classified cards are cherry picked and they will usually have higher ASIC scores.... Based on my experience with EVGA, Gigabyte and Asus over the years I find that Asus makes the best product...

Kingpin overclocked his card to 1.9 ghz and his memory to 7.8 however the kingpin card has 2 X 8 pins and a 6 pin for a total of 450 watts and he used Liquid nitrogen and more voltage... When it comes down to overclocking you got a good card because of the high ASIC quality and your card goes over 1200 MHz. I heard of people getting 60% ASIC quality on their 780 ti super clocked cards because EVGA reserves the High ASIC cards for there higher end cards...

you need to head over the the overclock.net official 780ti owners thread. your card probably uses the cheap hynix memory and not the samsung memory. there is a third one used but i forget its make. if you want a good overclock your going to need a skynet custom bios and some voltage and llc conditioning. the custom bios allows you to hit a much higher power target. head over to overclock.net.. nothing against toms here but…. overclocking the 780/ti is over most of toms forums heads.

 

[mr91]

Most if not all gtx 780 ti's use sk hynix memory this can be checked with Gpu z -

The third one is Elpida and that's only used for the 780 not the 780 ti - Elpida was acquired by micron and I don't think they produce 7ghz memory last time i checked.

The OP has tried a custom bios, I don't think overclock.net is necessary better than toms hardware for overclocking it depends who is participating.

Sites like overclock.net usually focus on high scores on synthetic benchmarks rather than real world stable performance gains in games.

sorry to bother you again man, but i am wondering is the asus direct cu II has 2 8 pins connectors but does it actually have the VRM design to handle that power, cause now i am reading the reference nvidia design have 6+2 power phase design, and that only 6 power phases cannot handle more than 300 watts anyways. i am confused as heck

Also would an asus card be worth it. Because the zotac gtx 780 ti cost me 610 bucks on sale on newegg.com. it came with the games which i am selling for 40-ish bucks. i mean it was a good deal, the asus direct cu II is like 710 bucks now. surely it isn't worth the 100 bucks right? i mean overclocking is badass, but 100 bucks worth it?


also lol you seem smart about this stuff, mind telling me your steam id, in case i ever need an emergency helper.

thanks.

Hey man, i have tried the skynet bios, its working and all, but I don't want GPU boost disabled, actually I think it was one of the main reasons i bought this card to be kinda honest with you. I love the idea and concept of the control of a gpu like that. Skynet disables that. I don't need voltage modding either, actually. 75+ is enabled already and its perfect. What my problem is that my card continually hits 1270 but has to back down to 1230-1240 because of the pesky power limit. I want everything about the bios to remain the same, EXCEPT for the power limit, i just want a bump on the power limit to 120 percent is there anything like that?

The Reference design as I mentioned earlier can only handle 300 watts max in theory because the 8 pin connector provides 150 watts of power, the 6 pin 75 watts of power and the pci express slot provides 75 for a total of 300 watts. In the past before load balancing the GPU couldn't distribute the power properly and sometimes this would cause the gpu to fail however there were non reference cards with custom PCB's like the Asus that had arguably a better design for overclocking.


I wouldn't think too much about the power phase design that has to do with power distribution & voltage regulation. Basically the better design will improve efficiency and stability for overclocking and general operation and longevity.

The power phase for the reference card is 6 for the gpu core and 2 for the memory and for a card designed for overclocking like the classified kingpin edition has 14 power phases for the gpu and 3 for the memory... The kingpin can also use a 450 watt maximum.

The new Asus direct cu 2 has 2 x 8 power connector for a potential of 375 watts, below are some more details about the card.
I think you got a good card and got lucky to get a card with a 78.6 Asic quality, I'm don't think you should spend an extra $100 if your card is working properly because even a stock gtx 780 ti will give you a great gaming experience at 1440p while playing a demanding game like Metro LL.

The benefit of the Asus card is you might have a little bit more fun overclocking it however I suggest you keep this card play with it and until the next worthy upgrade and try a high end non reference card however when you get a non reference card you have to take into consideration that they are not a blower style card like the reference and you need to put them in the a good case with a proper fan configuration or hot air will circulate in your case...





Basically if you want to get the best overclock, I recommend you get a ROG Motherboard that has an excellent power design with the very high end Japanese capacitors and chokes, the best power supply like a corsair AX 1200 i Platinum or a platinum Seasonic that will have High end caps and a digital power design, Make sure you get a good case with a good fan arrangement and water cooling if you want to be more extreme.

You will also need compatible stable ram and components for your system and a high end non reference card. You can then practice more extreme overclocking.

If you read the specs you will notice that the card uses a 10 phase power design, digital voltage regulators, Japanese capacitors, probably high end chokes and other components that are part of the power design/ voltage regulation that improves efficiency and stability.


I think Asus will eventually introduce a ROG version of the 780 ti that will be even better!

DIGI+ VRM with Super Alloy Power

30% less power noise and 2.5X greater durability
Acclaimed DIGI+ VRM has been applied via a 10-phase power design that uses digital voltage regulators to minimize power noise by 30%, enhance power efficiency by 15%, widen voltage modulation tolerance, and improve overall stability and longevity by 2.5 times over reference.

POSCAPs to lower power noise, enhance overclocking, and improve stability far beyond standard analog designs

thanks for being so patient, you going to get a 6 gigabyte 780 ti if it comes out, i bought this 780 ti and will have to give it to him when he come to america. when i give 780 ti to him in 1 month-ish to him, i will be going back to my radeon hd 5870, great card for sure and all. You think 6 gig 780 ti or maxwell? Because i am not sure if maxwell will be during may or not. I am hearing its going to be 20nm and then i hear its 28nm. 20 nm means late q2 or early q3, might not wait gahhh. or i might buy one of them evga cards with step up lol. so seriously whats your thoughts? is maxwell 20nm or 28nm, because both AMD and Nvidia have come out saying the benefits of going to a lower process node are diminishing, especially in terms of cost.

but i am thinking, isn't the gk110 the limints of any 28nm chip, i mean 7.1 billion transistors, and 561 mm die, and the 780 ti power consumption IS NOT PRETTY AS IT IS. so what the heck else can they do with 28nm? surely maxwell is 20nm right? let me know your thoughts man.

You're welcome - I'm not going to get the 6 gb version of the 780 ti because I don't have a 4k monitor and I don't plan on getting another one for SLI.

I don't think the flagship Maxwell will come out until the 3rd or 4 quarter of 2014 because of the complex architecture and die shrink to 20nm.

I heard rumors of a gtx 790 and a competing AMD dual gpu Hawaii solution is on the horizon...

I also heard rumors that the 20nm AMD flagships will arrive in the first quarter of 2015.

The gtx 780 ti might be the king of GPU's for a while and it will be difficult to get much more performance out of a 28 nm Kepler because the gtx 780 ti is fully unlocked gk 110...

holy balls, no way dude, a gtx 790? two fully unlocked gk110 cores lets say, with maybe 6 gigs of ram. HOW THE HECK DOES NVIDIA cool that thing, the 780ti already consumes a retarded amount of power at full load. i mean surely it cannot be done right? RIGHT?

Does anybody know a safe temperature to run the 780 ti for a long long time. I mean my gtx 780 ti goes to 86 degrees and stays there under full load. Is it going to hugely reduce the lifespan of the gpu if you put the extra ALLOWED 75 mv?

Zotac reference cooler, fan is set on auto software control. 106+ power target, 75+ mv. 1232 Mhz core clock, 1850 Memory clock. 95 degrees temperature limit.

Is this alright? i mean these cards are well engineered for these stresses right for the most part?

 

[mr91]

The Temperature should be okay however with that overclock and voltage increase the card probably won't last as long but you have a 3 year warranty you can use... The gtx 780 ti was Designed to be overclocked - Is your card Throttling with that overclock?

I read a lot of stuff about people damaging their memory when overclocking it...

no throttling man, always runs fine with the clocks, its being throttled by the power limit however, but not real throttling for temperature. what do you mean my card won't last as long? it will last long than 3 years right lol? i expect it to haha, i mean its umm kinda expensive.
