660 ti Crashing Games Constantly -_- - Page 2

post #11 of 16
In my sig rig I use a EVGA 660TI and I haven't had any problems with it, currently I think I'm using the second newest driver through Nvidia's GeForce Experience center (Not at home to check, though I know theres an update available for me). I have it overclocked by about 70 MHz through Precision X and My temps hover around 63C when running Kombuster on stock cooling.

I haven't played BF4 or Titanfall issues, but I play battlefield 3 at high settings in 1440p and get great performance.

NVIDIA GPUs are designed to operate reliably up to their maximum specified operating temperature. This maximum temperature varies by GPU, but is generally in the 105C range (refer to the nvidia.com product page for individual GPU specifications).

The 660 TI's max temp is 97C so I wouldn't worry about 70C, should be working fine, but I'm a proponent if cooler is always better so perhaps cleaning out your card or adjusting fans if you want a lower temp. If you are getting accurate temps you shouldn't have to worry about crashing at 70C.

Looking at your rig the only thing that I can think of for hardware problems is maybe your PSU is cutting it close since a 660TI stock has a 450W Minimum according to Nvidia. Your cpu and gpu are overclocked you might be cutting it close, certain drivers might affect power usage as well. If you calculated out the usage of everything 500W is probably sufficent, but maybe these games are causing a type of "perfect storm" with power usage? I always like to have a healthy safety net of extra watts if possible. Did your cpu and mobo decrease power consumption? It's probable since you went to Haswell, but you do have a pretty healthy overclock going.

Which Zotac Amp do you have? The 1033 MHz or the 1098 MHz? 1098 MHz is pretty high, at least from what I've been able to get with stable overclocks on my 660TI, EVGA's highest overclocked card is only 1046 MHZ in their FTW version. Looking at other manufacturer's 660 TIs I couldn't find anything approaching 1098 MHZ, most stop around 1050 MHz, maybe Zotac wanted to say they had the highest clocked 660TI? Could be a power issue with the massive overclock or maybe Zotac took it too extreme.

He wrote he reduced the clocks for the memory and that made it run stable. He did not say anything about the core speed. It's probably a bit beside the point to talk about power use and how good the cooling is or isn't if it's the memory speed that's causing the instability.

So many replies, you guys rock.

First: NOOB alert. I lowered the core clock by -25mhz and that's what seems to have solved it, NOT the memory clock. Edited the earlier post.

I will run with this for a couple weeks on every game I have and if it seems fine I will apply the downclock with Kepler, thanks xplode-bg.

Thanks for explaining ti Sisaroth. I assumed the factory overclocking was the point of ti cards. Now I get it. I don't think dust is the issue as I cleaned the card pretty thoroughly when I installed the new mobo and cpu and the problems started very soon after that.

PurdueBoy, I have the 1033. I also wondered about the PSU but I had used a couple different calculators before the build and they all seemed okay if I wasn't doing SLI. If I start having problems again it might be worth checking out I suppose.

deepor, like I said, noob alert. It was the core clock.

To take advantage of the popularity of the Ti model they continued naming some of their cards Ti.
But that's all choices made by Nvidia.

The factory overclock is done by Zotac and they apparently haven't done it correctly or your card has collected too much dust so the cooling isn't sufficient anymore.

Um, Ti has been around since the Geforce 3.


Op I would definitely look into a bios update for your motherboard. Not that it has anything to do with it, but Z87 isn't very old and there were plenty of stability fixes, especially for overclocking. Another thing would be to take apart your cooler and clean it out, and perhaps reapply thermal paste.

Haven't done anything yet as I still haven't experienced a crash since reducing the core clock and I kind of don't want to mess with anything. lol
Also wanted to mention that I installed a Hyper 212 EVO last week and while doing so realized that I had my 2 4GB RAM dimms in slots 1 and 2 instead of 1 and 3. Not sure how I managed that but I doubt it was contributing to my problems too much. I suppose I could raise the core clock again and see, maybe the ram not being in dual channel was part of it. *shrug*

As far as updating the BIOS is concerned, is that something I should do now even though I have everything running smoothly (it seems)?

Thanks.

If everything runs great, people usually recommend to not touch the BIOS. Flashing it can fail and you might end up with a corrupted BIOS, would have to battle with the BIOS recovery method your board has, so without a problem to fix there's no upside to doing it. I bet flashing can also fail so badly that the recovery method does not work anymore, so there's an actually scary risk to it.

I personally often still did it. You might want to see if there's an explanation of what changes there are in the newer BIOS versions. If it sounds boring, don't think about it. tongue.gif
