GTX 560 Ti Help!

That doesn't sound like a bottleneck issue. Do you use monitoring software like EVGA Precision or MSI Afterburner? If not you should download one and monitor your FPS, GPU usage, memory usage, etc. While it may not give you a simple answer, or any answer at all, it is generally a nice tool to have.

What games do you play? What are the other system components? Did you buy the GPU new or used?

Yea use one of the programs described in the above post to monitor your temps, there is a possibility its overheating and throttling itself back.

this isn't bottle necking issue, something happened there....

what are your PSU ?....

edit: 560 Ti quite power hungry about 260 W by it self

Total cobblers, they are 170w for the 384 core version and 210w for the 448 core version.

weks, looks like i got it wrong,,,,,,,

Anyway thanks for the correction mousemonkey....  

NP, please be aware that spreading misinformation is a violation of the T.o.S so in future check your information before making such statements. We can all make mistakes but some info is just too easy to find and therefore less easy to forgive when gotten wrong.

I bought the GPU new, off of Newegg. I have had MSI Afterburner for a while, but never really payed attention to it. I play games like Minecraft, ArmA II (DayZ), BF3 and some of the Call of Duty games. P.S. Thanks for the fast reply!

Well, this whole issue looks like it might be my PSU, considering that it is only a 420w. Any suggestions on what I should get? (cheapish would be nice if possible)

Why would it be your PSU?

It may be, but I doubt it. What is your current power supply units and the rest of your computer specs?

I'm not amazing with computers, but I've heard on other forums and youtube comments and such that I might need a better (or more watt) power supply to run the GTX 560 Ti well, because apparently it is a watt-hog. My power supply is only 420 watts, when I've heard people say you might need 550 or even 600. Since I can't think of anything else as a problem, and people say its not bottlenecking, I'm just guessing that it is the power supply. My full computer specs are below.

What is the make and model of your power supply unit? Which exact GTX 560 Ti is it?

Minimum system power requirement = 500 watts according to Nvidia. Not all PSUs are the created equal, so it is quite possible you are getting less than 420 watts. While the card draws about 170w, if you overclocked it it will require even more. Also some games are more demanding than others so throw that into the mix too.

With that said, it does not seem like the PSU is the culprit but I am relatively new to the PC scene so I may very well be missing something here.

Thanks for the help man. I think I just might go ahead and upgrade my power supply just to see how it goes. Plus I plan on getting a new processor and such too, so I might have needed to upgrade it sooner or later anyway. Thanks again for all the feedback.

EDIT: I've also noticed, while having MSI Afterburner up, that while playing games the GPU usage is around 25 or lower when the GPU runs well, but when it starts to lag, I notice that the GPU usage goes up to 99. Could this mean bottlenecking? The GPU is working too hard?

OOT : yeah it's my mistake for not double checking my source, I'm sorry for that (i'm read some reviews site and forget to double check with nvi web)

back to topic: PC sudently dies most common indicate power problems, so my suspicion towards the PSU...

If u can try to borrow some PSU from your friends... and meanwhile when u are changing the PSU try to reseat the GPU....

No still think its a heat a heat issue, Did you catch your temps?

Bottlenecks don't just occur after 3 hours, they would be happening all the time!

What about core clock speed when it starts lagging?

It's the driver i have 560ti my self and i had this problem..
Download this one..
http://us.download.nvidia.com/Windows/301.42/301.42-des...

Well it just gets very bad after a few hours or more. I only play Minecraft with around 60 frames, which I believe this card could do way better. I got the same frames with my old GT 430. I was definitely hoping for much much more frames when I got this card, and I'm very disappointed that it doesn't work as well as I thought it would. I see people with this card record with 120 fps. And that is kind of what I was hoping for. I probably should've said that I didn't get amazing frames even when it didn't die down.

I have already downloaded this driver, thanks though.

Didn't catch it. I'll try to check next time it happens.

Okay, report back when you've got the info!

I haven't got the core clock speed when it lags yet, (and I will as soon as it happens) I never really mentioned, but Minecraft, which is one of the main games I play which is why I mention it specifically, on max graphics, only runs at around 50-60 fps. That cannot be right. I know a few people are in denial about bottlenecking, and I've said it plenty of times, but if Minecraft runs 50-60 fps on a GTX 560 Ti, that's ridiculous. I say this because my old graphics card, a PNY Geforce GT 430, could run it with about the same frames. 50-60 isn't great for me either, considering that it is a bit choppy when I play. Might I have to upgrade the wrest of my computer's specs to run games well? Or should I be fine with the processor I have now? (AMD Athlon II X2 220)

Did you check GPU and CPU usage in minecraft? Does it run on 60 fps in empty world? Is Vertical Sync enabled?

Vertical sync is not enabled. I just found that the CPU usage for Minecraft is about 70-100% and the GPU usage only went up to about 40-50%. (This test was on an empty world)

Check task manager processes tab to find out what's eating the CPU!

You really must check the core speed and memory speed of your gtx560ti when you have those low frames.
My gtx560ti can behave the same as yours, and when that happens the core speed is locked at 400mhz. The only thing that i can do then is restart my pc and the problem is gone.
Looks to me like a bug in the power-saving feature of the 560ti.

Neither of my 560Ti's do that, I think you both need to double check your settings.

http://tinyurl.com/8v82sxc Here is a link to a screencap of the resource monitor while running Minecraft. Which, if you didn't know, is javaw. As you can see Minecraft takes up most of the processing power. As soon as you said try to find whats eating your CPU, I thought right away, maybe GameBooster will help because that is the purpose of that program (close all background processes you don't need while gaming). So I tried it out, and nothing happened. Still pretty low frames. I need to keep Skype open, which is another one of the CPU eaters, because I'm pretty much talking to friends all day. I think for me that just buying a new processor when I get the chance might be necessary. What do you think?

It doesn't add up. 40% from minecraft, and where is the rest of 30%? Do any of the services eat the CPU?

If you didn't see on the picture, it shows at the bottom of it that the services tab only takes up about 2%. So the services don't take up much space.

You sorted the list by Status. Something else must be eating the CPU. Could you sort it by CPU usage and then upload the screenshot again?

Sorry about that, here is the same list with Minecraft running with it sorted by CPU. http://tinyurl.com/8s7p7c2

Turn off gamestop app. It eats up the CPU. It should help reduce the lag. Also, why do you have C# compiler running? That uses a lot of CPU as well (not necessarily on that picture, but that's how it works).

After deleting a lot of the processes, I tried another test and opened Minecraft to see the CPU usage. The most space took up on anything other than Minecraft was about 2%. I still had bad FPS and the CPU usage was still around 80-100%  

That means you should get an aftermarket cooler and overclock the CPU...

I was planning on doing that, but I'm not sure if my motherboard even has the overclocking feature, its a pretty cheap motherboard I believe. It is the BIOSTAR N6853+
