Hey guys,

I've got two PNY GTX 560 Ti OC2's in SLI running at the stock (900 Mhz) speeds and I think I may be getting some artifacts while playing Battlefield 3. I think what I'm getting is artifacts but I'm not completely sure. I've only noticed it with this game and have not seen them while running benchmarks like 3dMark11 or Crysis. It's definitely more annoying than the minor screen tears I get without using Vsync and they happen whether Vsync is one or off, whether I'm in motion or stationary, and regardless of what graphical quality settings I'm using. My temps for the cards never reach above 61 degrees Celsius. Also, I'm using the latest official, non-beta driver for Battlefield 3 and Rage: 285.62. I have not had this issue when using previous drivers for the game or when I played the BF 3 beta on only one of the cards. Do you think one or both of my cards are duds? Do you think it's a driver issue? Thoughts?

Also, I while try and get a screen shot or two of the problem.

-Thanks in advance.

I don't think they have any way of knowing that the clocks have been changed, either up or down. As long as you don't change the speeds by flashing the bios of course. MSI Afterburner seems to be the favourite tool for changing clocks.

I had to send three factory overclocked Gigabyte 560tis back due to artifacting. I found that when I lowered the memory frequency the problem went away.

Give the cards a good run on other games too just to make sure it's not BF3 only. The game I had huge problems with was Fallout NV.

Well done on keeping the temps to 61C with SLI by the way. I hit 95C withing 5 minutes with two of the Gigabyte SOC cards I had.

I really think what you are seeing, which is probably similiar to what I am seeing is a game issue and not a videocard issue. Hopefully NVidia will bring out a new driver or EA will patch the game. There are too many peeps posting about issues for it to be the cards, IMO.
 

+1, try to lower your clocks a little as Crysis 2 has some issues with OCed GPUs, anyway BF3 has some bugs and a lot of people waiting for a patch to fix it. Even more, BF3 has issues with nVidia cards more than AMD's.

I have not, only because I have heard that PNY does not honor the warranty even when you decrease the clock speed.

Hopefully this is the case. I have a friend that has a high end AMD card not sure of the model and says he has gotten lots of bugs too. As an update, I tried playing around with the settings in Nvidia control panel and since setting my Physics processing to the CPU (from Auto select) I haven't noticed the "artifacts".

I'm just a bit hesitant to lower clocks as I've heard PNY may not honor the warranty even when decreasing clock speed. If the problem persists after another patch I might try contacting them about it. Just curious as to the Nvidia cards having more issues than AMD cards, any substantiation?. Not doubting the validity, it's certainly possible but it just seems too early to tell. Any large-scale studies done? More graphical bugs or just lower performance on average?

Thanks for the info ilysaml. I'm aware that the cards automatically raise and lower their clock speeds at will when needed based on performance needs. This isn't underclocking or overclocking, nor is it what I was referencing. My concern was whether or not raising or lowering the maximum clock speeds that the cards can reach would be grounds for a voidable warranty. If there's no way for PNY to know that the clocks have been changed via software that's great. Keep in mind I'm a noob as this is my first PC build, so I may say things that are unreasonable or even nonsensical throughout my search for help.

And thanks for also providing the review regarding DX 10 cards and BF3 performance. It's interesting to the see the differences in the older cards.

Right, I should have used the term "factory overclock" and not "stock".

Thanks for the advice. I'll try out Crysis 2 with the BF 3 drivers I'm currently using and see if I see similar artifacts. I'll try rolling back to the BF 3 Beta drivers if needed. I actually do use MSI afterburner to keep tabs on my temps, so that's good news about clock changing. So would changing the voltage through Afterburner also be kept unknown? I don't plan on doing anything like that soon, but maybe in the future.

As for the temps, my highest card one time reached 81 degrees when running 3DMark11 but that was before moving my side fan to the bottom position and before I added an additional fan to blow air at a 45 degree angle from bottom right to upper left of my case. Seems to work pretty well.

The voltage through Afterburner would be the same story. They wouldn't know unless of course something went bang, fizzle, pop. I'm far too scared to mess with voltages personally.

I'd be interested to know if the problem goes away with a lower memory clock. It did for me but I wasn't happy running my card at less than factory speed so I got an EVGA instead.

Yea I'm kinda in the same boat as far as voltage goes. Don't want to mess with it really. So far I've been playing under the beta drivers for BF 3 285.38 and so far no artifacts.
